Based on the Mercedes-Benz GL420 CDI, Kicherer has announced their refinement of this rugged off-roader and called it the GL 42 Sport Black. Based on the X164 platform, the German tuner starts the upgrade by boosting the output of the 4.2 liter CDI diesel engine to 375 horsepower with a corresponding bump in torque of 664 foot-pounds. These are increases of 73 horsepower and almost 150 foot-pounds of torque from the stock ratings. A modification which Kicherer call its PowerConverter adjusts the drive-by-wire throttle’s response to improve acceleration. This acceleration boost is aided by a sports exhaust system with twin pipes on both sides at the rear. The Airmatic suspension was also tuned to provide sharper handling.
A matte black foil finish, including grille and badges are re-done in black, with a 22-inch Vogue wheel package rounding off the external makeover. 295/35R22 tires adorn the 10-inch wide rims while the interior benefits from the addition of a sport steering wheel. All in all, the modifications successfully refine the GL420 to a standard that combines the car’s original ruggedness with an understated hint of aggression.
