The single-seater model first took to the track in 1967, when it won on its debut in Zandvoort with Jim Clark at the wheel.
Designed by Colin Chapman and Maurice Philippe, the 49 holds the record of making the biggest performance stride forward compared to its predecessor of any car to compete in F1.
Its groundbreaking design centred around turning the engine into a stressed structural component, with it bolted directly to the monocoque and the suspension and gearbox attached to its rear. This basic layout is still employed today.
The engine itself was a Ford Cosworth DFV 3.0-litre V8 that produced around 415bhp. The car weighed just 501kg, giving a power-to-weight ratio of 828bhp per tonne. By way of comparison the McLaren P1 produces 584bhp per tonne.
Along with Clark, the Lotus 49 was also driven by Graham Hill, Jo Siffert, Jackie Oliver, Mario Andretti, Jochen Rindt, Richard Attwood, John Miles and Emerson Fittipaldi before it retired in 1970.
