Haha... don't get me started on the Audi R10s. Yes, they're terrific cars, but part of the reason for their winning streak is that the LeMans rules makers underestimated the power of the diesels, and gave them less restrictions than their gasoline counterparts.
That's always the case with alternative engines in racing. People find something that works better because the rules are kind to them (diesel, rotary, powerful turbos in F1) then in a year or two, the race-governing body changes the rules to make it fair, or sometimes, they change the rules so much that the oddball team then has no chance of winning.
Hopefully they get the rules right next year, so that we can see an even mix of powerful diesels and gasoline cars in the next LeMans.
One problem with Diesels in the US is the insane restrictions California puts on diesel emissions. Hope they can work this out without making diesels too expensive...
