The Sky featured 18-inch (457 mm) wheels and a 2.4 L Ecotec LE5 inline-four engine with direct injection and variable valve timing that produced 177 hp (132 kW), a new 2.0-litre turbocharged direct injected inline-four engine also featuring VVT that made 260 hp (194 kW) and 260 lb⋅ft (353 N⋅m).

[1] The Wilmington Assembly plant closed in July 2009, ending production as both the Pontiac and Saturn nameplates were retired.

It uses the same 260 hp (194 kW) turbocharged Ecotec engine as the Pontiac Solstice, as well as the same standard 5-speed Aisin manual transmission.

Other exterior enhancements included dual tip exhausts, 18-inch wheels, and a specific front fascia modeled for the Red Line.

The Sky featured one fewer hand-hold than the Solstice, instead placing the vehicle's electrical socket nearby the lost appendage.

The Sky had an alternate rear fascia to the Solstice, showing a lower singular reverse light and smoother texture.

The largest differentiator, however, is Carbon Flash Edition's silver inserts in the interior seating and steering wheel that provide a black-on-silver appearance.

All Hydro Blue Edition Saturn Sky units were sold with the removable silver racing stripe.

GM had planned to make 500 Hydro Blue units to match the 500 Ruby Red Special Edition Sky build count.

However, Hydro Blue units were being built as GM was declaring bankruptcy, resulting in the immediate termination of the Kappa platform.

In April and May 2009 the Wilmington, Delaware, plant built thirty 2010 model year VIN-coded cars on the Kappa platform.

[12] The South Korean version was only offered with the turbocharged 264 PS (194 kW) engine from the Sky RedLine, combined with the five-speed automatic transmission.
