Fast Cars          2009 Dodge Viper ACR



 

2009 Dodge Viper ACR - You'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.
 

2009 Dodge Viper ACR - 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.
