While we anxiously await the new SRT Viper to finally make its debut at the upcoming New York International Auto Show, it appears that Dodge wants to remind us just how powerful its previous iteration of the Viper was.

The Viper Club of America has released a new video showcasing the race-only Viper ACR-X taking on the Nürburgring with a lap time of 7:03.058, which is almost 10 seconds faster than the street-legal Viper ACR, which depending on who you ask is the current production car record holder.

For a race-only production car, the ACR-X has an impressive time, but it’s no the fastest – not even close. Depending on how obscure you prefer your exotic cars, the Ferrari 599XX managed a 6:58, the Radical SR8LM has posted a 6:48 lap time in the past and the Pagani Zonda R tops them all with a blistering 6:47 time.

This coming Sunday, October 9th, a very special event will air on Versus at 3 pm Eastern Time. It’s the Duel in the Desert, a special edition of the Viper Cup race series, where a talented collection of drivers and motorsports heros, from all different forms of the genre, race against each other at Miller Motorsports Park, in Toole, Utah.

The race, actually run back in April, features such legends as Roger Penske, Jeff Gordon, Robbie Gordon, Sam Hubinette, Kurt Busch, Kuno Wittmer, Allen Johnson and Ralph Gilles to name a few.

Each of the 24 drivers competed in identically prepped Dodge Viper ACR-X coupes, and were split into two person teams, with single qualifying lap times from each averaged together in order to determine starting positions on the grid for the race.

Timed for just 50 minutes, the actual event required each team to make a pit stop and change drivers halfway through, making for some very exciting racing.

Besides competing, the celebrity drivers were also racing for a cause, with money donated by the top three finishing teams, to several charities, including the Haiti Rescue Effort, National Breast Cancer Coalition, Shriners Hospital, Tarrant Area Food Bank (Ft. Worth, Texas), Children’s Rare Disease Network and the National Breast Cancer Foundation.

“I can’t say enough about the generosity and mutual respect shown by each and every participant in the ‘Dodge Viper Celebrity Challenge,’ Ralph Gilles, president and CEO of Chrysler’s SRT Group and Dodge Motorsports. “I’m proud to share the same common thread of being racers at heart that can take the time out to not only come together and compete on the same stage, but also raise money for worthy charity causes.”

Just a week after Lexus confirmed its LFA Nurburgring Edition had set a new lap record on the Green Hell, Dodge has one-upped the Japanese automaker. With a 7:12 time, the now out of production ACR’s time is a solid two seconds ahead of the $400,000 LFA supercar.

With a 32-hp advantage on the LFA, the Viper ACR’s real strong points are excessive amounts of torque and a nearly absurd spoiler that provides race car like downforce at speed.

In addition to this news, Dodge also reportedly ran a Viper ACR-X track car on the ‘Ring, lapping almost 10 seconds faster than the standard car with a 7:03 run.

Dodge head honcho Ralph Gilles took a brand new Viper ACR-X around Virginia International Raceway not long ago, and decided to film his exploits.

With Powertrain Communications Manager Nick Cappa as his passenger/videographer, Gilles managed to hit a peak speed of 165 mph and turn a 1 minute, 35 second lap time. The ACR-X sheds 160 pounds and gains 40 horsepower over the “normal” ACR (for a total of 640 horsepower), making it one seriously quick machine.

Dodge has announced that the inaugural season of its Viper Cup Series will air on the VERSUS specialty cable network. The series kicks off  at Virginia International Raceway (VIR) on July 10-11, with that race airing on July 24th.

Each race weekend will feature two races, with the ten-race spec series moving to tracks like Pocono, Miller Motorsports Park and Spring Mountain.

Used exclusively in the Viper Cup Series is the new Viper ACR-X with a 640-hp 8.4-liter V10 engine, combined with a track-tuned suspension, a curb weight that has been cut by 160 lbs and several aerodynamic enhancements. A roll cage, fuel cell and race seats complete the package for racing in the SCCA and NASA Viper Racing League.

“The Dodge Viper ACR-X is designed and built specifically for the race track,” said Ralph Gilles, President and CEO, Dodge Brand. “Now with VERSUS on board, race fans will have the opportunity to see our untamed and unmatched road-racing machine along with some of our talented Viper owner/drivers compete on five of the best road courses in the county as part of the Dodge Viper Cup series.”

The 2010 Dodge Viper SRT10 ACR-X is an even more hardcore version of the street-legal ACR, the X being a track-only special edition built specifically for Viper racers who want even more power and less weight.

There is, however, one small problem. No matter how serious a Viper racer you may be and no matter how much your most recent Goldman & Sachs bonus check may have been, Dodge has already sold all 25 ACR-X examples they plan to build, so you can’t have one.

So why are we posting about the ACR-X if they’re already all spoken for? Because come on, look at the thing! It’s outrageous! Not only is it powered by a SRT-developed 8.4-liter V10 engine that’s been equipped with high performance headers and a low-restriction exhaust system for a neck-snapping 640 horsepower (40 more than the production model) and 605 ft-lbs of torque (45 more than the production model), it’s also been put on a 160 lb diet. Combine that with a suspension that’s been tuned and upgraded specifically for on-track usage with unique springs, two-way adjustable shocks and adjustable sway bar links and you’ve got one serious super snake. The ACR-X has also seen some aerodynamic revisions including quad-dive planes and underbody ducts to improve downforce while enhancing stability and significantly improving grip in high-speed cornering.

Unlike the street-legal ACR, the ACR-X includes safety equipment such as a factory-designed roll cage, fire suppression system, fuel cell and race seat. Additional racing components including a transmission cooler, rear differential cooling system, unique front rotors with larger surface area and improved brake cooling via scoops in the front fascia have also been added to meet the significant durability and reliability requirements for on-track competition.

Although it’s too late for you to buy one, if you want to see a Viper ACR-X in action, many of them have been sold to Dodge Viper Cup Series competitors. This newly developed spec racing series, which will be sanctioned by the existing Viper Racing League, has two races per weekend for five weekends. The spec part means every car racing in the Cup Series will be a Viper ACR-X, so show up at the track on any of these dates and you’ll likely see most of the 25 sold in action all at once.

  • July 9-11 at Virginia International Raceway (VIR) in Alton, Va.
  • Aug. 14-15 at Hallett Raceway in Jennings, Okla.
  • Sept. 11-12 at Pocono Raceway in Long Pond, Pa.
  • Oct. 1-3 at Miller Motorsports Park in Tooele, Utah
  • Oct. 22-24 at Spring Mountain Motorsports Ranch, in Pahrump, NV
