While the innovative Porsche Taycan continues to garner a lot of publicity, Porsche is still working to develop the formula of its iconic Panamera that was renewed last year.

TechArt, a well-known Porsche tuner, has introduced the GrandGT program for the Panamera, a muscular version of the current Panamera that conceals much more than a new and widened body kit.

The new body kit, thanks to its extended fenders, has extended the width of the Porsche shooting brake by around 2 inches (50 mm) at the front and up to 3 inches (80 mm) at the back, as well as incorporating a significant amount of aerodynamic components. Such as a front bumper with larger air intakes to optimize airflow and cooling of the brakes, skirts, or a rear spoiler and four-fin diffuser with room for its carbon fiber-clad titanium double-tailpipes.  Also, a new hood made of carbon fiber with openings that improve airflow and a completely new set of dark-colored 21-inch and 22-inch wheels.

The new engine management system, without altering the standard software, boosts the GTS and Turbo S models’ performance and torque by 182 PS (180 HP / 134 kW) and 150 Nm (111 lb-ft), respectively, and 90 PS (88 HP / 66 kW) and 130 Nm (96 lb-ft). This translates to a total of 669 hp and 770 Nm of torque in the Panamera GTS, which can now do 0 to 100 in 3.4 seconds, and 720 hp and 950 Nm in the Turbo S, which drops to about 3.0 seconds while its top speeds are now around 305 km/h (190 mph) and 315 km/h (196 mph).
