Audi wants to get the most out of the diesel technology it developed for the now-defunct R10 Le Mans racer. It’s dropped the engine into the Euro-only Q7 V12 TDI and is possibly installing it into a version of the R8 , but that still might not be enough. Now Audi is rumored to be loaning the engine to its upper-class cousin for the next generation of the Bentley Arnage .
At this point nothing surprises us from Bentley. The company has been long-rumored to be considering diesel technology, and its engine choices have been anything but conventional . It’s even been rumored that Bentley has tried to stuff the W16 engine from the Bugatti Veyron into the next Arnage .
