According to Lotus publicists the 73 was the F3 answer to the F1 World Championship winning 72. It was built purely for use as a works car and was officially designated a “John Player Special”. Early design work was by 72 designer Maurice Phillippe before he left Lotus and it was originally intended to be a F2 car. The design was finalised by Dave Baldwin and Martin Wade. Like its F1 big brother the 73 had a bathtub monocoque with the engine acting as a stressed member attached via a tubular framework. At the front a tubular sub frame carried the rack and pinion steering, inboard front brakes, rising rate suspension with fabricated double wishbones with outboard coil springs and dampers. Rear suspension was via a single upper link, twin parallel lower links and twin radius rods, the whole design was based on the 59/69 series. Coil springs/dampers were outboard, brakes inboard.
Early season results were good with Trimmer winning at Mallory and coming second at Monaco but ultimately the car was too complex to be set up quickly in the short F3 race days and the car faded as the season progressed. Additionally the impression was that Lotus weren’t really interested in F3 and that some of the JPS F3 budget ended up in the F1 coffers.
A modified version, the 73B was prepared for 1973 but lack of a sponsor meant Lotus never raced it. The cars were sold to Dr Joseph Ehrlich in 1975 who entered one in a race at Monza as an Ehrlich-Lotus, driven by Patrick Neve, it retired after failing to feature.
