R18 e-tron quattro diesel hybrid sports car with most fuel-efficient powertrain.
Ingolstadt - Audi has been competing at Le Mans since 1999 in order to achieve sporting success with technological innovations. Never before has an LMP1 race car sporting the four rings been as light, fuel-saving and efficient as the current Audi R18 e-tron quattro. As required by the regulations, its fuel consumption per 100 kilometers has to be up to 30 percent lower than that of the competitors. Despite these tough requirements, Audi is endeavoring to battle for its 13th victory in the Le Mans 24 Hours on June 14 and 15.
Audi has been setting efficiency standards with its ultra technology. Since 2001, TFSI gasoline direct injection helped to considerably reduce fuel consumption at Le Mans, and subsequently in Audis production automobiles as well. Since 2006, Audi caused a sensation with the TDI engine and five victories at Le Mans. Since 2012, the diesel hybrid drive of the R18 e-tron quattro has been unbeaten at La Sarthe. The next major step results from the efficiency regulations in 2014. Fundamentally new rules determine that Audi and its rivals in the battle for overall victory have to economize on fuel up to 30 percent less is available this year, depending on the concept and rating. And this requires a highly efficient race car.
In concrete terms, 138.7 megajoules of fuel energy are available to the new R18 e-tron quattro per lap at Le Mans. This amounts to 6.16 liters less per 100 kilometers than the gasoline engines of the challengers, Toyota and Porsche, are allowed to consume. If the best teams, as last was the case in the 2012 season that saw only brief safety car periods, covered 378 laps, then Audis high-performance TDI engine would have 317.52 liters less fuel available in the course of 24 hours than the gasoline units. This results in an easily understandable comparative situation that every customer is familiar with in normal road traffic: how efficient is a diesel and how efficient a gasoline engine?
The situation at Le Mans is aggravated by the sum of all ratings. A complex set of rules assesses the various technical concepts. Through energy allocations and fuel flow quantities, as well as the pit stop intervals resulting from fuel consumption and fuel tank capacity, the regulations aim to achieve an equivalence of technology.
Last years winners Loïc Duval (F) and Tom Kristensen (DK), who is the Le Mans record holder with nine victories to his credit, are sharing the number 1 R18 e-tron quattro with Lucas di Grassi (BR). Car number 2 is driven by Marcel Fässler/André Lotterer/Benoît Tréluyer (CH/D/F), who decided the iconic endurance race in their favor in 2011 and 2012. At the wheel of car number 3 is the Le Mans rookie Filipe Albuquerque (P). He is sharing the cockpit with Marco Bonanomi (I) and Oliver Jarvis (GB), who have previously been on podium in the 24-hour race.
With that, Audi has a powerful, well-balanced squad that combines a total of 16 Le Mans victories. Head of Audi Motorsport Dr. Wolfgang Ullrich and Chris Reinke, Head of LMP at Audi, can equally rely on their drivers and on Audi Sport Team Joest. Still, Audis 16th run at Le Mans will be more challenging than ever before. On the test day at Le Mans, on June 1, Audi successfully completed its preparations. When the 82nd edition of the Le Mans 24 Hours begins at 15.00 on June 14, Audi, in addition to drawing on its expertise and abilities, will need some racing fortune. Eurosport will be airing full-length coverage of the race. At www.audi-motorsport.com spectators can also watch the race from the cockpit perspective of the R18 e-tron quattro. Various telemetry data are available as well.

Quotes by the officials
Dr. Wolfgang Ullrich (Head of Audi Motorsport): With three manufacturers now competing in the LMP1H category, the level of the event has clearly risen once more. This does not degrade any of the past races, as special challenges arise every year, not always just because of the competition but also because of the race itself. There have been years at Le Mans in which we were successful even though our car wasnt the fastest one. We can recognize the true picture only in the race. We aim to be perfect and to battle for victory with speed and reliability.
Chris Reinke (Head of LMP): The preparation time was very long, considering that the new regulations were created over the period of several years and that the concept design and development stage was followed by a long testing phase and the first two races of the season. That was a very complex task. Im convinced that we developed a good race car. Now were looking forward to the direct comparison of all manufacturers in the race.
Ralf Jüttner (Team Director Audi Sport Team Joest): Le Mans 2014 will be one of the races in which we cant afford to make any mistakes. The regulations do not want to see a race car thats superior to the competitors, for instance in terms of lap times. But thats not the only thing. Our aim is to give the drivers a car that allows them to drive three- or four-hour stints as closely as possible to the limit without getting tired. This aspect will decide the race. So, as a team, we need to work out a good set-up. Weve been in comparable situations before and managed to do a zero-defect job then as well. We want to try and do that again this time.
