The Dodge Viper has been seen several times in testing, easily recognizable even when wrapped up in camouflage. Allpar has been told that the Viper will start production in the fall of 2012, as a 2013 model. This falls in line with previously disclosed dates of mid-to-late 2012.
We were told that the Viper would be powered by an 8.7 liter engine. At around 531 cubic inches, it would be the largest engine ever used in a Chrysler production car, by a good margin. Ralph Gilles is on record as saying Viper would retain a V10. The engine might actually be destined for another vehicle, but there are few cars in the world that would use an engine of that size.
Spy shots have already extended to the interior, though it’s likely that the interior photographed was made from parts that were handy, not parts that will be used in the final version. The 1990s climate control and 1990s-2000s stereo both indicate use of an “extra parts bin” versus “prototype components.”
