dominating R10 TDi racecars may leave the American LeMans
series because of a rule change by the organizers. Although ALMS nominally uses the rules defined by the Automobile Club de l'Ouest (ACO) for the 24 Hours of LeMans, they do occasionally tweak minimum weights, and air restrictor sizes to help even out the competition. The ALMS has increased the restrictor size for LMP2 class cars this year to allow them to compete better with LMP1 cars, which includes the R10.
Since Audi is planning to run the R10s on a special biodiesel fuel
this year, it would be a shame if they decided to quit the series because of this change, especially since the gasoline powered ALMS cars will begin using an ethanol
blend this year. Hopefully, Audi will take it in stride and continue demonstrating what can be done with diesel engines
to race fans all across America.
