A Porsche Panamera is already a very appealing option for those looking to get into a high-end sedan (or four-door sports car, if you prefer). For those looking to take their Porsche to supercar status, though, TechArt’s new GrandGT customization program takes a Panamera and makes it even more dramatic, and individual. And even better looking.

The German tuner gives the Panamera a wide body kit consisting of a front splitter, side skirts, a rear diffuser, a sport exhaust system that includes a quartet of carbon-fiber-trimmed tailpipes, and an eye-catching rear trunk spoiler.

Customers can change up the GrandGT package even more by opting for a carbon-fiber hood and/or 22-inch Formula IV alloy wheels that are painted to match the color chosen for the bespoke Panamera.

TechArt boosts the interior by adding a blend of Alcantara and leather upholstery combined with either piano lacquer or carbon-fiber trim facets. Just like the exterior, the interior includes the option of choosing from a wide range of interior color options.

A Porsche Panamera starts at $78,000; the final kit and installation price for a TechArt GrandGT version may be obtained from the company or dealer.
