General Motors’ dire straits have placed more than a few of its coolest proposed cars in a tenuous limbo, including a resurrection of the top-dog Chevrolet Camaro, the Z28. Until Chevy (or Uncle Sam, perhaps) makes up its mind about the Z28 from a business standpoint, Hennessey Performance Engineering of Sealy, Texas, has a rather potent stand-in: the 2010 HPE550 Camaro, which has already begun production.
Starting with the $31,040 Camaro SS with the 426-hp, 6.2-liter V-8 and six-speed manual transmission, the HPE550 adds a Magnuson/Hennessey supercharger system with 6 psi of boost, as well as a Corsa stainless-steel exhaust system and custom engine-management calibration. Together, those simple mods raise total output to 562 hp and 557 tire-peeling lb-ft of torque. Hennessey can also install the supercharger on the Camaro SS with the 400-hp, 6.2-liter V-8 and six-speed automatic transmission, although output would be somewhat less. But hell, even if it was 10 percent less—which it wouldn’t be—you’d still end up with a 500-plus-hp Camaro.
