In-game description
'' At its heart, Dodge Viper is a thoroughly American sports car driven by an awesome V10 engine. Its adrenaline pumping performance and wholly unique look represent the ultimate prize for those with a true passion for automobiles. It is the conclusive expression of the Dodge "attitude". The Viper GTS Coupe and RT/10 Roadster are powered by the same awesome 488 cu in V10 engine; that power is channeled by a high-performance six-speed gearbox; Viper rides on a classic race-bred sports car chassis and suspension, massive high-performance tires, and heavy-duty brakes. Viper is about driving, about the pure enjoyment of getting from point A to point B. There exists only the driver, the car and the road. Everything else is irrelevant. Viper is designed primarily to become a part of its environment - in the open air, with the air in your face, or on a busy street, filled with people, cars, sights and sounds. ''
