Unveiled just this week at the Chicago Auto Show, the range-topping 2012 Camaro ZL1 promises to be the most powerful and most advanced Camaro ever produced.At the heart of this high-performance machine is a LSA 6.2-liter supercharged V-8 engine that produces an estimated 550 horsepower and 550 pound-feet of torque. Aside from being built on GM’s renowned small-block V8 architecture, this unit has technically advanced features including an intercooled supercharger system, premium heat-resistant aluminum cylinder heads and many other details. All these features are designed to ensure its exceptional performance is delivered with smoothness and refinement.
“The LSA is the ultimate engine for the ultimate Camaro,” said John Rydzewski, assistant chief engineer for small-block engines. “It has a broad power band that matches the Camaro ZL1’s performance capabilities at every notch on the tachometer.”
The powerful LSA engine can also be found in the Cadillac CTS-V. However, the Camaro’s engine has many unique components that differentiate it from the Cadillac application, such as:
* Black intercooler housing with unique heat exchanger and plumbing to accommodate the Camaro engine compartment
* Cast stainless steel exhaust manifolds for enhanced thermal management
* Camaro-specific oil pan
* Revised accessory drive with unique alternator and air conditioning compressor
* Idler pulley in place of the conventional power steering pump pulley, because of the use of electric power steering
* Special engine cover in red.
An Eaton supercharger complements this engine by helping the LSA deliver a broad range of power through the rpm band, giving the engine great low-end torque and excellent horsepower at higher rpm.
“The design of the supercharger’s rotating internal components extends its effective range, giving the engine a wide, flat power band that is usable at all rpm levels,” said Rydzewski, assistant chief engineer. “Whether at low speeds or on the highway, the feeling of power is instant, strong and sustained.”
GM is still putting the final touches on this model, but the ZL1 should arrive in showrooms early next year.
