The GrandGT is the latest enhancement package for the Porsche Panamera from Techart.

Modifications include both mechanical tuning and aesthetic design tweaks. The new Techart-tuned version benefits from more power than the standard Panamera Turbo it's based on - along with aggressive, assertive styling.

The GrandGT offers up an oversized body kit made of a composite. It consists of a front bumper with integrated splitter and large ventilation intakes, daytime running lights and a Techart Aero bonnet. You also get side skirts and flared wheelarches, which increase the car's width by 21mm on each side. Also included are a roof spoiler and larger rear spoiler, as well as tailpipes with a controllable bypass valve.

As for power, the standard 4.8-litre twin-turbo engine is boosted from 493- to 571bhp; this is primarily due to the Techtronic engine management system.

The GrandGT rides on either Techart Formula II design 22-inch or Formula III forged light alloy wheels in 21- and 22-inch sizes. Each is customisable in various colours.

The interior is not overlooked, with an optional entertainment package comprising of two seven-inch screens that are incorporated in a console in the front seat backrests and match the colour of the vehicle's interior.

Techart will present the GrandGT at the Zurich Car Show on November 11- 14.
