The Volvo TP21 was a series of military SUVs introduced in 1953. The TP21 was based on the Volvo PV800, and was built in a lifted four door sedan body heavily drawing from the PV800. These four wheel drive cars were powered by a 3.6L inline six engine that was paired to a 3 speed manual transmission. Production of the Volvo TP21 was limited, with just 720 examples built when the model was discontinued in 1958.
