Gravana Tuning has collaborated with GM Design to create a turbocharged Saturn Sky concept for SEMA. Gravana is a highly regarded supplier of aftermarket accessories, and the company has added several high-end accessories to push the Sky’s 2.4L Ecotec engine beyond 300hp. The addition of a Hahn Racecraft 16G intercooled stage 3 turbo, custom 3-inch downpipe and center exit exhaust allows for a total output of 348hp and 341lb-ft. of torque.

To round out the package, Gravana has enhanced the handling of the Sky with an adjustable coil-over-shock suspension system that can lower the vehicle by as much as 3in. Further, body roll has been minimized 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,

Exterior modifications include new front and rear bumpers and 19in OZ Superleggera III racing alloys riding on Goodyear Eagle F1 tires. The inside hasn’t been forgotten, thanks to the addition of Katzkin leather and suede trim plus a Boston Acoustics and Visteon entertainment package.
