No, the 2019 C7 Corvette ZR1 does not feature a DOHC V8 engine as once rumored, though it’s unclear where such plans stand at GM. That’s a different discussion.
Instead, Chevrolet revealed the most powerful Corvette ever with a 6.2-liter supercharged LT5 V8 engine, which invokes the original C4 Corvette ZR-1‘s DOHC V8 engine. The destination returns only in name, not in packaging. But, what makes the LT5 different from the LT4? Two major things.
Foremost, the 6.2-liter LT5 V8 features a larger supercharger with 52 percent greater displacement over the LT4 V8’s supercharger. More boost means more power, and the 2019 Corvette ZR1 isn’t short on horsepower at 755 hp. Secondly, GM’s first-ever dual-fuel-injection system surfaces with the new LT5 V8 engine. The system employs direct injection as a primary and port injection as a supplementary method.
We’ll have to wait for the full debrief on the LT5 engine, but it’s certainly not just an LT4 by another name.
