On 17 August 1966, the Volvo 144 was presented to almost four hundred journalists in central Gothenburg. With this new model series, Volvo could develop into a considerably bigger carmaker. In eight years, no fewer than 1.25 million cars were produced – creating Volvo’s first million seller.
Back in June 1960, Volvo’s management made the final decision on the basic directive for the new car. The P660, as the project was designated, was to be larger than the Amazon, but of the same weight and price class. It was to fulfil strict safety requirements and comfortably carry four or five people. Moreover, the car was to have the same wheelbase as its predecessors, the PV 544 and the Amazon. Unlike when the Amazon was developed, several different chassis versions were planned from the start.
With the 140 series, Volvo introduced a naming scheme in which the first digit designated the model, the second digit the number of cylinders and the third digit the number of doors.
Mass production of the 144 started two days after the press presentation. In 1967 the two-door 142 was launched, and in 1968 production of the 145 estate began. A closely related model was the 164, which was launched as a 1969 model. It shared many chassis components with the 140 series, but had a 100mm longer wheelbase and a longer front to fit the straight 6-cylinder B30 engine. Yet another chassis version was launched in 1970. This was the spacious load-carrying Volvo 145 Express, on which the roof was raised from the B-pillars and back. (Read our review of the spacious load-carrying Volvo V90.)
Chief designer Jan Wilsgaard was also the man behind the Amazon’s elegant lines and, despite the differences, likenesses can be seen between the models. There was a strong desire for a grille design reminiscent of the Amazon’s. The shoulder that widened the doors below the side windows was also similar to that on the Amazon, although on the 144, this feature was even more pronounced. Like the Amazon, the 142 and the 144 had vertical tail-lights.
The 140 series was well suited to the ideals of the 1960s, giving precedence to function. It had a spacious interior and large windows. Scandinavian design, with its clean and simple lines, is a popular approach today and the 140 series is a prime example of its expression.
The 140 series entailed several important advances in both passive and active safety. The chassis was extremely resilient to twisting and was fitted with crumple zones and a protective roll cage. The brake system was advanced, with disc brakes both front and rear together with a dual-circuit system with twin hydraulic circuits at the front. This provided a three-way partitioning of the circuits, so that if one circuit failed both front brakes and one rear brake would still function. What’s more, there were reducing valves to prevent the wheels locking during heavy braking, a solution first employed by Volvo.
A split steering column and a dashboard with a collision-protected frame were other safety features. Later, the 140 series was also fitted with headrests, retractable seatbelts and seatbelt reminders as standard.
The 140 series had a conventional design with a front-mounted engine and rear-wheel-drive. Initially, the series employed the tried and tested 1.8-litre 4-cylinder B18 engine from the Amazon, producing 75bhp or, if fitted with twin carburettors, 96bhp DIN. The 1969 model had the 2-litre B20 engine, producing 82bhp and 100bhp respectively. As of the 1971 model year, there were also versions with electronically controlled fuel injection, producing 120bhp.
When production of the 142, the 144 and the 145 came to an end in the summer of 1974, 1,251,371 cars had rolled off the production line. The model series became the company’s first million seller and helped further Volvo’s position as an international player.
The legacy of the 140 series is, however, greater than this, stretching all the way to 1993. Its replacement, the Volvo 240, borrowed much from the 140 series chassis and went on to become Volvo’s most mass-produced model, with some 2.8 million cars in 19 years.
