The ZL1 features a supercharged LT4 6.2L V-8 Small Block engine, with intake and exhaust systems tailored for Camaro. It is rated at an estimated 640 horsepower (477 kW) and 640 lb-ft of torque (868 Nm), backed by a standard six-speed manual transmission or all-new, available paddle-shift 10-speed automatic.

It enables the LT4 engine to remain at optimal rpm levels during acceleration, particularly when exiting corners, for quicker laps and lightning-quick responses on both up- and down-shifts.
