Innovations.
Citroën were innovators in automobile design. Their "Traction Avant" (pictured) had the first mass production of three revolutionary features that are still in use today. They are: a unitary body with no separate frame, four-wheel independent suspension, and front-wheel drive.
Later on, in the 1950s, Citroën developed a remarkable type of suspension. A high-pressure hydraulic system was used in over 9 million Citroën cars. They included the DS, SM, GS, CX, BX, XM, Xantia, C5, and C6. Self-levelling is the principal benefit – the car kept a constant ride height above the road. It adjusted to the passenger and cargo load, and gave a very soft suspension. This type of suspension smooths out road irregularities without disturbing the occupants. It is often compared to riding on a 'magic carpet' for this reason.
