The most important question for Chevrolet Camaro fans for the past year has been how many ponies the reborn ZL1 will be able to put down. Originally, the beast was rated at 550 hp and 550 lb-ft (677 Nm) of torque coming from a LSA 6.2-liter supercharged mill, which is the most explosive mix of all-aluminum small block, an intercoolded efficient supercharger and heat-resistant aluminum-alloy cylinder heads.
Yet Chevy’s engineers don’t want their brute that’s a reincarnation of a rare 1969 model to be anything less than impressive. Yesterday, they revealed that the ZL1 will take on the mighty Ford Mustang Shelby GT500 with no less than 580 horsepower coming from the 6.2-liter aluminum mill. All the horses are unleashed from the engine at 6,000 rpm, while the torque remains about the same 556 lb-ft of torque at 4,200 rpm.
The Camaro gurus say the improved figures come from “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,” according to Auto Week, who was present at the media event.
We still don’t know how much the beast will cost, although $50,000 is a good estimate, give the sticker of the Ford competitor. Look for the ZL1 to show its muscle power at the upcoming 2011 Los Angeles Auto Show in November.
