[Kevin]

New Chevrolet Corvette V8 is 6.2 liters, designated LT1. Not the first time a Corvette engine has that RPO code.

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

LT1 is the first OHV engine with Direct Injection

i'm actively not interested in owning one now

And a big cliff at that.


================================================== =======

See what the increased compression did to the torque on the "new" LT1 ? Not bad !

I'm surprised at the discplacement staying up at 6.2 liters for the new GEN V small block Chev engine.

There seems to be a lot of new technology being used in the new C7 Vette engine wise, but quite a bit of it has been used prior in other platforms.
eg.DOD(Displacement On Demand) later renamed AFM(Active Fuel Management used in many GEN 4 engine such as 6.2 L99 and 5.3 truck engines.

VVT-Variable valve timing was used in earlier engines such as the 6.0 LY6 and some 6.2 GEN IV engines.

Good thing about doing so is that the GEN V LT1 might be a well integrated and polished engine.

Buy your 7.0l(427cid) engines while you can.

Corb,
