The vehicle had a four-cylinder in-line engine with 4.7 litres of displacement.
It developed 45 PS over a four-speed countershaft gearbox and a propeller shaft, which drove the rear wheels.
The car had a ladder frame and two leaf-sprung solid axles.
The Type D was available as a four-seat touring car or four-door sedan.
