The 2008 Pontiac Solstice lineup gains a pair of new sport-themed models as well as additional standard equipment. This rear-wheel drive convertible seats two and has a manual-folding soft top with heated glass rear window. It shares its basic design with the Saturn Sky. Solstice comes in base and high-performance GXP trims. Base models have a 173-hp 2.4-liter 4-cylinder engine. GXPs have a turbocharged 260-hp 2.0-liter 4-cylinder. Both are available with a 5-speed manual or 5-speed automatic transmission. Available safety features include ABS, traction control, and an antiskid system. Side airbags are not offered. Newly standard on all Solstices are OnStar assistance and a "premium acoustic headliner" designed to reduce engine and road noise in the cabin. Also new for 2008 are the Solstice SCCA SSB and SCCA T2 Champion Edition models. The former has the same powertrain as the base Solstice, while the latter is based on the GXP. Both new models have standard 18-inch performance tires, sport suspension, and leather upholstery.
