Chrysler Viper GTS-R

The Chrysler Viper GTS-R (also known as the Dodge Viper GTS-R when raced in North America) was a successful racing variant of the Dodge Viper developed in conjunction with Chrysler of North America, Oreca of France, and Reynard Motorsport of the United Kingdom. Officially unveiled at the 1995 Pebble Beach Concours, it has won numerous championships and famous events in its history. Some chassis are still in use today.

In the early 1990s, first generation Dodge Viper RT/10s had been modified by racing teams for use in GT racing in North America and Europe without much success. Although its V10 engine was powerful, the car was not adapted to racing and teams lacked the funding to build a car that could compete with factory efforts. One key issue was the fact that the Viper was a roadster, therefore lacking the rigidity that a coupe bodystyle would have. However, following the sales success of the first generation Viper, Dodge began redesigning the car in 1995, upgrading the roadster while at the same time adding a new coupe, known as the Viper GTS.

Although the first generation Vipers had sold well, Dodge wished to showcase the potential capabilities of the new car, mostly in the realm of handling. At the same time, Dodge also hoped to increase sales in Europe where importation of the Viper had struggled. Dodge's parent, Chrysler, therefore approved the development of a racing program centering on the Viper GTS which was still in development at the time. This co-development would allow for elements of the racing car to be adapted to the road car, and vice versa, for each car's mutual improvement.

Chrysler believed that in order to adapt their car not only for North American but also European circuits, they would require outside assistance. An agreement was made with the French racing and engineering firm Oreca, who had many years of experience in sports car racing as well as assistance in the Mazda 787B's win in the 1991 24 Hours of Le Mans. Oreca would construct and maintain the racing cars in their shops, as well as run Chrysler's official factory teams in Europe. For North America, Chrysler would recruit the Canaska/Southwind Team as their factory effort.
