Saleen’s (the man, not the company eluded to above) reputation should be cemented further with the SMS 620 Camaro. The 620’s engine is alleged to give 575 hp. If this is a little weak for your tastes, you can get 715 horses if you make the leap to the 620X version. I guess the 620X could be classified as a superdupercar.  You can get yourself either version in mid-2010. And, if you can’t buy one, hopefully you’ll get the pleasure of feeling the breeze of one of these babies blowing by on a highway near you.

The HPE550 - a 562hp beast

Texas-based Hennessey Performance Engineering is giving the 2010 Camaro a shot in the arm – and the shot it pure juice.

The 2010 Hennessey HPE550 Chevrolet Camaro adds a Magnuson/Hennessey supercharger to the already powerful base Camaro SS – the result, a 136hp boost. The HPE550 boasts an incredible 562hp with 557lb-ft of torque. According to Hennesy, the HPE550 can hit 60mph in 4.1 seconds – .7s faster than the production SS.

A diy version of the HPE550 will run you around $47K, a turnkey version warranted by Hennessey for 3 years/36,000 miles starts at $59K.
