Drive trains-Smile

The SmILE (Small, Intelligent, Light and Efficient) project was aimed at halving the energy consumption of a Renault Twingo with identical driving performance and transport capacity. The consumption of 3.4 litres/100 km (69.2 mpg) in the NEDC (New European Driving Cycle) achieved a cut in consumption of just under 50 %, the vehicle's emission values were below the EURO III emission values and the driving performance (acceleration, top speed and range) increased.
SmILE was developed for Greenpeace Germany, subcontracting for the Swiss engine developer SwissAuto. ESORO was responsible for reducing the aerodynamic drag (-34%), the weight (-150KG) and the rolling resistance (-30%).
