Hybrid crosses finish line first at Le Mans

In a historical finish at the 80th running of the famous Le Mans 24 Hours, victory has gone to a hybrid vehicle: the Audi R18 e-tron Quattro.

Not only that, but the Audi R18 e-tron Quattro managed to come in first, second, third and fifth. All four Audi R18 cars had the chance to clinch what amounted to the brand’s eleventh Le Mans victory in total. After 378 laps, last year’s winners Marcel Fässler, André Lotterer and Benoît Tréluyer at the wheel of the Audi R18 e-tron quattro designated as car number “1” were again the front runners, according to information supplied by Audi.

Dindo Capello, Tom Kristensen and Allan McNish as the runners-up caused the all-wheel drive of the future in which the conventional drive system is combined with an electrically driven axle to record a one-two result. Audi is already testing this technology in which the drive shaft is replaced by electric cables for use in production vehicles.

Le Mans rookie Marco Bonanomi, Oliver Jarvis and Mike Rockenfeller in the best conventionally powered Audi R18 ultra completed the fourth one-two-three victory for Audi at the Le Mans 24 Hours after 2000, 2002 and 2010. Romain Dumas, Loïc Duval and Marc Gené at the wheel of the second R18 ultra finished in fifth place.

Operating at the rear of all four Audi R18 cars was the latest evolution of the compact V6 TDI engine with VTG mono turbocharger that was used at Le Mans for the first time in 2011. The new ultra-light transmission with a carbon fiber housing – a novelty in a Le Mans sports car – held up to the Le Mans endurance test covering a distance of more than 3200 miles in all four vehicles without any problems as well.

“By achieving this further success at the world’s most important endurance race our engineers demonstrated their high technological expertise in a particularly impressive way,” said Rupert Stadler, chairman of the Board of Management of AUDI AG, who watched the race on location. “With the e-tron quattro in combination with ultra lightweight design, we put a completely new technology on the grid and immediately won with it – this cannot be taken for granted by any means, particularly here at Le Mans. This weekend again showed the type of things that can happen in this race and how important perfect preparation is.”

The two Audi R18 e-tron quattro cars embody these two technologies in a particularly extreme form – and they were the protagonists at the 80th edition of the endurance classic right from the beginning. They only had to relinquish the leading position to one of the two Toyota hybrid vehicles once for a few laps on Saturday night.

After the early retirements of their fiercest rivals the two R18 e-tron quattro cars fought a thrilling duel for victory throughout the night until noon on Sunday during which the lead changed several times and the two diesel hybrid sports cars were often separated by just a few seconds.

An accident by Allan McNish in the fast Porsche corners less than three hours before the finish caused the preliminary decision. Audi Sport Team Joest managed to repair the heavy damage at the front of the R18 e-tron quattro in record time and to thus save second place. In the early phase, car number “2” had lost nearly a lap after a massive piece of rubber pick-up had gotten stuck in the area of the rear suspension.

The winning car with chassis number R18-208H nicknamed “Electra” was not spared from incidents either. Marcel Fässler touched the track barrier twice on Saturday morning: the first time after spinning at high speed and the second time when he had to evade a GT vehicle that was standing sideways in the Mulsanne corner. Benoît Tréluyer, who was suffering from a severe cold which he had caught on Friday while participating in the drivers’ parade in the rain in the center of Le Mans, spun once at the entrance to the pit lane.

The third-placed Audi R18 ultra – car number “4” – lost a lap right at the beginning of the race due to a check of the rear suspension. On late Sunday morning a gear got stuck twice which the driver was able to correct each time by switching the ignition on and off. Afterward the R18 was running perfectly again and allowed Marco Bonanomi and Oliver Jarvis to clinch the first podium place at Le Mans together with Mike Rockenfeller, who returned to the podium a year after his serious accident.

Two nearly identical slips caused the Audi R18 ultra #3 in which Loïc Duval set the fastest lap of the race to lose its chance for victory. On Saturday night, Romain Dumas in the first chicane while lapping a GT vehicle hit the dirty part of the track and slid against the track barrier. The same mishap occurred to Marc Gené on Sunday noon. In both cases, Audi Sport Team Joest managed to repair the R18 in an extremely short period of time. In total, though, twelve laps were lost.
