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-wheeldrive 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.

My variable blades went wrong in my A3 after 62k miles, felt like an SDI after that until fixed.

Been interesting to see if the hybrid stuff can get them any more laps between refuelling.

Le Mans change to fuel regs... http://www.lemans.or...tions_4130.html

Change of fuel Regs.

Regulation Changes after Spa. The original 2011 regulations were adjusted after Spa this year when the ACO had accurate ‘Race Data’ to work from. They had always planned to review the regulations after two races and they took the decision to adjust the performance between some of the cars in the same category. They took into account power, torque, aerodynamics, cornering speeds, pit stop times, fuel consumption and so on.

The decision was made to change the diameter of the refuelling hose nozzles. The petrol engined cars will be enlarged by 10mm and the diesel nozzles will be reduced by 3mm.

Next they looked at finely tuning the air restrictors for certain cars to equalise performance. If the restrictors could not be changed then additional weight would be added to the car.

So what will the impact of these seemingly quite small changes be? Looking at the fuel nozzles first . Firstly changing such a simple component is simple and inexpensive. The maximum quantity of fuel on board a diesel is 65 litres for the diesels and 75 litres for the petrol-engined cars. The number of laps between refuelling stops should now be the same for both petrol and diesel engines. But the diesels will be spending more time at their pits because the fuel flow will be slower. Overall, these adjustments will be more noticeable on the distance covered at the finish, rather than the seconds gained over a lap as we’re acting mainly on the pit stop times. It could translate into a gain of four or five laps during the Le Mans 24 Hours.”
