Won the Swedish GP in 1978, then withdrawn by team boss Bernie Ecclestone (to the fury of Gordon Murray). The only F1 car with a 100 per cent win record.

Aerodynamic Efficiency Requirements and Optimisation Project was a one-off, but we reckon with TG maths and a visit to a DIY store, we could knock up a replica.
