Nobody outside of GM knows for sure which motor will power the highly anticipated C8 Corvette, set to roar into the public’s eyes without its camo next Thursday.
But we apparently do know for sure it won’t be the 4.2-liter double overhead cam LTA V8 engine, nicknamed Blackwing, that is making its debut in the 2020 Cadillac CT6-V.
That’s straight from the man at the top, GM President Mark Reuss.
Muscle Cars & Trucks reported this week that Reuss indeed has confirmed the Blackwing engine will be strictly for Cadillac.
“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 of stuffing the Blackwing into the C8.
That doesn’t mean a derivative of the Blackwing engine – which in its current form produces 550 horsepower and 627 lb-ft of torque for the CT6-V – might not eventually show up in one of the higher-output C8 Corvettes expected to debut at some point in the mid-engine’s development.
Since the LTA engine is being hand-assembled at Bowling Green’s assembly plant where the C8 Corvette will be put together, it would definitely be convenient for an eventual Blackwing family member to be used in a C8. It’s long been rumored that a twin-turbo derivative (a 5.5-liter DOHC flat-plane crank V8) could produce a whopping 800 horsepower, though it’s unlikely Chevy will spill the beans about any of that at next week’s unveiling of the C8 in California.
For now, however, it appears based on speculation (again since no official word from GM has been heard) that the new base model Corvette will use a small block pushrod V8 believed to be named LT2, similar to the 6.2-liter LT1 currently used in the C7 Corvette and Camaro SS but with higher output that could climb above 500 horsepower.
We’ll find out for sure next Thursday night.
