No more engine whine! Could Formula 1 go diesel?
A Ferrari test driver now says that Formula 1 may be ready to allow diesel after the success of the Audi oil burners (shown) at LeMans. An Indy racer powered by a Cummins diesel once sat on the pole for the Indy 500, but I couldn't find any mention of a relatively modern Formula 1 car trying diesel technology. F1 engines have always been known for their high-revving screams down the straightaway, so it's unlikely that the muffled turbo-diesel exhaust note would be welcomed.
Now that fuel economy and green thinking are more important than high-pitched whines, perhaps the timing is right for Cummins to return to racing.
