actually they're slower than a vette handle worse than other cars in the same price range and make hp from RPMs not torque.
It's pretty much the opposite of a muscle car.
I don't know where you got that impression.

2008 Chevy Corvette Z06 Version (regular Vette significantly slower)
The new Z06 arrived as a 2006 model in the third quarter of 2005. It has a 7.0 L (7,008 cc/427.6 in³) version of the small block engine codenamed LS7. Officially certified output is
505 hp (377 kW). Its performance is significantly better than the Ford Mustang and comparable to the Dodge Viper SRT-10. Official performance figures indicate that the Z06 can reach 60 mph (97 km/h) in just 3.8 seconds from a standing start in first gear, hitting 0 - 100 in about 7.8 - 8.2, with a
quarter mile time of 11.7 and a top speed of 197 mph (electronically limited).
They are very close in performance with the Viper having a slight edge in speed and power although the Vette handles better (as you said). Enthusiasts pretty much agree that the Vette is better mannered while the Viper performs by simple brute force. I've driven an '04 Viper and, IMO, it is brutal.
