was not very successful in the Swedish climate; the covered version, PV 4, was introduced in the summer of 1927. This had a Weymann body and the original design was rather ungainly. Helmer MasOlle, who had been inspired by his personal Voisin C5 when he designed the original ÖV 4, was reportedly furious about the PV 4 and would not be associated with it. By 1928 a more balanced design was introduced, with a longer bonnet and thinner pillars. The oval rear window of the original PV 4 was gradually replaced by a rectangular unit.
Between 1927 and 1929 a total of 996 cars were manufactured. Of these 694 were PV 4 and 302 ÖV 4. 251 of the covered cars were of the "PV 4 Special" model.
