Renault’s Eolab Concept that was introduced at the 2014 Paris Motor Show previews new fuel-saving technologies that will be seen on production cars before the end of the decade. According to Renault, the new Eolab Concept needs just 1 liter of fuel per 100 km (282 UK mpg/235 US mpg), while CO2 emissions are just 22 g/km.
For those who don’t know, the concept uses a plug-in hybrid powertrain that consists of a 1.0-liter 3-cylinder petrol engine that produces 75 hp, a 6.7 kWh battery as well as a clutchless three-speed transmission featuring an integrated electric motor. Using just the energy stored in the lithium-ion battery, the maximum range is 60 km or 37 mph.
Still, these numbers don’t make the Eolab more fuel-efficient than the Volkswagen XL1, which needs only 0.9 l of diesel per 100 km. But comparing it with the XL1, the Renault Eolab Concept is a four-door subcompact while the German rival only offers room for two and limited interior space.
In addition, Eolab Concept offers active aerodynamics such as a front bumper spoiler that lowers by 100 mm when speeds exceed 70 km/h (43 mph) as well as rear bumper flaps that open in order to retain surface contact with air that would otherwise slow the vehicle.
Renault developed the Eolab Concept in order to prepare to meet the industry goal set by the French government for the launch of ultra fuel-efficient cars by 2020 that use just 2 l of fuel per 100 km.
