Back in November Onyx concept gave us an early look at their GST tuning Package for Porsche Panamera with these preview images. Now they release pictures of the finished product, so we get to appreciate its proportions, and think about the fact that the Panamera is indeed a hard car to improve styling-wise.

Still, what Onyx has done here is a noble effort. The GST package includes new front bumper with mesh grille and extra vent openings, sport vented bonnet, fender extensions, side vents, side skirts, rear bumper with diffuser with new tailpipes, and a fixed rear wing.

Other parts of the program include 22-inch wheels, leather treatment for the interior, sport seats and steering wheel, carbon rims, floor mats, and two engine upgrades for the Diesel and Turbo models.

Onyx Panamera Diesel gets a boost to 350 horsepower, while the Turbo gets a full 620 horsepower.
