Audi R18 e-tron ultra: AWD Hybrid Diesel Headed for Le Mans


I previously posted about Audi’s hybrid prototype sports cars racing in this year’s 24 Hours of Le Mans. With the legendary endurance race just days away, Audi shared a video and technical specs of the R18 e-tron ultra it plans to race.


The setup uses a 3.7-liter turbodiesel V6 sending “over” 510 horsepower to the rear wheels, combined with a lithium ion battery pack powering a pair of 75kW motor generator units selectively spinning the front wheels. The diesel is fully stressed in a carbon fiber composite and aluminum honeycomb monocoque, allowing the complete package to tip the scales at under 2,000 lbs.

Watch the video to see some fire blowing out of the tailpipes of the great Audi Quattro of yesterday and to hear Allan McNish describe the linear power delivery in today’s latest and most awesome application of Audi’s all-wheel drive technology.
