With the introduction of the six-cylinder PV650 Series in 1929, Volvo had a car large and robust enough to be competitive on the lucrative taxicab market.

The car was built in two versions: the TR S (Stad, “town”) had a glass partition between the driver and the passenger seats.

This car also had a higher roof line, so that the gentlemen wouldn’t have to take off their top hats during the ride.

Total production of TR671/672: 200 cars In April 1934 the taxicabs were updated with a new, stronger chassis with an X-shaped cross member support, smaller 17-inch rims and an all-steel body, without the wooden frame.
