Mansory completes its 2013 Geneva Motor Show lineup with a tuning package for the Mercedes G63 AMG. Called the Gronos, this car shares its styling kit with the G500 Cabrio Speranza, and gets an amazing power upgrade to 840 horsepower.

It’s a shame then it looks so sad! Mansory’s body kit for the G-Class, consisting of revised bumpers, carbon grilles and inserts, massive fenders and side steps, and roof spoiler, not only doesn’t improve the aesthetics of the car, it runs its nice and cool proportions.

No worries though, because the engine treatment is more than make up for it. With 840hp and 1000Nm (limited) of torque on the tap you will so fast no one will have a chance to take a second look at the car.

Other bits and bobs include 23-inch wheels, and two-tone leather and suede interior in black and yellow, garnished with carbon fiber trim package.
