General Motors and Gravana Tuning unveiled its highly customized Saturn Sky concept at this week’s SEMA show. The Gravana Tuning Turbo Saturn Sky delivers more of what roadster buyers are looking for, including all-around performance and ’stop-dead-in-your-tracks’ design.

On the engine front, Gravana added a Hahn Racecraft 16G intercooled stage 3 turbocharger to the Saturn Sky’s 2.4L Ecotec engine, which results in 348-hp and 341 lb.-ft. of torque. Handling is enhanced by an adjustable coil-over-shock suspension system, which can lower the vehicle by as much as 3 inches. Massive stabilizer bars eliminate body roll, and 14-inch drilled and slotted front brake rotors, with four-piston calipers, pull it all to a stop.

But a concept wouldn’t be concept without exterior modifications. So the Gravana Tuning Turbo Saturn Sky sports unique front and rear fascias, bodyside panels and rear center exit exhaust.
