Chevy Camaro ZL1 Rated At 580-HP

Back when the 2012 Chevy Camaro ZL1 was unveiled at the Chicago Auto Show, Chevy said that it produced an "estimated" 550 horses from its 6.2-liter supercharged LSA engine. When we heard that little caveat, we assumed that it was going to be slightly lower, since we figured Chevy would want to project the highest output possible. But, between then and now, something else happened: rumors about the 2013 Mustang Shelby GT500 offering around 600 horses hit the interwaves, and Chevy decided to move that "estimated" figure right on up the scale. 

The Camaro ZL1 recalls the 1969 engine of the same name and will be the most powerful Camaro ever. Its 580 hp will come at 6,000 rpm, and its 556 lb-ft of torque will come at 4,500 rpm. The LSA engine offers 24 horses and 5 lb-ft over its Cadillac CTS-V application. In short, the ZL1 means business.

The increase in output puts the ZL1 well over the 550-hp 2012 Mustang Shelby GT500, but is still short of the rumored 600 to 620-hp that Ford supposedly plans to equip the 2013 GT500 with. If it ends up being more toward the upper end, that would put the GT500 right between the Camaro ZL1 and the 638-hp Corvette ZR1. Not a bad place to be for Ford.

According to Chevy, the increase in horsepower comes thanks to a "a unique induction system, with a lower-restriction air filter, dual ‘bell mouth' inlet paths, and improved airflow through the supercharger housing. Other changes include a higher-efficiency supercharger intercooler and electric power steering system, which consumes less engine power than hydraulic steering systems."

More than just an unrefined pile of horsepower, the Corvette ZL1 will transfer that power nimbly with a new magnetic ride control that offers Tour and Sport modes. The system is capable of adjusting the suspension up to 1,000 times per second, to deliver a high-performance ride. Other equipment includes a five-mode Performance Traction Management system, Brembo brakes, a Tremec TR-6060 six-speed manual with twin-disc clutch and a dual-mode exhaust system. A six-speed manual transmission with three driving modes will also be offered.

No word on pricing or launch just yet.
