The 18 Mk2 was produced between 1925 and 1926, with a total production of 2,500 vehicles (which includes the 18HP).

The 18 Mk2 was introduced in 1925 with a new 2,872cc engine having a bore/stroke of 73 x 114.29mm and rated at 20HP. The 18HP still remained in parallel production until 1927.

In an Autocar road test of December 18th 1925, the author wrote “The engine pulled smoothly and sweetly at all normal touring speeds ….. the central gearchange works lightly, but as is a habit of this make, we have noticed, to need a particularly long wait when changing with a double-clutch movement; single clutching is apt to produce a slight crunch as the gear goes in ….. altogether , a thoroughly roadworthy car offered at a very attractive price.”

A contented owner wrote to the factory in July 1927 ……..“It may interest you to know that last weekend I climbed Honister Pass from the Buttermere side in the Short 18 Saloon with five up. The pass is reputed to be 1 in 3 to 1 in 4 with about 12” of loose metal. It is marked at the bottom by the A.A. as being impractible for motorists.”

In 1927 the 18 Mk2 was renamed the Short 20 and the Long 20 according to the wheelbase length.
