thing is engines breathe.

smaller engines breathe less and use less fuel.

turbo them and they breathe more and make more power.

NOW pay attention.

a smaller higher output engine will weigh less and not sacrifice as much power.
thats the whole point.

weight savings. its not direct for fuel economy, but it does help.

notice the elimination of fasteners in the 08 door handles.
spare tire only an option?

aero only goes so far for highway economy.

weight is what brings up the city numbers.

think about it yall.
