Citroen C4 some hydraulics in the suspension without the complexity

Citroen C4 – In 1952, Citroen introduced their first vehicle with hydropneumatic, suspension, the Taction Avant 15CV H.

In 1955 the Citroen DS, had a belt-driven, 7-piston hydraulic pump driven by the engine to pressurise hydraulic fluid not only for the suspension, but also the power steering, the brakes, and the gearbox and clutch assembly.

Somewhat complicated and certainly different.

Now Citroen has just launched their latest C4 model in Australia with their Progressive Hydraulic Cushion but it is only part of the suspension not the whole thing.

In a typical suspension the springs and shock absorbers work together to dampen the impacts but it you reach the limit it is a hard thump on a pretty solid rubber stopper. We often called that bottoming out.

The C4 Citroen adds an extra hydraulic stop, so that, at the extremities, you get an extra effort to cushion the effect.

On the safety front, a number of driving aids combine to ensure a safe driving environment using technologies that include:

  • Autonomous Emergency Braking
  • Blind Spot Monitoring
  • Active Lane Departure Warning
  • Adaptive Cruise Control with Stop & Go Function
  • Driver Attention Alert
  • Colour Head-Up Display
  • Reversing Camera with top-down 360-degree image

Citroën C4 Shine is on sale now and priced at $37,990* MLP

The front-end, with its V-shaped LED signature lighting, incorporates Citroën’s new aesthetic standards.



Influenced by the CXPerienceAmi One and 19_19 concept cars, the design highlights Citroën’s front-end signature with double-stage headlights and chrome chevrons stretched across the front of the car, extending upwards to the daytime running lights and down to the headlights, highlighting the ‘Citroën LED Vision’ with 100 per cent LED lighting technology.

Citroën LED Vision incorporates three LED modules – headlights, daytime running lights and fog lamps for a very graphic design which completes the innovative, high-tech front end.

A high, horizontal bonnet line gives new C4 a strong, robust appearance and is underscored by a front bumper using a matte black lower skirt to ensure durability.

The air intake grilles, using the macro chevron pattern first seen on Ami One and 19_19 concepts, show the attention to detail paid by Citroën’s designers.

A smooth and aerodynamic profile
New C4’s aerodynamic profile, blending soft and muscular body lines to highlight its robust character, is highlighted by the use of large 18-inch diameter alloy wheels for optimum ride and handling.

Matte black wheel arches, linked to the front and rear bumper skirts and AirbumpTM with coloured inserts, highlight the body shape while providing protection.

The unique roofline, combined with the sloping rear window and prominent spoiler, highlight new C4’s aerodynamics and show-off its visual and physical qualities.
