First Drive: 2009 Dodge Viper ACR
OU'RE looking at Dodge's answer to the Porsche 911 GT3 RS or Lotus Exige, a road car you can drive to the track, hot lap all day, and drive back home, tires, brakes, and ego intact. The Viper ACR is raw. It's wired. And it's probably the best weekend racer yet from Detroit.

The ACR has exactly the same power and torque as the regular Viper-600 horses and 560 pound-feet. The engine drives through a smaller dual plate clutch that reduces rotating inertia by 18 percent and the latest iteration of the Tremec T6060 six-speed that includes triple-cone synchros on first and second, and 10-percent-wider gears to manage the torque. The new GKN ViscoLok diff features its own sump to quicker generate the hydraulic pressure needed to actuate the limited-slip clutches faster, yet more progressively and with greater precision.

Most of the time, effort, and development dollars have been spent on stuff that makes the ACR go faster through the twisty bits-suspension, brakes, wheels and tires, and aerodynamics. Especially the aerodynamics. Just chew on this for a moment: At 150 mph, the regular Viper coupe generates 100 pounds of downforce; at the same speed, the Viper ACR generates 1000 pounds of downforce.

That giant carbon-fiber rear wing is the most obvious reason why. But there's also a new carbon-fiber front splitter that extends way back under the car and incorporates seven steps to diffuse the airflow. The new hood louvers unveiled with the 600-horsepower engine upgrade a year ago play a part, too. "We knew we were going to do a new ACR, so we moved the louvers forward to help change the aero balance of the car," says SRT boss Herb Helbig. Read Article

I guess I'm a hypocrite because I love the new Corvettes but every time I see a Viper, it just reminds me of white trash. I've always hated this car.

i heard in rumors that this viper has the same components as the Honda S2000 CR. dodge thought it would be nice to add "A" to make it seem better.

I like the original Viper GTS coupe from 1996 much better than i like the newer design.

Hmm, it is reviewed extremely well. Take it for what it's worth... a track car and not much more. For that, I like it!

the viper always stays ahead of the gas station attendants dream car. talk about redesign, the new 09 is nothing. that glass on the hood-Beautiful! An option on the 08 stage one has 678hp from dodge. I see almost as many old ladies driving vettes as I do lesuxes. The 09 vette outweighs the viper. Shouldn't have skipped reading in grade school.

Change of downforce went from 100lbs to 1000lbs? is that possible? Can it be a typo?

I just can't believe the ignorance on this site. Most of the comments come from people who have never driven the car or anything similar. This is going to be one of the fastest cars available and it will kill the GTR, M3, etc.....
