2009 Saturn Sky Red Line

Saturn introduced a high-performance version of its Sky roadster for the 2007 model year called Red Line. The respectable Sky gets a boost in performance from an Ecotec turbocharged 2.0-liter engine -- GM's first direct injection offering in North America.

It produces 260 horsepower at 5300 rpm and 260 lb.-ft. of torque at 2500 rpm, giving it the best horsepower-to-displacement ratio of any GM engine (130 hp per liter). The powerplant is also the most powerful motor in the Ecotec family.

Gasoline direct injection technology helps the engine produce more power while maintaining the lower fuel consumption of a small displacement port-injected engine. With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower.

In addition to more power, the car's chassis has been tuned for better handling and its braking system has been upgraded for quicker stopping. Other technical highlights include a torque-sensing limited-slip differential and StabiliTrak electronic stability control.

Like all Saturn Skys, the Red Line model boasts a near 50:50 weight distribution, independent front and rear suspension, an extremely stiff body, and coil-over Bilstein monotube shocks.

The Red Line also features several unique interior and exterior differences compared to the Sky roadster, including dual exhaust with chrome polished outlets, 18-inch polished aluminum wheels, and a redesigned front apron with large vents and black headlamp bezels.

The interior features a leather-wrapped steering wheel with audio controls, unique seatback and floormat embroidery, metallic sill plates, stainless steel pedal covers, Red Line-specific gauges and a digital boost gauge included in the Driver Information Center.

The Sky Red Line has a handful safety features, including dual-stage front air bags, four-wheel disc brakes with standard ABS, side-impact door beams, GM's Passenger Sensing System, and three-point safety belts with pretentioners and load-limiting retractors.
