True to a point. The problem is though, the ACO made it too easy for the diesel powered cars and many manufacturers(of gas powered cars) decided not to run under the current rules which gave the diesels the advantage. That's one place, I believe, that Porsche was a little irked by. It takes great expense to develope a race car only to have the rules changed a yr or two later...I understood that Porsche was looking for at least a 5 yr formula or something in that neighbourhood. Diesel race cars are interesting, but it severely limited the grid in P1 over the last decade because most manufacturers aren't really interested in that type of engine.
