Viper TA (United States of America, 2014)

In 2012 the American auto magazine Motor Trend pitted a brand new SRT Viper GTS against the sixth-generation Chevrolet Corvette ZR1 around Laguna Seca. The two cars are evenly matched technically with just 2hp and 4lb-ft of torque between them, but the Corvette was two seconds faster per lap. The loss was a shock to many Chrysler fans, including SRT head Ralph Gilles. So in 2013 SRT launched the 2014 SRT Viper TA (Time Attack).

“The new 2014 SRT Viper TA is being engineering for the dedicated track enthusiast, who still wants to drive to the track and take their hobby to the next level” said Gilles.

The TA will be limited to 33 units with no available options. It gets an upgraded suspension built specifically for track driving, lighter wheels, and the two-mode Bilstein suspension. The suspension gets stiffer springs and dampers and stabilizer bars derived from the GTS-R racecar. The car's aluminum X-brace is replaced by a carbon fiber version. All of the modifications bring the curb weight to 3,368lbs, which is 6lbs less than a standard Viper, 26lbs less than a Viper GTS with the SRT package and 5lbs less than a Corvette ZR1.

The TA also gets new black anodized Brembo brakes with increased thermal capacity and better heat dissipation.

"Our engineers revised the suspension settings to refocus the Viper specifically for track duty, using a blend of components from the GTS and the SRT models, add in the extensively developed aero package and the new Time Attack package is born," said Gilles.

The cars will only be available in Crusher Orange with TA logos on the fenders and a black hood emblem. It also gets a carbon fiber front splitter and carbon fiber rear spoiler.

The 8.4-liter V10 is left untouched with 640hp and 600lb-ft of torque.

The interior gets Sabelt racing seats with racing harnesses. It also has Crusher Orange stitching on the seats, instrument panel, center console, handbrake and steering wheel.
