New engines? 2018? - Page 2

Hope it's not DOHC... there are plenty of options with that engine configuration out there and pushrods are part of what give the Vette/Camaro/GM performance their identity. It'll be like a V6 911 :/ just why..? The LS7 did plenty well even without VVT or DI, and it's not like they'll sell enough to impact company-wide mileage in any meaningful way.

I guess we'll have to wait and see.

Based on everything I've been reading, the LT5 will be a large DOHC V8 engine. If this turns out to be true it would be capable of high peak HP figures due to the fact that its DOHC but should retain decent TQ figures as well due the fact that it would be very large displacement for a DOHC engine. Think 550+ HP.

It would also be to large and too heavy to fit in the front of the Corvette or the Camaro, but it would likely work just fine in the new mid-engine Corvette that is rumored to be coming as well.

I would expect the LT1 to continue on, at least for a short time even after this engine is revealed to be used in the "regular" Corvette and the Camaro.

As for the TTV6 in a Camaro. Not happening. Not this generation. The "A" car also includes the Cadillacs, which currently use that engine.

I wouldn't be surprised if the LT5 is reserved for the mid-engine Vette only, even after time. Cost is going to be high, and GM will be passing on every dollar.

Think $100k+ mid-engine Corvette. Pushrods should remain for all other models.

Development costs are recovered by selling more units, just keeping this engine exclusive to a very limited production mid engine Vette will keep the cost of development high and the return on investment longer, neither of which are good for profits. I would not be surprised to see the same engine or derivatives of it available in other models especially ones that will be able to accommodate the larger dimensions of the LT5. Cadillac seems obvious, but I also wouldn't be surprised to see this end up as the power plant for the Z/28.

This engine is going to be huge so if the Z/28 were to have this engine, they will have to reconstruct the strut towers. The LT1 fills up the engine bay already I can't imagine them fitting the LT5.

Mid engine Vette is going to cost a lot of money especially with the LT5. I'm curious to see what they have planned for the other C8 model Vettes.

They also plan to offer the mid-engine Corvette globally to compete with the exotic market and the Ford GT. Expect more like 200k price tags and at that rate, they will make up for the 5 million dollar retool at Tonawonda for producing that engine pretty quickly.

After the first 25-30 units are sold the engine tooling & development are paid for. Sell another 20-25 units and the R&D for the platform is paid off. After that, margins are probably 50% of MSRP and most will be made to order. GM will not lose money on the mid-engine Corvette. Once unveiled, they'll have enough pre-orders, from collectors and affluent clientele looking for the latest toys, to exceed that unit count. They could probably make the first 100 available as a special launch edition for an extra 50k and people will pay it. Then the platform is immediately profitable.

GM said they want upmarket and less volume so they can keep their materials and labor costs down for maximum profit. This vehicle will be the ultimate benchmark to see if it will work. If it does, GM will move toward niche vehicles only at higher prices and likely rehash a crappy Geo-esque brand to sling Cruzes for the unwashed masses.

Also, depending on the angle between the cylinder banks, a DOHC large displacement V8 could fit in the Camaro -- but not in the current Corvette. The current LGX is pretty tall and there is room for a little girth to be added in that design to make a DOHC 6.2L V8 happen.

There are certainly glitches and errors on that list......

The 2.0T LTG and 3.6L LGX are not going away in 2018 that just isn't going to happen... they are looking at offering a 2.0T 1LE Camaro probably as a 2018 model year car.

Considering that the......

I wouldn't be shocked if the DOHC for the LT5 was also a glitch, and that the LT5 is just the production name for a crate motor GM has shown off recently.

IMHO there is a good chance that this will be the LT5 engine that we see coming, that maybe that aero C7 isn't a ZR1 Corvette but a more track focuses Corvette something like a C7 Grand Sport with a aero package more extreme then the Z07 package.
