Chrysler has revealed the 2008 Dodge Viper SRT10 — a more powerful version of its popular two-seat sports cars. It will arrive in Dodge showrooms in North America this summer. The SRT model gains an additional 90 horsepower from the new 8.4-liter powerplant, for a total of 600 hp and 560 lb.-ft. of torque.

Zero to 60 mph takes under four seconds, and 0-100-0 mph is completed in just over 12 seconds. The Viper SRT10's 8.4-liter engine breathes through new cylinder heads equipped with CNC-machhined combustion chambers, larger valves and Variable Valve Timing (VVT). VVT electronically adjusts when the exhaust valves are open and closed according to engine speed and load.

The Viper SRT10's V10 channels its power through a new, smaller-diameter, twin-disc clutch. The transmission is the latest evolution of the Tremec T56 six-speed manual, known as the TR6060. It features 10 percent wider gears for higher torque capacity and a new synchronizer package. Stopping power is another key attribute of the Dodge Viper SRT10 formula, with 14-inch brake rotors gripped by Brembo dual opposing calipers, good for 60-to-0 mph in less than 100 feet.
