Background
In the late eighties, Chrysler wanted to resurrect some interest in muscle cars and produced a Dodge Viper concept at the 1989 Detroit motor show, dubbing it a “Cobra for the nineties”. However, Chrysler Chairman Lee Iacocca was backing a joint sportscar project with Maserati and withheld funding approval for the Viper until May 1990. By this time though an alloy, 8-litre V10 had been co-developed for the Viper by Lamborghini - part of the Chrysler group at the time.
A last-minute call up as the pace car for the 1991 Indianapolis 500 - driven by no less a legend than Carroll Shelby - saw a pre-production car get an unexpected public showing, with production units in the hands of journalists by the end of the year and retail sales from January 1992.
The first generation RT/10 - also known as SRI - was a roadster with side-exit exhausts and a soft top hood with zip-up vinyl side windows. The huge 8-litre (488 cu in) engine was rated at 400 hp and gave a 0-60 mph time of 4.2s accelerating to a top speed of 165 mph.
The SRII was introduced in 1996, doing away with the pedestrian un-friendly exhausts, installing proper side windows and replacing the soft top with a removable targa hard top. They also found another 15 hp from the V10.
Later the same year a full coupe variant with a “double-bubble” roof was launched - known as the GTS - which dialled up power to 450 hp. This power upgrade was also made available to the targa and subsequent in-life upgrades continued on both models.
The third generation came along in 2003 and the Viper continued through two further design evolutions until its eventual demise in 2017.
