2010 Dodge Viper SRT10 ACR-X: Rare Race-Ready Viper Turns Heads at Auction

For enthusiasts who live and breathe high-performance machines, few names loom as large as the Dodge Viper — and within that family, the 2010 Viper SRT10 ACR-X is one of the most extreme and rare variants ever built. One of just 50 ACR-X cars ever produced recently made its way to a Bring a Trailer auction, offering collectors and racers a chance to own a machine that blurs the line between track weapon and automotive legend.

Legendary Performance With a Track-Focused Edge

The Viper SRT10 ACR-X was conceived as a competition-oriented iteration of Dodge’s already potent ACR (American Club Racer) package. Powered by an 8.4-liter V10 engine, it was originally engineered to make significantly more power, more downforce, and more straight-line and cornering capability than a standard Viper — and in many ways it delivered.

This particular auction car had its powertrain and chassis thoroughly reworked under its current ownership. A Gen 5 six-speed manual transmission and a Wavetrac differential replaced the original hardware, complemented by KW adjustable coilovers with Swift springs for sharper handling on track. Racing-oriented components like RB Performance brake calipers, carbon-ceramic rotors, and Nuke Performance air jacks made it more than capable of competition use.

Modified, Rare, and Purpose-Built

Unlike most street cars, this Viper ACR-X listing notes that the car lacks a VIN and is not legal for road use, meaning it was prepared strictly for closed-course events or dedicated track days. It carries upgraded Sabelt racing seats with Schroth harnesses, an OMP racing steering wheel, and a full fire suppression system — equipment that speaks directly to its track-ready intent.

One of the standout features of this example was its extensive aerodynamic overhaul. Over two years of development with Verus Engineering resulted in a high-downforce aero package with enhanced front splitters, a dramatic rear wing, diffuser, side skirts, and wheel-well vents. These upgrades reportedly doubled downforce over stock figures, making the car significantly more planted through high-speed corners.

A Collector’s Piece With Real Track Pedigree

Though it’s a rare example of one of Dodge’s most hardcore Vipers, the auction car wasn’t your typical showroom-fresh collectible — it was a used, modified race car with roughly 3,000 miles on the clock and significant performance upgrades. In auctions like this, such cars often attract serious bidders who appreciate the blend of rarity and competition hardware.

Bring a Trailer listings of historic Vipers show that highly original ACRs have sold for strong prices when well documented and maintained, illustrating the enduring passion for these fearsome V10-powered machines.
