In 1950, Volvo launched an updated version of the taxis in the 800 Series. The principal new feature was the design of the front, which now had a lower profile and headlights set back in the front wings.
In August 1958, the Volvo PV544, a more modern version of the PV444, was introduced. The changes were the most extensive since the PV444 had been presented in 1944.
The PV445 was the chassis version of the PV444, which due to its unitary construction could not be supplied in bare-chassis form. Its mechanical design and frontal appearance, however, were identical to the PV444 except for an additional bar in the grille.
As a herald of hope for peace and better times, in September 1944 Volvo presented the PV444 at the large Volvo exhibition in Stockholm. The price was very attractive - 4,800 Swedish kronor, the same that the ÖV4, Volvo's first car, cost in 1927.
In 1956, a prototype of a new passenger car from Volvo was presented. The car became known as the Amazon in Sweden and the 121 and 122S on the export market.
