Exactly
Just a point about engines in general. The number or cylinders is only
one
measure of its characteristics. An Offenhauser 4 cylinder can out perform
any GM V-8 ever made and it gets terrible fuel mileage. Engine
performance
is a function of displacement and efficiency and what the engine was
designed to do. High rpm for speed, low rpm for torque, etc.
I know of some 4 cylinder economy cars that can out accelerate vehicles
with
8 cylinder engines with superchargers.
Blanket statements that one engine is going to be more economical based on
the number of cylinders is just plain wrong.
