From the Press Release (it's late, I'm tired):
Configured in-house by the Chrysler Group’s SRT (Street and Racing Technology) team in collaboration with professional road racers, the exclusive, street-legal and single-spec 2014 SRT Viper TA (Time Attack) package is specifically built for the performance enthusiast driver who likes to exercise their machines at the more than 150 road-race courses around North America.
Under the hood of the 2014 SRT Viper TA is the handcrafted, all-aluminum 8.4-liter, mid-front V-10 overhead-valve engine. Performance ratings are 640 horsepower and 600 lb.-ft. of torque – the most torque of any naturally aspirated sports-car engine in the world.
“The new 2014 SRT Viper TA is being engineered for the dedicated track enthusiast, who still wants to drive to the track and take their hobby to the next level” said Ralph Gilles, President and CEO – SRT Brand and Motorsports, Chrysler Group LLC. “We’re re-launching some of the fastest production-built cars that people can buy straight from the factory. 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. We’re not only saluting the existing capabilities of our current models, we’re also targeting another niche in our customer base with a tremendously capable track machine.”
Inside, the performance driver-oriented cabin of the 2014 SRT Viper TA uses the same standard premium ballistic fabric racing seats from Sabelt, featuring a lightweight fiberglass shell created by a state-of-the-art resin transfer molding technology for mass reduction and long-term durability. Both driver and passenger seats can also accommodate a 3- or 6-point harness for racing belts.
The standard black interior combination includes unique orange accent stitching on the cloth seats, instrument panel (through the cowl), center stack, console, pull brake, shifter boot, shifter head, steering wheel and upper doors.
