The SRT Viper ACR-X has been flexing its muscles around Nurbugring and they have been good enough to release a video of the run. It shows the race car achieve a lap tome of 7:03.058 around the Green Hell and also gives a little extra information including real-time stats for the downforce and g-force.
The time is only a little quicker than the Viper ACR production version that completed the same lap in 7:12.13 back in September last year. On that occasion, the Viper ACR retook the production car lap record around Nurburgring from the Corvette ZR1.
The Viper ACR-X is powered by an 8.4-liter V10 engine that produces 640 horsepower (40 hp more than the standard model) and has a number of performance tweaks. These include a specially-tuned sports suspension, improved aerodynamics and a complete safety package (with a roll cage, fuel cell and race seat).

The key differences between the street legal Viper ACR and the Viper ACR-X shown in the video below are an engine tune that increases the power to 650 horsepower with help of exhaust headers and a high flow exhaust system, a stripped out interior complete with a race seat and roll cage and a track tuned suspension setup that works with the racing slick tires. According to Wikipedia, the only vehicles to lap the Nurburgrign in less time than the Viper ACR-X are the Radical SR8 LM, the Radical SR8, the Pagani Zonda R and the Ferrari 599XX.
The video below, courtesy of the folks at the Viper Club of America, shows the 2010 Viper ACR-X ripping around every turn of the Nürburgring, including a timer G Force meter and gear indicator in the lower left side and a downforce gauge along the top. Unfortunately, unlike the videos of the Chevrolet Corvette ZR1 and Z06 on The Ring, there is no speedometer on the video but we can bet that the Viper gets awfully near (if not faster than) 200 miles per hour on the long ending straightaway. The downforce gauge is interesting to watch as the Viper ACR-X roars down the long straightaway – with the aerodynamics package on the ACR-X creating over 1370lbs of downforce towards the end of the long stretch. During the video you will also see the ACR-X pulling almost 2 full G’s in the lower left corner…another incredible accomplishment for this near-street legal car.
The next generation SRT Viper is expected to make its formal debut in early April at the New York Auto Show but over the past two weeks, the Chrysler Group has offered a pair of teasers of the new supercar (click here for the front end teaser and click here for the mystery air intake image). As we lead up to the formal debut of the 2013 Viper in New York, we can expect more hype from the SRT division in the form of goodies like the video below and we can hope (and pray, and cross our fingers) for more teasers and information ahead of the debut of the new Viper. The only tidbits of information that we know thus far on the 2013 Viper is that it will pack a high tech traction control system (likely with stability control, etc) and we can expect that it will be powered by a revised version of the Viper V10 with somewhere in the neighborhood of 650-700 horsepower.
