Addition of a high-performance Red Line model is the latest highlight for Saturn's two-seat convertible. Sky shares its basic design with the Pontiac Solstice, but differs in styling, features, and price. Like Solstice, Sky has rear-wheel drive, 4-cyl engines, and a manual-folding soft top with heated glass rear window. The top folds into the trunk. The base Sky has 177 hp. Red Line's 4-cyl is turbocharged to 260 hp and is shared with the Solstice GXP. Both offer 5-speed manual transmission and an optional 5-speed automatic. Red Line has specific suspension tuning. ABS is standard, but only Red Line offers traction/antiskid control, which is standard. No side airbags are available. Both models come with air conditioning, cruise control, and power windows/locks. Leather upholstery is optional. Sky's performance and accommodations mirror those of comparably equipped Solstices.
