Also known as the AIRMATIC air suspension, the "hydraulics" in the full-sized GL serve not only function but also serve to impress. It might give your passengers the "what the hell?! Did the car just lower itself?" reaction, when it bows down like a properly trained pup as you get out of the car, but when you're driving, it is actively adapting to conditions for the most appropriate and comfortable ride. Using electronically controlled air springs, the car can be raised for additional clearance or will automatically lower itself at high speeds for better aero. It even compensates when the car has additional passengers or cargo to ensure a level drive.
