yeah, but wouldn't you rather have a V8 that uses some more of the tricks that the V6 uses to get better mileage? Direct injection and variable valve timing are both standard on the V6 Camaro, but lacking in the V8. I wonder what kind of highway mileage the DI 3.6L V6 would get if AFM were added?

).With DI, there isn't as much to gain from AFM, due to already-reduced throttling losses. Plus the V6 would have to operate in 6 cyl mode more often.
I think that AFM is kind of a dead end -- easier than putting in DI, but ultimately will be replaced by DI.
I'm happy with the Camaro powertrains, and I won't miss not having a 330hp 5.3. I wouldn't have bought one of those anyway.
Actually, I'm kind of hoping the 2010 G8 ends up with the L99 too.
