High Quality Content by WIKIPEDIA articles! The Volvo PV800 Series (affectionately known as Volvo-suggan or the Sow) was a taxicab manufactured by Volvo between 1938 and 1958. The Sow dominated the Swedish taxicab market during the 1940s and 1950s.The PV801 (with a glass division between the front and rear seat) and the PV802 (without the glass division) were introduced in 1938 and superseded the TR670 Series. The chassis and body were all new but the side-valve engine was the same as in the older cars. The front end was also used on Volvo's smallest lorry, the LV100 Series.
