Message If you notice, the turbo V6s never seem to get better fuel economy than V8s of comparable power and technology.

I mean let's compare the Z with its TT V6 to the Corvette with its larger V8:

Or, what about a couple years ago when Ford announced that their new EcoBoost V6 would enable their pickup trucks to get better fuel economy than the old V8s? Then Chevy released their new pickup truck with a new V8 and it got better fuel economy than the Ford.

I really think that the efficiency increases in the new engines is due to their more modern design and direct injection rather than turbocharging. Because even when non-turbo engines get direct injection they gain power and fuel economy.

It's to the point that newer mid-sized cars that get the automaker's latest direct injected engine get better fuel economy than their smaller, lighter econoboxes that have engines with less power and displacement.
