"Adding to" the corvette options anything other than a v8 or FE/RWD will kill it. Chevy has set a standard with the corvette due to its longevity that cant be changed. It would be like Porsche changing the overall design of the 911 or using an engine other than a flat six.

Will Chevy make a mid engine car v6 supercar? Possibly, but I don't think it will be called a Corvette.

I just listened to a clip of the Ford GT'S v6 and it sounded terrible. The exhaust note may not matter to some but it is important to many enthusiasts.

I hope it comes in a 1.8L 4 cylinder turbo.

id actually kill to have a real high revving NA v8 (like 8000-9000rpm like the Audi R8/lambo, GT350 mustang or a ferrari) in my 2017 GS...

The relationship of audi and Lambo sharing for R8/Gallardo will likely be in the future for Corvette and Cadillac with the mid engine car, then potentially with a sport luxury car that competes with Panamera under the Caddy badge and uses core architecture from Corvette.

I could see a hybrid V6 application running forced induction, find its way into something...sure. That said though, there will ALWAYS be a V8 Corvette available. I've heard countless powertrain engineers in GM say that, internally, that is something they feel will never cease to exist...it'll kill the brand.
It would work IMO if it matched or exceeded the 3.5 Liter V6 in the Ford GT. Double overhead cam, 4 valves/cylinder, variable intake separate fron variable exhaust, twin turbo and 3 more hp at 650! If Ford can do it so can Chevy! And the Ford egine has both DI and port injuction so I don't have to use a catch can!

We got past round taillights, we can learn to accept modern technology!

I was thinking about it and something like the LZ9 with 240hp and 240ftlbs could work. Modernized that engine could work and give better gas milage and a lower cost.

but would corvette owners go for that?

honestly I would be interested.
Here's a thought. The Corvette almost died with that 6 cylinder in it. It was saved by putting the V8 in it (and a better tranny).

I would not be interested in a 240hp Corvette. I'd just go buy a Mustang GT. Or even a Subaru WRX STi. Or a Ford Focus RS. They are less expensive and have more horsepower than that. The horsepower and torque are part of the reason I purchased the Corvette. You take that away and you might as well be selling a Mazda Miata.

I wouldn't have a problem with GM putting a 6 cyl in the Corvette provided it made an appropriate amount of power (400+ hp).

There's already a few cars that fit that market. Toyota 86, Scion FRS, Subaru BRZ and WRX, Mazda Miata, etc.

Corvette doesn't really compete with those cars.

Would I consider one? Absolutely. If I couldn't afford the Corvette, the FRS would be a front runner. Unfortunately for Toyota, I can afford the Covette and the FRS didn't have enough power, presence or features to make me consider it.

I wonder if the combo of the V6 plus turbo is even much lighter than the LT1? I doubt it's much lighter as the LT1 is already pretty dang light.

If they use a V4 or v6 in the C8 it would not make me NOT buy a Vette... Cause I still need a C1, C4 and a C6...
But if the C8 onwards do not have a V8 option then I will not be buying. I DO NOT care that a Turbo or supercharger can get yada horsepower. For me its not the HP cause I'm not racing anyone anyways. Its about the Growl, some fun acceleration and sporty looks. Looks like there is gonna be an upswing in the value for Classics!

Then mull this over. Why would Cadillac spend the time money to develop a 464 HP Twin Turbo V6 for the Cadillac if they could just go to the parts bin and take out a 460 HP LT1 instead?????

There must be some reason behind their madness. Maybe it is lighter, maybe because the Europeans are doing it(TT V6's), maybe because they don't want the Cadillac to come across as just a re-badged Chevrolet with a Chevrolet motor out of a pickup truck(they already got burned pretty bad doing that back in the day).

One thing we do know is that the V6 is physically smaller than the LT1 V8 and in a mid engine sports car, space is at a premium. A V6 engine that is 4-5" shorter in length fits into a smaller space than a big V8 does. That means the wheelbase can be shortened that 4-5 " without reducing the cockpit size, resulting in an automatic decrease in the car's weight(everything else being equal).

I'd say it's about fuel economy not weight. But since you post like you have a chip on your shoulder I don't think I'll discuss it further with you.

Why is Cadillac sending some of they're operations to Bowling Green KY the Corvette Plant, their going to be two models, might use the Cadillac V6 with the twin Turbo's in both

Because a new mid engine car will need a modern small displacement V6, with 4 valves/cylinder, independently variable intake and exhaust timing that at EPA drive test rpm's get very good mpg and when cranked to 6500 rpm provides 470 hp with twin turbos!

Then when the Z06 mid engine is released as a Chevy it will be similar (but better) than the 3.6 liter engine in the Ford GT! Similar good mpg at the low rpm EPA drive test range and a dual turbo version that produces 650+hp @7000 rpm. Like the Ford and Toyota it will hopefully have DI and port injection so I won't have to transfer the "Catch Can" from my Grand Sport.

My marking guess as to why Cadillac first is so GM can justify bringing it out at the needed high price. They will justify the $125/150,000 by adding things that sound good for example a Bang and Olufsen sound system with 15 speakers and a lot of insulation so it sound great. Maybe lower performance quieter tires. They can add the "detection stuff" some folks want (and those who buy it can afford!) Maybe Gucci logo'd interior!

Then the Chevy version comes out two years later when they learn how to build them more economically with our usual some Mulan leather but mostly vinyl, cheaper seats, little noise insulation and Bose! But the price will be $75,000!

there are a lot of corvette traditionalists here that would not be customers for a v6 corvette.

however there are a lot of potential customers for whom a twin turbo v6 would be a selling point.

nissan manages to get the big heavy gtr doing 3 second 0 to 60 times with such a motor.

i wonder how many buyers would pick the ford gt with its 6 cylinder over a z06 if the price was comparable.

many consider corvettes to be what retirees buy as their retirement car. if chevy wants to appeal to a younger demographic a twin turbo v6 wouldnt be a bad choice assuming the performance was as good or better than a v8.

Horsepower is not the be all, end all for a street car. I want smoothness, which a V6 doesn't provide. I was sound, which a V6 doesn't provide. I want something impressive when I open the hood, which a V6 doesn't provide. I don't need my Corvette to sound and feel like a mid-80's Buick Regal. The V6 is one of the worst possible cylinder layouts for balance. You are much better off with an inline or flat six.

Based on the leaked engine codes, it doesn't look like we need to worry about it. If anything it will be a 6.2L V8 with DOHCs, and even turbos. Now that, I can get excited
about. We may get some real RPM, while retaining our beloved large displacement.

2017 Z06 with a 6.2L 650 HP engine with an auto transmission gets 13 city/23 highway.

Now lets look at the Ford GT with a 3.5L HP 647 HP with an automatic transmission that gets 11 city/18 highway.

Now lets look at the Audi R8 with a 5.2L V10 with an automatic transmission with 610 HP that gets 14 city/22 highway.

If you want to compare lower HP models(460-470 HP), then the base Stingray has a 6.2L V8 automatic transmission with 460 HP that gets 15 city/ 25 highway(30+ highway in the real world), but the Cadillac ATS-V with it's 3.6L V6 and 464 HP automatic transmission gets 17/25 MPG. Not much of an improvement(only in the city) and the ATS-V won't accelerate 0-60 in 3.2/3.4 seconds(it will do it in 3.8 seconds with a top speed higher than the Corvette at 189 MPH, because of it's better aerodynamics vs the C7).

When you look at cars with comparable horsepower, the small displacement V6 gets worse gas mileage than the larger displacement V8/V10.

My honkin' 7L 505+ HP C6 Z06 is rated at 15/24, but in the real world, it gets over 30 MPG on the highway. I can add an E-Force to it and have 657 HP(comparable to the C7 Z06 and the Ford GT), and my city/highway gas mileage wouldn't drop below what I now get, as the EPA does not measure fuel economy with your right foot on the floor.

That's my argument for the Corvette staying with a big V8.
