Citroen C5

C5 is a large D-class sedan,

Among his classmates are: Toyota Avensis, Honda Accord, Audi A4 and some others.

THP 150 engine with a volume of 1.6 liters and a power of 150 hp, on an automatic 6-speed gearbox of the Japanese company Aisin.

 

For the city, this is quite enough. Peugeot 308 and 3008 cars, also produced by PSA Peugeot-Citroen, are equipped with the same engines. What is unusual about these engines? They are a special modification for countries with difficult operating conditions (large temperature fluctuations, unstable fuel quality, etc.).

 

Other engines available are another 1.6-liter naturally aspirated petrol with 120 hp. (VT i 120) and three diesel options: two four-cylinder turbodiesels - one with 140 hp. the other - 204 hp (a modified version of the previous one with modified valve timing, equipped with two turbines) and a three-liter V6 turbodiesel with a capacity of 240 hp.

 

As for the transmission, these hydromechanical units adaptable to the driving style are produced by the Japanese concern of the same name, and they were developed jointly with French engineers specifically for Peugeot-Citroen. They are also installed on Peugeot - including the 308, 3008 and RCZ.

 

Hydropneumatics

Probably the main advantage of the car is the Hydractive III+ hydropneumatic suspension patented by French engineers back in 1955. Since then, the cunning French have continued to receive their dividends from this by selling the patent to various automobile companies.

 

 

It is called hydropneumatic because the working medium in the suspension is both compressed nitrogen and synthetic oil. The liquid and gas inside are separated by a membrane, and the hydraulic pump delivers the desired pressure.

 

Shown in 1955 at the 42nd Paris Salon, Citroen DS became the main novelty of the season. The pressure at that time was regulated using a special valve, and the ground clearance remained unchanged, despite the degree of loading of the car. And most importantly, thanks to hydropneumatics, it was possible to hang out any wheel without a jack!

 

Now the improved suspension works with the help of electronic control. Now its height is adjusted both manually and automatically.

 

For manual adjustment, there are 2 special buttons on the gearbox panel, marked with up and down arrows, which allow you to change the height of the suspension in 4 positions: 10, 17, 20 and 24 cm. The lowest mode is provided for the most convenient loading into the car .

 

In this mode, the driving speed is limited to 10 km/h. The next position is 17 cm, this is the standard height of the car, suitable for driving at any speed.

 

 

20 cm is a mode suitable for overcoming various road obstacles such as rutting or difficult roads, for example, in winter with a lot of snow. Here the speed limit is 40 km/h. And finally, the highest suspension position is 24 cm, for overcoming particularly difficult obstacles, the speed is also limited to 10 km / h (as in the lower mode), and there is no damping at all

What happens if you exceed the speed limit? It's OK. The car will immediately go to "increase" or "lower", first the front part goes down, then the rear part, which is natural to maintain driving stability.

 

A sport mode is also provided here - a separate button located in the middle between the suspension adjustments. It is she who regulates the automatic activation of hydropneumatics, which occurs at speeds above 110 km / h. At the same time, Citroen lowers 15 mm in front and 11 mm in the rear. When decelerating, the car reaches normal geometry at 90 km/h.

 

 

In addition to height adjustments, the suspension also receives automatic stiffness adjustments for better control. Indeed, at high speed, the C5 behaves almost perfectly: it does not shake, there is no feeling of lethargy and loss of control over control, only smooth movement and almost no feeling of high speed remain.
