In combination to the aerodynamic portion in front, A.R.T. offers a triple beam headlight set with Xenon high beams, lights for day driving in LED technology and a double function unit for lighting around corners and fog lights.
Back in March we posted this topic with poor quality photos and a press release which was difficult to understand. So to make up for the makeshift work, here is a cleaner interpretation and slightly better photos.
A.R.T Tuning has put together a modest tuning program for the GL-Class. The front end receives a sporty front bumper fascia with large air openings as well as a triple beam fog lamp assembly in either xenon/halogen configurations. Also available are the Xenon headlamps with a black inner housing. Around to the side of the vehicle are side steps with integrated blue electroluminescent light strips which project over the side step when entering the vehicle. In the rear, a new bumper fascia is sculpted to fit the four 80mm exhaust tips as well as a removable center section to accommodate a trailer hitch.
A.R.T. has developed their own suspension control module which taps into the AIRMATIC system and lowers the vehicle 35mm. However, each corner can be adjusted individually down to 75mm. The only disadvantage of the system is that speed dependent ride height control is deactivated.
Although A.R.T. gives no details, they state the power and torque upgrade for the two CDI engines increases by 20%. That gives the GL 320 CDI and GL 420 CDI and extra 45 hp (to 269 hp) and 61 hp (to 367 hp) respectively while torque increases 102 Nm (to 612 Nm) and 140 Nm (to 840 Nm).
22-inch wheels and numerous interior customizations which include a 12-inch ceiling monitor which folds down and can be rotated 360 degrees, independent DVD player with SD card reader, infrared headphones and Alcantara/suede surfaces are also available.
