It has an air-cooled twin rotor 588 cc (35.9 cu in) Wankel engine.

Towards the end of the production run one machine was built for development purposes with a new water-cooled version of Norton's twin-rotor Wankel engine.

When production of the Interpol 2 ceased it was succeeded by the P52 version of the Norton Commander.

Norton did not sell the Interpol 2 to the general public.
