1957 Lotus Seven

The Series 3 (S3), launched in 1968, took things even further by introducing a wider track and more powerful engines. This version marked a significant step forward in terms of comfort and performance, making it more suitable for both road use and competition. The S3 also adopted a more refined design, though it still retained the raw, minimalistic nature of the original Seven. 

Finally, the Series 4 (S4), introduced in 1970, was the most radical departure from the original formula. It featured a redesigned fiberglass body, which improved aerodynamics and reduced drag. However, the S4 was not as well-received as its predecessors, as many enthusiasts felt that the heavier fiberglass body took away from the car’s lightweight appeal. Despite this, the S4 continued to find a niche among drivers looking for a more comfortable and visually appealing version of the Seven. 

The Seven’s racing pedigree began almost immediately, with its lightweight frame and simple mechanics allowing drivers to compete effectively in various motorsports categories. Notably, Brausch Niemann achieved 127 mph at the 1962 Natal Grand Prix, showcasing the potential of the Seven in speed trials. The car was particularly successful in club racing, where its affordability and performance made it accessible to a wide range of drivers. Over the years, as engines became more powerful, the Lotus Seven adapted, with models featuring Cosworth engines and improved aerodynamics, allowing it to keep up with more powerful competitors. Its simple but effective design gave it a cult following in racing circles, with many drivers finding that the Seven could outperform much more expensive sports cars on the track. 

In 1973, Lotus sold the rights to the Seven to Caterham, which continued production and development. The Seven’s design has since remained largely unchanged, with Caterham maintaining its status as one of the most beloved lightweight sports cars in history. Even today, Caterham Sevens continue to be raced, providing proof of Colin Chapman’s timeless design and the car’s enduring legacy in motorsport.
