The Dodge Viper ACR is no longer in production, but it remains one of the most impressive sports cars ever built as evidenced by a recent trip to Miller Motorsports Park in Tooele, Utah. Dodge Motorsports brought a 2010 Viper ACR to the track along with road racer Kuno Wittmer, and the result was a record-smashing lap time of 1:59.995 – nearly four seconds faster than the previous record of 2:03.86 held by a Corvette ZR1 driven by Jan Magnussen.
This isn't the first time the Viper ACR has broken a track record for a production car. In 2008, Dutch driver Tom Coronel piloted a Viper ACR to a record 7:22.1 lap time around the Nürburgring, and one year later, an SRT vehicle dynamics engineer broke the Mazda Raceway Laguna Seca lap record with a time of 1:33.92.

Renowned Dodge road racer Kuno Wittmer piloted a street legal 2010 Dodge Viper ACR to a record lap of 1:59.995 at Miller Motorsports Park in Tooele, Utah, on Monday, April 11, breaking the 2-minute mark for the first time in a production car on the 3.048-mile Outer Course configuration. The Viper ACR shattered the previous production car lap record of 2:03.86, held by Jan Magnussen in a Chevrolet Corvette ZR1 by close to 4 full seconds.
"It's amazing to come to this world-class track and shatter the production car lap record by almost 4 seconds," said Bryan Viger, Head of Dodge Motorsports. "We brought our street-legal Viper ACR to see what Kuno could do behind the wheel, and on his second lap he'd already gone faster than the single lap record."
A veteran behind the wheel of the Viper on and off the track, Wittmer continues to be impressed by the performance of the Dodge Viper ACR. "Wow, what an awesome supercar!" the Montreal native said after exiting the car. "The Viper ACR is such a blast to drive at the limit, and I can honestly say that I didn't leave an inch out there on the track and was barely braking in the corners."
This latest achievement joins a growing list of track records for the Dodge Viper ACR. In November 2009, SRT vehicle dynamics engineer Chris Winkler lapped the 2.238-mile, Laguna Seca raceway in 1:33.92, beating the previous record by 1.1 seconds. Dutch driver Tom Coronel set a 7:22.1 production car record at the 12.9-mile Nurburgring Nordschleife in August 2008.
Dodge Viper ACR
The Dodge Viper ACR remains the ultimate purpose-built, street-legal track car since its introduction in 2008.
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.
The four-wheel independent suspension features high-performance aluminum control arms and knuckles, KW suspension with two-way adjustable competition coil-over shock absorbers with remote reservoirs.
The aerodynamic package features a carbon fiber "fanged" splitter in front and adjustable carbon-fiber wing with seven-position stanchions that allow up to an amazing 1,000 lbs. of downforce at 150 mph. Lightweight wheels, two-piece slotted StopTech brake rotors and Michelin PS Cup tires round out the ACR package.
For the 2010 model year, the Dodge Viper ACR received a shorter fifth gear ratio (changing from 0.74 to 0.80) for improved high-speed acceleration and higher straightaway speeds. A new short-throw shifter also came in 2010 models for enhanced driver experience and better performance. The rear wing profile and end plates were also redesigned to further optimize the vehicle aerodynamics and improve rear yaw downforce. These changes resulted in an increase in top speed of 4 mph (to 184 mph).
