[1] The D5 did not differ particularly from its predecessor, continuing to use the same 218 cu in (3.6 L) 87 hp (65 kW) flathead straight-six engine, single-disc dry-plate clutch, and three-speed manual transmission.

On the inside, the dashboard had recessed knobs and flush-fitting gauges, as well as safety padding on the front seatbacks and "no-snag" interior door handles.

In October 1937, the D5 was replaced by the Series D8, while the Junior line models (for export and the Canadian market) were badged D9 and D10 for 1938.

[1] A modified copy of the D5's engine was produced under liecense in the Soviet Union by GAZ during the 1940s-1950s and was fitted in the manufacturer's GAZ-M20 Pobeda alongside the GAZ-51 truck.

[1] D6s as well as the D7s received Plymouth's smaller 201 cu in (3.3 L) version of Chrysler's flathead engine, producing 82 hp (61 kW) at 3600 rpm.
