It was built at GM's Wilmington Assembly plant in Wilmington, Delaware, alongside the Solstice. The Sky concept was shown at the 2005 North American International Auto Show, with the production version following at the 2006 show. It uses the Kappa automobile platform shared with the Pontiac Solstice. dealers this fall.The Saturn Sky is a roadster that was produced by Saturn, and was initially released in the first quarter of 2006 as a 2007 model.

Pistons feature dish-shaped tops that deflect fuel toward the spark plugs for better combustion. The twin-cam, 16-valve engine also employs a high-strength steel crankshaft and forged connecting rods, aluminum cylinder head with sodium-filled exhaust valves, high-pressure engine-driven fuel pump and a variable pressure fuel rail. The water jacket is deeper for added cooling capacity, and cylinder bore roundness was improved, GM says.
The new powerplant, based on the 2.4L found in the base Pontiac Solstice roadster, makes use of a stronger “Gen II” Ecotec aluminum engine block developed with input from GM’s racing programs.Ĭylinder block bulkheads and bore walls were enlarged to handle the higher power output. GM Powertrain engineers from North America and Europe played rolls in developing the new engine, drawn from the 2.2L DI Ecotec offered in Europe and 2L turbo engines already in production, the auto maker says. The engine features variable valve timing to go along with its twin-scroll turbocharger with an air-to-air intercooling system. (353 Nm) of torque, good enough, GM says, to make it its highest specific output engine ever at 130 hp/L. The new DI 2L turbocharged Ecotec generates 260 hp and 260 lb.-ft. The ’07 Sky Red Line and its ’07 Pontiac Solstice GXP platform mate will mark the first GM cars to offer direct-injection gasoline engines in North America. will pack its most powerful Ecotec yet under the hood of the Saturn Sky Red Line that will be unveiled next week at the New York International Auto Show.
