Audi engineering has a history of bringing revolutionary pieces of technology to Le Mans victory lane. Late version of the Audi R8 prototype was the first race car to run gasoline direct injection and the R10 was the first diesel powered entry of the 24-hour race to claim a win at the Circuit de la Sarthe. Creating their first diesel/electric hybrid prototype race car, Audi entered the 2012 event eager to make the R18 e-tron quattro the vessel to make their latest conquest of Le Mans. After a full day of continuous racing in France, Audi has now become the first auto manufacturer to win with a hybrid race machine. Combining the TDI engine with an electric powertrain, the Audi R18 e-tron quattro launched to the 2012 24 Hours of Le Mans pole with such a long distance needed to be traveled to achieve greatness.
Winning the LMP1 category as well as the overall 24 Hours of Le Mans, the #1 Audi R18 e-tron quattro completed 378 or 3,201.3 miles from Saturday to Sunday for the 11th win for Audi. Piloted by the 2011 race’s winning driver combination of Marcel Fässler, André Lotterer and Benoit Tréluyer, the Audi R18 e-tron quattro prototype led an effort where the Audi Sport Team Joest took the top three positions.
The race for the Audi Sport Team Joest squad was not without challenges. In the first hour of the 24-hour race, a tire puncture brought the #3 Audi R18 Ultra to pit stop for an unscheduled service while the #4 car was brought in with concern for the rear suspension system. On hour three, the #2 Audi R18 e-tron quattro lost a lap to the leading #1 car when a large collection of tire rubber and debris needed to be extracted from the underneath portions of the prototype sports car.
Hour 5, the Audi mechanics were sent into battle to repair the #3 R18 Ultra car after driver Romain Dumas skidded off track. Running third at that point in the event, Dumas managed to drive his severely damaged Audi prototype race car back to the garage area. After roughly 35 minutes of repairs, the #3 Audi R18 Ultra was returned to the Circuit de la Sarthe racetrack in the hands of driver Marc Gene.
The #2 Audi R18 e-tron quattro prototype race car effort in attempting to claim the 2012 Le Mans 24-hour race went south with less than 3 hours remaining in the event. After a race-long battle as the #2 car driven by the collective talents of Dindo Capello, Tom Kristensen and Allan McNish fought with the #1 Audi R18 e-tron quattro teammate, a collision with the retaining barrier. While the #2 race car required substantial repairs, the Audi Sport Team Joest mechanics returned the R18 e-tron quattro to competition for a 2nd place finish.
The non-hybrid Audi R18 Ultra race car #4 vehicle finished 3 laps behind the winning R18 e-tron quattro. Marco Bonanomi, Oliver Jarvis and Mike Rockenfeller drove the #4 machine that allowed the Audi Sport Team Joest squad the ability to own the LMP1 podium. The fourth and final Audi R18 prototype vehicle completing the 2012 24 Hours of Le Mans finished 5th overall. The #3 Audi R18 Ultra shared by Romain Dumas, Loic Duval and Marc Gené finished their eventful 24-hour effort with a Lola-Toyota fielded by Rebellion Racing preventing a top-four sweep of the overall results at Le Mans
Relishing the German automakers latest success at Le Mans, Head of Audi Motorsport Dr. Wolfgang Ullrich said, “It’s a great result that Audi is now the first brand to have achieved victory with a hybrid vehicle – and right on the first run, as before with the two other technologies, and – what’s more – with both R18 e-tron quattro cars on the two top spots.” Competing in the 2012 FIA World Endurance Championship, the Audi Sport Team Joest squad will have a full two months to savour the Le Mans win until the 6 Hours of Silverstone.

First competing in the 24 Hours of Le Mans race in 1999, Audi’s prototype effort has entered into almost every race since as a dominating force. In a quest for a 10th all-day event win at the 8.469-mile Circuit de la Sarthe for the German luxury car brand, the Audi Sport Team Joest squad is launching a 4-car attack on the 2012 round of the ultimate endurance event. With two Audi R18 Ultra sports cars and two brand new Audi R18 e-tron quattro vehicles, this year’s raid for the sports car race will see some real innovations that could have implications on production car technology.
Carbon Fiber Construction
Like many modern racing car vehicles, the Audi R18 Ultra and While the use of lightweight composite materials is a common theme in motorsports through the past 20 years, attempts to reduce weight with present road cars has been the objective of many auto companies. As a follow-up to the company’s widespread deployment of aluminum in the construction of production cars, Audi has already expressed future Audi R8 supercars will utilize an extensive use of carbon fiber components.
e-tron Electric Powertrain
Christened at May’s Six Hours of Spa-Francorchamps World Endurance Championship race in Belgium, the Audi R18 e-tron quattro brought the future of sports car racing to the present. A turbo diesel/electric hybrid powered prototype machine, the R18 e-tron quattro is an inventive concept for employing the advanced powertrain. While the conventional 3.7 liter V-6, mid-mounted engine provides the main power of the R18 e-tron quattro, a flywheel accumulator is channelled with the front axle assembly.
The unique all-wheel drive Audi R18 e-tron Quattro’s first outing on the Spa Francorchamps circuit was promising. Winning pole, the #1 car Audi R18 e-tron quattro was strong through the first event but lost the race due a reported brake vibration issue. Within a top-4 victory in the LMP1 class in Belgium for Audi, the R18 e-tron quattro occupied the 2nd and 4th place spots. The 24 Hours of Le Mans is the second test for the e-tron quattro technology on the Audi R18 for which the German carmakers is eager to see cross the line first.
Audi has pressed the e-tron name into the creation of many auto show design studies with the intent on bringing the electrified technology to the production line.
VTG Turbocharger Technology
Both the Audi R18 ultra and Audi R18 e-tron quattro will be primarily powered by a turbocharged 3.7 liter V-6 TDI engine employing the German company’s cutting edge engineering expertise. Called the Audi’s VTG (Variable turbine geometry) technology, the exhaust gas charge is fed through the turbocharger system can be augmented to provide peak efficiency throughout the power range.
Traditionally, a turbocharger turbine is designed as a compromise in a single unit configuration. Twin-turbocharged engines were developed to increase the flexibility through offering low-end as well as high-end power. Through the VTG system, the Audi R18 prototype will be free from any major turbo lag throughout every corner of the Le Mans circuit.
While Porsches are long been utilizing a variable geometry turbocharger unit, the Audi R18 prototypes will be the first time such technology has been mated with a high-performance TDI race engine.
Digital Rear-View Mirror
The sensitive aerodynamic and mechanical nature of closed cockpit race cars have left drivers suffering from impaired visibility. While competing in the fastest LMP1 class during the 24 Hours of Le Mans where much of their traffic will be approaching from in front, the Audi R18’s rear vision is also pivotal when a teammate or other LMP1 competitor may creep up on a race machine. A day-long race that could be ended with one false move, Audi Sport proficient worked to find a way to improve their R18 prototype pilots’ rear vision without altering the perfected shape of the sports car.
Debuting at the 2012 24 Hours of Le Mans event, a digital rear-view mirror could be a useful tool for capturing the top prize in the French event. Using AMOLED (active-matrix organic light-emitting diode) display technology, the digital reverse view is a multi-colour image fed from a small camera mounted behind the R18 prototype’s roof antenna. The digital rear-view mirror system is a significant advance of the back-up systems created as part of Audi’s active safety available in their road cars.

Searching for their 10th victory, the Audi prototype program has placed every major iteration of their race purpose-built sports cars in the Sebring International Raceway winner’s circle since 2000. The Audi R8 prototype race car, as well as the R10 TDI and R15 TDI are celebrated race vehicles that began their piece of a motorsport dynasty with an inaugural victory at Sebring. Bringing 2011-spec Audi R15 TDI Plus race cars to the Mobil 1 Twelve of Sebring Fueled by Fresh from Florida event last year, the Audi R18 TDI closed cockpit prototype car would break an 11-year trend by winning the 24 Hours of Le Mans first. For the 2012 American Le Mans Series first race and the debut event for the FIA World Endurance Championship (WEC), Audi Sport Team Joest’s three-car R18 team needed to claim the car’s elusive Sebring race.
Without the challenge from the Peugeot 908 sports car that won the previous two Sebring events, the Audi Sport Team Joest team came to the race track carrying a war chest of experience and equipment trumping other prototype class contenders. In Friday qualifying for the half-day Saturday race, the Audi R18 TDI race cars stormed around the 3.7-mile, 17-turn road course claiming the top three starting positions with little opposition. Taking the pole among the three-care Audi R15 group was the #1 vehicle that flew around the Sebring International Raceway with a 1-minute, 45.820-second lap time.
The Audi R18 TDI was almost perfect in its debut at the Mobil 1 Twelve Hours of Sebring event on Saturday. The #1 Audi R18 TDI, handled by the driving team of Andre Lotterer, Benoit Treluyer and Marcel Fassler, parlayed their Friday speed into Saturday race pace. When the #1 car was not leading the race early, one of the three team cars for Audi Sport Team Joest held the top race track position during the first four hours.
In the fourth hour, the harmonious rhythm of the three-car Audi R18 TDI squad would be impacted by an issue with the lead vehicle. Losing the lead first when a pit stop netted a stop-and-go penalty from the race stewards, the #1 Audi R18 TDI race car would crawl back to pit lane more than an hour later. A faulty electrical shifting unit on the gearbox would wind up taking the #1 car to the service area behind the pit wall. Costing the #1 Audi R18 17 laps, the car containing the 2011 24 Hours of Le Mans-winning driving trio returned to competition to finish fifth in the LMP1 category among the WEC registered vehicles.
Taking over from where the #1 car left off in the Mobil 1 Twelve Hours of Sebring, the #2 car piloted by the proven driving combination of Allan McNish, Tom Kristensen and Dindo Capello went on the mission of with the R18 TDI prototype sports car. As day turned to night and the clock for the endurance race ticked down to zero, the #2 Audi Sport Team Joest R18 TDI won the 2012 Mobil 1 Twelve Hours of Sebring by four laps over their #3 team car. “It was consistently fast and made it possible for us to be in contention from the beginning to the end.” said Allan McNish who celebrated his fourth overall win in the Sebring 12-hour race. Winning their first Sebring event since 2009, the #2 drive consisted of the same trio of drivers that brought an Audi R10 across the line on that occasion.
Despite the fact victory seemed easy for the #2 car squad, the winning drivers all combated challenges during the 12 hours of racing. “The car was running well but traffic was a real challenge and the temperatures around noon, when I was sitting in the cockpit for a long time, were pretty high.” said Tom Kristensen adding, “It was tough clinching victory here.” Technical Director for Audi Sport Team Joest added to Kristensen’s acknowledgment saying, “That was a pretty strenuous race. And our rivals were really close on our heels. They were a tiny bit slower than we but in the caution period they wouldn’t ease up on us. They only started having problems in the end. Those were eleven hours of hard work for us. Well done to Dindo (Capello), Tom (Kristensen) and Allan (McNish). It was a superb drive.” The triumph of the Audi squad against the 64-car field at the 2012 Mobil 1 Twelve Hours of Sebring comes as another moment the German-based team conquered with superior technology, engineering, mechanics and drivers.
Attending the first race for the World Endurance Championship, FIA President Jean Todt was witness to the Audi Sport Team Joest operations at Sebring as they flew to sports car victory in 2012. With many dignitaries present, Audi captured the Mobil 1 Twelve Hours of Sebring taking the overall victory as well as the first win for a prototype under the WEC body. Proud of the work of the whole racing operation, Head of Audi Motorsports Dr. Wolfgang Ullrich commented, “Obviously, it’s nice that after the tenth pole position for Audi at Sebring we managed to achieve the tenth victory as well. For us, it was a great start into the season and into the new FIA World Endurance Championship.”
The next FIA World Championship race for the Audi Sport Team Joest organization is the 6 Hours of Spa-Francorchamps on May 6th. This Belgium round of the 2012 series will feature the competitive debut of the diesel/electric Audi R18 e-tron quattro ahead of the 24 Hour of Le Mans event.
This weekend at Sebring International Raceway, the Audi Sport Team Joest prototype organization prepares for the start of the 2012 sports car racing season. Since entering the sports car prototype arena in 1999, Audi’s motorsport efforts have pushed the four-ring badge to the top of track competition while their street cars captured accolades with customers.
With worldwide sales recorded at a 625,807 total in 1999, Audi AG scored 1,303,650 in vehicle unit sales across the planet in 2011 as the German luxury car brand has risen to a serious force in automotive production. While some debate the impact of motorsports on the street vehicles, Audi’s loyal attention to the high-priced sports car competition has provided a better-than-average case proving the benefits of factory support for auto racing. For 2012, the sports car racing efforts in prototype racing Audi Sport Team Joest will present several changes as they will attempt victory on the race track as well as win customers to new, production car-related technology.
As the Audi R18 TDI will take the green flag for the 2012 Mobil 1 Twelve Hours of Sebring, the Team Joest-fielded vehicles will be part of the newly formed FIA World Endurance Championship (WEC). Head of Audi Motorsport Dr. Wolfgang Ullrich committed “It’ll be a grand and no doubt thrilling inaugural event of the new WEC. The entire fields of the WEC and the American Le Mans Series will be competing together. “ The 2012 WEC represents collection of great, modern sports car races assembling on the globe’s most prestigious race circuits. Included in the high profile first season for WEC will debut at Sebring International Raceway before moving onto the Spa Francorchamps road course and famous Circuit de la Sarthe for the 24 Hours of Le Mans. Audi Sport is committed to run every round with their R18 TDI prototypes throughout the inaugural eight-round competition.
Much of the pre-season excitement centered on the Audi prototype sports car program has been centered on the gasoline/electric hybrid version of the R18. Scheduled to run for the first time at the Belgium event in May, the Audi R18 e-tron quattro combines the mid-engine 3.7 liter V-6 TDI engine with an electric motor that will drive the front wheels. With rear wheels still being spun conventionally through TDI powerplant, the new prototype will bring a unique take on Audi’s much-touted quattro all-wheel drive. When Audi Sport Team Joest runs the 24 hours of Le Mans in mid-June, the plan is to run two hybrid cars within a four-car effort. For the Sebring race, Audi has prepared three non-hybrid R18 TDI prototype sports cars.
For the 12-hour event at Sebring, car #1 for Audi Sport Team Joest will feature the teaming of Marcel Fässler, André Lotterer and Benoît Tréluyer who won the 24 Hours of Le Mans for the team last year. In the #2 Audi R18 TDI, the accomplished group of Dindo Capello, Tom Kristensen and Allan McNish will attempt to rekindle the magic they used to collectively win the 2009 Mobil 1 Twelve Hours of Sebring. Sharing the #3 car, Timo Bernhard, Romain Dumas and Loïc Duval will round out the highly talented 2012 driver line-up for Audi Sport Team Joest.
Audi Sport Team Joest will be seeking their 10th victory in the 12-hour race. From 2000 to 2007, Audi had affirmative possession of the Mobil 1 Twelve Hours of Sebring overall honours with the Audi R8 and R10 prototype race cars. Interrupted for claiming victory by a pair of Porsche RS Spyders in 2008, Audi did succeed in maintaining its streak of LMP1 class victory at the Sebring International Raceway for a total of nine consecutive races. Stretching the automaker’s records with a ninth overall Sebring race win in 2009, the Peugeot 908 has presided as the top prototype runner for the famous sports car event. With Peugeot opting out of the 2012 edition of the Mobil1 Twelve Hours of Sebring, the Audi R18 is heavily favoured for victory late Saturday night.
With preparations for the 60th running of the Twelve Hours of Sebring Fueled by Fresh from Florida ongoing this week, the clock for the half-day endurance race starts March 17th at 10:15 AM Eastern time.

An annual event where the best in sports car racing sprint around the Road Atlanta circuit for 1,000 miles or 10-hours (whichever comes first), the Petit Le Mans has become a final event in the sports car racing season. One of many sports car races Audi has won on a multitude of occasions since 2000, the Audi Sport Team Joest race organization will be wearing silver into combat for the first time with their 24 Hours of Le Mans winning R18 TDI prototype sports car. While tested at the Sebring International Raceway just days after the Mobil 12 hour race, the Audi R18 TDI prototype sports car will make its competitive debut in the North America at the 2011 Petit Le Mans in Road Atlanta.
Built to new safety and performance rules set out by the ACO (the French sanctioning body that oversees many sports car events including the 24 Hour of Le Mans race), the Audi R18 TDI is another evolution on the competitive ladder the premium carmaker. Powered by a smaller V-6 engine through an electronic gearbox, the R18 prototype sports car has better weight balance than the previous Audi R15 Plus. The biggest change to the Audi racing machine was the incorporation of a roof over the driver. A closed cockpit prototype, the R18 became the first such vehicle since the early Audi R8C that run last in 1999.
Long respected as a showcase where the best creations of auto manufacturers competed on speed and endurance, sports car racing is once again relevant as a test bed for modern automotive technology. In the case of Audi, their prototype sports car program aided in the refinement of several items currently utilized in production car. Their Audi R8 prototype won the Le Mans 24-hour race thanks to the FSI gasoline direct injection technology allowing team drivers to remain on track longer. Since the introduction of the Audi R10 in 2006, the German automaker advocates their clean diesel technology discovering an unfair advantage over gasoline-powered race cars. In the Audi R18 TDI, the race vehicle is the showcase for full LED headlights recently introduced in production vehicles including the Audi A8 sedan. Introduced as low-beam illumination on the Audi R15 TDI sports car, the LED lighting technology is fine-tuned for the R18 prototype.
Making its debut at the 2011 Petit Le Mans, this race is part of the 6-race run for the Intercontinental Le Mans Cup. An award that the ACO established in 2010, this is a modern initiate to crown a global honour. Leaving the 6-Hours of Silverstone, the Peugeot squad’s 908 prototype has propelled the French team to a 7-point lead over Audi Sport Team Joest. Having won the Petit Le Mans 9 times in the LMP (Le Mans Prototype) class, the Audi R18 TDI will have to out muscle the Peugeot who has won the previous two Road Atlanta events.
On October 1st, Audi Sport Team Joest will bring a two-car contingent with three drivers per Audi R15 TDI race machine. In car #1, Timo Bernard, Romain Dumas and Marcel Fassler combining for 4 overall wins at Road Atlanta. The #2 Audi R18 TDI will be helmed by an experienced trio of Tom Kristensen, Allan McNish and Dindo Capello.
