The chassis was a multi-tubular spaceframe, of similar design to the 1962 Lotus 22 Formula Junior. A {{convert|997|cc|abbr=on}} Ford Cosworth 105E with Single Choke Weber or SU carburettors produced {{convert|97|bhp|kW|0|abbr=on}} at 8000rpm.{{cn|date=September 2015}} The 31 had little success against the more advanced monocoque cars that dominated in 1964. Records show only 12 were built in 1964/5. In 1966 19 cars were built with the Chassis 22/F3. The relative simplicity and low price of the car made it an ideal training car. Motor Racing Stables at Brands Hatch ran four cars to graduate students from Lotus Cortinas. The Jim Russell Racing Driver School ran the cars at Snetterton, later being recognised as a club by the RAC. The JIm Russell School ran five 31's at Brands Hatch BARC Trophy Races in July 1967. {{Team Lotus}}{{Lotus}}{{motorsport-stub}} 2 : Lotus racing cars|Formula Three cars |
