The Mansory Porsche Panamera by RTW Motoring image

The Californian tuner RTW Motoring has presented its own version of the Mansory Porsche Panamera, where Maserati Quattroporte’s main rival has both visual and performance upgrades.

According to the American tuner, the only reason that the Mansory Porsche Panamera has been given a new kit is to demonstrate how good it looks cruising the boulevards and freeways of Los Angeles.

RTW Motoring couldn’t decide whether the car should be white or black and ended up making two Panameras, fitting them with the complete Mansory carbon-fiber aerodynamic kit, the Mansory ECU upgrade and the Mansory sport exhaust system.

The two Mansory Panameras are now delivering an impressive 681 horsepower and 700 Nm of torque, accelerating from 0 to 100 km/h in just 4.0 seconds and stopping at a top speed of 328 km/h, compared to the old 303 km/h.

The Californian aftermarket specialists didn’t provide a price for their Panamera visual and performance upgrade but considering that everyone is too busy these days with the Frankfurt Motor Show, the kit could go by unseen.
