The announcement marks the first time the US manufacturer has officially recognised the new model exists.
Switching away from a front-engined layout for the first time in the car's 66-year history, a video (below) showed the Porsche 911 rival being driven hard at the Nürburgring, revealing the expected V8 soundtrack.
Prototypes of the C8 Corvette, showing the distinctive long rear deck and cab-forward proportions indicative of a mid-engine model, have been circling for some time. Reports from the US suggest there have been delays in development owing to significant issues with the chassis and electrical architecture.
While it's not clear yet if those technical problems have been overcome, a Corvette dealer in New Jersey was taking $1000 deposits for the new model, even before the reveal date confirmation.
In a further break with tradition, the C8 Corvette will be sold alongside a version of the current car. Sources inside General Motors, which owns the Chevrolet brand, indicate that we can expect a slightly revised version of the existing C7 as an entry-level alternative. Although the C8 will carry a price premium over its front-engined sibling, it will be sold at a price that significantly undercuts the junior supercars offered by other manufacturers.
There will be no surprise in the choice of launch powerplant, with the C8 set to reach the market using a developed version of General Motors' current LT-spec 6.2-litre V8. Although this engine still uses pushrods, and will be unable to match the low-down torque of turbocharged alternatives, the all-alloy unit has many virtues: it is light, responsive, relatively cheap to build and able to generate around 500bhp with minimal work.
