Technical director and chief designer Smith-Clarke was fully occupied with a new factory to make Alvis's Gnome-Rhone radial engines so the 12/70 was designed by George Lanchester and it proved to be his last automobile design.

The standard catalogued four-door four-seater saloon or two-door four-seater drophead coupé bodywork was made for Alvis by Mulliners of Birmingham. It was described by a motoring correspondent of ''The Times'' as follows:The four-door body has four sidewindows and makes a comfortable four-seater; the doors have roll armrests and ashtrays and there is a central pull-down rest. The rear windows are "carried well back and allow a very fair view". The doors have slip pockets and glass louvres that conform to the body's lines. There is a cupboard in the instrument panel and the instruments and ashtray are centrally placed. There are two-way visors, independent wiper controls (left and right), a spring steering wheel and in its centre ignition, dip and switch (headlights), signalling and horn controls. There are ventilators in the scuttle, a sliding roof and a fully opening windscreen. The front seats are adjustable, the backrests will tip up and beneath them there are floor wells for the feet of the back passengers. A stabilising bumper and two horns are fitted at the front. The whole of the back panel of the car was hinged at the bottom carrying the spare wheel on its inner side and it could be made to open just past the vertical.

Road test
In a carefully worded brief portion of a full item about a 12/70 on test a ''Times'' correspondent reported in June 1938 that he considered the price high for a Twelve but that the value was there, the quietness and smoothness of running and the firmness yet gentleness of the controls. However he did comment that in view of the ordinary (sic) springing it travelled with remarkable evenness and held the road in a most stable way. 75 mph was the greatest speed in top gear. Price as tested £435, "a drophead coupé is also made at a rather higher figure".Production
A total of 741 cars was manufactured until 1940, with 121 still surviving. In 1945 the 12/70 was replaced by the modernized Alvis TA 14, but much of the 12/70 lived on in this post war model.Alvis Type II 12/70, roomier body
In September 1938 it was announced that more room and comfort had been given to the 12/70.Cars Of 1939. The Alvis 12/70. ''The Times'', Friday, Sep 02, 1938; pg. 6; Issue 48089 The lines of the car had been improved, the floor-level lowered and the body's extra length and width gave more head, leg and elbow room for driver and passengers. It was now easier to get into the back seat and all four seats had been redesigned to give better support. The spare wheel was moved outside the car and enclosed in a metal cover. Two handles were now provided to the boot door, one with a lock. Otherwise the specification remained the same, as did the price at £435 and that of the drophead coupé was now £445. The chassis alone cost £315.Gallery
