GM Inside News Just Released this photo of the Mid Engine for the C8!
As predicted there is no way this double overhead cam Twin Turbo V8 could fit in a front engine Vette! Might be only 4 Liters!
But heck, Ford gets 567 hp out of a 3.5 Liter engine used in the GT! GM is smarter and can squeeze a few more from a V8!
The article refers to what was published previously but says:
"The image shows a longitudinally mounted V8 with turbos hanging low off each cylinder bank and plumbing for the turbos that snake around themselves from back to front as it runs from the rear, to the centrally mounted airbox. An earlier drawing had made the turbos seem like they were mounted at the car's extreme rear, but this image shows they will, in fact, be mounted more mid-ship, closer to the cabin.
The picture appears to show similar thinking as we've seen in GM's 3.0-liter twin-turbo V6 LGW engine used in the Cadillac CT6. The turbos are closely coupled and include water-to-air intercoolers and it looks like the heads will have the exhaust manifolds cast into them."
Lets see a 3 Liter Caddy version appears first followed a year or two later with a more powerful 4 Liter V8 I a vette!
Can you imagine owning a first year edition? What could possibly go wrong?
Assume GM might have planned a Caddy Version first for a year or two. Lower volume due to high price and Caddy buyers not as concerned about performance.
Would not be surprised to see only a 3 Liter V6 that stresses things less. The higher price will keep demand where dealing with "issues" is easier.
With where those tailpipes are located, it sure looks more like a rear-engine car than a mid-engine. Of course, I don't make the definitions as witnessed by a front engine that's considered a mid-front engine car. I'll get used to it. Eventually.
OK, who wants to be the guinea pig? New engine, FI with DI, what can possibly go wrong?
That's why we have a warranty. Plenty of us will gladly be the guinea pig and be having fun why some of you guys sit out a year or two hoping for the perfect car. Not

Corvette Forum Member ZERV leaked this photo on the “Code Name ZERV” C8 thread yesterday. And I thought that Ford GT engine is an In-line 6 that makes about 650 horsepower. The it’s easy to make power, just hard to make it affordable and reliable. A 3.6 liter V6 with two decent size turbos, high boost, and a high redline can make 650hp, but the engine wouldn’t be nearly as reliable as a 4.8 liter V8 with smaller turbos, lower boost, and a lower redline.

Some of us w the original LT5 are getting 550chp out of a 25year old 5.7L NA motor w porting, cams and exhaust. Just shows the potential of this architecture.A few big bore LT5s ie 427, are in the 700hp range NA.
This is definitely a DOHC, how disappointing... these new engines will contribute to much higher price points. The secret to making corvettes so affordable is the shared engine architecture or a truck motor and a corvette motor. Even the Viper could say that.
The only way it is remotely affordable is allowing the LT1 to fit in there. Which apparently is the case. I can see polarized sales of the ME if the base models are affordable and the high end ones are NOT.
Same thing happened to the C4 ZR1, as the pushrod motors approached the LT5's output, sales diminished... and the ZR1 DOHC was never to be seen from again.
what was the reason for the LS OHV engines to go into a corvette in the first place
1: lighter
2: lower ( at least in a fron engine application)
3: cheaper to build
4: reliability
I think 1,3,4 still apply. 2 not that important in a ME layout.

GM's biggest concern is corporate average mpg, IMO! To get a more energy efficient engine, it needs to be a double overhead cam that can vary intake and exhaust timing independently. Probably have 4 valves per cylinder.
Then they can meet the EPA mpg fixed driving path and when max power is used (not part of the required EPA mpg test) those two turbo's provide the power. Turbo's also capture some of that wasted energy going out the exhaust.
Maybe it will be a truck engine as well! They have to improve gas mileage too!

Exactly! Had a first year C6 and a first year C7. Neither had any serious issues (except for a faulty C7 NAV display). If I have the cash, and if I can score a good deal, I would certainly purchase a first year C8.

Really? So Ford can’t sell DOHC Mustangs at “reasonable” price? The original LT4 never approached 405hp. Ur just drinking too much if the GM Powetrain Koolaid.The reason the LT5 got the axe was because it was NIH. It was a Lotus Motor and Dave McLellan shiwed up the Powertrain guys by going outside altho Lotus was part of GM at the time. The Vette will always be an American oddity with its truck motor. Some people at GM and at Corvette may have finally seen the light.You want to be taken seriously in the world of sports vehicles, then shiw ur chops. Quit trying to cheap it out. Nissan made a car that seriously challenged the big dogs. About time GM showed up with their engineering chops and laid a marker down. Stop making the Best Corvette Yet. Make the best sports car. Right now Ford beat them to it w the GT, IMO.Let’s see what they come up with.
