Coventry Climax
Having devised the monocoque Lotus 25 for use by the works team, Colin Chapman decided to build a 'conventional' back-up spaceframe design which he would also sell to privateers. The 24 was a completely different design from its predecessor, the 21, and used much of the same suspension as the 25. Both Coventry Climax FWMV and BRM P56 engines were generally fitted, with at least one example running with the Coventry Climax FPF four-cylinder.
