The Hydropneumatic System
The Citroën DS hydropneumatic suspension system operates using pressurized nitrogen spheres and hydraulic fluid. This combination allows the car to lift itself and stabilize, making tire changes as straightforward as pushing a button. The system also powers the brakes, steering, and gearbox. A belt-driven pump ensures that all these components work together seamlessly.
Changing a Tire with Ease
With the Citroën DS, changing a tire is far more convenient than with conventional cars. Here’s how it works:
- Lever Activation: The driver activates a lever inside the cabin.
- Suspension Lift: The lever raises the suspension to its maximum height, propping the car up.
- Wheel Lift: The affected wheel is lifted clean off the ground.
- Easy Removal: The tire can then be easily removed and replaced.
This process requires no external jack, making it a standout feature of the DS model.
