2009 Chevrolet Corvette RT Performance

638 horsepower was unleashed , VIDEO OF ZR-1 ON GERMANYS WORLD FAMOUS , NURBURGRING TESTING TRACK, , http:--www.youtube.com-watch?v=2ikj90_Un0o, , As expected, the supercharged LS9 superbly blends the Z06s raucous LS7 with the smoothness of the modern LS3. At idle there is only a hushed V-8 warble, yet get to 3000 rpm with intent and a pleasant snarl emanates. Knowing that there is an extra 133 horsepower on tap, beyond the already terror-instilling Z06s 505, I worked my way up to applying full throttle. Surprisingly, the ZR1 is far superior to the Z06 in driveability, refinement and speed. , , Everything griped about in the Z06 — aside from the unsupportive seats — has been remedied. The twitchy rear end is gone, thanks to Magnetic Ride Control that allows for softer springs and heavier anti-roll bars. The ZR1 confidence and road-holding abilities are there simply awesome.
