With the CT6 being displaced by the Hummer, Cadillac's twin-turbocharged Blackwing V8 has no home. And sadly, that's not about to change.

Speaking to Road & Track, Cadillac President Steve Carlisle said that the overhead cam V8 won't be under any hoods any time soon.

"[We have] no specific plans for that engine, but never is a long time," said Carlisle.

The Blackwing V8 supplied the CT6-V with 550 hp and 640 lb-ft of torque but reportedly didn't fit into Cadillac's smaller sedans. Rumors suggest that the highest-power edition CT5-V will instead get the same 6.2-liter small-block that did a pretty great job in the CTS-V.

Fortunately, the Blackwing name may stick around after the engine is gone, whenever it does officially die.

"We learned a lot with Blackwing. It's an idea that's really resonated with people," he said. "So there'll be a little bit of Blackwing in other cars going forward."

The Blackwing spirit may not always be applied to V8s. In fact, it may not even be strictly connected to internal combustion. With Cadillac's focus for the more distant future squarely pointed at electric vehicles, performance vehicles may continue the V tradition.

"High-performance electric cars are very much a possibility," said Carlisle.
