Spy shooters have caught a bit of pure eye candy–a Dodge Viper SRT10 ACR.

These shots are nice and clear, showing the silver-and-black color combo. We see the familiar grille and door panels, and there’s a huge wing on the back to help keep this beast from going airborne.

Power comes from the aluminum, 8.4-liter V10 that pumps out 600 hp and 560 lb-ft of torque.

ACR is short for American Club Racer. It’s a track car that happens to be street legal. The SRT guys cut the weight, race-tuned the suspension and improved the aero. Vipers are hand-built in Detroit.

The shots appear to be of a 2009 VOI X commemorative edition car to be raffled by the Viper Club of America next month. Dodge is outfitting 100 Vipers with this package, and the raffle car will by the only ACR version, a club official said.

AutoWeek was treated to a short stint in the ACR last summer. Out take: it’s one of the most menacing cars you can buy. One staffer memorably called it “fun, intimidating, flamboyant and a giant middle finger to the environment all wrapped up in one car.”

Oh, and this thing blitzed the Nurburgring faster than the Corvette ZR1.

The fate of Viper is uncertain. But let’s hope there’s a deep-pocketed investor with a passion to keep this going.

Editor’s Note: This story originally called the spied car a 2010 model. After further investigation, it appears to be the commemorative edition. Most of those will be coupes, but we appear to have caught the only ACR version.
