“Not bad” is the first thing I could say about the new Corvette ZR1. They called it the American supercar and for a reason because it was supposed to output 620 hp from a hand built LS9 6.2L supercharged V8 engine. Though 620 hp may have been enough, it turned out to be the bad number, because Corvette ZR-1 outputs nothing less than 638 hp (476 kW). This is the most powerful engine that GM ever built.

“The combination of large displacement and the new, four-rotor design broadens the effective range of the supercharger, allowing the engine to make more power at lower rpm and sustain it throughout the power band. The low-end torque is tremendous and the high-rpm charge from the supercharger is simply amazing.” said Sam Winegarden, GM Powertrain Chief Engineer.

Chevrolet is going to build only 2000 units / year an only 50 will be available for Europe, so I really don’t know if you’ll be able to see any in South Africa they are a bit expensive $103.300.

the last article i was reading projected the price to be much higher Base will be around 105,000 but this is with out all the bells and whistles that make this car worth the price. add on a 10,000 option for the lether seats nav screen ect.. making the final price 115,000. i think its totaly worth the price for GMs first attempt at a car with the ability to move 200+MPH and plus its a vet!!! even better ha ha
