This morning at an event for the media, General Motors announced its next-generation V8 small block engine range that will first debut in the C7 Chevy Corvette. As we reported yesterday, the first mill of the new LT range — the LT1, is 6.2 liters in displacement and makes a preliminary 450 horsepower and 450 lb.-ft. of torque. We expect those numbers to rise.
The LT1 sports an astonishing 11.5:1 compression ratio thanks to direct injection, features active cylinder deactivation, 2 valves per cylinder, and a 6,600 RPM fuel cutoff. It’s expected to achieve more than 26 MPG and weighs in at 465 lbs (211 kg).
Production will take place at GM’s Tonawanda engine plant in New York.
Expect a deep dive into the new mill later today.

LT1? I guess it's OK to use that again? (1970,1992 Corvettes had new LT1 small blocks). Of course the big question for the enthusiast who does'nt want or can't afford a Corvette, Camaro, CTS-V or full size GM pick-up/SUV is: How much is the 2014 SS sedan going to cost with one of these new LT motors? I'm guessing $42-45K.
Considering you can buy a Camaro 1SS for $39,500 before GM credits coming off (here in Canada), I can't see the the 2014 Chevrolet SS starting around $42,000. I'm guessing it will start around $36,000 to $38,000.
My guess is based on two ideas:
#1 the 2009 G8 GXP was about $38K, which has to be the closest previous
comparable vehicle?
#2 the reports I've read to this point state the SS sedan will be a limted production
car, no where close in volume to the Camaro.
Which version was posted before?
That pic and story came out in July, if not earlier

Rocky, a few things to consider:
1. Not sure if you read the entire piece, but the information (story) was breaking news as of the morning of publication. We were the first to have this up that day as we were attending a GM press briefing and wrote this piece from the briefing itself. The specifications of the engine, including its power numbers, displacement, fuel economy, and other specifications have not been available until now.
2. The photo we initially used was one released by GM this summer, as we simply couldn't use the photos of the LT1 we snapped at the event itself. Since then, this has been updated.
Let me know if you have any further questions.
What about putting this on the camaro??? Will it get heavier??
I don't understand why they resurrected the LT1 name. Why not name it with the LS series??
It's not a reserection of names, rather, GM's RPO code nomenculture.
- - -
These are three hypens that can repesent either a letter from A to Z or a number from 0 to 9. That's 18576 different RPO codes.
As a rule of thumb, if an RPO code begins with an "L", it's an engine.
GM can reuse codes, as they have done here with the GenV. This LT1 shares absoulutely nothing with the Gen2 block; only it's name. It's possible GM could have called the GenV the LK series or LU or anything else begining with "L".
Considering the last Gen2 block to have an LT RPO code was in 1997, I doubt many people are going to be confused by the new name.
How many millions of dollars does it take to get an extra 14 horsepower?
Well clearly they werent just going for power and torque. I bet this engine with a supercharger strapped to it in the next ZR1 will make 700+hp
So I can go order a Silverado LT1 with an LT1?.....but not a Camaro LT1 with an LT1?.........this is too damn confusing. I agree with Mike, they should have named it something else.
To clarify, the 6.2L LT1 engine is the RPO code that will be used for the base Corvette V8 (confirmed) and the refreshed Camaro (expected). We do not yet know exactly what sort of differences we will see with the new Silverado/Sierra V8 engines, or what they will be called -- but expect direct injection and the new combustion system.
It has active cylinder deactivation previously called active fuel management. Which was the new name for displacement on demand. Just like the L 99 engine. So it is actually 50 hp increase.
So Silverado 2500 replacement engine. That is a mill badly in need of being taught about MPG.
