The battle between America's preeminent supercars continues as Inside Line has taken a stock Dodge Viper ACR to the Bonneville Salt Flats to see what it can do. We'd say it did rather well. On the final run of the day, Dodge's ultimate Viper slithered its way to 173 miles per hour on the 10-mile long strip of salt. There's a great story about what it took to reach that terminal velocity, click here to read it.
By way of comparison – and because we know you're all wondering – Top Gear's Jeremy Clarkson was able to wring a stock Corvette ZR1's neck to about 176 miles per hour at Bonneville in an episode that aired late last year. Different days with different weather conditions to be sure (update: as pointed out in the comments, the ZR1's figure was achieved with just 1 mile of runway), but it's always fun to stir the pot, right?
It's not just in straight-line acceleration where the two American heavyweights duke it out, with the Viper ACR recording a blistering lap of the Nurburgring in just 7:22.1, which compares rather favorably to the ZR1's 7:26. Strapped to the dyno, the Viper ACR puts down a whopping 546 horsepower and 510 lb-ft of torque compared to the supercharged ZR1's 549.9 horsepower and 500 lb-ft. Now, when does round 4 begin?
