It seems audi might be getting a raw deal?I'm not sure! They are allowed to use slightly more energy per lap but have much smaller fuel tanks.Is the fuel tank size all about diesel's higher energy density?Perhaps audi arent disadvantaged after all?Can anyone explain precisely?http://www.autosport.com/news/report.ph...

BTW a vaguely related thought- not a question as such;

For years ,as far as i understand it , the rules gave audi's diesels an advantage.Put simply ,everything was equal EXCEPT for the fact that they could run far longer on a tank so saving time on stops.There was just one disadvantage -they had to spend a lot of money to get the diesel engines (and their heavier gearboxes) light enough for racing. Does this sound like a close enough summation of the last 10-15 years?
