2010 Dodge Viper ACR-X

With the Viper's uncertain future -- not to mention sales figures that are well below what we saw in its prime -- one might not expect Dodge to roll out anything new wearing the snake badge. But it turns out that where there's a will (or parts), there's a way (or bored engineers). Enter the 2010 Dodge Viper ACR-X, a factory turn-key race car that will compete in the upcoming Dodge Viper Cup spec-racing series.

The ACR-X is a modified version of the Viper ACR, but one big difference is that the ACR-X isn't street legal, so don't plan on ordering a custom license plate for it. No, X doesn't mean all-wheel-drive; in fact, it doesn't have a denotation, except perhaps Xtreme. The ACR-X comes complete with a gutted interior, a full roll cage, a fire suppression system, a race seat, a six-point harness, and a MOMO steering wheel, all topped off with Michelin R compound racing slicks. It uses the ACR's same mammoth 8.4-liter V-10 engine, but here it produces a back-bruising 640 hp at 6100 rpm (40 hp more than the street-legal ACR) and 605 lb-ft of torque at 5100 rpm (45 lb-ft more than the ACR). The added thrust comes courtesy of engine programming and a free-flow exhaust system that is deafening inside the cockpit but manages to sound oh, so sweet. The six-speed manual transmission comes with a short-throw shifter that provides a sturdy feel.

Where the X really separates itself from the ACR is in the handling department. The springs are 50 percent stiffer and work well with the custom two-way adjustable dampers. The rear sway bar is the same size but is adjustable. As with most race cars, downforce plays a major roll in high-speed stability. In the ACR-X's case, the deck-lid spoiler has an adjustable pitch angle at the rear of the car, and two additional dive planes were added to the front bumper. The result is up to 100 pounds of added downforce at 150 mph.

Excitement of a great car is downplayed by this guy who talks like his grandma just died.

Call me crazy, but what if Dodge downsized the current Viper, made it more comfortable, and used a blown Hemi and 6spd tranny. I recall the COBRA came in various iterations.. not all of them were 427 SuperSnakes!

You tell us all about the incredible exaust sound and then you cover it up with a crappy music(?) soundtrack.
