1997 Space Frame exiting one of two (2) ovens GM used to cure the Ciba-Geigy bonding adhesive. The red areas are the front strut towers which are riveted to the to the lower frame rails and bonded and riveted to the outer rails. The blue areas protruding below the strut towers are the front bumper mounting brackets and the center blue area is the lower cross member which supports the cradle and front motor mount.
Not sure what the blue paint markings denote in the following photos, as they do not appear on 1997 production vehicles. That leads us to believe that these photos are likely pre-production build-bucks for structural and fitment testing. Note the collections Build-buck.
Note the large square access hole inside the rear wheel-well. On the 1997 production EV1 this is a much smaller, rounded, opening for the rear cooling fan duct. This feature leads speculation that these may be 1994 timeline photographs or pre-production testing of some sort.
