0 to 60 mph in less than 4 seconds. Entry-level car. 450 hp or more!

New Corvette WILL use cylinder deactivation. Go from 6.2 V8 to 3.1 V4 for better fuel economy.

New V8 engine has 11.5:1 compression ratio. Direct fuel injection, cylinder deactivation; continuously variable valve timing; active fuel management

450 hp 450 lb-ft of torque. More than 26 mpg!

New engine has a unique and complex piston head.

New LT1 V8 has 50 lb-ft more low-end torque than current LS3 V8; matches the LS7 V8 from the Z06.

LT1 engine to be built at Tonawanda engine plant in Buffalo.

Premium fuel recommended, but not required.

Spark plug is in the center of the chamber. Intake and exhaust valves are reversed.

There will be an optional 11.5 quart dry sump oil system available for the new LT1 V8

6,600 RPM fuel cut off in the new LT1 motor

All the new technologies on the LT1 make it a heavier motor than the LS3

Patent-pending PCV system

Final performance ratings will come in 2013

LT1 Engine build animation video --> http://www.youtube.com/watch?v=9E-DQ1qQyJk

Peak horsepower around 6,000 RPM; peak torque around 4,000 RPM

New combustion process to be documented in an SAE paper to be published in the Spring of 2013

450hp up from C6's 430hp! WOW!! Let's build an entirely NEW engine with the goal of a 4.4% increase in HP guys!

I know HP doesn't mean everything...but you have to admit this isn't the engine BOOST we were hoping for?

EDIT: I will admit the 50 lb tourque boost is signigicant!

OK, well 450 is nothing to complain about. I'm sure the "or more" means "probably more", but I'm now not as unhappy as I was when Keeks said 430. (Although, he did say "CLOSE to current base power".)

I don't have a problem with cylinder deactivation. I've seen it in action. The switch between the modes happens VERY fast and seamless. Saving some fuel doesn't bug me one bit.

Stop/Start may bug me, but not cylinder deactivation.

The Corvette has been rated at 26mpg highway since the 80's.Nothing to brag about there other then the power output has doubled since then. Everybody and their mother is saying 5.5L.The C6R's are running 5.5L. Who told you they will put a 6.2L in there?

Anyone who has driven the AFM trucks knows that you can't even tell when it's in operation. I will be surprised if this car doesn't get close to 30mpg in manual or auto form.

Only problem is that guys with aftermarket exhausts might have to find a way to disable it if they want to hear all 8 cylinder all the time.

In denial? By your own admission, the C6r runs a 5.5, then why isn't that motor in the C6? Think it may have something to do with the rules?

If the 26 is combined then that's awesome. The torque plus a lighter base Vette means the C7 will out run an LS3 C6 easily. I'm not crazy about the AFM but that can be tuned out. With the high CR and direct injection this car will have huge dyno gains and scream with a good tune. Best part is that with DI it's possible to run crazy HP numbers on 87 octane!!

Realistically, what were you expecting? C6 Z06 levels of performance and power? With 450-460hp it will still outperform almost all of its competitors while achieving good fuel economy at a reasonable price.

You still need space for the rumored S/C model. No need to go overboard for a base model car.
