How Much Power Lost

I was just wondering what power is lost through transmission for a 4 wheel drive i read the other day around 40-50 bhp is this true, and also what figures does subaru quote when giving you the bhp is it at the crank or wheels????????????????
Cheers

Re: How Much Power Lost

i think power loss can vary. a rwd will have more losses than a fwd, and a 4wd will have more than a rwd. a car with a centre universal joint in the prop will have a slight power loss over one which hasnt. you are right though in saying the losses are about 40 to 50 bhp. the power figures quoted are usually at the crank in optium conditions to make the most power
