Porsche Panamera 4S by Rennsport Müller

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
