Lotus Type 25

The Lotus Type 25 Climax was introduced in 1962 as the first monocoque chassis design in Formula 1. It featured a 1.5L Coventry Climax FWMV V8 engine producing 150 hp, paired with a 5-speed manual transmission. This open-wheel racing car was highly innovative and set new standards for aerodynamics and weight distribution in motorsport.

The Lotus Type 25 BRM variant was developed for teams using the British Racing Motors (BRM) engine. It maintained the innovative monocoque chassis but was equipped with a 1.5L BRM V8 engine, offering competitive performance in the 1963 and 1964 seasons. This variant was part of the ongoing evolution of the Type 25 platform.

The Lotus Type 25 Series 2 was introduced in 1964, featuring minor aerodynamic modifications and a revised suspension setup. It continued to use the 1.5L Climax engine but introduced improvements in handling and stability. This variant was essential in maintaining the Type 25's competitiveness in the 1964 Formula 1 season.

The Lotus Type 25 Special was a limited production variant created for specific racing events, featuring enhanced tuning on the Climax engine, producing approximately 160 hp. This variant was designed for drivers seeking a competitive edge and was known for its lightweight construction and superior handling characteristics.
