2.4L Saturn Engine Specs

Size

• Otherwise known as "displacement," the Saturn Sky's engine is sized to move air volume through four in-line LES cylinders at 2384 cc (cubic centimeters) per engine cycle. A larger internal combustion engine gets more power because it pushes more air through the combustion chamber.The Saturn Sky's double-overhead cam shafts maximize its airflow to sports car performance standards even though its 2.4-liter size is more typical of a midsized sedan. In that sense, the Saturn Sky's engine size matters. Saturn debuted the 2.4-liter displacement in 2008.

Power

• The Saturn Sky is powered to 173 horsepower at 5800 rpm (revolutions per minute). Its double-over head cam and four valves per engine cylinder enhance the Sky's power while conserving fuel. That said, four cylinders containing four valves each work in unison to to pump plenty of oxygen into combustion. The Sky's engine power is boosted with multi-point fuel injection, so it can give you some extra "kick" (167 feet of torque). Between its design and its features, the Saturn Sky is powered to perform as a sport car.

Efficiency

• According the the US Environmental Protection Agency (EPA), the 2010 Saturn Sky returned 19 miles per gallon (mpg) in the city and 26 mpg on the highway. The EPA rates the car's combined mileage at 21 mpg. The Sky carries 13 imperial gallons per tank of fuel. Although its fuel economy may not seem exceptional, Automotive.com reports that the Saturn Sky compares favorably to its nearest competitors. It may suck more fuel for power, but engine design allows the Saturn Sky to conserve what fuel it can in the process. In the age of lean, the Saturn Sky's engine caters to both power and cost-efficiency.
