I have two cars that will turn 2,000 RPM at 70 mph. I drive a lot at that

the engine was turning 2500 rpm. After driving it a while I decided I'd not
buy one for myself. Why? I keep cars well over the 100,000 mile mark.
Given that I may drive it 100,000 miles at 70 mph, the crankshaft will have
turned 43,103,000 times more than my present car. Lots of wear on them
bearings.


But then the engine turning 2,500 rpm is only carrying 4/5 the load, all
other things being equal.
