German racing tuner adds more power, 22-inch wheels and lowers the suspension on the all-wheel drive Panamera 4S.

German tuner Rennsport Müller has a new package out for the Porsche Panamera 4S.

The racing tuner starts things off with a little extra power for the all-wheel drive 4S. The 4.8 liter V8 engine with a standard output of 400 PS (294 kW / 394 hp) gets bumped up to 425 PS (313 kW / 419 bhp) by means of an ECU remap.

For the ride, the adaptive air suspension gets lowered by 40 mm and 22-inch wheels from Schmidt Revolution are added - 10 x 22-inch rims with 265/30R22 tires at the front and 11.5 x 22-inchers for the rear axle wrapped in 305/25R22 tires.

A sound optimization is also performed on the series exhaust system while the interior gets a complete leather finish from specialists RSM.
