A twin-turbocharged 2006 Dodge Viper has set a new world record-setting the fastest top speed ever recorded by a Viper, hitting 252.588 mph (406.501 km/h).
The car, recently tested at the Johnny Bohmer Proving Grounds, has undergone a host of modifications that have lifted power from its V10 engine to roughly 1,400 hp. It is also rolling on a set of experimental tires that played a key role in the record run.

This onboard video of the record-setting run shows the Viper getting off the line very slowly as the driver aimed to minimize wheel spin. Up until 100 mph (160 km/h), the driver slowly changes through the gears before really hitting the throttle. It takes the twin-turbo Viper roughly 10-seconds to go from 100 mph to 200 mph (320 km/h) and from there, the speedometer just keeps on climbing until the driver let off the throttle after passing the 2.7-mile marker on the runway.
Towards the end of the run, the ride did seem to get a little bumpy but other than that, it doesn’t seem as though the car was struggling all that much at such incredible speeds. A top speed of 252 mph is just 1 mph behind the vmax of the original Bugatti Veyron, once the world’s fastest production car.
