Volkswagen eco Up! Concept
At the 2011 IAA, Volkswagen presented an up! that sets a new benchmark in CO2 emissions of just 79 g/km thanks to its natural gas drive (EcoFuel) and BlueMotion Technology (Stop/Start system and battery regeneration): the eco up!. No one envisioned a small car with a CNG natural gas drive of this type, even though this fuel offers tremendous advantages: natural gas engines are clean and enjoy tax benefits in places like Germany. When used in the smallest vehicle class, natural gas drives, besides posting record low emissions, are significantly more economical than hybrid systems, which are too expensive for the small car segment.
Volkswagen also uses the eco up! a newly developed 1.0-liter three-cylinder. Makes the 50 kW / 68 hp. As EcoFuel version without BlueMotion Technology is already in the car next year come on the market. Average consumption: 3.2 kg/100 km natural gas (CNG = Compressed Natural Gas). This consumption corresponds to a CO2 level of the already extremely low 86 g / km. BlueMotion Technology version in the style of the eco up! consumption will decline to 2.5 kg/100 km and CO2 emissions on the said 79 g / km.
