The Mercedes GL320 CDI

The GL320 CDI1 delivers remarkable fuel efficiency and power worthy of its muscular stance. The turbocharged V-6 diesel engine generates an amazing 398 lb-ft of peak torque — starting at just 1,400 rpm. And for all its strength, it still affords you approximately thirty percent better fuel economy than vehicles equipped with comparable gasoline engines.

Off-road driving program One-button off-road program allows driver to simultaneously engage programming recalibrations of the traction system, antilock brakes, engine management, and automatic transmission designed to enhance control in conditions typical of off-highway driving.¹

Downhill Speed Regulation (DSR) Driver-activated DSR automatically modulates the throttle, brakes, and ABS to maintain a preset crawl speed when descending hills. Speed is pre-programmed at 4 mph but may be adjusted between 3 mph and 10 mph via the multifunction steering wheel. DSR can be used when the gear selector is in Drive or Reverse. Driver can override DSR by pressing the accelerator or switching DSR off via its console-mounted switch.

Hill-start assist To help prevent unwanted vehicle rollback when taking off from a stop on uphill or downhill grades (15% or over), hill-start assist automatically maintains brake pressure for approximately one second after the driver releases the brake pedal. The system is automatically deactivated when the vehicle is level, the gear selector is in Park or Neutral, or the parking brake is set.
