The ZL1 packs a more powerful version of the supercharged 6.2-liter LSA V8 that was introduced in the Cadillac CTS-V. In the Camaro, the motor is good for 580 horsepower and 556 lb-ft of torque, beating out the classic 1969 ZL1's 427 cubic inch V8 by more than 150 horsepower. Helping make those impressive power figures is a 1.9-liter Roots-style supercharger that crams air into the engine with a pair of four-lobe rotors and the aid of an intercooler.
Chevrolet modified the LSA engine specifically for the ZL1, with upgrades including a less restrictive air filter, dual inlet paths and improved airflow throughout the supercharger housing. Other changes include a more efficient intercooler and electric power steering system.

More About Camaro ZL1
Specially engineered transmissions were necessary to the stress of all that power. Chevy beefed up its Tremec TR-6060 six-speed manual to MG9-spec for ZL1 duty, which means the transmission can handle 30 percent more torque. This is achieved through the use of a strengthened output shaft, high-strength rear housing and additional roller bearing.
One unique feature of the ZL1 among high-performance muscle cars is the availability of an automatic transmission. While the notion of adding an automatic transmission may make some enthusiasts cringe, the reality is some consumers with pockets deep enough to purchase this car may very well prefer a six-speed automatic transmission over a do-it-yourself box.
