I recently saw a diesel dragster do sub-7.9 in the 1/4 mile, over 200MPH in the last trap. This was an exhibition vehicle. There was also many, many diesel pickups in the 10 second range. Amazing what a little manifold pressure and Nitrous or propane injection will do for a diesel engine.
I would like to see an oval or road racing series adopt diesel engines and spur some development. Far more promise in turbo charged compression ignition engines than in hybrid engines.
Audi had an impressive diesel entry in 24/hr Le Mans ,,, and there is a very entertaining racing series for diesel tractor trailers in europe ,, the flat 12 powered MB tractors put out 1200hp... I think Peugot will have a diesel entry for LeMans next year.. I like diesel myself but I don't know when we'll see them here ... maybe as the donkey engine in a hybrid??
