The Lotus 44 was an open-wheel Formula 2 racing car, designed, developed and built by the British motorsport team and constructor Lotus.
It was powered by the 997 cc (60.8 cu in) Ford-Cosworth SCA four-cylinder engine.
The car got the wide suspension of the Lotus 41, which was successfully used in Formula 3 in the same year.
Jim Clark and Peter Arundell were only able to achieve partial success with the car.
Team Lotus entered two cars in the F2 section of the 1966 German GP for Pedro Rodriquez (#31) and Piers Courage (#32), and the Ron Harris team entered a 44 for Gerhard Mitter (#30).
