Interesting pre-production version of Viper. It looks similar to VM-02 concept, but has already another (as in production) head and fog lights, wheels, front bumper and mirrors. Only one photo of this known. But it is not real pace car of 1991 Indy 500.
The first Dodge Shelby Viper sketches of 1988.
