Dodge released last week a video of the Viper ACR-X SRT10 lapping the Nurburgring Nordschleife in just 7 minutes and 3 seconds. Unfortunately, Dodge did not disclose the name of the driver who accomplished this. The Dodge Viper SRT10 ACR-X hides under its reptile skin an 8.4 liter V10 engine, which sends 640 mad horsepowers to its rear wheels. This is 40 hp more than the standard supercar, and enough to make it conquer the Green Hell in just 7:03 minutes.
