Apart from gasoline, the eco up! can also burn CNG. The engine, with natural gas flowing through its veins, has an average consumption of 2.9 kg per 100 km. At current natural gas prices in Slovakia, this means a cost of about 3.50 EUR. The typical gasoline engine requires 4.7 litres/100 km, which is about 7 EUR. Incidentally, the largest market for cars running on natural gas is Italy, and the eco up! could be a serious competitor of the gas-propelled Pandas and 500s. Under the hood, there is a new generation spark ignition EA211 engine, the more powerful of the two three-cylinder 1.0 MPI engines. When powered by gas, it reaches an output of 50 kW (68 hp) and 90 Nm, and when fuelled by gasoline it has a maximum power of 55 kW (75 hp) and 95 Nm. The gas itself is stored in two tanks with a total volume of 72 litres (11kg CNG). The third tank stores gasoline, but its volume was reduced to 10 litres. The eco up! travels about 380 km on gas and a further 220 km on gasoline.
