Despite confirmation from Audi that it will return to ALMS in 2008 with two R10 TDIs, apparently it's not officially official. It is well known that Audi holds extreme displeasure for ALMS regulation changes involving weight that were aimed at keeping the LMP1 vehicles like the R10 in close running with the less powerful LMP2 vehicles. Audi believes that the adjustments went too far, as the Penske Porsche RS Sypders won 8 out of 12 races in the 2007 season. For 2008, a 50 kg (110 lb) weight penalty will be imposed on the LMP2 cars for the 24 Hours of Le Mans endurance race, and Audi hopes to see IMSA implement the same weight penalty before it decides it will return to ALMS. When asked, Audi would also not go into detail on whether they would accept the rumored compromise of a 25 kg (55 lb) weight penalty. Come on, IMSA. The ALMS without Audi is a lot less attractive.
