So while the typical auto engine may not be designed to produce
maximum continuous power, they sure can do it.


Even the highest power ratings (for offroad machinery) is for not much over
50%, with car racing next. Just compare the mpg with specific fuel
consumption eg 20 mpg(imp) @ 60 mph = 3gph = 21 lb hr ~ 40 hp @ 0.5
lb/hp/hr for a 150hp motor.
