A few more details have leaked out on Audi's future diesel-hybrid supercar, which will transfer elements of its Le Mans-winning R18 diesel hybrid powertrain into a roadgoing car.

Still in development and not even named, the unusual through-the-road hybrid would have a combined power output of at least 700 horsepower, according to Auto Express.

With an unspecified turbodiesel powering the rear wheels, plus an electric motor on the front axle, it would target a 0-to-60-mph time of less than 3 seconds and a top speed over 200 mph.

The carmaker's R18 TDI e-Tron quattro won Audi's 11th Le Mans victory last June, featuring the same setup, with a V-6 diesel and an electric motor at opposite ends.

The goal, according to its technical chief, is the absolute best supercar on the planet.

Which is, to be fair, what most makers set out to build.

Still, Audi has unparalleled experience building the highest-performance diesel engines in racing, so it's a not a stretch to imagine the maker transferring that into a supercar.

And with the all-electric R8 e-Tron project on hold or cancelled outright, Audi clearly needed a supercar entry above its R8 range to compete with cars like the upcoming plug-in hybrid Porsche 918 Spyder two-seat roadster.

Much remains to be learned about the project, and it won't arrive any time soon.

Earlier reports suggested it may not go into production for three to five years.

By that time, every new car on the road will consume less fuel than comparable models do today--and even supercars will follow form.
