The engine code for the 2024 Corvette Z06’s V8 is LT6.
The LT6 is a naturally aspirated 5.5-liter V8 with dual overhead camshafts and a flat-plane crankshaft. Its architecture differs sharply from the pushrod, cross-plane V8 used in the regular C8 Stingray. The engine produces 670 horsepower and reaches an 8,600-rpm redline.
Although the Z06 debuted for the 2023 model year, 2024 cars use the same LT6 powertrain. Chevrolet developed the engine with lessons from the Corvette C8.R racing program, including its high-revving design and dry-sump lubrication system. The result made the Z06 one of the most distinctive American production V8s.
A common mix-up is the LT2, which powers the standard C8 Stingray and the gasoline engine in the E-Ray. The later C8 ZR1 uses a twin-turbocharged derivative called the LT7, while the Z06’s defining engine remains the naturally aspirated LT6.
