AEC-produced steering and pre-selective transmission units were included, as were air-pressure brakes.

The car had a four-cylinder, 4.2L engine, with a three-speed selective transmission and shaft drive.

The light-weight demountable shells designed by him were the first engineered to use selective transmission of energy into the stage house and stage-house coupling to enhance on-stage and audience-area acoustics.

The car used a two-cylinder Spacke air-cooled engine, and featured three-speed selective transmission and a double chain drive The Davis was similar to the French Bedelia ( cyclecar ) in that the driver sat in the rear seat.

This bus ( UMA370 ) is preserved by the Greater Manchester Transport Museum and is also of interest as the first double-deck bus with an electrically controlled direct-acting epicyclic gearbox, this Self-Changing Gears ( SCG ) unit was fitted by Atkinson after delivery but before entry into service as the SHMD board's drivers ( who were used to pre-selective transmissions on the fleets'standard Daimlers ) did not want to use the originally installed David Brown constant-mesh unit.
