Classic Team Lotus remained involved throughout the project, and Clive had one key stipulation. “I said if you’re going to do it, it really needs to be faithful to Colin’s drawings and, while you have the opportunity, and certainly Colin would have taken it, to use all the modern technology underneath.” And then started the debate about where to draw the line between originality and modernity. In the end, that delineation was drawn between what you can see and what you can’t. Outwardly, the Type 66 is true to the car that could have raced in 1970. Under the skin, it’s all new.
Lotus innovation is apparent at first glance. Side-mounted radiators, borrowed from the Type 72 F1 car, would have been unique at the time, as would its front wing. And that aero had function to match its form. “We’ve now done over 1,000 hours of CFD work on it to make sure it all performs correctly,” says Simon Lane. “It develops just over 800kg of downforce at 150mph.”
Clive Chapman adds: “It’s pretty much a Lotus Type 72 Can-Am car really with the side-mounted radiators, front wing which was a unique feature for a Can-Am car back then, so aero wise with the big tail as well it was going to be unique so really important to capture that. We wanted to really represent the car as it was going to be on the outside, particularly because the aero was so interesting.” The period appearance continues in the cockpit. Smiths instruments with the rev-counter rotated sideways look the part, as does the wooden-knobbed gearlever that gives the impression of an H-gate.
When it comes to the bodywork, the old-school look is only as deep as the Gold Leaf-inspired paintwork. Scratch through that, though, and you’ll discover that the bodywork is made from carbon-fibre. Keep burrowing and you’ll uncover an extruded and bonded aluminium chassis akin to those of Lotus road cars. Driver aids also come within the scope of the updates. “We had a big debate [about the gearbox],” says Lane. “Do we put an H-gate in and stay faithful to the original car, or do we put a sequential in? We all agreed that, because it’s a track car and because it has so much power and so much potential performance, actually it’s going to be a lot more fun to drive with a sequential gearbox.”
