The Chevrolet SSR builds on Chevrolet’s semi-forgotten tradition of curvy trucks, so it is not just an imitation of the PT Cruiser or Plymouth Prowler. The Chevy SSR combines the open air of a sports roadster with a pickup bed. A retractable hardtop - which remains in the production version - makes it a practical street machine. The two-piece power retractable hardtop stows vertically between the seat and the rear storage bed. Like the Trailblazer, which it is based on, the SSR features a hydroformed steel frame with eight crossmembers for stiffness and handling. The engine crossmember was modified to fit the SSR’s V-8.
