An all-new, mid-engined Corvette has been in the works for at least five years now and must have been one of the worst guarded secrets in the automotive industry.

Meanwhile, another GM brand, Cadillac, recently added a twin-turbo 4.2-liter V8 to its family. One may think the General would want to fit this engine into theVette, but that doesn’t seem to be even remotely on the cards. At least not now.

From the moment it launched its Blackwing engine, the company insisted it would remain a Cadillac-exclusive powertrain. While recently speaking with Muscle Cars & Trucks, GM president Mark Reuss added that the Corvette development team hasn’t even tried fitting the Blackwing V8 into the C8.

“We can do anything with enough time and money, but we’re not sure we want to do (that) because it’s Cadillac exclusive,” Reuss said at a recent Cadillac event.

While the Blackwing won’t find its way into the new Corvette in its current form, it is likely that a derivative of this engine will form the basis for future ‘Vette mills, as it is claimed that GM has given Chevrolet the go-ahead to develop more powerful versions of the Blackwing architecture.

Each engine is assembled by hand at the same Bowling Green plant as the engines powering the Corvette, and if we were to guess, we’d suggest that the long-rumored twin-turbo 5.0-liter V8 which will eventually power higher-end versions of the C8 could use much of the of the Blackwing structure, but with greater displacement and different internals.

Power details about this potential engine are unclear, but it would likely be the powertrain of choice for the rumored hybrid ‘Vette with upwards of 1,000 HP. Of course, that is mere speculation right now, but if the bean counters decide it makes sense, and the powers-that-be reverse course on the “Caddy-exclusive” mandate, it would seem like the logical thing to do.
