...thanks to a twin-turbocharged 5.5-liter flat-plane V8. There's a lot more to it than the big numbers, though. Luckily, we got to talk to several of the lead engineers behind the car, including its executive chief engineer, Tadge Juechter.

The Z06's LT6 engine and the ZR1's LT7 are closely related, and some parts on the LT6 are clearly made to accommodate the ZR1's turbocharging system. The dry sump oil tank, for instance, is common between the two engines; However, it's sculpted to avoid turbocharger plumbing. Since the Z06 debuted first, this detail and others have been hiding in plain sight the entire time.

All of these details and more—like hints of an even more powerful Corvette—were part of a great discussion with the Corvette team while they whisked Peter around a full-sized cutaway of a ZR1. And before you watch, yes, he forgot to take off his backpack for the entire thing. Sorry.

The 2025 Chevrolet Corvette ZR1 is the most powerful V-8 American production car ever. It has a twin-turbocharged 5.5-liter flat-plane-crank V-8 with 1,064 horsepower, 828 pound-feet of torque, and an 8,000-RPM redline. For more ZR1 content, see the links below:
