A self-styled “insider” has leaked some top secret information on GM’s upcoming mid-engined Corvette.

Before we get to the exciting details on this latest leak, first we must post the big disclaimer that this should all be taken with a huge grain of salt. The post is over on CorvetteForum.com (which we are alerted to by way of Motor1) and is from an anonymous person who has recently created their account for the sole purpose of creating this singular post.

They also have the name “unlimitedPower”, which just sounds ridiculous.

With that out of the way, on to the goods. Mr. or Mrs. or Ms. “unlimtedPower” says that the new C8 will be called the Manta Ray, in keeping with the naming convention of the C7 Stingray. It’ll have a modified version of the same LT1 V8 that powers the current C7 Corvette, but tuned to produce 520 hp. Not a bad place to start.

But that’s not all! Two years after the base-level Manta Ray is released will see two more C8 Corvettes arrive. The first will be a luxury-focused model called the Grand Tour. It’ll use Cadillac’s 4.2-L twin-turbo V8 and a host of sound-deadening features to make the Grand Tour the smoothest, quietest ride that GM has ever created.

It also moves the turbochargers to the sides rather than between the stacks. Nobody is quite certain why, but it probably has to do with making it the quietest V8 they can.

The second will be called the Grand Sport, and it’ll be powered by a “frighteningly powerful” 5.5-L twin-turbo V8 that can dominate “both 'the Germans and Italians.'" We’re guessing our insider is using quotations to cover up some ethnic slurs.

Here’s where things get weird. Our insider says that this engine “is literally frightening to floor it,” and that “GM even had a team of lawyers in to advise on the legal perils of selling such a potent vehicle for street use.”

C’mon. We live in a world with 8.0-L W16 engines. Some electric hypercars are pushing 2,000 hp and reaching from zero to sixty in less than 2 seconds. It’s hard to believe a 5.5-L twin-turbo V8 can be more frightening than that.

So this could all just be drivel spouted by a Corvette dreamer, or even a publicity stunt. Take this where you will.

Some more believable notes are that Corvette will become a “brand unto itself” where only authorized techs and dealers can sell it, and that the Camaro will occupy the same market segment that the old C7 Corvette used to enjoy. We’ll have to wait and see, but we can see it.
