GM is one of a growing number of automakers that is using the SEMAshow to debut modified or concept versions of existing production models. One of the stars of the GM booth is the Pontiac Solstice SD-290, a modified version of the popular roadster. The SD-290 features a covered passenger cockpit, some sharp body styling, and a turbocharged 2-liter Ecotec power plant good for 290 horsepower (hence the designation). This Solstice also sports a custom front fascia, hood and front fascia, and grille inserts.
Performance upgrades include 3-piston, 13-inch stainless-steel caliper brakes, a custom exhaust from Solo Performance, and a bespoke suspension system from KW Automotive. Inside, the HVAC system and stereo have been sacrificed for weight-saving purposes, as has the windshield. GM says that the rationale for the SD-290 was to pay homage to the "purposeful design of...classic race vehicles". Don't expect to see one of these on the road any time soon.
