New BMW sub-brand: BMW i

* 21.02.2011
* Press Release
* UPDATE

Munich. The new BMW sub-brand focused on developing sustainable mobility solutions has been launched. “BMW i represents a new movement in premium mobility. With the introduction of this new sub-brand, the BMW Group reaffirms its leadership as the most innovative and sustainable premium car company. The products and services have been conceived around a revolutionary approach: purpose designed and purpose built for sustainable, premium mobility. It’s a new day in our industry; a new era for individual mobility. This is BMW i – Born Electric.” said Ian Robertson, member of the Board of Management of BMW AG responsible for Sales and Marketing, in Munich on Monday.

In a first move, two models will be launched under the new sub-brand from 2013 – the BMW i3 and BMW i8. The BMW Group will also significantly expand its range of mobility services over the years ahead. To achieve this, a Venture Capital company was founded in New York City, BMW i Ventures, with an investment totalling up to 100 million US dollars.

“BMW i offers visionary cars and services, inspiring design, and an entirely new concept of premium mobility – all with a focus on sustainability”, explained Robertson. The BMW i brand comprises vehicles and services developed since 2007 as part of project i, a BMW Group think tank exploring sustainable mobility solutions. It is the BMW Group’s response to changing customer needs, including increasing demand for alternative drive trains, such as electric drive systems and hybrids. There is a widespread desire in megacities for solutions which intelligently combine the benefits of various mobility concepts in a single package.


Revolutionary vehicle concepts

“With BMW i, we are building on the success and strength of our core brand,” emphasised Robertson. The BMW i3– previously known as the Megacity Vehicle – will be the BMW Group’s first series-produced car for urban areas to be driven by electric power alone. The BMW i8, meanwhile, is based on the BMW Vision EfficientDynamics concept study. Its plug-in hybrid drive blends the sporting ability of a high-performance machine with the fuel consumption and emissions of a small car.

Both models are based on a revolutionary construction concept known as LifeDrive architecture. An aluminium chassis houses the powertrain, and the passenger cell consists of high-strength but extremely lightweight carbon fibre-reinforced plastic (CFRP). “Both cars have been designed specifically for their respective alternative drive systems. We used the innovative architecture and CFRP to cancel out practically all of the extra weight added by the batteries. For our customers this means superior driving dynamics combined with significantly increased range using electric power,” explains Klaus Draeger, BMW Board member responsible for development.


BMW i8 to be built in Leipzig

Like the BMW i3, the BMW i8 will also be manufactured at BMW’s Leipzig plant. Around 400 million euros will be invested in new plant facilities and some 800 jobs will be created up to 2013. Development and production synergies will be achieved through both vehicles using the same component sets for the electric motors, power electronics, and high-voltage lithium-ion batteries.


A range of vehicle-independent services

An additional range of mobility services – which can also be used independently of the cars – will be an integral component of BMW i. This will allow the creation of a new, profitable area of business over the long term and attract new customers to the company’s brands.

“Mobility requirements are changing in rapidly expanding megacities” adds Ian Robertson. “Our commitment to car-enabled mobility services, like BMW ConnectedDrive, will be significantly expanded under BMW i. We’ll also grow our car-related premium mobility services. What’s truly groundbreaking is that we’ll begin offering car-independent premium mobility services. BMW i aims to provide customized mobility solutions across a seamless network of premium products and premium services.” The focus is on solutions which will improve usage of existing parking spaces, as well as intelligent navigation systems with local information, intermodal route planning, and premium car-sharing.

In addition to services developed in-house, the BMW Group is pursuing collaborations with partner companies and exploring strategic capital investments in providers of mobility services. To this end, the venture capital company BMW i Ventures has the goal to expand the range of products and services offered by BMW i in the long term by taking stakes in highly innovative service providers.

New York-based My City Way is the first company in which BMW i Ventures has taken a stake. Of the partnership, Ian Robertson said, “I am thrilled to announce that we have just signed our first strategic partnership with My City Way. As a mobile app, My City Way provides users with information on public transportation, parking availability, and local entertainment for over 40 cities in the US. Another 40 cities will be part of the global rollout, including Munich, of course.”

In a big fundamental change for the upcoming BMW i8, the future BMW halo car will be powered by a gasoline engine instead of diesel. It was previously intended to be powered by a 161-horsepower 1.5-liter 3-cylinder turbo DIESEL engine mated with a hybrid synchronous motor on the front axle (80HP) and full electric motor on the rear axle (51HP), to give a combined 292HP. The diesel motor will now be replaced by a traditional gasoline engine.

According to R&D chief Klaus Draeger (via Autocar), the i8 will instead be petrol (gasoline) powered in order appeal to the widest potential market. Says Draeger - the change is being made "as we want to sell it all over the world. Diesel is only really relevant to Europe”.

The i8 (along with the i3) were announced as the first models to be produced under the new BMW sub-brand "i" earlier this week. Both cars will be built at the Leipzig Plant. The i3 launches in 2013, the i8 shortly after.

The BMW Group showcases its visions of future mobility in the shape of the BMW i3 Concept and BMW i8 Concept studies. Unveiled for the first time, these concept vehicles provide a glimpse of the first electrically powered production cars from the new BMW i sub-brand, due to be launched as the BMW i3 in 2013 and the BMW i8 in 2014.

“We are marking another milestone in the history of the BMW Group. As Chairman of the Board and an engineer myself, I am very proud of this project,” declared Norbert Reithofer, Chairman of the Board of Management of BMW AG, at Friday’s premiere of the two vehicles in Frankfurt. “As the world’s leading premium car manufacturer, our aim is to offer customers purpose-built electric-drive cars as well,” he added.

With its zero-emission electric drive and a range of approximately 150 kilometres, the BMW i3 Concept has been specifically developed for use in an urban environment, its dynamic 125 kW electric motor and rear-wheel drive ensuring BMW-style dynamic handling. Thanks to its innovative LifeDrive architecture featuring a carbon passenger cell, the BMW i3 Concept combines an extremely low weight of 1,250 kilograms with optimal interior space and the highest crash safety levels. With four seats and a 200-litre luggage compartment, this vehicle is fully suited for everyday use.

The BMW i8 Concept goes from 0 to 100 km/h in less than five seconds and boasts fuel consumption of under three litres per 100 km. Its plug-in hybrid drive with a system output of 260 kW allows a range of up to 35 kilometres in electric mode – sufficient for most everyday journeys. For more dynamic driving or out-of-town routes, a high-performance three-cylinder petrol engine also comes into play. The sports car has an electronically governed top speed of 250 km/h and space for up to four occupants. “The BMW i8 Concept is the sports car for a new generation – pure, emotional and sustainable,” Draeger underlined.

With BMW i, the BMW Group is corroborating its position as the most innovative and sustainable auto manufacturer in the world, as reflected in the fact that it has been the supersector leader in the Dow Jones Sustainability Indexes for the sixth year running. With BMW i, the BMW Group is providing answers to the mobility challenges of the future while pursuing a holistic approach. In addition to purpose-built premium vehicles with electric drive, the company is also offering intelligent mobility services.

The focus here is on solutions for improved use of parking space, intelligent navigation systems with location-based information, intermodal route planning and car-sharing schemes such as DriveNow. Following MyCityWay, ParkatmyHouse marks the second investment by the recently launched venture capital company BMW i Ventures in a company providing internet-based mobility services. Parkatmyhouse allows private individuals to use the internet or a smartphone app to rent out their private parking spaces on a short- or long-term basis.

Both the BMW i3 and the BMW i8 will be built at BMW’s Leipzig plant in Germany. Some 400 million euros are earmarked for investment in new buildings and facilities by 2013, while 800 new jobs are to be created. Vehicle production will be CO2 neutral and will draw on renewable resources. The company is currently investigating the possibility of erecting its own wind turbines on the plant site.

The BMW i8 Concept Spyder with eDrive is an open-top two-seater embodying a form of personal mobility with equal sporting and emotional appeal.

Under the banner of its sub-brand BMW i, the BMW Group is developing a range of purpose-built vehicle concepts and complementary mobility services which meet the changing needs of customers and redefine the understanding of personal mobility. As well as adopting intelligent technologies and innovative design, BMW i is pursuing an all-embracing approach defined to a significant degree by sustainability throughout the value chain.

Following the presentation of the BMW i3 Concept and BMW i8 Concept, the BMW Group introduces the BMW i8 Concept Spyder to the mix. This third BMW i model embodies the future of cutting-edge and emotionally appealing mobility concepts. Its sporting design headlines the qualities of an open-top two-seater blending lightness, dynamic capability and efficiency with a very special aesthetic allure.

The combination of intelligent lightweight design and state-of-the-art hybrid technology imbues the BMW i8 Concept Spyder with genuine sports car performance, yet its fuel consumption is no higher than you would expect from a small car.

Among the most eye-catching features of the BMW i8 Concept Spyder are the upward-swivelling, windowless doors and a range of purpose-oriented on-board equipment including electric kickboards stowed under a transparent tailgate. The sports car is based around the innovative LifeDrive architecture, itself underpinned by a lightweight modular construction and the use of high-quality high-tech materials. The BMW i8 Concept Spyder is a plug-in hybrid powered by an eDrive drivetrain combining a high-performance electric motor and petrol combustion engine. The lithium-ion battery supplying the motor with power can be recharged in an extremely short space of time from any domestic power socket. Together, the car's minimised weight, low centre of gravity and finely judged balance, coupled with a combined system output of up to 260 kW (354 hp), promise unbeatable dynamic capability, exceptional efficiency and unbridled driving pleasure.

Barely a year after the unveiling of the 2+2-seater BMW i8 Concept, BMW i is presenting the second variant of this innovative hybrid sports car, a machine designed to light up the path to compelling and purpose-oriented mobility. Like its Coupe sibling, the emotionally charged BMW i8 Concept Spyder combines intelligent lightweight design with the leading-edge drivetrain technology eDrive, while its open-top two-seater construction delivers an even more intense driving experience. This is a car in which outstanding performance potential goes hand-in-hand with extremely low fuel consumption and emissions.

Compared with the Coupe variant of the BMW i8 Concept, the BMW i8 Concept Spyder has a slightly shorter wheelbase and overall length. With its compact dimensions and distinctive exterior paintwork, the sports car exudes a feeling of dynamism before it so much as turns a wheel, while striking features of its design include upward-swivelling, windowless doors and a transparent glass panel at the rear. Underneath this cover two electric kickboards are stowed, providing a visual showcase for the fun factor in mobility and adding another layer to the car's recreational appeal. Inside, a revised material and colour concept provides an extra dose of sportiness. Like the Coupe, the BMW i8 Concept Spyder with eDrive is a high-performance plug-in hybrid, and it fuses the specific advantages of an electric motor and combustion engine to optimum effect. Exceptional efficiency and dynamic capability are the upshot.

Modular LifeDrive architecture

Like the Coupe, the BMW i8 Concept Spyder is also built around the innovative LifeDrive architecture, a fusion of independent functional units. For example, the carbon-fibre-reinforced plastic (CFRP) Life module gives the car an extremely lightweight passenger cell, while the Drive modules – made primarily from aluminium components – bring together all the car's operational driving functions, such as the powertrain, chassis and safety structure. Impressively extensive use of high-tech materials allows this innovative concept to chart new territory in terms of weight minimisation, structural rigidity and crash safety. This is good news not only for the car's dynamic performance, but also for its range and fuel economy. Intelligent lightweight design, encompassing the use of innovative materials, has allowed the unavoidable additional weight of the high-output hybrid drivetrain to be cancelled out in full. Plus, the LifeDrive architecture has been carefully adapted to the sports car character of the BMW i8 Concept Spyder. The front and rear axle modules are connected by an "energy tunnel", which houses the hybrid battery. This allows the engineers to give the car a low centre of gravity and ideal balance.

The distinctive two-way split of the LifeDrive concept is also reflected in the car's design, which renders the basic elements of the body clearly distinguishable. Expressive surfaces and precise lines create a harmonious transition from one module into another. This overlap and interlocking of surfaces and lines – "layering" in BMW i speak – is displayed both on the body and in the interior of the new car.

BMW i design language.

The BMW i8 Concept Spyder's emotion-led design vividly spotlights the car's qualities, with lightness, dynamic capability and efficiency highlighted to particularly prominent effect. For example, the two-seater embodies the perfect synthesis of technology and aesthetic appeal, and exudes unbridled driving pleasure even when stationary. Key to creating this impression of sporty dynamics are large body panels, a hunkered-down stance and numerous aerodynamic elements such as contact surfaces, spoiler lips, AirCurtains and aeroflaps. These features substantially reduce the hybrid car's Cd and enhance both efficiency and range.

Dynamic front end.

The front end offers a particularly revealing window into the open-top two-seater's dynamic talent. One defining element is the headlights with pioneering laser light technology, which follow the hallmark BMW i U-shaped design template. A semi-transparent "V" opens out from the front end of the flat bonnet towards the windscreen and beckons the eye to the electric motor below. A spoiler lip positioned on the windscreen frame guides the airflow over the heads of the passengers. And for journeys when the weather cannot quite be trusted, the planned two-section folding roof might well come in handy.

Athletic silhouette.

Short front and rear overhangs and a low-slung silhouette define the side view of the BMW i8 Concept Spyder and underline its athletic character. Alluring lines and forms generate a strong forward-surging stance even before the car powers off the line. The doors, which open by pivoting forwards around the A-pillar axis, further enhance the BMW i8 Concept Spyder's emotional impact. Below the doors, the side skirts create a powerful wedge shape which opens out towards the rear. At the same time, the open-top two-seater cuts a light and flowing figure and appears as if carved from a single mould.

Striking rear.

Like the front end, the rear also sits low to the road. Its headline feature is a transparent cover revealing the two folded electric kickboards accommodated below. Adopting the hallmarks of BMW i design, the kickboards are perfect for relaxed cruising along promenades and paths or around city squares. There can be few more attractive advertisements for individual mobility. A visually imposing rear diffuser, three-dimensional air outlets and the U-shaped rear lights give the BMW i8 Concept Spyder an extremely wide appearance and emphasise its sporting credentials.

Layering in the interior.

The interior of the BMW i8 Concept Spyder is defined by three levels showcasing its various functions. As with the car's body, the interlocking of surfaces and lines is also one of the stand-out features of the interior design. The outer layer frames the supporting structure, while the inner "comfort" layer comprises seat surfaces and stowage compartments. The cockpit fills the third "technical" layer, bringing together the instrument panel, steering column and steering wheel with the instrument cluster, central information display and control elements. The prominent driver focus of the cockpit and the low seating position, which adds further depth to the open-top two-seater's credibility, are particularly eye-catching. All the controls are in just the right position and, like the other functional components of the interior, designed to further enliven the driving experience. An 8.8-inch (22.4 cm) screen displays all the relevant driving information in three-dimensional, high-resolution quality.

The colour and materials concept also provides some stand-out touches. The Spyder's interior is defined by a mixture of plastic, carbon and leather, with the off-white of the outer layer and the bold orange tone of the naturally tanned leather generating a sporting atmosphere rich in contrast. The cockpit and centre console also show slight modifications over the Coupe. The overall effect of the interior is one of quality, purity and emotional appeal.

Plug-in hybrid

Like the Coupe, the BMW i8 Concept Spyder with eDrive is a plug-in hybrid combining two different power sources and employing the specific advantages of its electric motor and combustion engine to optimum effect. The hybrid drivetrain's key components gel together with outstanding smoothness, allowing it to offer peerless dynamic capability and maximum efficiency. In other words, the open-top two-seater produces the performance of an out-and-out sports machine yet posts the fuel economy of a small car.

The 96 kW (131 hp) electric motor on the front axle works in tandem with a turbocharged three-cylinder petrol engine sending 164 kW (223 hp) through the rear wheels. Both units are in-house BMW Group developments and generate an aggregate system output of 260 kW (354 hp) and peak torque of 550 Newton metres. That is enough to accelerate the BMW i8 Concept Spyder from 0 to 100 km/h (62 mph) in five seconds on the way to an electronically governed top speed of 250 km/h (155 mph). Despite this performance, the two-seater burns just three litres of petrol per 100 kilometres (equivalent to fuel economy of 94 mpg imp) in the European test cycle.

The electric motor sources its energy from a lithium-ion battery which can be fully charged from a domestic power socket in less than two hours. The high-output battery is located in the energy tunnel between the front and rear axle modules in order to keep the car's centre of gravity as low as possible – and therefore to maximise the car's dynamic performance. The space-saving and well-balanced packaging of this and other drive and chassis components gives the sporting two-seater ideal 50:50 weight distribution.

With its battery fully charged, the BMW i8 Concept Spyder can cover up to 30 kilometres (19 miles) on electric power alone. As such, far from filling in as a bit-part player, the electric motor plays a role equal to that of the petrol engine. If required, a high-voltage alternator hooked up to the combustion engine generates extra power, which is then stored in the hybrid battery. This range-extending function during the course of a journey allows the two-seater to travel further between charging stations.

Another special feature of the BMW i8 Concept Spyder is the ability to send power through the front, rear or all four wheels at the same time. Intelligent control electronics ensure that the optimum drive configuration is available for the situation at hand. The driver can view the driving mode currently engaged and monitor the activity of the two drive sources on the large information display in the cockpit. Furthermore, the electronic systems ensure maximum energy recuperation under braking or when coasting. All of which means that the driver can enjoy maximum dynamic performance, unbeatable directional stability and minimal consumption and emissions at all times.

Connectivity

BMW i sums up the idea of mobility geared to the demands of the future and the needs of its customers. To this end, BMW i drivers will have a new generation of driver assistance systems at their disposal which significantly enhance both safety and comfort. For example, the camera-based proactive Collision Warning system, Parking Assistant and Traffic Jam Assistant ensure all on board can enjoy a safe and relaxed journey.

In addition, BMW i is developing an array of innovative connectivity functions which provide a seamless link between its models and their owners' lives outside the car. Remote functions accessed via a smartphone help users to locate their car in large car parks (CarFinder), show nearby charging stations, allow the battery to be charged at pre-set times and inform drivers on the current status of their vehicle. Plus, the battery and interior can be brought up to peak operating temperature before the driver sets off on a journey. The Last Mile Navigation function, meanwhile, assists drivers after they have parked their car, with route instructions transferred directly onto their smartphone directing them along the last leg of their journey on foot – to a museum or restaurant, for example. And the Intermodal Route Planning function effectively integrates the car into the local public transport network and provides information on current parking availability at the driver's destination.

Interface

Two large displays inside the BMW i8 Concept Spyder make up the interface between the car, its passengers and the outside world. Positioned alongside the instrument cluster behind the steering wheel, the central information display flags up all relevant information and assists the driver in the use of connectivity applications. A third display shows the automatic climate control settings currently engaged. All the screens display their information in 3D, and the cutting-edge, visually appealing graphics are also impressively clear.

Instrument cluster

The instrument cluster displays important driving data using two variable-form ellipses. Positioned alongside the digital speedometer, the efficiency display allows drivers to view how much energy they are currently using – or recovering through the recuperation process. Added to which, the display also contains extra navigation details and information on the car's range when running purely on electric power, its range when powered by the combustion engine alone and its range using both power units in tandem. If the driver switches to energy-saving ECO PRO mode, the display turns blue in colour to signal the shift in functional emphasis, and the ellipses now also vary in form. By the same token, moving into SPORT mode treats the driver to an emotional orange hue. As well as the changes in colour, the displays also provide information tailored to the driving mode selected and to assisting the driver as effectively as possible.

Central information display.

The central information display in the BMW i8 Concept Spyder makes a key contribution to intelligent mobility. It allows the driver to view the current status of the hybrid system, provides a platform for menu navigation and route guidance, and uses innovative connectivity functions to offer drivers a gateway into their lives outside the car. This ensures drivers remain up to speed at all times on how the combustion engine and electric motor are being used, while also being able to monitor the energy flow within the system.

Analysis of the driving situation.

The car's power electronics are linked up to intelligent navigation and traffic guidance systems to enable the hybrid drive system to work at maximum efficiency. In this way, information on route profile, speed limits and unavoidable traffic congestion are incorporated into the calculations of the energy management system so that the hybrid system's operating strategy can be adapted accordingly. For example, proactive charging of the hybrid battery allows the BMW i8 Concept Spyder to negotiate a traffic tailback on the road ahead using electric power alone – and therefore without producing any emissions. In addition, handy displays such as fuel consumption history allow interesting reflections on past journeys and help to optimise the driving style of the individual at the wheel.

BMW has published a full set of technical details about the i8 plug-in hybrid sports car that will debut at next month's Frankfurt Motor Show.

Previewed by a concept that debuted at the 2011 edition of the Frankfurt show, the production-bound i8 stretches 184 inches long, 76 inches wide and 50 inches tall. It is powered by a hybrid drivetrain that consists of a 231-horsepower 1.5-liter three-cylinder engine located behind the rear seats and a 131-horsepower electric motor mounted on the front axle. The gas-burning engine sends power to the rear wheels via a six-speed automatic transmission while the electric motor spins the front wheels through a two-stage automatic gearbox.

Rated at a combined 362 horsepower and 420 lb-ft. of torque, the plug-in hybrid drivetrain propels the i8 from zero to 62 mph in 4.5 seconds and on to a top speed of 155 mph. Alternatively, the i8 can operate on electricity alone for up to 22 miles at speeds of up to 75 mph.

With both power sources engaged, the i8 returns roughly 113 mpg in a mixed European cycle while emitting less than 59 grams of CO2 per kilometer, figures that make it cleaner than even the smallest, most frugal economy car in Europe.

Like the city-friendly i3, the central part of the i8 is a LifeDrive architecture that puts a heavy emphasis on lightweight materials. Crafted out of aluminum, the Drive module includes the gas-burning engine, the electric motor, the lithium-ion battery pack and all electronics. The Life module is built out of carbon fiber-reinforced plastic (CFRP) and mainly consists of the 2+2 passenger ccompartment. As a result, the car tips the scale at about 3,200 pounds and boasts a perfect 50/50 weight distribution.

A full set of details about the BMW i8 will be available in the weeks leading up to the Frankfurt Motor Show. Look for the plug-in hybrid sports car to land in United States showrooms in late 2014.

The BMW i brand is synonymous with visionary mobility concepts and a new definition of premium quality that is strongly focused on sustainability. Following the world debut of the first production model, the BMW i3, the BMW Group’s next step will be to extend this revolutionary answer to the future challenges facing personal mobility to the sports car segment. At a driving event at the BMW Group’s Miramas test track in France, the BMW i brand is now presenting a prototype of its second production vehicle, the BMW i8. This plug-in hybrid model is the most progressive sports car of our time, extending the basic BMW i philosophy of sustainability to a new vehicle segment.

The BMW i8 embodies hallmark BMW driving pleasure in a revolutionary and mould-breaking form. This is reflected in a highly emotive design, dynamic sports car performance, and fuel consumption and emissions figures worthy of a small car. Pairing an exceptionally lightweight, aerodynamically optimised body with cutting-edge BMW eDrive technology, a compact, highly turbocharged 1.5-litre BMW TwinPower Turbo petrol engine and intelligent energy management, the BMW i8 marks the next stage in the evolution of the Efficient Dynamics strategy. Its revolutionary approach achieves an unprecedented balance between performance and fuel consumption. Thanks to its carbon-fibre-reinforced plastic (CFRP) passenger cell, the BMW i8 sets new standards for a plug-in hybrid vehicle in terms of low weight. It can operate solely on electric power, which means no tailpipe emissions, and offers the dynamic performance of a sports car, with an expected 0 – 100 km/h (62 mph) sprint time of 4.5 seconds.

The BMW i8 was designed from the outset as a plug-in hybrid sports car, with the emphasis on agile performance and outstanding efficiency. Its characteristic BMW i LifeDrive architecture provides the best possible basis for lightweight design. Its main components are the aluminium Drive module, which incorporates the internal combustion engine and electric motor, the battery, the power electronics and the chassis components, along with structural and crash functions, and the Life module, which essentially comprises the 2+2-seater CFRP passenger cell. This architecture also gives the BMW i8 a very low centre of gravity and a near-perfect 50:50 axle load ratio, both of which increase its agility.

1. The best of both worlds: The BMW i8 – powertrain, lightweight design and driving experience.

The BMW i8’s plug-in hybrid system is specific to this model. Developed and produced by the BMW Group, it marks the next step in the evolution of the Efficient Dynamics programme. A compact three-cylinder petrol engine with BMW TwinPower Turbo technology is combined with an electric drive system and a lithium-ion battery which can be recharged at a standard household power socket. The 170 kW/231 hp petrol engine sends its power to the rear wheels, while the 96 kW/131 hp electric motor powers the front wheels. This configuration offers all-electric driving capability with a range of up to 35 kilometres (approx. 22 miles) and a top speed of 120 km/h (approx. 75 mph). With both drive systems engaged, it also offers road-hugging all-wheel-drive performance with powerful acceleration and dynamic torque vectoring during sporty cornering. The more powerful of the two powerplants drives the rear wheels. The hybrid system supplements this with power from the electric motor to deliver typical BMW driving pleasure combined with groundbreaking efficiency. Calculated using the EU test cycle for plug-in hybrid vehicles, the average fuel consumption of the BMW i8 at model launch will be less than 2.5 litres/100 km (over 113 mpg) with CO2 emissions of less than 59 grams per kilometre.

Optimal balance between performance and fuel economy: BMW i8 as an exciting evolution of the Efficient Dynamics strategy. It is now more than a decade since the BMW Group launched its Efficient Dynamics vehicle development strategy, whose aim is to significantly improve both the performance and the efficiency of new BMW Group models. Efficient Dynamics combines evolutionary advances in existing technologies with the development of new and revolutionary drive concepts. Efficient Dynamics solutions include efficient lightweight design and aerodynamic concepts, high-performance drive systems based on TwinPower Turbo technology and BMW eDrive, and intelligent management of all energy flows within the vehicle. The new, revolutionary technology now being introduced on models of the BMW i brand will subsequently find its way into the vehicles of the BMW Group’s core brands.

BMW i is also setting benchmarks in the quest for zero CO2 emissions in urban driving. The research and development work carried out since 2007 as part of project i has laid the foundations for revolutionary mobility solutions strongly influenced by environmental, economic and social change around the world. The BMW Group is pursuing an integrated approach, as embodied in the new BMW i brand, which aims to achieve the necessary balance between individual needs and the global mobility requirements of the future. The BMW i focus is squarely on all-electric and plug-in hybrid mobility. Groundbreaking design, intelligent lightweight engineering, typical BMW driving pleasure coupled with zero emissions, intelligent energy management and resource- and energy-saving production processes are all combined into an innovative premium-quality package.

LifeDrive architecture with an aluminium chassis for the powertrain and a CFRP passenger cell: for more excitement, lower weight and optimised drag. The LifeDrive architecture specially developed for BMW i vehicles offers the ideal platform for turning the tide of spiralling weight while at the same time achieving distinctive styling exclusive to BMW i. With a length of 4,689 mm, a width of 1,942 mm and a height of 1,293 mm, the BMW i8 has the proportions of a typical sports car. Its dynamic personality is also stressed by a long bonnet, conspicuous aerodynamic features, an elongated roofline, short overhangs and a long wheelbase of 2,800 mm. Characteristic BMW i form language wraps up this groundbreaking combination of sporty performance and efficiency in a charismatic 2+2-seater design.

The BMW i8 combines a drag coefficient (Cd value) of 0.26 with outstanding aerodynamic balance. The finely honed air flow around all parts of the vehicle body makes for an excellent lift/drag ratio, resulting in superb driving dynamics and stability.

Intelligent lightweight design – from the overall concept down to the smallest detail. With its combination of the aluminium Drive module and the CFRP passenger cell (Life module), the BMW i8 is also an excellent example of intelligent lightweight design – one of the guiding principles of the Efficient Dynamics strategy. Use of the lightweight high-tech material CFRP, which also offers excellent crash performance, brings weight savings of 50 per cent over steel and around 30 per cent over aluminium, with equivalent or improved strength. These savings offset the weight penalty of the electric motor and the high-voltage battery, giving the BMW i8 an unladen weight of less than 1,490 kilograms. The LifeDrive architecture also brings benefits in terms of weight distribution. The battery pack is situated low down in the middle of the vehicle, resulting in a low and central centre of gravity, which improves safety. No other current model of a BMW Group brand has such a low centre of gravity.

The front-rear axle load distribution maximises agility with a near-perfect 50:50 axle load ratio. The compact electric motor, together with the transmission and power electronics, are situated in close proximity to the electrically powered front axle. The highly turbocharged petrol engine, which is located together with its transmission in the rear of the BMW i8, likewise sends its power to the road via the shortest possible route, i.e. through the rear wheels. As a finishing touch to this excellent weight distribution, the lithium-ion battery pack is centrally located in the vehicle, slightly forward of the mid-point. In terms of crash safety, this is an ideal location for the battery, which is integrated in an aluminium housing.

The doors comprise a CFRP inner structure and an aluminium outer skin. This reduces the weight of the door by 50 per cent compared with a conventional design. The high-quality, naturally tanned leather of the seats highlights the “next premium”, sustainable philosophy of BMW i.

The magnesium instrument panel support saves weight on two fronts – firstly through intelligent design, leading to around 30 per cent weight savings compared, for example, with the BMW 6 Series. In addition, the high structural rigidity provides a strengthening effect which allows the number of components to be reduced, thereby lowering weight by a further 10 per cent. Innovative foam plastic technology used in the air conditioning ducts brings 60 per cent weight savings over conventional components, while also improving acoustics thanks to its sound-absorbing properties.

The fact that the power electronics and electric motor are directly connected reduces the amount of wiring required, while partial use of aluminium wiring brings further weight reductions. Lightweight design is also a feature of the BMW i8’s chassis systems – including the wheels, where the standard-fitted 20-inch forged aluminium wheels combine aerodynamic design with weight savings. The rigorous application of the lightweight design strategy even extends to aluminium screws and bolts, which are around 45 per cent lighter than corresponding steel components, with the same strength and functionality.

The BMW i8 is also the world’s first volume-produced vehicle to be equipped with chemically hardened glass. This innovative technology, to date used mainly in Smartphone manufacturing, results in very high strength. The partition between the passenger compartment and boot of the BMW i8 consists of two layers of chemically hardened glass, each of which is just 0.7 millimetres thick, with acoustic sheeting sandwiched between. In addition to excellent acoustic properties, a further advantage of this solution is weight savings of around 50 per cent compared with conventional laminated glass.
For maximum driving pleasure and efficiency: BMW TwinPower Turbo engine and electric motor developed by the BMW Group. The plug-in hybrid system of the BMW i8, which comprises a BMW TwinPower Turbo engine combined with BMW eDrive technology, offers the best of both worlds: excellent potential for improved efficiency and exciting, sporty driving characteristics. The BMW Group has developed not only the internal combustion engine and electric motor in-house but also the power electronics and the battery. This ensures that all these components offer high product and quality standards, based on the outstanding capabilities of the BMW Group in the field of powertrain research and development.

The revolutionary character of the BMW i8 is emphasised by a further innovation: the use of a new internal combustion engine which is making its debut in this model. The BMW i8 is the first BMW production model to be powered by a three-cylinder petrol engine. This highly turbocharged unit is equipped with latest-generation BMW TwinPower Turbo technology. It is exceptionally compact and develops maximum power of 170 kW/231 hp. The resulting specific output of 113 kW/154 hp per litre of displacement is on a par with high-performance sports car engines and is the highest of any engine produced by the BMW Group.

The new three-cylinder engine derives its typical characteristics from the BMW six-cylinder in-line engines, to which it is closely related and which are noted for their eager power delivery, revving ability and refinement. The three-cylinder’s BMW TwinPower Turbo technology comprises a high-performance turbocharging system and direct petrol injection with high-precision injectors positioned between the valves, along with VALVETRONIC throttle-less load control, which improves efficiency and response thanks to seamlessly variable valve lift control. Like a six-cylinder engine, the three-cylinder unit is free of first and second order inertial forces. The low roll torque, a typical feature of a three-cylinder design, is further reduced by a balancer shaft, while a multi-stage damper integrated in the automatic transmission ensures very smooth and refined running at low rpm. BMW TwinPower Turbo technology and low internal friction improve both fuel consumption and torque characteristics. Accelerator response is sharp and the three-cylinder unit quickly reaches its maximum torque of 320 Newton metres.

The BMW i8’s second power source is a hybrid synchronous electric motor specially developed and produced by the BMW Group for BMW i. The electric motor develops maximum power of 96 kW/131 hp and produces its maximum torque of around 250 Newton metres from standstill. Typical of an electric motor, responsive power is instantly available when starting and this continues into the higher load ranges. The linear power delivery, which extends right up to the high end of the rpm range, is down to a special motor design principle exclusive to BMW i. BMW eDrive technology refines and improves on the principle of the permanently excited synchronous motor via a special arrangement and size of the torque-producing components. This results in a self-magnetising effect normally confined to reluctance motors. This additional excitation ensures that the electromechanical field generated when current is applied remains stable even at high rpm.

As well as providing a power boost to assist the petrol engine during acceleration, the electric motor can also power the vehicle by itself. Top speed is then 120 km/h (approx. 75 mph). The BMW i8 has a maximum driving range in this emission-free, virtually soundless, all-electric mode of up to 35 kilometres (approx. 22 miles). The motor derives its energy from the lithium-ion battery which is centrally mounted underneath the floor of the vehicle. The model-specific version of the high-voltage battery was developed and produced by the BMW Group. It has a liquid cooling system and can be recharged at a conventional household power socket, at a BMW i Wallbox or at a public charging station. A full recharge takes less than three hours at a household power socket and less than two hours at a BMW i Wallbox.
The BMW i8’s vehicle concept and powertrain control system mark it out as a progressive, revolutionary sports car. The BMW i8 always achieves the optimal balance between performance and efficiency, whatever the driving situation. When power demands allow, the high-voltage battery is recharged by the electric motor. The high-voltage starter-generator, responsible for starting the engine, can also be used as a generator to charge the battery, the necessary power being provided by the BMW TwinPower Turbo engine. The battery can also be recharged via the electric motor during overrun. These various processes help to prevent depletion of the BMW i8’s battery in order to maintain the electric drive power. The all-electric driving range is sufficient to cover most urban driving requirements. Out of town, the BMW i8 offers impressively sporty performance which is also very efficient thanks to the power-boosting support for the petrol engine from the electric motor. With such versatility, the BMW i8 belongs to a new generation of sports cars which unites exciting performance with cutting-edge efficiency – to enhance both driving pleasure and sustainability.

Driving Experience Control and eDrive button: a choice of efficiency and performance characteristics – at the touch of a button. The rear wheels of the BMW i8 are driven by the petrol engine via a six-speed automatic transmission. The front wheels are driven by the electric motor via an integrated two-stage automatic transmission. Combined maximum power and torque of 266 kW/362 hp and 570 Newton metres respectively provide all-wheel-drive performance which is as dynamic as it is efficient. The BMW i8’s intelligent powertrain control system ensures perfect coordination of both power sources. The variable power-sharing between the internal combustion engine and the electric motor makes the driver aware of the sporty temperament of the BMW i8 at all times, while at the same time maximising the energy efficiency of the overall system. Utilising both power sources, the 0 – 100 km/h (62 mph) acceleration time is expected to be less than 4.5 seconds. Linear acceleration is maintained even at higher speeds since the interplay between the two power sources efficiently absorbs any power flow interruptions when shifting gears. The BMW i8 has an electronically controlled top speed of 250 km/h (155 mph), which can be reached and maintained when the vehicle operates solely on the petrol engine. Variable front-rear power splitting in line with changing driving conditions makes for excitingly dynamic cornering. On entering the corner, the power split is biased towards the rear wheels to improve turning precision. For more vigorous acceleration out of the corner, the powertrain controller returns to the default split as soon as the steering angle becomes smaller again. The BMW i8 also offers the driver unusual scope to adjust the drive and suspension settings of the vehicle in order to adapt the driving experience to his or her individual preferences. As well as the electronic gear selector for the automatic transmission, the driver can also use the Driving Experience Control switch – a familiar feature of the latest BMW models – or, exclusively to the BMW i8, the eDrive button.

Using the gear selector, the driver can either select position D for automated gear selection or can switch to SPORT mode. SPORT mode offers sequential manual gear selection and at the same time switches to very sporty drive and suspension settings. In SPORT mode, the engine and electric motor deliver extra-sharp performance, accelerator response is faster and the power boost from the electric motor is maximised. And to keep the battery topped up, SPORT mode also activates maximum energy recuperation during overrun and braking: for this, the electric motor’s generator function, which recharges the battery using kinetic energy, switches to a more powerful setting. At the same time, gear change times are shortened and an extra-sporty setting is selected for the standard-fitted Dynamic Damper Control. Also in this mode, the programmable instrument cluster supplies further driving-related information in addition to the rev counter display.

The Driving Experience Control switch on the centre console offers a choice of two settings. On starting, COMFORT mode is activated, which offers a balance between sporty performance and fuel efficiency, with unrestricted access to all convenience functions. Alternatively, at the touch of a button, ECO PRO mode can be engaged, which, on the BMW i8 as on other models, supports an efficiency-optimised driving style. The powertrain controller coordinates the cooperation between the petrol engine and the electric motor for maximum fuel economy. On overrun, the intelligent energy management system automatically decides, in line with the driving situation and vehicle status, whether to recuperate braking energy or to coast with the powertrain disengaged. At the same time, ECO PRO mode also programs electrical convenience functions such as the air conditioning, seat heating and heated mirrors to operate at minimum power consumption – but without compromising safety. The maximum driving range of the BMW i8 on a full fuel tank and with a fully charged battery is over 500 kilometres (310 miles) in COMFORT mode. In ECO PRO mode, this can be increased by up to 20 per cent.

The BMW i8’s ECO PRO mode can also be used during all-electric operation. The vehicle is then powered solely by the electric motor. Only if the battery charge drops below a given level, or under sudden intense throttle application (kickdown), is the internal combustion engine automatically activated.
The driving mode selected at a given moment is indicated to the driver on the programmable instrument cluster by a distinctive colour and by a different, mode-specific set of driving information. The three-dimensional appearance of the display adds to the futuristic look and feel of the vehicle as a whole.
High-quality chassis technology, DSC and Dynamic Damper Control as standard. The high-end chassis and suspension technology of the BMW i8 is based on a double-track control arm front axle and a five-link rear axle, whose aluminium components and geometry are specially configured for intelligent weight savings. The electromechanical power steering offers easy manoeuvring in town and typical sports car-style high-speed steering precision. Also standard is Dynamic Damper Control: the electronically operated dampers change their characteristics according to the selected driving mode to deliver the desired vehicle dynamics.

The DSC (Dynamic Stability Control) stability system includes the Anti-lock Braking System (ABS), Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake Assist, Brake Standby, Start-Off Assistant, Fading Compensation and the Brake Drying function. The push button-activated Dynamic Traction Control (DTC) system raises the DSC thresholds, allowing some controlled drive wheel slippage for easier start-off on snow or loose ground, or for extra-dynamic cornering.
