The Lotus Eleven began production in 1956. The 'Eleven' was Colin Chapman's next evolution of phenomenally successful sports cars. The vehicle was dubbed 'Eleven' because it was the Mark XI and due to its 1100 cc engine capacity. The Eleven was built in three variations. The 'Le Mans' version featured a deDion rear axle and Girling disc brakes. The 'Club' version had a normal rear axle and drum brakes. The 'Sports' version was basically a 'Club' variant with a Ford 10 engine. The rest of vehicles were identical.
The Louts Eleven has been credited with securing Colin Chapman and Lotus in the history books as one of the greatest sports car manufacturers of all times.
The Eleven was a new vehicle, meaning its design and chassis did not borrow from previous models. A steel-tubular space-frame and stressed aluminum panels were used. The chassis alone weighed less than seventy pounds. The aerodynamic body was designed by Frank Costin and was hand made from aluminum.
This followed Collin Chapman's weight saving, effect, and scientific design principles.
The Climax engine was planted in the front of the vehicle. The 1100cc was capable of speeds in excess of 140mph. The famous race car driver Stirling Moss and 'Max' Fraser set closed-track world speed records at Monza running 143 mph.
