Conventional valve gear had improved, superseding the former advantages of the Daimler-Knight sleeve-valve technology.

[1] The Great Depression of the 1930s was well established and Daimler, responsible for economical BSA three-wheelers and, from 1931, the mid-price Lanchester range, went downmarket to assist sales in the austere times.

The head carries the valves and rocker gear operated by pushrods from the chain-driven camshaft running in an oil bath within the block below.

[1] The transmission consists of the Daimler fluid flywheel and its Wilson self-changing pre-selective, four-speed gearbox.

An open propeller shaft takes the power to an underslung, worm-driven back axle.

[1] The pre-selective finger-and-thumb lever for choosing gears is under the steering wheel and may be worked by the left hand.

On the radius-rod-controlled front axle they are shackled forwards, flat, splayed and held out of centre.

[1] A redesigned cylinder head and an increase in cubic capacity to 2003 cc by adding 10 mm to the already lengthy stroke was claimed to have improved performance by 10% to 15%.

The opportunity was taken to make a number of small improvements including the provision of a water pump and thermostatic control of the coolant circulation.

The top gear mechanism of the gearbox was also improved to avoid a hum when the car was idling in neutral.

[7] A number of important improvements were made to the front part of the chassis though it retained the same dimensions.
