The eco take up! and eco move up! are powered by a highly-advanced natural gas engine designed for dual-fuel operation on CNG (compressed natural gas) or gasoline. With a CNG consumption of only 2.9 kg or 4.4 m³ per 100 km and a correspondingly low CO2 emission figure of 81 g/km, this model, with a power output of 50 kW / 68 PS, reaches the highest efficiency class: A+. As a result of these data, the eco up! has repeatedly been selected as the most environmentally compatible car of the year by respected German motoring organization Verkehrsclub Deutschland.
