The Eve (Economy Vehicle Elements) was a study in fuel economy, following an agreement with the French Government's Energy Saving Agency. Ample cargo and occupant space and comfort, safety, aerodynamics, and performance were the main ideas of the Eve. Electronics and computers controlled the engine and transmission to create optimum engine throttle openings and transmission-gear ratio. The instrumentation behind the steering wheel consisted of two graphs showing the power and fuel consumption curves. The Ere could top 104 miles per hour.
It was a prototype based on the R18. The first phase of its program was to concentrate on better aerodynamics and advanced electronics to control engine and transmission. The power pack and final drive are 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 percent better than 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.
