Dodge Viper ACR at Miller Motorsports Park - Click above for high-res image gallery

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.

Tooele, Utah - The Dodge Viper SRT10 ACR (American Club Racer) has made history at yet another storied road course.

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).

      What a barnstormer. I love that daggone car.

      Doesn't this technically run DOT approved slicks?

      I'd like to see the other vehicles run these exact same tires and redo their laptimes. It isn't really an apples to apples comparison until that is done. There is a HUGE difference between track tires and a summer street tire.

        @ trustedcarsalesman

        Yes, I know.

        Those are DOT approved competition tires.
        • 3 Years Ago
        Since when?
        The ZR1 and Z06/7 run Michelin Pilot Sport PS2's which may sound like the same tire as a Cup; but you're talking about a 25,000 mile treadlife PS2 tire VS a 3,000 mile treadlife Cup tire.

        Absolutely right. But it is *very* difficult to have an apples to apples comparison. Just ensuring the tires are all the same is difficult, let alone same driver, same weather, same track conditions, etc., etc. But certainly it would be very interesting (and enlightening) to see a comparison with as few as possible changing variables.
        • 3 Years Ago
        I understand what you are saying.

        It just would be interesting if all of the other vehicles wore the same brand with the same compound and re-tested. You can't control all of the variables, but all vehicles running on the same tires will definitely make the outcome more interesting.

      Still Kicking ass.. and taking names!!

      I like every single version of the Viper ACR. And considering the ACR respectfully beat the ZR1 on the Nurburgring by the same amount time (Around 4secs), it makes me wonder how much the ZR1 would beat the viper by with an agressive aerodynamic and track-prepped interior package......
        • 3 Years Ago
        There's really no shame in a street car (ZR1) losing to a track car (ACR). You can technically drive the ACR on the road, but good god you wouldn't want to.
        • 3 Years Ago
        The world is full of what-ifs. What would happen if the Viper had a blower like the ZR1 has? Chrysler chose to build a track monster, GM didn't, get over it.

        • 3 Years Ago
        Chevy had the ZR1 to Nurburgring once in 2008, and hasn't been back since, do you have any links to show any other testing?
        • 3 Years Ago
        Just like I wonder what would happen if dodge put a blower on on the viper or had three different engine options or if the viper was as extensively tested on nurburgring like the vette was. see allen has a point. the world is full of what ifs, get over it.
        btw, viper doesn't have a 'track prepped' interior, unless you're thinking of the acr-x over the standard acr but the x isn't street legal. but acr to stock they are the same

      Would love for them to redo the Viper in 3/4 scale, with a proper 6.2L Hemi...

      and then a twin-turbo version
      • 3 Years Ago
      That damn ole ugly sounding sombitch is one bad ass automobile !!!
      Kick's every body's ass ! All comer's.
      • 3 Years Ago
      Nice camera on the front.
      • 3 Years Ago
      In before "this isn't in production anymore"...
      • 3 Years Ago
      So cool. God I hope they don't mess up the next viper. Stick to the tradition. BIG v10 up front, please no turbo six. Hell with all the eco nerds I wouldn't be surprised to find a 4 cylinder version. Love the vipers!
