[QUOTE="Driver72, post: 9742734, member: 105832"] Mr. Coltrain :) Drivetrain losses vary widely for each car and from each manufacturer. There are a ton of things that can affect it. Even how sticky/wide the tires (as well as the tires weight) are going to affect how much of the power gets to the road. But really it's how much power is sapped up by the transmission, the brakes, and anything the engine needs to turn to make the car go. I've dynoed a lot of cars and based on the results I've seen and the power claims of the engines here's my take: FWD has losses of 10-12% RWD has losses of 12-15% AWD has losses of 18-22% With some cars where the manufacturer underestimates the power of the car (say a BMW 335i with the N54 engine that's rated at 300 but really makes 325 ish) it's harder to actually tell how much is being lost to the drivetrain simply because you don't know exactly how much power the car is actually making since the manufacturer has flubbed the real power ratings at the "crank".
