Frederick Simms, Founder of the Royal Automobile Club, was interested in the practical usage and development of motor vehicles for military applications. In 1899, Simms equipped a De Dion quadricycle with a quick firing maxim machine gun and armoured shield.
This early experimental design inspired Simms to create the Motor War Car, which was created to his specification by Vickers & Sons. The armoured war car, reminiscent of a tank, was also equipped with a maxim gun.
The Motor War Car was unpredictable, costly to produce and had a long production time making it unsuitable for mass manufacture. It was finally finished in 1902 by which time the second Anglo-Boer War had already drawn to a close.
