CITROEN AA 4x4VEHICLES

CITROEN'S EXPERIENCE

It is well known that CITROEN is behind many technological breakthroughs that are the basis of automo-biles as we know them today and that it has gained considerable industrial experience.

In the past fifty years, few companies have been so constantly renowned.

Mr Andr6 CITROEN, the forerunner of front wheel drive, built the first vehicle with unbeatable road hol-ding qualities in 1934. Nearly all the European vehicles currently use this technology and the American construc-tors will adopt it in a big way in the years to come. Consequently, it is logical that CITROEN is the leading specialistin homocinetic transmissions. lt is worth noting that the homocinetic transmissions problem is fundamental to thefou r-wheel drive cross-country vehicle.

Soon susceptible to the vehicles' suspension and it is corollary problems, i.e. roadholding and com-fort, CITROEN inovated yet again by commercialising, first in 1948 then in 1955, the two types of-suspensionfor which it is renowned ; -the large wheel clearance type suspension used on the 2 CV then the hydiopneu-matic suspension used on the DS. lt is worth remembering that up until now the former has been fitted onto7 million vehicles which have been driven the world over and which have superceded a fair number of so caFled < cross-countrv ) vehicles,

Once again CITROEN is one of the few constructors today proposing a robust air cooled engine with lowpetrol consumption and a reputed long life.

The problems associated with field vehicles are not unknown to CITROEN for in 1931 they designed thevehicles for the ( CROISIERE JAUNE > a 12.000 kilometers rally which crossed the Himalavas and the Gobidesert while the world looked on enthusiastically.

CITROEN has taken part in many other expeditions since then, notably in the East and in Africa and theyhave confirmed CITROEN'S original ideas as regards cross-country vehicles.

THE OUALITIES OF THE A 4 x 4

WHAT OOES ONE EXPECT FROM A FOUR WHEEL DRIVE VEHICLE ?

TO DRIVE ANYWHERE WITHOUT PROBLEMS WHILST CARRYING THE MAXIMUM LOAD ASFAR AS POSSIBLE, IN REASONABLY COMFORTABLE CONDITIONS AND AT MINIMUM COST.

TO GO ANYWHERE WITHOUT PROBLEMS...

Too often one forgets that a cross-country vehicle runs on roads suitable for traffic 80 yo of the time andthat an acceptable behaviour on highways is therefore indispensable. This is where CITROEN'S excellent indepen-dent Jour-wheel suspension is well at home and the maximum speed of 100 km per hour is sufficient. One mustbear in mind that similar vehicles are of very dubious behaviour in such conditions.

_ Rough ground offering normal adherence and resistance shows up a greater number of qualitites. TheGROUNG CLEARANCI which varies from 24 cm unloaded to 19 cm fully loaded with an armoured underside onthe vehicles - without ruggedness-acting as skis, enables to clear any obstacle. The SUSPENSION, of which wehave already spoken considerably improves the adherence and enables the vehicle to progress faster than itsry"|i. Iftg_19"1! 9f steering vibration will be especially noted, even on tracks that resemble coirugated steel plate.The LIGHTNESS and the WHEELBASE of 2,3@ meters grant it a very high safety on the steepesi gradients.

The synchronised passage from 4x2 to 4x4, a fundamental element of CITROEN A A 4 x 4 vehicle.means that the maximum benefit can be drawn from the vehicle's momentum.

Finally, the A 4 x 4 superiotity is fully revealed on sandy or muddy ground as the problems encounteredon these surfaces are due to weight and the A 4 x 4 only weighs 735 kilos.

All the trials carried out show up this advantage very well.

WHILST CARRYING THE MAXIMUM IOAD AS FAR AS POSSIBLE.. .

lf one considers the power to weight rato which represents the effective power of the vehicle, one ascer-tains that the A 4 x 4 is very well placed with 0.004 CV DIN per kilo.

ln more concrete terms, a CITROEN A 4x4 vehicle with an unladen weight of 735 kilos carries400 kilos of merchandise on a floor pace of 140 x 116 cm and tows 500 kilos trailer over any surface.

With regard to the vehicle's range, its low consumption enables it to do with a full tank 400 km on roador 10 hours of cro$s-country.

IN REASONABLY COMFORTABLE CONDITIONS...

Anyone who has ridden in a field vehicle knows about the lack of comfort. The CITROEN A A 4 x 4 isstrikingly different due to its independant four wheel suspension which makes this vehicle a cut above the rest asregards comfort and vibrations in particular.

AT MINIMUM COST.. .

Apart from the cost price of the vehicle, which is one of its advantages, the calculation is simple : for400 kifos of good in the usual cross-country vehicle conditions, (e.9. running on a track in 4x4 for 20 % otthe time and in reduced 4x4 lor 5 % of the time), the A 4 x 4 fuel consumption is 10 liters per 100 km, (i.e.10 km per liter), whereas its rivals generally have a fuel consumption that is twice as great,

Finally there is the vehicle design itself, the high level of local content it allows reducing the maintenancecosts down to the minimum : maximum standardisation, simplicity of assemblies. etc.

CONCLUSIVE TRIALS

Numerous trials have been carried out by CITROEN on tracks specially designed to reproduce the tough-est four wheel drive conditions : in particular the endurance tests whith a full lodd (including a 500 kilos trailer)which proved to be entirely satisfactory,

This type of vehicle has also been shown to the French army and has undergone trials in particulary diffi-cult conditions. The experiment highlighted the exceptional crossing and maneuvrability qualities.

AN ADVANTAGEOUS MEANS OF MANUFACTURE

Apart from the performance of CITROEN A A 4 x 4 vehicle, one will remember certain advantages thatconcern the vehicle's.design in particular and that will interest the producers more than the users.

CITROEN A A 4x4 vehicles are designed so as to be made locally. Let's insist on MANUFACTURE asopposed toASSEMBLY,for CITROEN wanted to develop a simple technology for this vehicle that is easily transfe-rable and which enables a high level of local content with a very reasonable level of investment.

The production of traditionnal vehicles with a satisfactory level of local content calls for very high invest-ment which is only justified by high production levels in the order of one or several hundred thousand vehicles peranum. On the other hand, a production unit for this type of vehicles is profitable for production levels between 500and 10.000 vehicles, the investments being proportionate and thus always easily financed.

The idea of a chassis plateform on an independent body means that these vehicles can be developed veryeasily and that all developments and variations in production can be envisaged. When compared with the highlyspecialised production generally used by car builders, the polyvalence is appreciable, numerous variations and dif-ferent vehicle models from this range can be put into effect without altering the production potential thanks to alarge human participation in the production processes.
