In the early 2000s, every automaker was chasing the family-friendly crossover. Dodge, meanwhile, took the 8.3-liter V10 out of its Viper sports car, dropped it into a Ram 1500 pickup, and put it on dealer lots for under $46,000. The result was the Dodge Ram SRT-10: a 500-horsepower truck with a Guinness World Record to its name and a ride that reviewers found punishing.
It is one of the stranger things a major American automaker has ever built on purpose, and it's worth looking at how it came together, what it was like to live with, and why it's worth more now than most trucks of its era.
A Viper Engine, a Truck-Sized Hole
The idea wasn't entirely new. According to Wikipedia's account of the model, Dodge had shown a V10-powered Ram VTS concept at the 1996 Chicago Auto Show, and an SRT-10 concept appeared at the Detroit auto show in January 2002. Production followed quickly: the first SRT-10 was built on November 10, 2003, as a 2004 model.
The truck came out of DaimlerChrysler's Performance Vehicle Operations group, the team behind the Viper and the Plymouth Prowler. The company has never published a boardroom story about how the project was signed off, but the logic described in Hagerty's look at the third-generation Viper and the SRT-10 is hard to argue with: there was room in the engine bay, so why not? Dodge already had the engine, built at its Conner Avenue plant in Detroit, and the Ram 1500 was already being assembled in Saltillo, Mexico.
The engine itself was the 8.3-liter (505 cubic inch) V10 from the third-generation Dodge Viper, rated at 500 horsepower and 525 lb-ft of torque. Dodge's own press materials describe a 0-60 time in the mid-five-second range, while other reference sources put the regular-cab truck closer to 4.9 seconds. Either way, it was fast enough to embarrass plenty of sports cars.
The regular cab came only with a Tremec T-56 six-speed manual. A Quad Cab joined the lineup for 2005, but it was automatic-only, using a four-speed, and it was a little slower and more practical, with a higher tow rating.
The Guinness Record
Dodge wanted proof that the truck wasn't just a styling exercise. In early February 2004, NASCAR Craftsman Truck Series driver Brendan Gaughan took a stock SRT-10 around the DaimlerChrysler Proving Grounds in Chelsea, Michigan, and averaged 154.587 mph across two runs in opposite directions over a flying kilometer. According to Dodge's press release, the attempt was certified by Guinness World Records and the Sports Car Club of America, and the truck came straight off the assembly line without modification.
That beat the 147.54 mph mark set by the Ford SVT F-150 Lightning in 2003, a truck Motorious has called the most evil truck ever mass produced. (The SRT-10 later lost the title to Holden's HSV Maloo in 2006.) For more on the record run, see our earlier piece on the record-breaking sports truck.
Living With It
The SRT-10 was not subtle, and it wasn't meant to be comfortable. A 2004 road test published by Forbes listed the price at $45,795 and put the truck at 5,194 pounds, with EPA ratings of 10 mpg city and 15 mpg highway. The reviewer averaged roughly 12 mpg. The suspension was stiff enough that rough pavement bounced the truck around, and the lack of electronic stability control made wet roads a concern. The verdict was essentially that it was brilliant in a straight line and tiring everywhere else.
Dodge leaned into the strangeness with special editions, including the 2005 Yellow Fever and the black 2006 Night Runner. Sources disagree on exact production totals, ranging from about 9,500 to just over 10,000 trucks across the 2004 through 2006 model years, but all agree on the order of magnitude: this was a niche product from the day it launched.
What Became of It
Production ended after the 2006 model year, and the SRT-10 had no direct successor. The Viper that supplied its engine eventually went away too, which makes the truck an even odder footnote today.
Collectors have noticed. Hagerty's valuation data showed excellent-condition regular cabs climbing 46 percent to $54,200 between 2019 and 2021, with Quad Cabs trailing at about $31,700. A 1,500-mile truck sold for $79,800 on Bring a Trailer in January 2021, and a 245-mile example brought $68,200 at Mecum Indy that year. Manual regular cabs are the ones people chase, and we've followed several, including this 50K-mile 2004 example.
It's easy to see why the SRT-10 never became a mainstream success. It was thirsty, harsh, and expensive. But as an example of what happens when engineers are handed a great engine and a gap in the engine bay, it's hard to beat.
