Do you mean the Audi Le Mans Quattro? Or an LMP car? The Audi makes 910hp, unless it has a lot of miles, in which case overhaul the engine. Same logic applies to every car in the game. Cars with many, many miles will permanently lose some power (my Formula Gran Turismo made 941hp until it hit 8,000 miles, then it made 938, even after an engine overhaul. Now that it has well over 10,000 miles it only makes 924, like I said, even with regular engine overhauls at approximately 1000 mile intervals.) So regardless of whatever car you're talking about, it either needs an overhaul or has permanently lost some power.
