Volvo introduced the PV444 in 1944, yet it only entered production for the 1947 model year. The PV444 was a series of compact unibody cars created by Volvo to be simple, fuel efficient cars that would secure the company's future. These new cars were available as two door fastback sedans. Over the course of production, the PV444 was offered with a 1.4L or 1.6L inline four engine. The PV444 was built until 1958, and was replaced by the Volvo PV544.
