I think we need to consider efficiency v's economy.
Honda's are highly efficient, as are top fuel dragsters. However, not very economic (top fuel dragsters).
yeah...
efficiency = power output per cc of engine size and gallon of petrol.
economy = distance covered per cc of engine size and gallon of petrol.
still dont reckon top-fuel dragsters are either efficient or economic...dont they use like 15 gallons (50 odd liters) per 400m? so they sure as HELL arent economic

sure they output MASSIVE numbers and cover that 400m faster than anything on wheels...but i dunno how efficient that is

there'd be a fair amount of wastage

those flames pouring out of the exhaust pipes would reduce their efficiency rating i would say...
