2CV anniversary. The delivery van turns 75. Part 2: the years 1962-1969

Just under three years after the launch of the Citroën With the 2CV, the French manufacturer launched a variant for the entrepreneur. In March 1951, the 2CV AU hatched, and a production period of 27 years followed. Auto Motor Klassiek describes the history and development of the legendary van in three parts. Today we describe the period 1962-1969.

In the first half of the sixties, the Citroën The AZU and later the AK represented a quiet and visible evolution. Year after year, the manufacturer implemented targeted improvements. For instance, the braking system was modernized early on with a new master cylinder, based on that of the Ami 6, and modified brake lines.

Modifications to engine and electrical system

In terms of motor skills, it also developed Citroën The delivery van continued. Improvements included the modified oil pump, the adjusted carburetor, and more efficient heat conduction around the spark plugs. The electrical system was also modernized, with a modified alternator and starter motor. The dashboard changed and became—in all relative terms—increasingly complete. The installation of electric windscreen wipers was a definite plus; the gearbox now received a gear ratio of 8:31.

Arrival of the AK

With the introduction of the AK in 1963, Citroën a new step. This longer and more powerful variant, equipped with a 602cc engine from the Ami 6, offered a significantly higher payload (350 kilos) and thus explicitly catered to professional use. The AK was twenty centimeters longer than the AZU, and that gain in length benefited the cargo space entirely. Shortly after the launch of this new type, the version is also available as a 'Break' or 'Weekend', and suitable for transporting more than two people. In September, the AK also receives four shock absorbers all around.

Seatbelts as an option, suicide doors disappear

In 1964, seat belts were introduced as an option. Lighting and wheel technology were also addressed, including the switch to tubeless tires. A significant milestone was the replacement of the characteristic “suicide doors” with conventional, front-hinged versions, which improved both safety and ease of use. Furthermore, the smallest variant, the AZU, received a gearbox with modified gear ratios.

Return constant velocity shafts, as an option

The refinement continued in 1965, with improvements to the suspension and steering. Shock absorbers all around ensured greater ride comfort and stability, while technical details such as self-locking nuts increased reliability. At the same time, the model received a subtle visual update, with a new grille and modified bumpers. The constant velocity joints returned, albeit as an option. This is a clear plus, and offers a distinct reduction in noticeable vibrations from the front axle, especially in corners.

12 volt and new gearbox for AK350

In 1966, the AK made a significant leap with the introduction of a 12-volt electrical system, which noticeably improved the performance of electrical components. Comfort features also made their debut, such as an optional petrol heater. Small but well-thought-out changes — from a more ergonomic handbrake to improved window constructions — show how Citroën continued tinkering with daily ease of use. At the same time, ensured Citroën for better noise reduction and engine reliability. Furthermore, the AZU received a more powerful engine with 33 hp, while the AK350 was equipped with a completely new gearbox. Ergonomic improvements, such as hanging pedals and a modified heating system, brought the model closer to the comfort level of passenger cars.

Improved safety and visibility

In 1968, improved braking systems, dual brake lights, and orange turn signals appeared, among other things — a clear advancement over the earlier configuration at the time. Simultaneously, smaller technical adjustments contributed to a further refinement of the whole. During the final year of the sixties, Citroën Continuing with the order series.

The last modifications of the sixties

In the engine, the aluminium valve covers were replaced by more durable steel ones, and shortly thereafter, the braking system received a 3,5 mm spiral brake line at the rear. In July, adjustments were made to the AZU's suspension, including revisions to the shock absorbers and adjustments to the chassis ride height for improved handling. Finally, September brought several practical and production-oriented changes, such as the introduction of a steering lock. Citroën simultaneously bids farewell to headlight suppliers Marchal and Ducellier.
