Introduced for the 1956 season, this lightweight Lotus competition car marked an important turning point for the company. It was conceived as a single basic model after Lotus had become stretched by a busy 1955, and it replaced the earlier Mark 9 in the line-up. The name “Eleven” quickly stuck, and it also helped establish the long-running Lotus tradition of E-named models. From this point onward, Lotus shifted away from the earlier Mark numbering for its road and competition cars.
The model was offered in distinct factory series. The first version arrived in 1956, while the later Series 2 continued the concept from 1957 through 1959 with revised engineering and a broader development path. That evolution reflected the car’s dual role as both a customer sports racer and a serious track machine. It became closely associated with Lotus’s early motorsport rise, including notable success at Le Mans and headline record runs at Monza.
Enthusiast interest in this model is rooted in its place in Lotus history: it was one of the cars that defined the brand’s lightweight, competition-first identity before the company moved into later road and racing icons. Its compact, aerodynamic form and racing achievements made it one of the most important early Lotus nameplates, and it remains a landmark car in the company’s formative years.
