Hats off to the vette, the viper performed as well..REMEMBER this is a viper that has not changed since 2002 and is running on slippery run flats that are like cinder blocks for forgiveness..NOTHING is gonna come close to the vette and 08 viper.. American muscle may rule after all..Maybe that's why vette guys are starting to wave at me in the viper...

quote...The Dodge Viper SRT10 coupe’s 3:01.6 lap — only a half-second behind the 277-pound-lighter Z06 — was surprisingly quick. The Viper was easy to drive fast — almost too easy, because it felt a little soulless at first. The engine sounded flatulent, the shifter was clunky, and the Dodge wanted to understeer everywhere. But when we leaned on it hard, it came alive: The steering weighted up, and we dialed out the understeer with gobs of V-10 torque. But the most amazing thing was that despite 510 horses and 535 pound-feet of torque, it took serious wrangling to get the tail out — and when we did, the slide was progressive and neat. Through the uphill esses the car was awesome, the most planted and confidence inspiring of the bunch.

The Corvette Z06, in contrast, was brutal and tricky to drive at the limit. With the stability- and traction-control systems off, it loved sideways action, whether the driver lifted at the entrance to a corner or was flooring it out the exit. The Z06 had serious brakes, talkative steering, and the most compelling engine note, but driving it fast was spooky, if oversteer makes you nervous. Mastering this car was challenging and satisfying, but drivers needed to be on their game. Still, with a lap of 3:01.1, it was the fastest of the LL3s and awfully close to taking overall honors.
