From the Revell website:
A 400 horsepower aluminum-alloy V-10 engine shoots from 0 to 60 mph (0 to 97 km/h) in 4.6 seconds, with a 164 mph (264 km) top speed - that is power. When Chrysler® built the first RT/10 Vipers they left out all the superfluous items most cars carry, like windows and roofs, and focused on what was important, the engine. This scale model kit features the original Vipers in red, white, and transparent resin with chrome detailing. The model brings detail to life with brakes, suspension, side exhaust and factory detailing decals.
