Does the BMW 750 come with chassis lifting?
2 Answers
BMW 750 models are equipped with a chassis lifting function. This model features an air suspension system, which allows for both stiffness adjustment and height adjustment. Additionally, the vehicle is equipped with an integral active steering system. The model belongs to the large luxury car category and is sold in the domestic market through imports, with no domestically produced version available. Principle of car chassis lifting: The car is equipped with body height sensors. The hydraulic suspension control unit collects data through height sensors (or manual adjustment switches in the cabin) and vehicle speed, issuing commands to raise or lower the chassis. Four electromagnetic valves inject hydraulic oil into the four shock absorbers respectively, thereby achieving adjustable body height. The higher the vehicle speed, the lower the ground clearance of the chassis. Functions of car chassis lifting: Raising the chassis can appropriately improve the vehicle's off-road capability (including overcoming obstacles and shallow water), making it a relatively practical configuration for the vehicle. Lowering the chassis can reduce the vehicle's drag coefficient (slightly improving fuel efficiency). Lowering the chassis also shortens the suspension travel, providing better lateral support and enhancing the vehicle's road performance (reducing the risk of rollover).
The BMW 750Li indeed features an air suspension system, which essentially provides chassis height adjustment functionality. When driving this car on highways, the system automatically lowers the body to enhance stability, while it can raise the chassis by several centimeters when encountering rough roads to avoid scraping the undercarriage. During my recent test drive of the facelifted version, I could manually adjust four height modes via the central control screen - ranging from the lowest 'loading mode' to the highest off-road stance, all proving highly practical. However, it's worth noting that pre-2019 models used conventional suspension, with air suspension only available on the 760 variant. When purchasing, look for the 'adaptive two-axle air suspension' specification on the configuration sheet to be certain.
