My guess it will be a tough call on what comes first, ZL1 or Z/28. Ford has announce the GT350 and 350R. But we also expect Ford has a GT500 on the way.

I also expect the whining for these two starting around ohhhhhh May 17th.

They really don't have to indicate anything. The only have two engines to use and one has been confirmed for the SS. Unless GM does something really stupid and drops the supercharged Camaro, the LT4 will end up in it.

There really isn't a call to make. It's a supercharged Z or nothing.

I'll bet 25 cents that there will be more performance engines available in the 6th Gen product cycle.

Maybe. But I'm not convinced.

They could be working on a third...focused engine right now...in tandem with the Camaro Six's development....for a 2nd, or 3rd model year reveal?

Perhaps a high-revving, naturally-aspirated track engine to serve as a successor to the LS7...and a GT-350 competitor?

Agree. The LT1 and LT4 are complete and powertrain is focusing on the future. This Cadillac article supports the theory that more is coming.

...Cadillac chief engineer Dave Leone told Car and Driver when asked about a more aggressive version of the ATS-V. The extra aggression is likely to come from extra power, stiffer suspension and lighter weight...

Another source told the magazine that the more aggressive V-Series tune could be available as early as 2017.

I'll see your 25 cents and raise 25 cents that the LT1 and LT4 are it for the LTx.

I doubt it. The Camaro hasn't had it's own engine since the DZ302.

I saw that and thought it might indicate a new LTx but I figured it would end up being another turbo engine.

I have friends at several OEMs that work in Powertrain. They are going to work every day as far as I know.............


I have no clue what they are working on only that there is work for then to do.

[Bhobbs]

I'm sure there is plenty to work on, just not another LTx V8.

We really have no idea what GM Powertrain's product plan is for the LT series. It would not be unthinkable for additional engine models to be in the works. Remember, they begin with the end in mind and they know the end. Just sayin.

Seems to me GM is consolidating the engines, which is why the LT4 was made cheap enough to go in more than just the Corvette. The only LT, LS and LT engine that did not go in a Corvette first was the LSA and that's because they already had the LS9 which was better. If there's going to be another LTx, there will have to be another Corvette to justify it.

I have no problem with a Grand Sport.....................that provides an engine to the Z/28

It would be interesting to have a GS and Z/28. Both stripped out, light weight track animals. I wonder how much weight can be stripped from the Z06 wide body.

[Mr. Wyndham]

I don't think another Corvette model is required. I think the company has grown out of it's infantile "Corvette gets it first" mode of thinking. That car's not being spoon-fed anymore.

They could stick whatever engine they come up with in the "Z/28", and in a rear-engined Cadillac...

When GM developed the LS7 and LS9 those power levels broke new ground and the materials and assembly techniques were expensive. Bringing the cost down IMO was maturation and comfort pushing that high. We don't know that they've consolidated anything.

You may be right that the LT4 is the last high performance V8 GM develops but I doubt it. A 650 HP V8 is impressive but has already been surpassed by the other US brands years ago.

Just curious what gives you that impression? The Corvette still got the LT1, LT4, M7 and A8 before any other vehicles.

That may be true. I'm sure getting the LS7 to rev to 7k was part of the reason for the costs. However, the LS3 with the GM Power Upgrade Kit can rev to 7k but the only difference between it and the stock LS3 is the cam and heads.


I don't think the LT4 is the last performance V8 GM is going to build. The CT6 is supposedly going to get a TTV8 but Cadillac is wanting unique power trains, so the TTV8 may be a new DOHC engine. I just don't see GM building another LTx. Unless they rework the LT1 with CNC heads, a hotter cam and more compression. That's the most likely path but I wouldn't hold my breath for it.
