More CAD Images Show the Mid-Engined, C8 Corvette’s Twin-Turbo, DOHC, LT7 in All its Digital Glory
Chevy Tries So Hard to Keep the C8 Mid-Engined Vette a Secret, and yet, here we are…by Robert Moore, on
The last time we saw CAD images for the mid-engined, C8 Corvette, Chevy lost its mind, sending out letters that asked publications to remove the images and it even used the digital copyrights act to have the images removed from another publication’s Facebook page. What Chevy doesn’t realize is that the mid-engined beast we’ve all been waiting for is the world’s worst-kept secret and, as evidence, we’re looking at more CAD images right now. The thing is, however, that we’re looking at a completely different engine setup this time around. Keep reading to learn more about it.
C8 Corvette LT7
Based on what we saw in the previously leaked images, we were likely looking at either an early iteration of the engine or an engine that wasn’t the LT7 that you see here. The engine seen previously (shown below) didn’t even have turbochargers, and here we are looking at a turbo sitting down low, between the exhaust outlets and the intake manifolds – this is, without a doubt, the twin-turbo DOHC engine we’ve been hearing rumors about.
Other differences include the positioning of the exhaust manifolds, the belt routing, the charge-air cooler, and the size of the intake itself
Other differences include the positioning of the exhaust manifolds, the belt routing, the charge-air cooler, and the size of the intake itself – clearly, we’re talking about two different engines. On a side note, that old CAD image has a beefy transmission hooked to the rear, almost suggesting that it was the hybridized engine, which wouldn’t necessarily make sense without turbos, but at this point, anything is possible. To save room, the turbochargers could be added post-cat on that engine, with the flat area above that transmission reserved for the airbox. Oh, the possibilities. Either way, the new image that you see above should look familiar – after all, it is styled after the 3.6-liter LGW:
Much like the engine you see in the newest leak, it has the turbos on each exhaust outlet and the feed heading upward to the air coolers on top too. Now, the new engine looks to have a slightly different intake setup as far as where drawing in air happens, but that’s because we’re talking about a mid-engined setup here. Based on spy shots, the air will likely be drawn in from vents behind the doors. The belt routing between the LGW and the engine LT7 shown above are also quite similar. So, where Chevy to a 5.7, chopped off two cylinders and made it a 4.3 in the past, it’s now taking a 3.6, and adding two cylinders along with some other goodies to make extra power. So what do we know about the C8, mid-engined Corvette so far? Keep reading to find out…
The C8 Chevy Corvette
Official information as of this point is scant, and outside of seeing the Vette with our own eyes and seeing GM rush to have some leaked images pulled from the internet, we have yet to even receive confirmation of the beast we’ve all had wet dreams about. But, that hasn’t stopped us from garnering information from the images we do have, and there’s actually quite a bit.
C8 Chevy Corvette Suspension and Chassis
The Vette will finally get coil springs, a first and a heavy request from Vette guys for years
What we can make out from these images is that the Vette will finally get coil springs, a first and a heavy request from Vette guys for years. It will also run with magnetic shocks, and the upper and lower control arms appear to be carried over from previous generations with minor changes. The very odd thing here is that the rear chassis is downright massive and appears to be a blend of tube and cast parts – undoubtedly designed to cut down on twist (we’re looking at some serious horsepower that the rear end now has to deal with) and increase strength throughout the body. Whether it’s bolted or welded remains to be seen, but knowing GM, it will likely weld in this area, not for strength but simplicity and inability to repair later. The front frame itself looks to be hydroformed rails, which means it’s probably cast aluminum which could be good or bad at this point. Unibody construction might not have been a bad thing for the C8, but we may never know.
C8 Chevy Corvette Drivetrain, Brakes, and Driveline
In the previous leaks, we could tell that the engine didn’t have turbochargers, but this new engine clear rocks dual turbos on each manifold. Those exhaust manifolds, by the way, appear to be cast directly onto the head – something that means there will be no ability to upgrade to headers later if that’s what you’re into. There’s no transmission shown on the latest leak, however, the transmission in the old leaks was boxy and flat. It could have been a manual, could have been DCT, there’s just no telling. It was shaped oddly, and I’ve argued that – especially with the lack of turbos – it was designed as a hybrid transaxle unit, something we’ve been expected with the C8 generation.
The previous CAD images did show that the half-shafts were bolt-on units, which means removal and installation is a breeze, eliminating the need to drain the trans before replacement. Maintenance-wise, the basic stuff should be easy as Chevy has taken care to make the oil filter somewhat easy to get to, assuming it isn’t obstructed somehow once it’s installed in the vehicle. We also have word that the braking system will be phenomenal and reminiscent of what you would expect on your typical Ferrari or Lamborghini. One-piece rotors will be standard equipment, and you can expect six-piston calipers up front as base equipment while eight-piston units may be optional.
