The 170 S and 170 D (W 136 series), the first Mercedes-Benz passenger car models to be developed since the end of the war, make their debuts at the Technical Export Fair in Hanover. Compared with the 170 V, the 170 S has a more spacious body and a standard-fit ventilation system that can be combined with a heater as an optional extra. It is also available as a Convertible B and highly luxurious Convertible A variant. The 170 D is based on the 170 V and is the first post-war diesel car. Further new products are the L 3250 truck and O 3250 bus, which herald a new era in commercial vehicle manufacture at Daimler-Benz.
