Dodge Viper GTS
The Dodge Viper is one of the first V10-powered cars in the world.
A coupe model called the GTS was introduced in 1996. Dubbed "double bubble", the roof featured slightly raised sections above each seat to accommodate usage of helmets, a throwback to its intended purpose. Vipers can be seen participating often in drag racing and road racing. The GTS, like its predecessor, was chosen as the pace car for the 1996 Indianapolis 500.
Despite its similar outward appearance, the car was distinct enough to be considered a new generation model. Extensive modifications included a reworked engine with higher power and less weight, an almost completely redesigned chassis that was made 60 lb (27 kg) lighter and 25% stiffer in torsional rigidity through meticulous computer analysis, a thoroughly redesigned suspension, and reduced braking distances.
Along with the updated performance came the inclusion of some of the "luxuries" the car did without before. Dual front airbags were added to the vehicle's safety equipment list in 1996 on the GTS was mandated by the government.
