America does horsepower, it even does handling, but aside from the Corvette ZR1, it doesn't really do supercars--at least not in the modern sense of the word. But there are a few special cars out there, like the awesome 2010 Dodge Viper SRT10 ACR, which has apparently set the unofficial production car lap record at Mazda Raceway Laguna Seca in California.
After six hot laps around the circuit, Chris Winkler, an SRT vehicle dynamics engineer, posted a blistering time of 1m 33.915s on his seventh lap (recorded by a Motech in-vehicle data recorder). This beats the previous record, held by the Devon GTX supercar, by more than a second, which is quite impressive given the relatively short track length of Laguna Seca.
Powered by an 8.4-liter, V-10 engine with 600 horsepower and 560 pound-feet of torque, the Dodge Viper SRT10 ACR continues to offer extreme performance, including 0-60 mph acceleration in less than 4 seconds, a quarter-mile time in the mid 11-second range and 0-100-0 mph in 11 seconds flat.
The Devon GTX, incidentally, shares much in common with the Viper so it’s not surprising that the ACR, the fastest of the Vipers, is capable of such short Laguna Seca track times.
