2006 Gravana Tuning Turbo Saturn


(from General Motors Press Release) Gravana Tuning Turbo Saturn Sky

Working in conjunction with GM Design, Gravana Tuning a highly regarded supplier of aftermarket accessories has pushed the Saturn Sky to the stratosphere with a highly customized concept. The Gravana Tuning Turbo Saturn Sky delivers even more of what roadster buyers want: all-around performance and stop-dead-in-your-tracks design.

By adding a Hahn Racecraft 16G intercooled stage 3 turbocharger to the Skys 2.4L Ecotec engine, the Gravana Tuning concept returns 348 horsepower and 341 lb.-ft. of torque. Road-hugging handling is enhanced by an adjustable coil-over-shock suspension system that can lower the vehicle by as much as 3 inches without changing the spring rate. Body roll is virtually non-existent with the addition of 25 mm front and 28 mm rear stabilizer bars. Massive 14-inch drilled and slotted front brake rotors, with four-piston calipers, provide additional stopping power, while a number of functional design elements serve to deliver more cool air into the engine and to extract heat from it.

Outside, the Gravana Tuning Turbo Saturn Sky complements the sleek, crisp and modern lines of the production vehicle, further enhancing its bold, cutting-edge design. Unique front and rear fascias, bodyside panels and rear center exit exhaust not to mention the OZ Superleggera III 19-inch wheels and Goodyear Eagle F1 tires give this special Sky a longer, lower, and sleek presence on the road.

Inside, the Gravana Tuning Turbo Saturn Sky features a carbon fiber console and dash inserts. The seat and door panels are finished in Katzkin leather and suede. Seven Boston Acoustics premium speakers and a Visteon eight-channel DSP 360-watt amplifier provide optimal aural enjoyment and complete the interior upgrade.
