The Duett was produced from 1953 to 1969. The name Duett was intended to signify a car that could be used either as a delivery vehicle and a sedan .
The Duett was produced in three body styles: an station wagon, a van (station wagon) and, in small numbers, a bare chassis with no body from the windshield rearward. The design is based on the Volvo PV sedan with the same engine and he same suspension. However, unlike the PV, which had a unibody design and a coil spring rear suspension, the Duett used a ladder frame with leaf springs supporting the rear.
While the Duett has been criticized as a regressive design by those who point out that the ladder-frame car was based on Volvo's first unibodied car; the use of a separate ladder chassis provided Volvo with an easy solution in their desire to produce a suitable commercial vehicle. The availability of the bare chassis also allowed Swedish coach builders such as Grip, Valbo and Nordbergs to build Duett-based pickup trucks, convertibles and specialized commercial vehicles.
The P210 replaced the P445 in the fall of 1960. It is most easily distinguishable from the PV445 by its use of a single-piece curved windshield, which it shares with the PV544. The final P210 rolled off the line in 1969, four years after the end of production of the PV544 on which it was based. The Duett was replaced by the Volvo 145 Express.
