Are single cab trucks faster or more fuel efficient than something like a crew cab

Question

dont give me any c**p like well it depends on the engine and all that, lets just say everything is the same except the cabs

Answer 1

Yep, because it weighs less!

Answer 2

only the weight will make a difference

on the single cab the mpg will be a little better but  i would be suprized if it increased .5 mpg

on speed, if u raced them on a 1/4 mile it would be down to the drivers reaction to determine the winner

over all it does do better but not enough to notice  

Answer 3

No c**p - If all else is the same, including the bed length, the standard cab model is bound to use less fuel, because it weighs less.
