    Audi Brings quattro Back to the Race Track with New R18 e-tron quattro

    Ingolstadt/Munich – Motor sport is used yet again by AUDI AG to pioneer new technology: the brand with the four ring’s new Le Mans race car is the world’s first LMP1 car to combine a highly-efficient TDI with a hybrid system. quattro drive also celebrates its comeback to the race track with the prototype – in a entirely new form.

    Audi R18 e-tron quattro is the name of the new Le Mans prototype that makes its race debut on May 5 in the 6-hour race at Spa-Francorchamps (Belgium) and fights for overall victory at the famous 24 Hours of Le Mans (France) on June 16/17. Audi unites two technologies in a fascinating way to create a new type of drive, which is also already being tested for future use in production cars: e-tron quattro.

    Hiding behind this description is the next generation four-wheel drive with which Audi combines the advantages of the proven quattro drive with the potential of electromobility. To this end one vehicle axle is powered conventionally, the second by electric motors.

    "Audi has always consciously selected championships and categories in racing that have a close relationship to production and therefore have technical relevance for the Audi customers,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich, who personally drove the new Audi R18 e-tron quattro onto the stage on Wednesday evening during its world premiere in the Audi Training Center at Munich airport – electrically and almost silent. "quattro, TFSI and TDI are three excellent examples of how motorsport has stimulated production development. A similar tendency is apparent with the e-tron quattro: we test a completely new technology on the race track before it’s introduced to the Audi production line.”

    On the Audi R18 e-tron quattro kinetic energy is recovered on the front axle during the braking phase. It is fed as electric into a flywheel accumulator before being retrieved under acceleration again above a speed of 120 km/h. During this procedure only the front axle is integrated. The V6 TDI power plant producing 375 kW (510 hp) continues to transmit its power to the rear wheels. Both systems complement each other to create the new drive principle e-tron quattro.

    Can we expect similar technology in road cars?

    I'm surprised no other replies, this is very significant! The World's first diesel hybrid in Motorsports, let alone AWD diesel hybrid! And at Le Mans! Quattro is back in Motorsports!

    Audi won Sebring today quite easily with last year's R18. Nevertheless I suspect the team isn't too happy about not running as sharp as they would want to with 2 of the 3 R18s having some mechanical issues.
