Audi's newly revealed R18 e-tron quattro race car is designed to win the 2012 Le Mans 24 Hour Race. Whatsmore, the turbodiesel, electric flywheel hybrid, all-wheel drive prototype will ensure the 2012 race will be a battle of the hybrids (against Toyota's new TS030 ultracapacitor hybrid race car), and a fascinating study of new technologies under race conditions. The car uses electric motors to add 75 kW (102 bhp) of power to each front wheel, and a 375 kW (510 bhp) V6 TDI engine powers the rear wheels. The Williams Hybrid Power electric flywheel hybrid captures energy similarly to the unit Porsche used to such great effect in its GT3 R Hybrid last year with the rear axle powered conventionally, and the front wheels by electric motors. Audi calls it "the electrification of the drive" and it will be a story worth following as battle begins on the racetrack.
