Sharing the same name as the 2013 competition car, the 2014 Audi R18 e-tron quattro is technically a completely different vehicle. Changed through FIA rules and by the ingenuity of Audi, this year’s race car is designed to be safer as well as capable of utilizing a greater amount of electric assisted propulsion. Arriving at Le Mans ahead of the 2014 FIA WEC season even starts, Audi took the new R18 e-tron on a recreational journey on French streets in the hands of legendary driver Tom Kristensen. The initial 10-kilometer trip on public streets involved the media along with numerous spectators who acquired what might be the closest contact general citizens will receive to a running 2014 Audi R18 e-tron quattro. Later, Kristensen piloted the R18 e-tron Quattro for a lap around the Circuit Bugatti (a permanent race course connected to the larger Circuit de la Sarthe). Describing the experience, Tom Kristensen commented, “I’ve been competing at Le Mans since 1997 but this was absolutely new for me, too, and very exciting,”. In 2006, Kristensen was part of a similar promotional drive through the streets of Paris with an Audi R10 TDI prototype.
The true test of the new Audi R18 e-tron quattro comes with the start of the 2014 FIA World Endurance Championship. The WEC season starts with the Silverstone 6 Hours race on April 20th. The 2014 24 Hours of Le Mans is scheduled for June 15th will be the location Audi truly wants their colors to shine.

Winning six of the eight races on the 2013 schedule for the FIA World Endurance Championship, it would be easy to assume the Audi R18 e-tron quattro fielded by Audi Sport Team Joest was a dominant car in the LMP1 category. What does the LMP1 manufacturers’ championship winning mean to Audi? It is time for the German car brand to completely reengineer their race car. With the Toyota TS030 Hybrid proving to be a strong competitor and Porsche’s entrance to the LMP1 category on-course for next year, Audi simply cannot rest on their laurels. Keeping the Audi R18 e-tron quattro name for 2014, the race car appearing on the race track will be a drastically different car from the one that last raced at the Bahrain International Circuit last month.
Conforming to 2014 rule changes made to the World Endurance Championship’s LMP1 category, the new Audi R18 e-tron quattro is safer and more energy efficient than the newly-retired vehicle. The body of the 2014 race car will be 10 centimeters slimmer but will also be 20 millimeters higher than the 2013 R18 e-tron quattro. The increased vehicle height is created for improved cockpit room and contributes with other design changes that improve visibility. A greater level of protection greets the pilot of the new Audi R18 e-tron quattro with a stronger-than-ever carbon fiber reinforced polymer cockpit structure. A narrower underfloor is lined with additional layers of fiber and the prototype sports car’s monocoque is built to handle more severe loads. Crash energy-absorbing zone is built into the R18 e-tron quattro prototype’s rear in order to greater reduce the impact to the driver.
One notable difference for sports car fans observing the Audi R18 e-tron quattro in 2014 is the presence of a front wing. New regulations permit the features as a cost-cutting solution to front diffusers. While gaining in one area, the 2014 LMP1 race car loses an aerodynamic aid at another area. The 2014 rule changes for LMP1 ban the process of using engine exhaust to flow over the rear diffuser. A practice that generated greater downforce, such use of exhaust gas had already been prohibited in Formula 1.
The powerplant of the 2014 Audi R18 e-tron quattro prototype sports car receives some of the most extraordinary improvements. Under the new World Endurance Championship LMP1 class rules, the powerplants of 2014 sports cars will be regulated based on energy consumption. The V-6 TDi engine returns with an electric turbocharger feeding the combustion chambers by converting thermal energy. This concept of electric forced-air induction is exceptionally new and has been up until now largely experimental. The electric turbocharger is aligned with the flywheel energy storage system so it is possible to feed electrical drive system when the TDi’s maximum boost pressure is met. The new Audi R18 e-tron quattro’s hybrid drive system works similar to the original vehicle that ran the past two sports car seasons. Electric drive is focused at the front while direct TDi engine performance is delivered through the rear wheels. Regenerative braking will continue to play a big part in recharging the electric drive storage system of the R18 e-tron quattro in 2014 trim.
Overall, the new Audi R18 e-tron quattro has been lightened by 45 kilograms. Weighing 870 kilograms (1,918 pounds) in total, Audi’s has succeeded applying in their lightweight production car philosophy to their new prototype. Other improvements made to the 2014 Audi R18 e-tron quattro include wheel tethers. Wheel tethers work to reduce the chances of a wheel/tire combination flying away violently from the vehicle in case of a crash. With each tether capable of withstanding a weight force of nine metric tons, two are installed on each wheel to set places on the 2014 race car.
Entering an all-new technological realm with electric turbocharging and other safety refinements, what can race fans expect from the Audi R18 e-tron quattro for 2014? Please keep in mind, Milestones already reached by Audi since 2000 includes the first 24 Hours of Le Mans overall-winning vehicle to be equipped with gasoline direct injection, turbo diesel power as well as a diesel/electric hybrid powertrain.

This past weekend, the crown jewel of Audi’s 2013 racing season was campaigned. Making history last year as the first hybrid race car to win the 24-hour race, the Audi R18 e-tron quattro defended its accomplishment for a second-straight year at the Circuit de la Sarthe. Completing 348 laps worth 4742.89 kilometers around the 4.273-kilometer road course, Tom Kristensen, Allan McNish and Loïc Duval combined efforts to bring the #2 Audi prototype to a 12th win since the 2000 Le Mans race. As a team, Audi Sport Team Joest R18 e-tron quattro race machines claimed the first, third and fifth place positions in the 2013 edition of the French endurance classic.
For some, seeing the Audi Sport Team Joest organization once again celebrating a victory at the 24 Hours of Le Mans was somewhat of a sleeper story. Despite the near magic of constantly winning a daylong endurance race, the competition in most of the Le Mans races contended since 2000 would consist of one Audi racing against another Audi prototype car. Even the company’s press release seemed to be taking the news of their 12th 24 Hours of Le Mans win in 14 runnings in stride. Perhaps what had been most coveted is an adversary to the great name. From 2007 to 2011, Peugeot gave Audi a reason to fear losing to the 908 HDi FAP race car. Losing the 2009 endurance classic to the Peugeot 908, The Audi Sport effort in the prototype category was never as determined as it was in the following year’s event when the R15 plus recaptured begging rights of Le Mans.
As Peugeot withdrew from the prototype category, the top class in sports car racing once again needed a formidable challenger to give the Audi R18 e-tron quattro a run for its money. Fortunate to say, the 2013 edition of the 24 Hours of Le Mans did provide a reason for the TDI diesel/electric hybrid race car to push hard. Last year, a new effort from Japanese auto giant Toyota appeared to have the scope to topple the Audi Sport dominance of sports car racing. Toyota Motorsports entered the 2012 24 Hours of Le Mans race with lots of potential but was ill prepared to compete with their brand-new TS030 Hybrid car. However, as Toyota and Audi met in subsequent WEC sports car races, TS030 Hybrid became a threat to R18 e-tron quattro.
In the 2013 24 Hours of Le Mans, spectators were treated to one of the more contentious prototype battles. Though the lead Audi R18 e-tron quattro finished a lap in front of the Toyota, the fact the Japanese car was able to spoil a podium sweep was stark contrast to a year earlier. Fending off a challenge from a stout Toyota effort, the Audi R18 e-tron quattros were split by the rival race machines that collected second and fourth place overall.
Drivers of the #2 Winning his ninth Le Mans 24-Hour race overall, co-driver of the #2 Audi R18 e-tron quattro Tom Kristensen explained the feat personally. “For me, Le Mans was filled with very personal emotions this time. I’m proud to drive for the world’s best team. This applies to all teammates, all employees in Ingolstadt and Neckarsulm and for Audi Sport Team Joest. They make it possible for us to realize a dream. Now this dream has come true again – winning the fastest and toughest race under the direction of Dr. Wolfgang Ullrich.” said Kristensen. For Kristensen and long-time teammate Allan McNish, the win for Audi Sport Team Joest duo was their first since 2008. In contrast, the winning car’s third driver 31-year old Frenchman Loïc Duval would toast his first overall victory at Le Mans.
The 2013 24 Hours of Le Mans victory was overshadowed by a tragic event occurring only minutes into the race. LMGTE-AM class driver Allan Simonsen crashed a wall hard in his Aston Martin. After the lap three crash, the Danish driver Simonsen was initially reported conscious when emergency crews recovered him from the car. However, a short time after the incident, it was announced that Allan Simonsen had died because of his injuries. A haunting reminder of the dangers of a sport propelling human beings at blazing, a death of race car driver is a time where victories less not important and mortality in taken into account. The Le Mans race continued realizing the loss of a speed-seeking comrade (the first death at the 24 Hours of Le Mans since 1997).
For Audi Sport Team Joest, some drivers and crewmembers may have recalled the death of Michelle Alboreto. In 2001, Alboreto was testing an Audi R8 prototype when a tire failed causing the car to veer into a wall. Michelle Alboreto has been the only driver who died in the Audi prototype effort since it was founded in the late 1990s. Similar to Audi, Aston Martin Racing continued to race after the news of Simonsen. Due to the fatal crash of Allan Simonsen and several other long safety car periods, the 2013 24 Hours of Le Mans overall distance completed was the shortest since 2001.
For the Audi Sport Team Joest organization, the 2013 24 Hours of Le Mans successfully fought to be recognized as the top of the sports car kingdom. However, at the top, it was evermore clear to the team this particular victory celebration would be somewhat muted. Head of Audi Motorsport Dr Wolfgang Ullrich stated, “That was the most difficult race I’ve experienced in my 15 Le Mans years. One reason, no doubt, was having to see a young race driver from Denmark lose his life this weekend. We’re feeling with his family.“ A fellow Danish driver, Tom Kristensen dedicated the win to recently departed Allan Simonsen.

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.

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.
