LT2: years, specs & known problems
By CarWhere Research · Updated
The LT2 is the 6.2-liter Gen V small-block V8 mounted behind the driver in the C8 Corvette Stingray since the 2020 model year. It is rated at 490 hp and 465 lb-ft, or 495 hp and 470 lb-ft with the performance exhaust. Unlike the LT1, it uses a dry-sump oiling system as standard.
Chevrolet developed the LT2 for the mid-engine 2020 Corvette Stingray. It keeps the Gen V 6.2-liter bore and stroke, an aluminum block, direct injection, Active Fuel Management and an 11.5:1 compression ratio, but adds a standard dry-sump lubrication system with piston-cooling oil jets so the engine can sit low in the chassis and stay oiled under high cornering loads. It is paired with an eight-speed dual-clutch transmission.
Output has been 490 hp in base form and 495 hp with the performance exhaust since launch. The LT2 has no engine-specific NHTSA safety recall as of November 2026. Owners should follow the 0W-40 dexos2 oil specification and the dry-sump oil-level check procedure in the owner's manual.
