Chassis No.911 | The Borgward twin-cam engine developed by Bill Wolman.

An exceptionally rare and historically significant 1960 Lotus 18, chassis #911 — a genuine example of Colin Chapman’s ground-breaking first mid-engine Grand Prix design, uniquely associated with the Borgward engine conversion pioneered by Bill Wolman.

Introduced for the 1960 Formula One season, the Lotus 18 marked a decisive shift in Grand Prix engineering. Conceived by Chapman as a lightweight and uncompromisingly functional machine, the Type 18 established the mid-engine layout as the definitive architecture for top-level single-seater racing. Its first Grand Prix victory came in the hands of Sir Stirling Moss at Monaco in 1960, driving for Rob Walker Racing, before Innes Ireland secured the first works victory for Team Lotus. The model’s effectiveness saw it adapted successfully for Formula 2 and Formula Junior competition, confirming its importance in the evolution of modern racing car design.

Chassis #911 represents a particularly fascinating chapter in the model’s history through its period Borgward twin-cam, four-cylinder installation. Developed and championed by respected engineer Bill Wolman, the 1.5-litre twin-cam Borgward unit was admired for its robust construction and high-revving efficiency, offering a competitive alternative to the Coventry Climax engines of the era. Borgward-engined Lotus 18s were produced in very limited numbers and are documented in period racing literature, making this car a rare and highly interesting blend of British chassis innovation and German engineering.

This Lotus Type 18, chassis #911 it is fitted with the original development 1.5-litre Borgward twin-cam, four-cylinder engine with mechanical Bosch injection. Rebuilt in Italy to competitive specification with its Queer gearbox rebuilt by Setford & Company where is currently maintained and race ready. Presented in correct period configuration, substantial works have been undertaken, with all principal components crack-tested in 2022, ensuring both integrity and readiness for continued use while preserving its historical authenticity.

The car is finished in its distinctive and evocative period turquoise livery with contrasting red nose, a striking and recognisable competition colour scheme. It is offered with a small selection of race spares.

This Lotus 18 Wolman-Borgward is far more than a historic single-seater; it is a documented and unusual piece of early 1960s Grand Prix innovation. Eligible for leading historic racing events, including HGPCA fixtures, Goodwood and Monaco FIA historic meetings (subject to acceptance), chassis 911 would be welcomed on any prestigious grid. It represents a compelling opportunity for the serious collector or historic racing enthusiast seeking a rare and technically fascinating example of Lotus competition history.
