1981 came EVE, the economy project car. Eve was a prototype based on the R18. The first phase of its programme was to concentrate on better aerodynamics and on the use of advanced electronics to control engine and transmission, the power pack and final drive being left as standard initially. Having an all-up weight comparable with that of the R18TL, it had a lower-drag body shape to give a drag coefficient of 0.239-43 per cent better than that of the average European car. Good performance was achieved with a smaller engine, the EVE version of the 18 having a 5TL engine of 1,100cc.
