We've also heard rumors that the midengine Corvette will be called Manta Ray (the current, seventh-generation Corvette coupe is called Stingray). As for exactly what engine will reside amidships, that's still unknown, but rumors have suggested a 520-horsepower V8 will be on offer.
In addition to the photo released on Twitter, Chevrolet published a handful of teaser images on the Corvette Instagram page. Chevy also distributed a handful of photos of the next-generation Corvette prototype being driven through New York on Thursday. All of these images can be seen in the gallery below.
