Volkswagen: XL1 news **2014 Sport Version Revealed (page 1)**

Press release...

Future mobility is one of the most stimulating topics of our time. The key question here: Just how much could the energy consumption of cars be reduced if all the stops were pulled out for efficiency? There is now an answer to this question, and Volkswagen is delivering it in the form of the new XL1. Combined fuel consumption: 0.9 l/100 km. No other hybrid car powered by an electric motor / internal combustion engine combination is more fuel efficient. The prototype will be unveiled in a world debut at the Qatar Motor Show (26 - 29 January).

To the point

Conceptually, the XL1 represents the third evolutionary stage of Volkswagen’s 1-litre car strategy. When the new millennium was ushered in, Prof. Dr. Ferdinand Piëch, who is today Chairman of the Supervisory Board of Volkswagen AG, formulated the visionary goal of bringing to the market a production car that was practical for everyday use with a fuel consumption of 1.0 litre per 100 km. In the new XL1, Volkswagen is demonstrating that this goal is now within reach.

The new Volkswagen XL1 attains a CO2 emissions value of 24 g/km, thanks to a combination of lightweight construction (monocoque and add-on parts made of carbon fibre), very low aerodynamic drag (Cd 0.186) and a plug-in hybrid system - consisting of a two cylinder TDI engine (35 kW / 48 PS), E-motor (20 kW / 27 PS), 7-speed dual-clutch transmission (DSG) and lithium-ion battery. The results: with fuel consumption of 0.9 l/100 km, the new Volkswagen XL1 only emits 24 g/km CO2. Since it is designed as a plug-in hybrid, the XL1 prototype can also be driven for up to 35 kilometres in pure electric mode, i.e. with zero emissions at point of use. The battery can be charged from a conventional household electric outlet. Naturally, battery regeneration is also employed to recover energy while slowing down and store as much of it as possible in the battery for re-use. In this case, the electric motor acts as an electric generator.

Despite the very high levels of efficiency, developers were able to design a body layout that offers greater everyday practicality, incorporating side by side seating rather than the tandem arrangement seen in both the first 1-litre car presented in 2002 and the L1 presented in 2009. In the new XL1, wing doors make it easier to enter and exit the car. Further progress has been made by manufacturing body parts from carbon fibre reinforced polymer parts (CFRP), a technique used in Formula 1 car construction. Once again, Volkswagen has successfully achieved significant reductions in production costs– an important step forward to make viable a limited production run of the XL1. Background: together with suppliers, Volkswagen has developed and patented a new system for CFRP production in what is known as the aRTM process (advanced Resin Transfer Moulding).

II: The most efficient car in the world

The new XL1 shows the way forward for extreme economy vehicles and clean technologies. It also demonstrates that such cars can also be fun. The feeling when driving the XL1 is truly dynamic − not based on pure power, rather on its pure efficiency. Two examples: 1) To travel at a constant speed of 100 km/h, the prototype only needs 6.2 kW/8.4 PS – a fraction of the performance of today’s cars (Golf 1.6 TDI with 77 kW and 7-speed DSG: 13.2 kW/17.9 PS). 2) In electric mode, the XL1 needs less than 0.1 kWh (82 Wh/km) to complete a one kilometre driving course. These are record values.

When the full power of the hybrid system is engaged, the Volkswagen prototype accelerates from 0 to 100 km/h in just 11.9 seconds; its top speed is 160 km/h (electronically limited). Yet these numbers alone do not tell the whole story: Since the XL1 weighs just 795 kg, the drive system has an easy job of propelling the car. When full power is needed, the electric motor, which can deliver 100 Newton metres of torque from a standstill, works as a booster to support the TDI engine (120 Newton metres torque). Together, the TDI and E-motor deliver a maximum torque of 140 Newton metres in boosting mode.

III: Plug-in hybrid concept

With the new XL1, Volkswagen is implementing a plug-in hybrid concept, which utilises the fuel efficient technology of the common rail turbodiesel (TDI) and the dual clutch transmission (DSG). The TDI generates its stated maximum power of 35 kW/48 PS from just 0.8 litre displacement. The entire hybrid unit is housed above the vehicle’s driven rear axle. The actual hybrid module with electric motor and clutch is positioned between the TDI and the 7-speed DSG; this module was integrated in the DSG transmission case in place of the usual flywheel. The integrated lithium-ion battery supplies the E-motor with energy. The high voltage energy flow from and to the battery or E-motor is managed by the power electronics, which operates at 220 Volts. The XL1’s body electrical system is supplied with the necessary 12 Volts through a DC/DC converter.

Interplay of E-motor and TDI engine: The E-motor supports the TDI in acceleration (boosting), but as described it can also power the XL1 prototype on its own for a distance of up to 35 km. In this mode, the TDI is decoupled from the drivetrain by disengaging a clutch, and it is shut down. Meanwhile, the clutch on the gearbox side remains closed, so the DSG is fully engaged with the electric motor. Important: The driver can choose to drive the XL1 in pure electric mode (provided that the battery is sufficiently charged). As soon as the electric mode button on the instrument panel is pressed, the car is propelled exclusively by electrical power. Restarting of the TDI is a very smooth and comfortable process: In what is known as “pulse starting” of the TDI engine while driving, the electric motor’s rotor is sped up and is very quickly coupled to the engine clutch. This accelerates the TDI to the required speed and starts it. The entire process takes place without any jolts, so the driver hardly notices the TDI engine restarting.

When the XL1 is braked, the E-motor operates as a generator that utilises the braking energy to charge the battery (battery regeneration). In certain operating conditions the load shared between the TDI engine and the electric motor can be shifted so that the turbodiesel is operating at its most favourable efficiency level. The gears of the automatically shifting 7-speed DSG are also always selected with the aim of minimising energy usage. The engine controller regulates all energy flow and drive management tasks, taking into account the power demanded at any given moment by the driver. Some of the parameters used to realise the optimum propulsion mode for the given conditions are: accelerator pedal position and engine load, as well as the energy supply and mix of kinetic and electrical energy at any given time.

Two-cylinder TDI uses mass production technology: The 0.8 litre TDI (35 kW/48 PS) was derived from the 1.6 litre TDI, which drives such cars as the Golf and Passat. The 0.8 TDI exhibits the same data as the 1.6-litre TDI common rail engine in terms of cylinder spacing (88 mm), cylinder bore (79.5 mm) and stroke (80.5 mm). In addition, the XL1’s two-cylinder and the mass produced four cylinder share key internal engine features for reducing emissions. They include special piston recesses for multiple injection and individual orientation of the individual injection jets.

The excellent, smooth running properties of the common rail engines were transferred to the two cylinder engine. within addition, a balancer shaft that is driven by the crankshaft turning at the same speed optimises smooth engine running.

Meanwhile, the TDI’s aluminium crankcase was constructed to achieve high rigidity and precision, which in turn leads to very low friction losses. With the goal of reducing emissions, exhaust gas recirculation and an oxidation catalytic converter as well as a diesel particulate filter are used. Equipped in this way, the 0.8 TDI already fulfils the limits of the Euro-6 emissions standard.

Also designed for efficiency is the vehicle’s cooling system. Engine management only cools the TDI by activating an externally driven electric water pump when engine operating conditions require it. This cooling system includes an automatically controlled air intake system at the front of the vehicle to reduce cooling system drag. This thermal management strategy also contributes towards reduced fuel consumption. A second electric water pump, which is also used only as needed, circulates a separate lower temperature coolant loop to cool the starter generator and power electronics.

IV: CFRP body is a technical masterpiece

The development team made extraordinary strides in designing the CFRP body − in terms of its lightweight construction as well as its aerodynamics. A comparison to the Golf illustrates just how innovative the body concept of the new XL1 is:

The drag coefficient of the highly successful Golf is very good for the compact class: Cd (0.312) x A (frontal area 2.22 m2) equals a total drag figure of 0.693 m2 (Cd.A) providing this car with benchmark aerodynamic credentials in its class. Meanwhile, the XL1 exceeds this performance with a Cd value of 0.186 and a frontal area of 1.50 m2. The product of these two parameters yields a total drag, or Cd.A value of 0.277 m2 which is 2.5 times lower than that of the Golf.

Design for a new era: The new XL1 is 3,888 mm long, 1,665 mm wide and just 1,156 mm tall. These are extreme dimensions. The Polo has a similar length (3,970 mm) and width (1,682 m), but it is significantly taller (1,462 mm). The height of the new XL1 is about the same as that of a Lamborghini Gallardo Spyder (1,184 mm). So, it is easy to visualise just how spectacular such a Volkswagen would appear on the road – as long and wide as a Polo, but with a low profile like a Lamborghini.

The wing doors of the new XL1 are also reminiscent of a high-end sports car. They are hinged at two points: low on the A-pillars and just above the windscreen in the roof frame, so they do not just swivel upwards, but slightly forwards as well. The doors also extend far into the roof. When they are opened, they free up an exceptionally large amount of entry and exit space.

Visually, the new XL1 also adopts the styling lines of the L1 presented in 2009; however, the new prototype has a more dynamic appearance thanks to its greater width. The design of the entire body was uncompromisingly subjected to the laws of aerodynamics. In front, the new XL1 exhibits the greatest width; the car then narrows towards the rear. Viewed from above, the form of the XL1 resembles that of a dolphin; especially at the rear, where the lines optimally conform to the air flow over the car body to reduce the Volkswagen’s aerodynamic drag.

In side profile, the roofline reflects styling lines that trace an arc from the A-pillar back to the rear. The rear wheels are fully covered to prevent air turbulence; the air flows here are also optimised by small spoilers in front of and behind the wheels. Observers will look for door mirrors in vain; replacing them on the wing doors are small cameras which take on the role of digital outside mirrors that send images of the surroundings behind the car to two displays inside the vehicle.

The front end of the new XL1 no longer exhibits the typical radiator grille; however, it still reflects the styling of the current Volkswagen “design DNA” with a predominance of horizontal lines. Specifically, there is a black cross-stripe (in the area where there is no longer a radiator grille) that combines with the energy-efficient dual LED headlights to form a continuous band. The actual air intake for cooling the TDI engine, battery and interior is located in the lower front end section and has electrically controlled louvres. The narrow turn indicators are also designed in LED technology; these form an “L” shape which vertically follows the wheel housing and horizontally a line beneath the headlights. This creates a front end, which – although it is completely redesigned and extreme in its dimensions – can immediately be recognised as a Volkswagen design by its clean lines.

At the rear, the design takes an entirely new path, reinterpreting the brand values of precision and quality. A new dimension of Volkswagen styling was created here. Four characteristics are discernible:

1. Once again, the dolphin body form that narrows towards the rear with very precise trailing edges for perfect aerodynamics.
2. The coupé-shaped roofline without rear windscreen. Merging into the roofline is the large rear boot lid that covers the drive unit and 100 litre luggage space.
3. A strip of red LEDs that frames the rear section at the top and on the sides. Integrated in this LED strip are the reversing lights, rear lights, rear fog lights and brake lights.
4. A black diffuser, which exhibits nearly seamless transitions to the completely covered underbody.

Lightweight construction: more systematic than ever: Large sections of the new XL1’s body consist of carbon fibre reinforced polymer (CFRP) − which is as lightweight as it is strong. Specifically, the monocoque with its slightly offset seats for driver and passenger and all exterior body parts are made of CFRP. The layers of carbon fibre, which are aligned with the directions of forces, are formed into parts with an epoxy resin system in the aRTM process. This material mix produces an extremely durable and lightweight composite. For a long time, it was considered impossible to manufacture a body of CFRP, like that of the new XL1, to industrial standards. Nonetheless, Volkswagen successfully found a cost-effective way to mass produce CFRP parts in sufficient volumes as early as 2009 – in the framework of the XL1 development project. Now this process has been further perfected.

CFRP is the ideal material for the body of the new XL1 because of its light weight. The XL1 prototype weighs only 795 kg. Of this figure, 227 kg represents the entire drive unit, 153 kg the running gear, 80 kg the equipment (including the two bucket seats) and 105 kg the electrical system. That leaves 230 kg, which is precisely the weight of the body – produced largely of CFRP − including wing doors, front windscreen in thin-glass technology as in motorsport and the highly safe monocoque. A total of 21.3 percent of the new XL1, or 169 kg, consists of CFRP. In addition, Volkswagen uses lightweight metals for 22.5 percent of all parts (179 kg). Only 23.2 percent (184 kg) of the new XL1 is constructed from steel and iron materials. The rest of its weight is distributed among various other polymers (e.g. polycarbonate side windows), metals, natural fibres, process materials and electronics.

Lightweight construction: safer than ever: The new XL1 is not only lightweight, but very safe as well. As mentioned, this is due in part to the use of CFRP as a material. In the style of Formula 1 race cars, the Volkswagen has a high-strength monocoque. In contrast to Formula 1, however, this safety capsule is enclosed on top – for safety. Depending on the type of collision, the load path may be directed through the A- and B-pillars, cant rails and sills, all of which absorb the impact energy. Additional side members and crossmembers in the front and rear perfect the car’s passive safety.

V: Running gear with ESP utilises high-tech materials

The running gear is equipped with anti-roll bars at the front and rear and is characterised by lightweight construction with maximum safety. In front, a double wishbone suspension is used, while a semi-trailing link system is employed at the rear. The front and rear suspension are both very compact in construction and offer a high level of driving comfort. The running gear components mount directly to the CFRP monocoque in key areas.

Running gear weight has been reduced by the use of aluminium parts (including suspension components, brake calipers, dampers, steering gear housing), CFRP (anti-roll bars), ceramics (brake discs) magnesium (wheels) and plastics (steering wheel body). Friction-optimised wheel bearings and drive shafts, as well as an entirely new generation of optimised low rolling resistance tyres from MICHELIN (front: 115/80 R 15; rear: 145/55 R 16), contribute to the low energy consumption of the new XL1. Safety gains are realised by an anti-lock braking system (ABS) and electronic stabilisation programme (ESP). That is because sustainability without maximum safety would not really be a step forward. The new XL1 shows how these two parameters can be brought into harmony.

Kinda iffy on the exterior... It's got some retro and a lot of future... like something you'd see in The Incredibles. I'm all for fuel economy, but please put the side mirrors back on.

Interior is great, IMO. Classic, if a bit bare.

Fast-looking hybrid that does 0-60 in 11.something seconds, questionable interior... where have we seen this. The acceleration time alone will get this killed in the press.

Post Update


Just over 1 year ago, we heard reports suggesting that Volkswagen would actually be building a production version of its Formula XL1 concept for limited consumption. And while the skeptics among us were quick to dismiss these reports with a resounding "yeah, right," this latest set of spy shots show that Volkswagen is indeed making progress on an honest-to-goodness road-going model of its 1.0-liter fuel economy warrior.

It's still unclear exactly what will power the production XL1, though the concept car featured a 2-cylinder TDI diesel paired with an electric motor, lithium-ion battery pack and 7-speed dual-clutch transmission. All in, this is said to be good for an astonishing 235 miles per gallon. It might look big and sleek, but the XL1 is about as long and wide as a Volkswagen Polo. It should be ultra-light, too – the concept version tipped the scales at just 1,753 pounds.

The XL1 might look sleek and sporty, but performance will be anything but. The latest reports state that the production car will be limited to a stop speed of about 75 miles per hour, and that it'll take 32(!) seconds to shoot from a stand-still to 50 mph.

We'll keep our eyes peeled for future XL1 prototypes as development continues, but for now, scroll through our attached high-res image gallery to see the space-age VW for yourself.

If it can deliver anywhere near 200 MPG, and be at a decent price range...this will be a game changer.

Production model spotted in the wild.

Our spy photographers have just sent us the first pictures of Volkswagen’s production-intent XL1 plug-in hybrid. Seen hear undergoing hot weather testing, the spy shots show off the car’s gullwing doors and carbon fiber construction.

Marking the third-generation of Volkswagen’s ultra efficient concept, the XL1 is intended to be the company’s halo cars in terms of overall fuel economy. Unveiled in concept form at the 2011 Qatar Motor Showh, the XL1 follows in the footsteps of the One-Liter and L1 concept cars.

Highlighted by its sleek body shape, the XL1 registers a coefficient of drag figure of just 0.186. The XL1 has an overall length of 156.3 inches and, at 46.6 inches tall, is comparable in height to the Lamborghini Gallardo Spyder.

In order to overcome obvious blind spots, the XL1 will likely come fitted with external video cameras.

Inside the XL1 appears to be rather spartan with standard HVAC controls clearly visible on the car’s center stack. A large LCD screen is also present, but it remains unknown if that is production spec or simply a testing instrument.

Like the previous L1, the production-intent XL1 uses a 0.8L two-cylinder diesel engine mated to an electric motor. However, power has been increased from the previous concept, with the diesel engine generating 47 horsepower and the electric motor adding another 27 horsepower. Power is sent through a seven-speed dual-clutch gearbox.

Thanks to the extensive use of carbon fiber — as shown in these spy shots — the XL1 weighs just 1,650 pounds. Although designed of all-out efficiency, that light weight means the XL1 is a decent performer, with a 0-60 time of about 12 seconds and a top speed of 99mph.

In order to aid in efficiency, the XL1 is fitted with extremely narrow tires. The car also features a narrow rear track, which will likely carryover to the production car. However, the XL1′s rear wheels are expected to be covered for production.

As one would expect, the XL1’s plug-in powertrain and slick aero features deliver some eye-popping fuel economy figures. VW estimates that the production XL1 will be capable of achieving 235mpg.

Volkswagen will reportedly introduce the XL1 sometime during the first half of 2013.

but are people willing to pay a lot of money for a car that just has efficiency?? My guess would be no since people who can afford it probably doesnt care about gas.

my guess is this car won't be sold in US. This is meant for small streets of European cities, or China. Where people don't care about performance, just gas milage. Hell, they thing that a golf with a 2.0L engine is a gas guzzler

From here: Paris 2014. Volkswagen XL1 Sport | crankandpiston.com Car Culture Lifestyle

Those expecting a diesel/hybrid heavy Volkswagen stand at the 2014 Paris Motor Show did not leave disappointed. Petrolheads wrre however given a VW-shaped curveball with the unveil of the XL1 Sport, a dynamic derivative of the XL1 concept.

But whereas the XL1 was built specifically with fuel efficiency in mind, the Sport – as the name suggests – has been designed to offer ‘uncompromised driving dynamics’ as part of a collaboration with sister companies Ducati and Lamborghini. Like the XL1, the Sport will also be produced in limited numbers, 500 to the XL1′s 250.

The 1199cc V2 engine for the XL1 Sport has been lifted by Ducati’s 1199 Superlegerra superbike, the most powerful two-cylinder motorbike in the world. Said unit – which is capable of revving to 1100rpm – produces 200hp and 134Nm of torque, which is sent to the rear axles via VW’s seven-speed DSG gearbox. The XL1 Sport is thus capable of 0-100kph in 5.7 seconds and a 270kph top speed, subsequently making it the most fastest 200PS car in the world. Go ahead, see if you can name the others…

Though sharing similar design attributes of the its more fuel efficient brethren and the same carbon-reinforced polymer with a monocoque (a strong material that improves rigidity of the vehicle) and wing doors, there are some subtle differences. The Sport stands longer, wider and lower than the XL1 and boasts a longer wheelbase, all for a more balanced drive. Notable changes to the aerodynamics include ‘air cushions’ in the front which help channel cooling air to the wheels and ceramic disc brakes and new air ducts in the bonnet. The XL1 Sport also uses the same rear spoiler system as the Lamborghini Aventador. The Sport rolls on forged magnesium wheel, 23.0kg lighter than the equivalent aluminium variants as part of an overall 890kg base weight.

Press release...

There has never been a sports car like the XL Sport concept that is being shown for the first time by Volkswagen at the Paris Motor Show. This is a car that uncompromisingly furthers the development of the lightweight sports car. Based on the XL1, the most fuel-efficient production car of all time, this 168-mph machine is a compelling blend of efficiency and emotion.

The XL Sport houses one of the finest achievements in engine technology—the V-Twin adapted from the new Ducati 1199 Superleggera, the world's most powerful two-cylinder motorcycle. Like the XL1, of which only 250 will be built, the Superleggera is also being manufactured in a limited edition of 500 units, using a process that embraces hand fabrication and high-precision industrial manufacturing. The XL1 and the Superleggera, two icons of lightweight carbon and magnesium design technology, thus unite to create a unique sports car. With the XL Sport, Volkswagen and Ducati impressively demonstrate how high-tech developments can lead to synergies between Volkswagen Group brands.

Pioneering aerodynamics. The Ducati 1199 Superleggera has the best power-to-weight ratio of any production motorcycle in history. In the car world, the XL Sport achieves a similar record—the best ratio between weight (1962 pounds), power (147 kW/197 hp) and aerodynamics (CdA of 0.44 square meters). It’s a combination that allows the car to reach an impressive top speed of 168 mph on just 197 hp.

The vehicle's aerodynamics are one key reason the car performs so well. The coefficient of drag (Cd) of 0.258 and the low frontal area of 1.7 sq m combine to give a CdA of 0.44 sq m, one of the best values ever achieved and a major triumph for Volkswagen's aerodynamicists and designers. The achievement is made all the more impressive due to the fact that the concept's performance-car design brief demanded wide tires, apertures for cooling air, and optimal downforce.

There are a number of individual features that contribute to the XL Sport's arrow-like performance, in addition to the uncompromising styling. These include special vanes that direct the air at the front into specific channels, wheelarch vents, an optimized underbody, lift-reducing air ducts in the hood, an extendable rear spoiler (powered by the same unit as in the Lamborghini Aventador), and adaptive air vents incorporated in the rear hatch.

The world's most powerful two-cylinder engine. The Ducati 1199 Superleggera's V-Twin engine was slightly modified for use in the XL Sport, but is basically the same as the motorcycle’s. Thanks to its tough, lightweight titanium connecting rods, the 1199 cc double-overhead-camshaft engine can rev up to 11,000 rpm. The Superquadro's high speeds are made possible by its extreme bore/stroke ratio of 112 mm by 60.8 mm and the exceptionally short crankshaft stroke associated with it.

In addition, the two four-valve cylinders, which are arranged at an angle of 90 degrees to each other, feature desmodromic valve control (positive valve closure) that is typical of the high-revving Ducati engines and requires the finest of precision engineering to ensure optimum valve clearance. Other features of the world's most powerful two-cylinder engine are the use of magnesium-alloy for the clutch, cylinder head, and oil pan covers, the two throttle valve discs, and the two fuel injectors per cylinder. Last but by no means least, the XL Sport has a newly developed step-down transmission to reduce engine speeds by a factor of 1.86. Torque from the V-Twin engine (99 pound-feet) is transmitted to the rear axle via a seven-speed DSG® dual-clutch automatic transmission. From a standing start, the XL Sport takes 5.7 seconds to reach 62 mph.

Racing chassis. The significantly redesigned chassis, high-revving engine, and aerodynamic performance firmly plant the XL Sport in the racing realm. The chassis incorporates high-strength steel subframes which house upper and lower control arms at the front with pullrod actuation for the dampers, while the control arms at the back have pushrods—similar to the layout for a racing car. The forged magnesium-alloy wheels, which save 53 pounds compared to aluminum-alloy rims, are fitted with 205/40 R18 front and 265/35 R18 rear high-performance tires. The XL Sport has a powerful ceramic brake disc setup.

CFRP body. Because the XL Sport is a sister model to the XL1, it shares the same basic design. Like the XL1, the central monocoque and most of the body panels are manufactured in carbonfiber-reinforced polymer (CFRP) using the RTM (Resin Transfer Molding) process. The monocoque features slightly offset seats for the driver and passenger.

The wing doors of the XL1 and XL Sport are reminiscent of a high-end sports car’s. They are hinged at two points: low on the A-pillars and just above the windshield in the roof frame, so they swivel upwards and slightly forwards as well. The doors also extend far into the roof, giving an exceptionally large amount of entry and exit space. In order to keep the weight as low as possible, the windows are made from polycarbonate and are fixed in place: just a segment of the lower area of the side windows can be opened.

Compelling proportions. Despite sharing its underlying design with the XL1, the XL Sport has a look of its own. The reason for this is that the XL1 was designed for ultimate fuel efficiency, whereas the XL Sport’s design brief included uncompromising driving dynamics. The XL Sport is longer and wider than the XL1 because of the need for additional downforce on a 168-mph car and because of the packaging requirements of the chassis and powertrain. The XL Sport showcased in Paris is 168.9 inches long (versus 153.1 in for the XL1), 72.7 in wide (65.5 in), and 45.4 in mm high (45.4 in). The wheelbase has also been increased to 95.4 in, up from : 87.6 in.

Design concept. As outlined above, the concept car builds on the dynamic and expressive design of the XL1. The surfaces have an even more muscular appearance as they extend over the significantly broader fenders and the large wheels.

The XL Sport’s broad front section is marked out by dual LED headlights and the XL1’s signature LED daytime running lights. The XL Sport features air intakes on either side of the headlights for the vanes which feed the air around the car's front end. In common with the XL1, the front section of the XL Sport does not have a conventional radiator grille, yet it retains the current Volkswagen design DNA, with horizontal lines dominating this area. The cooling air supply for the Ducati engine is via vents in the rear fenders.

Whereas the XL1 is at its widest at the front and tapers towards the rear, the XL Sport is just as wide at the back as at the front. From above, the shape is that of a classic racing car, with a waisted cockpit area. Air intakes and outlets at the A- and B-posts ensure optimal air flow and cooling for the drive unit. Like the XL1, there are no conventional door mirrors: instead, they are replaced by e-Mirrors, small streamlined cameras integrated in the fenders that send images of the surroundings behind the car to two displays inside the vehicle. In front of the rear wheelarches, the 'Motore Ducati' lettering refers to the 1199 Superleggera engine in the rear.

At the rear, the new XL Sport has four specific eye catching features. First, the extremely wide, flat rear has distinctive “shoulders” above the wheels and an extendable rear spoiler that occupies almost the full width. Second, as with the XL1, there is a coupe-shaped roofline without a rear windshield. The rear hatch that merges into the roofline conceals the Ducati engine, the seven-speed DSG transmission and 3.8 cubic feet of luggage space, and incorporates five louvers that open automatically to cool the drive unit. Third, the iconic red LED ribbon follows the shape of the rear section and is framed at the sides by another, vertical, LED element which serves to emphasize the XL Sport’s width. Fourth, there is a black diffuser that merges almost seamlessly into the completely enclosed underbody and is finished at each side with a chrome exhaust tip.

Interior design. The interior of the XL Sport is based on the XL1’s, but has been modified and individualized to conform with the change in the vehicle's mission. For example, the XL Sport boasts a digital instrument cluster that includes a lap timer and oil pressure display. A carbonfiber cowl extends across the top of the instrument cluster to completely eliminate reflections. The XL Sport's steering wheel has decorative red stitching and has been equipped with aluminum-alloy shift paddles to facilitate ultra-quick gear shifts. There are further classy details to add a sporty touch, with anodized aluminum accents around the air vents, the climate control fascia and the DSG shift gate. The seat belts are red, picking up on the theme of the contrasting red stitching on the steering wheel.
