2010 Viper SRT10 ACR-X Revealed [Video]

Packs 640 hp

Dodge has unveiled their new turn-key racer, the Viper SRT10 ACR-X.

Based on the Viper ACR, the ACR-X is a track-only race car designed to compete in the Viper Racing League, the Sports Car Club of America, and the National Auto Sport Association.

Power comes from an 8.4-liter V10 engine that produces 640 horsepower (40 hp more than the standard model). Other performance tweaks include a specially-tuned sports suspension, a 160 pound weight reduction (compared to the standard production Viper), improved aerodynamics (for increased downforce), and a complete safety package (with a roll cage, fuel cell and race seat).

During testing at Laguna Seca, the Viper ACR-X averaged a time of 1:31.00. As you may recall, the street-legal Viper ACR set the production car lap record at Laguna Seca, last November, with a time of 1:33.944.

According to Dodge's President and CEO, Ralph Gilles, "The Dodge Viper ACR-X takes the performance attributes of Viper to an even higher level for a wide range of drivers starting with the grassroots racer all the way up to the professional. This project is a result of many years of performance engineering expertise from our SRT team, combined with the passion and dedication of Viper Nation, to keep the Viper racing tradition going strong on tracks around the country and the world."

Set to go into production this spring, the Viper ACR-X will be priced from approximately $110,000 USD.

  • Turn-key, spec-series racer aimed at continuing Dodge Viper’s storied racing history
  • Dodge and Street and Racing Technology (SRT) team combine best performance attributes of Viper ACR with Viper Competition Coupe
  • Latest special-edition Viper ACR offers improved on-track performance and safety
  • Dodge Viper Cup spec series will debut in July 2010

Dodge today pulled the cover off the newest special-edition model of the 2010 Viper SRT10 lineup. The Dodge Viper SRT10 ACR-X is a turn-key, non-street legal race car that is slated to make its on-track debut in the summer of 2010.

“The Dodge Viper ACR-X takes the performance attributes of Viper to an even higher level for a wide range of drivers starting with the grassroots racer all the way up to the professional,” said Ralph Gilles, President and CEO, Dodge Brand. “This project is a result of many years of performance engineering expertise from our SRT team, combined with the passion and dedication of Viper Nation, to keep the Viper racing tradition going strong on tracks around the country and the world.”

Combining the best performance attributes of the record-setting, street-legal Dodge Viper ACR (American Club Racer) and the safety equipment of championship-winning Viper Competition Coupe, the Viper ACR-X is powered by the SRT-developed 8.4-liter V10, equipped with factory headers and a low-restriction exhaust system, that produces 640 horsepower (40 more than production model).

The suspension also is tuned and upgraded specifically for on-track usage, while the weight is lightened by a full 160 pounds (versus the standard production Viper) to take on even the most challenging road course. Additional aerodynamic upgrades improve downforce, while enhancing stability and significantly improving grip in high-speed cornering.

Similar to the Dodge Viper Competition Coupe, the Viper ACR-X contains factory-installed safety equipment such as a factory-designed roll cage, fuel cell and race seat. Additional racing components are added to meet the significant durability and reliability requirements for on-track competition.

In what will be the final year of production for the current generation Viper, the ACR-X is the third limited, special-edition model to be introduced by Dodge. ““We’re going to make 2010 the most exciting year for Viper yet with specially developed cars for the street and the track,” added Gilles. “The ACR-X is targeted at road-racing enthusiasts who want to successfully compete in our ultimate American sports car.”

Last month, the SRT team used a testing session at Laguna Seca raceway to shake down the Viper ACR-X for the first time. Behind the wheel was professional driver Kuno Wittmer from the SCCA Pro Racing SPEED World Challenge Touring Car Championship series, who was able to run consistent 1:31.00 lap times around the 2.238-mile, 11-turn course. Wittmer’s lap times were more than 3 seconds faster than the street-legal Dodge Viper SRT10 ACR that holds the production car track record at Laguna Seca raceway.

"The Dodge Viper ACR-X is incredible,” said Wittmer. “After a short warm up, I was running lap times as quick as exotic GT race cars. I was blown away by the power and acceleration, and even more surprised at how the ACR-X navigated the challenging Laguna Seca corners and how friendly it was to drive at the limit.

“All aspects of the car work together perfectly to plant all that horsepower and torque without issue,” Wittmer added. “This will be a great package for someone coming out of grassroots racing with a desire to step-up to GT level competition. Dodge nailed it with this one!"

The Viper SRT10 ACR-X is designed to compete in the Viper Racing League, Sports Car Club of America and National Auto Sport Association events.

Manufacturer’s Suggested Retail Price (MSRP) for the Dodge Viper SRT10 ACR-X will be approximately $110,000. Production is slated to begin in Spring 2010.

Viper Racing Heritage:

The Dodge Viper has enjoyed a successful racing heritage that began in 1996 with the original Viper racing entry, the GTS-R, which earned five international GT championships and the 1997-1999 FIA GT championships. It also posted an amazing overall win at the Rolex 24 Hours of Daytona in 1999 – the first for a production-based American car.

The Dodge Viper Competition Coupe, introduced in 2003, delivered the next chapter with its coupe-shaped carbon/Kevlar body and a track-ready chassis, based on the Dodge Viper SRT10. The Viper Competition Coupe has continued the on-track prowess by capturing the 2004 SCCA Speed World Challenge GT title, championships in Formula D Drifting series in 2004 and 2006 and the British GT Championship in 2007 and 2008.

i have read the entire article. and i recall the upgrades, but i think very little was done to the transmission. yes, nice engine (i think), nice aerodynamics, nice suspension...nice "the entire package" but that tranny seems so antique. they say the 133 can do 184, joe lemon says "no it does 200"...say what my man? you mean to say that the manufacturer lies? how fast can this 133-x can go? dont get me wrong, great car but....but...everything about it is so uber, and the performane, not so uber.. at least not on my list.

The main reason they won't change the transmission on regular models is for fuel economy. However this is a track only model where less emphasis is on fuel economy(except in endurance races) so my guess is making the transmission too tight might make the car have questionable gas mileage(on a track). This is just a theory though, anybody can prove me wrong. I agree that the performance increase over the regular ACR isn't too much but still as far as track only specials go this car is highly competitive, especially against cars more expensive. Im not saying it will flat out beat them but it'll get you within their range of times at least.

"In 2010 the "standard" Dodge Viper SRT10 ACR receives a new short-throw shifter, redesigned rear wing for improved aerodynamics and a new fifth gear ratio which increases top speed by 4 mph to 184 mph." http://www.worldcarfans.com/109120323364/dodge-viper-acr-133-edition-announced-for-2010 read and know your facts, as you said....einsteins. and this X edition, has what in adition to the "standard" 133?

It has a new 5th gear ratio and the new 5th gear affects top speed because of how wide the 6th gear is making it unusable for anything but fuel economy(revving at 1500rpm on the highway in 6th). The Viper has always had a 6 gear.

ok,. same engine, 40hp plus, and i bet it has the same 5 speed gearbox, and this increase in power and decrase in weight gives it another 4mph, over the 184 mph top speed? for chrissakes... nice car but, for chirs'sakes

What are you talking about? The viper has never had a 5 speed gearbox. And wayyy back in 96-02 the vipers with 415hp had a top speed of 187mph... the current gen is over 200mph

Norther, no disrespect but before you slam any car you should know the basic facts or specs in this case. Ive made the foot-in-mouth mistake before, it makes one look foolish even when he isn't.

Mercedes, BMW, Lamborghini, Porsche are only a few examples with normally aspirated engines with at least 100hp/liter.

My question was what does hp/liter tell you about a car? Not what car manufacturers stress their engines.

Right on Joe_Limon!! This is yet another great american car, now we have 2 great cars that trump the world including the ZR1. Who cares how much hp per litre a car can produce... Those Lambo's Ferrari's produce a lot of hp per litre but also fall apart shortly after. Look at the F430, after 20,000 miles, its 0-60 time drops off by 0.7 seconds? Thats significant! You will never see that happen with a Viper or ZR1 or any other Vette for that matter, actually you will get even quicker times after 20,000 miles. Just take a look at the most recent 1/4 mile run by a bone stock 2009 ZR1, 10.85 seconds! What current bone stock foreign production car can match that? They all are in the 11 second range

lol 640hp out of a 8.4 liter? It probably also comes with a lifespan of just 2 track laps, but you don’t have to worry about that because you’ll run out of fuel in just 1. This car can suck a monkeys nut!

All the foreign competition seem to make at least a 100hp/liter so why does not the Viper make an easy 800 hp?

How many of those engines either have forced induction or are highly stressed? The GEN IV Viper makes over 600hp in a relatively mild state of tune. Add exhaust and SRT ECU and you're around 650hp. There are supercharged and turbocharged Viper running aound with 700 to over 1000 horsepower.

You still haven't answered Joe. What good is horsepower if you're not able to utilize it? A 300hp BMW 335 outperforms at 425hp Dodge Charger SRT 8. This 640hp Viper is holding it's ground with those foreign competitors. So... what are you trying to get at? I swear, this site is filled with a bunch of kids who have never driven anything more than a crappy 4-banger, but on here they act like they have a clue.
