Mid-Engine Chevy Corvette launch at a track.

The mid-engined C8 Chevrolet Corvettehas just been spotted testing at the track, giving the latest glimpse of the GM'splanned halo model. The supercar is expected to debut in 2019 and to add to the current Corvette model rather than to replace it directly; it is expected that GM will keep both in production until 2022, when the current C7-generation Corvettewill complete its model cycle.
In the video, the car stops several times before performing a track launch, with a tiny bit of wheel chirp.

We see the LED turn signals flash, too, underneath the bodywork. They have a squared off aspect, much like the C7 lights we're used to now.

This mid-engined version of the Corvette, which has been in development for several years, may be using a twin-turbocharged 4.2-liter V8 currently making its way through the GM pipeline, but it may also be using a 6.2-liter LT1 V8 engine, which is also expected to appear in the lineup. The sound in this video sounds more like a naturally-aspirated V8 rather than a turbocharged one due to the absence of hisses and whooshes from turbochargers as the engineers give it a lively start. The sound in the video also gives a clue as to the transmission paired with the engine; this one seems to be a dual-clutch unit, which is not terribly surprising given the car being tested and what we already know. In fact, a three-pedal C8 is not expected to be on the menu at all, as GM and Tremec have reportedly been working on an eight-speed DCT. When it lands in 2019, likely as a 2020 model, the C8 Corvette may end up offering a choice of three powerplants in addition to a battery-electric version or a plug-in hybrid. A 6.2-liter V8 is expected to be the base engine with around 500 hp on tap, while the twin-turbo 4.2-liter V8 may end up being the mid-level powerplant with approximately 650 hp.
