-High speed race cars are generally at near peak efficiency because the force due to aerodynamic drag is maybe 40 times greater than when cruising at 60mph, if they were to cruise at 60mph, engine efficiency would drop, but vehicle efficiency would increase, and they'd probably be in the 20-40mpg range imo.
I was meaning more like if you changed the cam timing so the engine could run
effectively at the new lower rpm
If a Nascar engine can get almost 5 MPG (more on some tracks) at 189 miles per hour then how does that efficiency translate to 60 mph.
You mention drag being 40 times higher at the high speed does that mean that it takes almost 40 times more energy?
If the cam timing and gearing were optimized for WOT at 60 mph would it get
40X5 miles per gallon?
Just thinking.
the engines run at wide open throttle and have very high compression ratios.
