    LR Air Suspension

    hi all,

    Just pondering the question - apart from the range of LR's incl the D4 and RR, does any other manufacturer of make or model sell an air suspension 4wd or is LR the only one. I think most have moved over to coil suspension, some still retain leaf springs but is LR the one and only manufacturer offering air suspension? I think most have also moved from solid axle to independent suspension? Am i correct in assuming this? thanks

    Not sure how this compares to the D4

    From the Jeep website found this blurb about their air suspension system - has 5 settings, see below.

    The Quadra-Lift system features five height settings for optimum ride performance, each with its own benefits.

    - Normal (NRH)
    The standard ride height and is best for all-around driving conditions. It offers 8.1 inches of clearance and provides the most comfortable balance of ride and handling. The vehicle height will change automatically from Off-Road 1 to Normal when vehicle speed exceeds 50 mph. The vehicle height will change automatically from Aero to Normal when vehicle speed drops below 25 mph, or when vehicle speed is less than 60 mph and the user changes the Selec-Terrain switch from "Sport" to "Automatic".

    - Off-Road 1 (OR1)
    Provides 1.3 extra inches (9.4 inches of clearance) for off-roading, but allows a bit more suspension comfort. This position provides a good balance between ground clearance and ride comfort. This position should be the default position for all off-road driving until OR2 is needed. A smoother and more comfortable ride will result. Press the "Up" button once from the NRH position while the vehicle speed is below 48 mph (77 km/h). When in the OR1 position, if the vehicle speed remains between 40 mph (64 km/h) and 50 mph (80 km/h) for greater than 20 seconds or if the vehicle speed exceeds 50 mph (80 km/h), the vehicle will be automatically lowered to NRH.

    - Off-Road 2 (OR2)
    Provides the maximum ride height of 2.6 extra inches (10.7 inches of ground clearance) for the highest clearance over obstacles. This position also provides the best approach, departure, and breakover angles. To enter OR2, press the 'Up' button twice from the NRH position or once from the OR1 position while vehicle speed is below 20 mph (32 km/h). While in OR2, if the vehicle speed exceeds 25 mph (40 km/h) the vehicle height will be automatically lowered to OR1.

    - Aero
    Lowers the vehicle just over a half inch to maximize aerodynamics and fuel economy at highway speeds. This position also reduces body roll and provides a "sportier" feel. The vehicle will automatically enter Aero Mode when the vehicle speed remains between 62 mph (99 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to NRH from Aero Mode if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h). The vehicle will enter Aero Mode, regardless of vehicle speed if the Selec-Terrain™ knob is turned to the "SPORT" position. Turning the Selec-Terrain™ knob to the "AUTO" position will return the system to normal operation.

    - Park
    Lowers the entire vehicle 1.5 inches below normal height to make loading and unloading people or cargo much easier. To enter Park Mode, press the "Down" button once while the vehicle speed is below 25 mph (40 km/h). Once the vehicle speed goes below 15 mph (24 km/h) the vehicle height will begin to lower. If the vehicle speed remains between 15 mph (24 km/h) and 25 mph (40 km/h) for greater than 60 seconds, or the vehicle speed exceeds 25 mph (40 km/h) the Park Mode change will be cancelled. To exit Park Mode, press the "Up" button once while in Park Mode or drive the vehicle over 15 mph (24 km/h).

    A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

    LR Air Suspension

    Trucks, buses everywhere have air suspension.

    Take a look on YouTube at Oxmanagain has recently taken apart an air strut. Simple robust principle and operation and interesting piece of kit.

    Before I bought my D4 in 2013 I was looking at the Audi too and it was an optional extra then.
