The number featured prominently in the Caterham Cars emblem is 7.
The number refers to the Lotus Seven, the lightweight sports car designed by Colin Chapman and introduced by Lotus in 1957. Caterham became closely associated with the model after acquiring the rights to manufacture it from Lotus in 1973.
Caterham continued developing the car under names such as the Caterham Seven. The numeral in the emblem therefore identifies the company’s defining model heritage rather than a production count or engine size.
The Caterham Seven is famous for a very low weight, simple construction, rear-wheel drive, and open two-seat layout. Although versions have changed over time, the core concept remains a lightweight sports car. The badge can be confused with a racing number, but its key reference is the Seven model itself.
