The one to watch is the v6 with 300 HP. It gets an EPA of 26 mpg and stories all around GM that they have test mules with this motor SUPERCHARGED with 400HP VVT with fuel management system and are looking to 26 to 28 MPG. Don't underestimate the gear heads at GM they are alive and well.
I had lunch last year with the chief cylinder engineer for GM and he told me the Direct Injection on the V6 will give it outstanding power and gas mileage. A supercharged variant is being tested.
