The Saturn Sky is the only sports car from the Saturn marque of American automaker General Motors. It was released in the first quarter of 2006 as a 2007 model. It uses the Kappa automobile platform shared with the Pontiac Solstice and Opel GT. The Sky concept was shown at the 2005 North American International Auto Show, with the production version following at the 2006 show. It was built at GM's Wilmington, Delaware plant, alongside the Solstice and the Opel GT. The Sky features 18 inch (457 mm) wheels and a 2.4 L Ecotec LE5 straight-4 engine that produces 177 hp (132 kW), a new straight-4 2.0 L direct injected engine that makes 260 hp (194 kW) as well as a turbocharged (dealer upgrade kit) version that makes 290 hp (216 kW). Both five-speed manual and automatic transmissions are available.
The styling for the Sky, penned by Franz von Holzhausen, is based on the Vauxhall VX Lightning Concept's design. It is available in some European markets as the Opel GT. A rebadged version named the Daewoo G2X was unveiled as a concept vehicle for the South Korean market in 2006. The production version was released in September 2007. The Solstice, Sky, and GT are built in Delaware, as was the G2X until 2008. The aggressive styling garnered praise as a welcome departure from traditional Saturn design.
A Red Line model of the Sky was introduced on April 11, 2006 at the New York Auto Show. It uses the same 260 hp (194 kW) turbocharged Ecotec engine as the Solstice GXP and Opel GT, as well as the same standard 5-speed Aisin manual transmission. An automatic transmission is optional.
