This is GM newest monster.

I assume the C7ZR1 will have the LT5...700 HP?

While I hope they don't call the new ZR-1's motor an LT5, I like how this new LT4 has deliberate styling cues throwing a bone to the C4 generation.

You know what's good about this one? No optispark!

Why not?

The original LT-1 had a carburetor, The LT1 had fuel injectors, and opti, the new LT1 has direct injection, and 8-coil packs.

Things tend to evolve. If GM calls the engine for the ZR1, the LT5 great if not they will call it something else.

...maybe L83

I like it, but it needs a red intake.

Not sure what styling cues your referring too?
Other than it being a V8 engine, I don't see anything about this new engine being even remotely styled like the C4 LT4 engine.

GM has recycled many engine names throughout its history.

The current Gen 5 Camaro with automatic transmissions use the L99 engine.
This is an LS series based engine (like the LS3)

There was also an L99 engine based on the LT1 we are used to seeing.
Same design only smaller displacement and used in the Chevy Caprice.

The LS7 engine name used in the C6 Z06 (and upcoming Camaro Z28) is recycled from the original LS7 454 Big Block of the '70's.

If an upcoming C7 ZR1 (or whatever name they decide to use) ends up with an LT5 engine name, it wouldn't be a huge surprise.
In fact, based on past history it would be totally expected.

The LT4 styling is the ribbed supercharger intake cover. They could probably paint it red at some point. It is all academic for me since I'm sure the next Z06 will be 90 large.

GM is certainly more interested in selling new Corvettes than preserving the name of a 20 year old Lotus engine for a small group of dedicated followers. Why shouldn't they name it whatever they want?

mike100

It really is just a name and they could market something new if they wanted a new model in the low or high price range...sort of like the platinum edition trucks are there to convince people to buy a truck that costs $65k bux. The future ZR-1 will be outrageous, but what I wish they had done was follow Ford and make a lightweight DOHC engine like the Coyote 5 liter...even for the base engine.

Corvette brand managers realized a few years ago C4 and C5 had garnered a gold chain image and they attempted to shake it off with C6 by removing some traditional Corvette heritage in order to appeal more to Porsche, BMW and Mercedes buyers.

Insiders have suggested Corvette would likely have more success in this market segment if Corvette was spun off as a separate division of GM without the Chevrolet name.

How about an entry level version fixed roof coupe with a 400hp pushrod V8 or a high end version with a supercharged double overhead cam V12?

It's just that LT5 is a bit of a black sheep. GM Powertrain didn't design it, which makes me think they'll not use the name in the first place, and the LT5 was also the only DOHC, 32-Valve engine to go into a production Corvette. Any new engine using this RPO and not meeting the DOHC criteria would just seem like an impostor to many that using the "LT5" badge as marketing would work on.

It wouldn't cause me to give the car the cold shoulder or otherwise not buy one if I could, it would just a be a somewhat odd move for them to call it "LT5."

Didn't GM file for L88 fairly recently?

The supercharger cover has those chrome strakes going lengthwise, which is a little bit of a throwback to same detail on the intake manifolds for LT1 and LT4 C4s. Since I haven't seen that detail on any other Corvettes, I assume it's just a small nod thrown our way.

Also, I remember seeing the CAD renderings shown by Keeks for this engine before the Stingray's unveiling. They were red in there, maybe that will show up in production.

In recent years Corvettes and other new factory high performance cars have redefined what we thought a "muscle car" was. Muscle car fever was officially reborn when we began to rethink the value of the sixties factory hotrods (especially Corvettes) in the early seventies about the time the gummit put an end to factory high performance and mandated manufacturers could only offer new models which met constantly changing federal safety, fuel economy and emission standards. With little in the way of performance available from most of the automakers through the eighties and into the nineties the old factory muscle cars started skyrocketing in value and prices escalated up through the stratosphere. That should no longer be the case or at least for much longer as anyone with fond old memories of them or someone contemplating a muscle car purchase will get a reality check rather quickly when they take one out for a test drive and try to cope with it in today's environment. Which one is really a muscle car? Any of the new Corvettes or one of those old antiques with a carburetor, giant steering wheel and drum brakes?

The V8 32 valve engine is unique. The only ever push rod less Corvette engine. Like Mike said, RPO LT5 is just a name, and like Johns, Peters, Michaels, and James they share the name, but are all different.

Greg Gore

Corvette was successful for a long time being a low cost US built sports car with a pushrod passenger car V8 which was able to compete with the high priced European supercars similar to a Timex compared to a Rolex and the $32K optional LT5 was directly opposite that premise. Don't forget, Porsche owners are very sensitive about being seen driving a Chevrolet and the ZR-1 option was affordable mostly to the well heeled who usually only bought Porsches

L82 was the 3.1 V-6 in the 97+ generation Malibu.

Having a familiar name to a particular vehicle makes for customer loyalty, but I see no need to carry it over into the engine designations. Naming a new and completely different generation engine the same as an older one just causes confusion down the line. Try to talk to some counter monkey about buying replacement parts a couple of years down the line. There are plenty of letter combinations left in the alphabet.
