Dodge Viper

The Dodge Viper is a two-seat sports car, the most powerful production car made by Dodge. Viper production began at New Mack Assembly in 1992 and moved to its current home at Connor Avenue Assembly in October 1995.

The Viper was conceived as a modern take on the classic American muscle car. While there are some who insist that the iconic AC Cobra was a source of inspiration, the final version of the Viper was far too large and heavy to seriously claim any direct lineage with the compact and lightweight vehicle. Most saw claims to kinship with the Cobra as a marketing exercise, although Carroll Shelby was involved in the initial design of the Viper.

The Viper was initially conceived in late 1987 at Chrysler's Advanced Design Studios. The following February, Chrysler president Bob Lutz suggested to Tom Gale at Chrysler Design that the company should consider producing a modern Cobra, and a clay model was presented to Lutz a few months later. The car appeared as a concept at the North American International Auto Show in 1989, and public reaction was so enthusiastic, that chief engineer Roy Sjeoberg was directed to develop it as a production car.

Sjoberg selected 85 engineers to be "Team Viper", with development beginning in March 1989. The team asked then-Chrysler subsidiary Lamborghini to cast some prototype aluminum blocks based on their V10 truck engine for sports car use in May. The production body was completed in the fall, with a chassis prototype running in December. Though a V8 was first used in the test mule, the V10 which the production car was meant to use was ready in February 1990.

Official approval from Chrysler chairman, Lee Iacocca, came in May 1990. One year later, Carroll Shelby piloted a preproduction car as the Indianapolis 500 pace car. In November 1991, the car was released to reviewers with first shipments beginning in January 1992.

The Dodge Viper underwent a major redesign in 2003, courtesy of DaimlerChrysler's Street and Racing Technology (SRT) group. The new Viper SRT-10 was heavily restyled with sharp, angled bodywork. The engine was enlarged to 8.3 L which, with other upgrades, combined to increased output to 504 hp (375 kW) and 525 ft·lbf (711 N·m) of torque. The initial model was a convertible.

The new Viper SRT-10 Coupe (no longer called the GTS) was introduced in 2005 at the Detroit Auto Show as a 2006 model. It shares many of its body panels with the convertible but takes its side and rear styling cues from the Competition Coupe (see below). The new coupe looks much like the previous Viper GTS and retains the "double-bubble" roof shape of the original, along with the original GTS's taillights, for an added homage to the original Viper coupe. In addition to these style upgrades, the Viper receives 510 hp (380 kW) and 525 ft·lbf (711 N·m) of torque.

The third generation Viper has been sold in Europe since 2004, the first model to be sold as a Dodge, as part of Chrysler's new sales strategy for the European market.
