Both trims of the 2008 Saturn Sky handle well, and the more powerful Saturn Sky Red Line is very capable off the line, thanks to its turbocharged engine.
The engines on the 2008 Saturn Sky lineup are two very different beasts; Edmunds says that the "base-model 2008 Saturn Sky comes with a 2.4-liter inline-4 engine that makes 177 hp and 166 pound-feet of torque," while the Red Line version of the Sky Saturn "has a turbocharged 2.0-liter four-cylinder with direct injection capable of a very strong 260 hp and 260 lb-ft of torque." Impressions of the engines vary considerably in reviews read by TheCarConnection.com, as reviewers understandably favor the stronger 2.0-liter version over the 2.4-liter engine. ConsumerGuide remarks that "the base engine is slow to rev and has little power reserve for quick highway passing," and Cars.com laments that "you have to get the engine revving pretty high to get appreciable power out of it." Fortunately, the Saturn Sky Red Line steps in to provide a more enthusiastic driving experience. Whereas "the regular Sky went from zero to 60 mph in 7.5 seconds," Edmunds claims "the Red Line challenges the Porsche Cayman at 5.8 seconds."
Both versions of the Sky Saturn are available with one of two transmission options, but neither scores particularly well with reviewers. Cars.com says that "the short gearshift" on the "five-speed manual" is reasonable, but notes that "a sixth gear is nice to have," and in particular, "the Sky really needs it." The other available option is "a 5-speed automatic transmission" that "costs $925 extra," according to Road & Track. However, Cars.com warns against the automatic paired with the base engine, saying "modestly powered engines and automatic transmissions are the worst combination." The situation improves on the 2008 Saturn Sky Red Line, where ConsumerGuide claims "the automatic transmission has no real penalty vs. the manual."
One of the benefits of an engine with a small output, such as the 2.0-liter or 2.4-liter offerings on the Saturn Sky lineup, is that it usually affords good fuel economy. That is true on the 2008 Saturn Sky; the EPA estimates the Red Line will return 19 mpg city and 26 mpg highway with the automatic transmission and 19 mpg city, 28 mpg highway with the manual. The less powerful engine on the base Saturn Sky actually gets worse mileage numbers, rating 19 mpg city and 24 mpg highway with the automatic, according to the EPA, and 19/25 mpg with the manual. In real-life testing, ConsumerGuide reports their base Saturn Sky "with manual transmission averaged 20.8 mpg in mixed driving," while the "test manual-transmission Red Line averaged 20.1 mpg in mostly city driving."
Another area where the 2008 Saturn Sky shines is in terms of handling and ride quality. ConsumerGuide remarks that "the ride is supple enough for sports cars" on the base model, but "the sport suspension used on Red Line" is a bit tauter, "so impact harshness is more noticeable." However, the tauter suspension definitely improves handling, and Edmunds reviewers say "most drivers will find the car's substantial lateral grip and quick steering enjoyable enough to make the Sky a fun and engaging twisty road companion." Cars.com also raves that, "in terms of overall performance, the Sky's ride and handling are where it shines the brightest." When it comes time to stop, Cars.com attests that the brakes are "highly effective four-wheel discs with standard ABS."
