As a 'base-line, what is the current maximum hp offered and mph delivered in new/current Vettes... how far do they have to go?

Maybe they will just put in a 20 speed tranny.

the CAFE milage for the 400 HP 05 C-6 is 28 MPG i can not see how a 150 more HP is going to get 2 more MPG

We sell tooling to a guy who builds blocks and cams for GM. This is where we heard of the HP & MPG objective.

Someone out there seems confident that they can pull it off.

It seems highly unlikely that the C6 could accommodate a 550 HP base engine, assuming the same dimensions of the engine compartment. Is a great leap in technology anticipated? How can a 550 HP engine achieve 30mpg, without some quantum leap in technology? And in 2 years?
I'm betting perhaps 425 HP (at most) by 2007, with mileage holding steady.

Guess what, it can be done! it would take a good computer and variable valve timing ( read computer controlled timing) This is the future of tomorrows engines.

Never underestimate the resourcefulness of General Motors Powertrain.

Direct gas injection improves MPG and maybe they will reconsider DoD.

It wasn't many years ago when 405 HP/400 lbs ft TQ coupled with 30 MPG was unheard of. Three more years and all the engineering work that goes on behind the scenes that the public doesn't see or hear of could yield some very good powertrain results. Just because the C6 is out, doesn't mean the slide rules have been put away, I'll bet these things have been in the works since late in the C4 lifetime, they just need to wait for technology to catch up, work out the bugs, and prep the public for what is coming.
