Audi is developing plans for a Le Mans-inspired diesel hybrid hypercar that would sit above today’s R8.

Insiders suggest the car could be badged as Audi R10, and is intended to be a road-going mirror to Audi’s Le Mans-winning R18 e-Tron quattro.

That car used electricity generated from a flywheel system to power one electric motor for each front wheel, improving the car’s performance, when pulling out of corners at speeds above 74mph.

There are no further details about what would be Audi’s flagship model, but expect a carbonfibre monocoque and a diesel no larger than a V8. The V12 diesel in the experimental R8 was judged as ‘too heavy and having too much torque for existing transmissions’ according to Audi sources.

Autocar has also established that a prototype Bentley Flying Spur powered by a V8 diesel has recently been under assessment at the maker’s Crewe HQ.
