A black and red 2010 Dodge Viper SRT10 ACR (American Club Racer) led by Chris Winkler, an SRT vehicle dynamics engineer, recorder a new lap record 1:33.915 at Laguna Seca.
“It was definitely exciting but a somewhat uneventful lap overall from behind the steering wheel,” said Winkler, who is still learning the intricate details of Laguna Seca raceway, having spent only one other session on the course. “The Dodge Viper ACR has amazing power and handles like a dream, so following my first practice here last month, I came away pretty confident that we’d be able to set a new record.”
In 2008, professional road racer Randy Pobst, drove a 2008 Dodge Viper ACR to a one-lap, production car record of 1:35.117 at Laguna Seca raceway while working with Motor Trend. That record stood until August 6, 2009 when the most recent record of 1:35.075 was established by a one-off exotic prototype.
With such record, the Dodge Viper ACR remains the ultimate purpose-built, street-legal track car since its introduction in 2008.
New for the 2010 model year is a shorter fifth gear ratio (changing from 0.74 to 0.80) for improved high-speed acceleration and higher straightaway speeds. This improvement is a direct result of SRT’s experience at the 12.9-mile Nurburgring Nordschleife circuit in Germany where during the lap-record run in 2008, it was found that a revised gear ratio would have resulted in a higher speed capability and potentially a shorter elapsed time.
The Dodge Viper ACR also receives a new short-throw shifter in 2010 for enhanced driver experience and better performance. The rear wing profile and end plates are redesigned to further optimize the vehicle aerodynamics and improve rear yaw downforce. These changes result in an increase in top speed of 4 mph (to 184 mph).
Powered by the venerable 8.4-liter, V-10 engine with 600 horsepower and 560 lb.-ft. of torque, the Dodge Viper ACR continues to offer extreme performance, including 0-60 mph acceleration in less than 4 seconds, quarter-mile time in the mid 11-second range and 0-100-0 mph in 11 seconds flat.
