I mentioned this in another post and was requested to post it here. it is a break down on how much enery is used or lost durring normal driving. This was done on a european car with 4 cylenders, manual, rear wheel drive.
35.3% exhaust heat
30% engine heat
8.5% internal friction
4.2% charging change
6.9% air resistance
4.0% rolling resistance
6.4% translation losses (acceleration)
0.6% rotary losses (acceleration)
0.3% axels
0.9% transmission
0.4% clutch losses
1.5% alternator
1.0% power steering pump
for all you power nuts out there I though this might be interresting.
