Background
Dubbed by some a 427 Cobra for the Nineties, the original Viper of 1991 was a production version of a Dodge concept car unveiled in 1989 at the Detroit show. In some ways it showed; the original roadster eschewed such adornments as door handles or a proper roof.
Many half-truths are told about the Viper’s now legendary V10 engine - how it was supposedly a truck motor reassigned. Originally, the Viper was to use a development of the Chrysler LA360 V8 with, in effect, two extra cylinders. And yes, that engine was also destined for use in Dodge’s Ram line of trucks. However, a new V10 was also being developed by Lamborghini (then also owned by Chrysler). Lamborghini’s design refinements led to the two projects separating and the Viper motor eventually being cast in alloy. (I suppose they could still be cousins).
A big development in Viper evolution came in 1995 with the introduction of the second generation, the SRII. Many aspects of the mechanicals were refined or upgraded and the V10 now put out 415hp and 488 ft lb of torque. Some suspension parts were now aluminium rather than (heavier) steel. The roadster now sported a proper targa roof and sliding glass side windows.
Most notably, Dodge introduced a coupe version; the Viper GTS which would also go on to race in a considerable number or endurance events and race series.
