Some cars leave a paper trail; the Lotus 24 left a name and a place in Lotus's list. What follows is what can be said with a source behind it. Its designer of record is Colin Chapman.
The story
The Lotus 24 was a Formula One racing car designed by Team Lotus for the 1962 Formula One season. Despite some early success in non-Championship Grands Prix, it was eclipsed by the technically superior Lotus 25 and rarely featured in the points in World Championship races.
Its place in the line
Where it sits in Lotus's history is not in doubt: the 21 came before it; the 25 followed it. Nearby in the Lotus catalogue sit the Lotus 100T and the Lotus 101.
