 The 22 chassis was later reintroduced several times, although modified, as other "new" Lotus models becoming first the Lotus 31 F3 car in 1964 and then, most famously, the Lotus 51 in 1967, the first Formula Ford race car created for the Jim Russell racing school in England.The Lotus 22 was the car from which the Lotus 23 was derived, being essentially a two-seat 22 widened in the middle but using the same front and rear suspension and gearbox as the 22.The 23's introduction at the Nürburgring 1000km in 1962 was made legendary by Jim Clark, who led many laps in the tiny 1,000-pound 23, with only a engine, against cars with many times the displacement, at one point leading by a minute or more in the wet.
