Renault has introduced Logan Eco2 Concept to contest the 2007 Michelin-organised Challenge Bibendum in Shanghai, China. Logan Eco2 concept is eco-friendly in every sense of the word. The built car contains 8.3% of recycled plastics and is 95% end of life reusable by weight. Equally impressive are the emissions, the vehicle exhales only 97grams of CO2 for every kilometer it travels.
Logan Eco2 is powered by a 1.5dCi engine that runs on B30 biofuel and gives 85hp of power. Carbon emissions were reduced by powertrain adjustments that included longer gear ratios, re-calibration of the injection system and use of low viscosity lubricants.
Further gains were made by optimization of the aerodynamics, which led to a slippery drag coefficient of 0.29. Use of low rolling resistance tyres and reduction of energy requirements from the battery (12.8 Volts in place of 13.5Volts) help to further reduce emissions. The Eco2 concept can travel for 100km on just 3.4 liters of fuel, a remarkable figure for a five-seater sedan.
