Audi has revealed that its 2014 World Endurance Championship challenger incorporates a Formula 1-style second energy-recovery system.
Thermal energy recovered from the exhaust gases of the new Audi R18 e-tron quattro's turbodiesel V6 engine will feed the same flywheel storage system that takes the kinetic energy retrieved from the front axle under braking.
It is understood that the technology is in line with the MGU-H (motor generator unit - heat) systems that will be used in Formula 1 from next season and will allow Audi to feed energy back to the turbocharger to combat drag.
An Audi press statement highlighting key technical details of the latest R18 e-tron quattro explained the system.
"The turbocharger of the internal combustion engine is linked to an electrical machine, which makes it possible to convert the thermal energy of the exhaust gas flow into electric energy, - for instance, when the boost pressure limit has been reached," it read.
"When the car accelerates, the stored energy can either flow back to the MGU at the front axle or to the innovative electric turbocharger, depending on the operating strategy."
Audi is referring to the two technologies as Energy Recovery System - Kinetic and ERS-Heat.
Porsche has also stated that its second hybrid system allowed under the new regulations also harness energy from exhaust gases.
Toyota will use front and rear kinetic energy retrieval systems.
Audi has also revealed that it will be unable to run the blown diffuser of this year's R18 courtesy of the new regulations.
Audi Sport has "redeveloped every single component" on the new car, the statement said, even though it retains the type number and look of its predecessor.
This follows changes in the chassis rules that reduce the overall width of the LMP1 cars by five percent or 10mm, mandate narrower front tyres and stipulate a larger cockpit area.
The new Audi was conceived during 2012, with the design of the car beginning at the end of the year.
Testing of the new R18 began in secret during the early in the autumn in Europe with Marco Bonanomi driving.
Andre Lotterer, Benoit Treluyer and Marcel Fassler are known to have taken part in this week's Sebring test.

At the world premiere of the new Audi R18 e-tron quattro, Audi unveiled another technical highlight of its new LMP1 sports car in Ingolstadt on Wednesday night. In 2014, the brand with the four rings will be running with laser light for the first time in the Le Mans 24 Hours and in the FIA World Endurance Championship (WEC).
“By using this new lighting technology Audi is setting yet another milestone at Le Mans,” said Dr. Ulrich Hackenberg, Member of the Management Board for Technical Development of AUDI AG, at the official presentation of the new R18 e-tron quattro that took place as part of the Audi Sport Finale. “Laser light will also open up completely new possibilities for our production models in the future. Once more, motorsport at Audi accelerates a new technical development for our customers.”
The innovative laser light, which about 500 guests in attendance at the Audi Sport Finale had the chance to experience live for the first time, complements the main LED headlights of the new Audi R18 e-tron quattro. A blue laser beam backlights a yellow phosphorus crystal lens through which the light beam is then emitted. This new light source provides even more homogenous lighting of the road.
Laser light just one of numerous innovations of the new R18
“The new laser light is just one of numerous technical innovations featured by our new R18,” said Head of Audi Motorsport Dr. Wolfgang Ullrich, who was recognized by Dr. Ulrich Hackenberg on Wednesday night on the occasion of his 20th anniversary at the helm of Audi Sport. “We’re not going to reveal any more than that at this early stage, as in 2014 we’re facing an extremely tough competition and a year full of challenges for Audi Sport.”
As before, the motorsport commitment of AUDI AG in the new season will continue to consist of the three pillars Le Mans prototypes (LMP1), DTM and GT sport. In addition, Audi Sport is preparing for its move into the new Motorsport Competence Center in Neuburg in the summer of 2014. “This is a very important step to ensure that Audi will retain its ability to be successfully active in motorsport at the highest level but, obviously, it also puts an additional strain on our squad,” said Dr. Ullrich.
Three Audi R18 e-tron quattro cars in Le Mans 24 Hours
The FIA World Endurance Championship (WEC) will see Audi Sport Team Joest compete as the title defender in the 2014 season. In all eight races of the 2014 WEC, the World Champions will be running with two Audi R18 e-tron quattro cars. For the season’s pinnacle event at Le Mans on June 14/15, 2014, the fielding of a third R18 is planned. The driver teams will be announced at a later date.

Press release...
Audi began the 2014 WEC season with a spectacular appearance. The new Audi R18 e-tron quattro did not do its initial kilometers at Le Mans on the legendary race track in Western France but in public traffic. Audi factory driver Tom Kristensen, with nine victories under his belt the record holder of the Le Mans 24 Hours, drove the diesel hybrid sports car from the Saint-Julien du Mans cathedral in the city center to the famous race track.
Accompanied by TV cameras and photographers, and featured in a live worldwide broadcast on the internet, Audi’s new LMP1 race car completed the near-ten-kilometer distance through the city in a motorcade, did a lap on the Circuit Bugatti and arrived in front of the race track’s modern Welcome Center amid the applause of the invited international journalists and guests. “I’ve been competing at Le Mans since 1997 but this was absolutely new for me, too, and very exciting,” said Tom Kristensen, who in 2006 had driven the revolutionary Audi R10 TDI on its world premiere – in Paris – in public traffic as well.
Aside from the unusual drive which brought back memories of a Le Mans era from the distant past when the drivers would arrive in their own race cars, Audi surprised the public with a new livery of the Le Mans car. While the body of the new R18 e-tron quattro was still black with red details when the car made its world debut in December, a striking color scheme now catches the eye. The new color scheme of white, silver, red and black stands for fresh, expressive graphics. “The colors are symbolic,” explains Dirk van Braeckel, Design Manager Motorsport and Special Projects at Audi. “Silver emphasizes the past success in racing. As a very quiet color, it provides the base for our livery. White, as the second color, harmonizes well with silver and appears very light. It stands for the hybrid drive. White is used asymmetrically in order to symbolize the complexity of this powertrain technology.” The contours are modeled after the conductive tracks on PCBs, but clearly featured as an abstraction.
The next color is black. It is used for the front and rear wings, as well as on sections of the fenders and sides with highly defined geometric contours. “We opted for matt black, as it nicely contrasts with the gloss white,” says van Braeckel. “Black stands for light-weight design. The black look of the large fin on the engine cover is intended to represent something like a backbone.” A unique red – Audi’s performance color – completes the graphics. Special characteristics include the reflecting surfaces of the elements, Audi’s logos and inscriptions that are exclusively applied to these areas, as well as the pronounced longitudinal orientation of the color in the overall concept. “The reflective livery is particularly impressive at night and provides the spectators with an enhanced experience,” explains van Braeckel. “Due to its longitudinal orientation the graphics express the speed that is so typical for Le Mans. Even the rims include a red segment. Due to the wheel rotation, it achieves a very dynamic effect.”
More cubic capacity for higher efficiency
The Audi R18 e-tron quattro did not only cause a sensation on its drive through Le Mans due to its striking livery. At the beginning of a fundamentally new technological era, Audi published the key technical data of the race car’s powertrain as well. For instance, the cubic capacity of the V6 TDI power plant was increased from 3.7 to four liters in order to further optimize the engine that had already been very efficient. After testing various energy recovery systems, Audi decided to compete in the class of up to two megajoules of recuperation energy at Le Mans. The energy exclusively flows through a motor generator unit (MGU) at the front axle and is stored in a flywheel energy storage system. “We opted for this concept following extensive testing,” says Head of Audi Motorsport Dr. Wolfgang Ullrich. “In our opinion, it provides the optimum balance between efficient energy use, size, weight, energy conversion efficiency, responsiveness, drivability and a favorable operating strategy – combined with durability, which is the basic prerequisite for success at Le Mans.”
On March 28 and 29, the Audi R18 e-tron quattro will be participating in the official test of the FIA World Endurance Championship (WEC) at Le Castellet (France) before World Champions Audi begins its title defense at Silverstone in the UK on April 20.

PR:
Ingolstadt, Germany – Audi is starting the 2015 season with a thoroughly revised R18 e-tron quattro. In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season’s pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class.
A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. “The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used. The rules harbor so much potential that there is room for future developments,” says Jörg Zander, Audi Sport’s new Head of Engineering. “We expect that the technological progress resulting from the fierce competitive pressure exerted by four automobile manufacturers that are now involved will significantly improve lap times this season – while concurrently reducing fuel consumption.”
The new R18 e-tron quattro visually differs clearly from its predecessor even though its basic structure is closely akin to the previous model. The fresh look results from a new way of conducting airflow around and through the front end, in the area of the sidepods and at the rear of the LMP1 prototype. Large air inlets in the front wheel arches reduce aerodynamic drag of the body and have led to an all-new design of the headlights. The lighting units feature Matrix LED technology combined with Audi Laserlight – two innovations that improve active safety in road traffic and that Audi customers can now order for their production models as well.
While Audi has adopted the monocoque – the central safety cell of the race car – from the previous model, the hood with the front wing and wheel arches features a new design. As this body element incorporates the crash structure, Audi performed a new crash test for the 2015 season. Modified airflow through the sidepods with new radiator configurations for cooling the engine and the hybrid system further optimizes aerodynamic drag. The engine cover, which encloses the unit even more tightly and notably tapers off behind the cockpit, contributes to this as well.
This year, Audi is again preparing two body versions for the various tracks on the FIA WEC calendar. In combination with an optimized chassis and in close cooperation with tire partner Michelin, Audi has further improved the performance potential of its sports prototype this way.
Hybrid pioneer Audi is taking the next step in the area of energy recovery as well. The company is the only manufacturer to date to have won the Le Mans 24 Hours with hybrid sports cars. Since 2012, the R18 e-tron quattro has been unbeaten in the French endurance classic. For this year, the engineers have doubled the amount of energy from 2 to 4 megajoules per race lap at Le Mans. During braking, energy is recovered which the system subsequently feeds back to the front axle on acceleration. The electrical machine that performs this task now delivers an output of more than 200 kW (272 hp), which is a significant increase compared to last year. Therefore, Audi has increased the capacity of the energy storage system as well. The encapsulated flywheel energy storage system that sits in the cockpit alongside the driver can store up to 700 kilojoules of energy that it subsequently returns to the electrical machine – which is about 17 percent more than in 2014.
Despite these performance increases Audi has achieved the minimum weight of only 870 kilograms – notably in what is currently the world’s most complex racing category. The improved hybrid output, however, results in a restriction for the internal combustion engine. According to the sporting regulations the fuel-energy amount has to be further reduced if the engineers opt for higher hybrid output. As a result, the R18 e-tron quattro has to make do with 2.5 percent less diesel fuel per lap than in 2014.
Not least for this reason, Audi has further developed the four-liter V6 TDI engine by performing a lot of detailed work to achieve the optimized consumption levels. The most efficient power-plant in the field now delivers 410 kW (558 hp). Due to its optimized consumption the developers have managed to more than compensate for the loss in output resulting from the reduced amount of fuel. As another new rule this year, only five engines per race car may be used during the entire season. The power-plant now delivering even greater fuel efficiency continues a major trend. In 2006, Audi’s TDI engine debuted at Le Mans, followed by eight victories until 2014. While lap times continually improved, fuel consumption decreased by 38 percent during this period.
As a result, the youngest generation of the R18 emphasizes the purpose which motorsport serves at Audi in many fields. Ever since the first Audi quattro was fielded in 1980, the brand has consistently been using circuit racing and rallying for the development of forward-thinking technologies that are subsequently used in production – from quattro four-wheel drive to TFSI gasoline direct injection, to the further development of TDI engines, through to innovations such as Matrix LED light and Audi Laserlight. At the Geneva Motor Show in March, Audi unveiled two other innovations with a reference to motorsport. For the first time, the brand showcased a hybrid model – the Q7 – that combines the e-tron quattro principle with a TDI engine. And the new R8* is the first model featuring the Audi Space Frame as a multi-material construction. In addition to aluminum, the frame includes a component made of carbon fiber reinforced plastics (CFRP), a material that has long become a staple in racing.

As this body element incorporates the crash structure, Audi performed a new crash test for the 2015 season. Modified airflow through the sidepods with new radiator configurations for cooling the engine and the hybrid system further optimizes aerodynamic drag. The engine cover, which encloses the unit even more tightly and notably tapers off behind the cockpit, contributes to this as well.
This year, Audi is again preparing two body versions for the various tracks on the FIA WEC calendar. In combination with an optimized chassis and in close cooperation with tire partner Michelin, Audi has further improved the performance potential of its sports prototype this way.
Hybrid pioneer Audi is taking the next step in the area of energy recovery as well. The company is the only manufacturer to date to have won the Le Mans 24 Hours with hybrid sports cars. Since 2012, the R18 e-tron quattro has been unbeaten in the French endurance classic. For this year, the engineers have doubled the amount of energy from 2 to 4 megajoules per race lap at Le Mans. During braking, energy is recovered which the system subsequently feeds back to the front axle on acceleration. The electrical machine that performs this task now delivers an output of more than 200 kW (272 hp), which is a significant increase compared to last year. Therefore, Audi has increased the capacity of the energy storage system as well. The encapsulated flywheel energy storage system that sits in the cockpit alongside the driver can store up to 700 kilojoules of energy that it subsequently returns to the electrical machine – which is about 17 percent more than in 2014.
Despite these performance increases Audi has achieved the minimum weight of only 870 kilograms – notably in what is currently the world’s most complex racing category. The improved hybrid output, however, results in a restriction for the internal combustion engine. According to the sporting regulations the fuel-energy amount has to be further reduced if the engineers opt for higher hybrid output. As a result, the R18 e-tron quattro has to make do with 2.5 percent less diesel fuel per lap than in 2014.
Not least for this reason, Audi has further developed the four-liter V6 TDI engine by performing a lot of detailed work to achieve the optimized consumption levels. The most efficient power-plant in the field now delivers 410 kW (558 hp). Due to its optimized consumption the developers have managed to more than compensate for the loss in output resulting from the reduced amount of fuel. As another new rule this year, only five engines per race car may be used during the entire season. The power-plant now delivering even greater fuel efficiency continues a major trend. In 2006, Audi’s TDI engine debuted at Le Mans, followed by eight victories until 2014. While lap times continually improved, fuel consumption decreased by 38 percent during this period.
As a result, the youngest generation of the R18 emphasizes the purpose which motorsport serves at Audi in many fields. Ever since the first Audi quattro was fielded in 1980, the brand has consistently been using circuit racing and rallying for the development of forward-thinking technologies that are subsequently used in production – from quattro four-wheel drive to TFSI gasoline direct injection, to the further development of TDI engines, through to innovations such as Matrix LED light and Audi Laserlight. At the Geneva Motor Show in March, Audi unveiled two other innovations with a reference to motorsport. For the first time, the brand showcased a hybrid model – the Q7 – that combines the e-tron quattro principle with a TDI engine. And the new R8* is the first model featuring the Audi Space Frame as a multi-material construction. In addition to aluminum, the frame includes a component made of carbon fiber reinforced plastics (CFRP), a material that has long become a staple in racing.

From here: 2016 Audi R18 LMP1 World Endurance Championship Racer Revealed
This year’s World Endurance Championship has just concluded, with Porsche taking the Constructors’ Championship title and the pilots of the number 17 Porsche 919 Hybrid—Timo Bernhard, Brendon Hartley and Mark Webber—taking the titles in the Drivers’ Championship.
Audi, whose own drivers were just five points behind in the end, is determined to claw its way back to the winner’s circle and has already unveiled its challenger for next season. The new race car, which will once again compete in the premier LMP1 hybrid class of the WEC, is still classified as an R18 but is significantly enhanced compared to last year’s car (Audi’s first R18 was launched in 2011).
Audi says the 2016 R18 is the most powerful and efficient race car it’s ever built. Specific areas of enhancement include the new aerodynamic features, next-generation lightweight technologies and modified hybrid system that relies on lithium-ion batteries for storage of recaptured energy rather than a flywheel-based system. The car’s diesel engine, a turbocharged 4.0-liter V-6, has also been made more efficient.
Full specs will likely be released in the lead up to the Prologue pre-season test early next year. The 2016 WEC will host its first race at the Silverstone Circuit on April 17. Audi has also confirmed that it, together with fellow Volkswagen Group brand Porsche, will each enter just two cars in round three, the 24 Hours of Le Mans, instead of the three cars that have been run recently, in the interest of reducing costs.
“With our new Audi R18, we’re setting a clear signal,” Audi motorsport boss Wolfgang Ullrich said at the reveal. “Audi continues to put the pedal to the metal in motorsport, deliberately relying on TDI—the world’s most successful automotiveefficiency technology—at Le Mans.

Sports car fans will suffer another pang from Audi's surprise exit from the World Endurance Championship following the release of these images of a scale model of what would have been the 2017 version of the company's R18 LMP1 prototype.
Audi's former LMP1 drivers Filipe Albuquerque, Oliver Jarvis and Loic Duval posted images of the model on social media following its appperance at a company holiday banquet where Audi's epic 18-year-run in prototype racing was celebrated. The model hints at aerodynamic tweaks that would have been made for next season, including additional fairing around the front wheels.
