GM applies for LT4, LT5 & LTX trademarks

[Mook]

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum – which provided advance intel on the C7 like these leaked images – believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.

Seeing an LT5 again would also be déjà vu – in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.

The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

But this could be them just renewing the names to keep them for GM. Just like when they did the Chevelle and El CAmino not to long ago. People thought it was for the SS but it was just renewing them

Just as long as they aren't turds like the early generation of lt motors we will be fine

They just going to stick these motors into FWD sedans and put SS badges on them.

I'd hardly call an lt5 a turd. Those things were running low 12s in the early 90s

The original lt5 was a beast of an engine. A friends dad ran road race slicks and a 300 shot on his and was running 10's.

On June 2, you should see a couple of LT-5s that run 10's N/A.

 

[Bob Kazamakis]

I don't know what that means or insinuates.....

What it means is you don't need a 300 shot to be running 10's w an LT-5. It can be done N/A. Granted, they are not stock. No issue w what you posted.

 

[Bob Kazamakis]

I'm saying those were the only mods it had......

He used it for fun at autobahn but took it to the track once or twice.

It certainly illustrates that it doesn't take much to have this motor really perform. As it came from the factory, it was rather restricted.

Were you at the Haibeck open house?

Were you at the Haibeck open house?

Yes I was but didn't bring my ZR. It was still in surgery at the time.

 

[Lead Pipe]

Ah, I got there really late without my Vette. Just in time to help clean up. Do you know when the Vette shoot out is at 41 this year?

 

[Xfirez51]

Looking at the Crown Point Corvette schedule, doesn't say anything about a
CORVETTE Challenge this year.

 

[Lead Pipe]

Hmmm, you guys usually do something at the 41 in August, right?

Our FBI ZR-1 group has participated over the last 4 years w the Crown Pointe club. But they've been the ones to organize it. Haven't seen anything from them yet so far. We won the club trophy in 2011. Just a bunch of C4s.
