The enviro-friendly Volkswagen Eco Up uses a newly developed version of the 1.0-litre three-cylinder engine found in the standard Volkswagen Up, generating 50kW of power and 90Nm of torque, while consuming 2.9kg of compressed natural gas (CNG) per 100km which is equivalent to emissions of 79 grams of CO2 per kilometre.
The interior space of the Eco Up does not suffer in the CNG version as the three tanks are in the subfloor. Two are for the CNG, and the other acts as a backup and contains gasoline. This gives the car a range of 380 km (236 miles) with just the natural gas while the gasoline in the reserve gasoline tank adds another 220 km (137 miles) of driving range.
However, one of the greatest benefits of natural gas cars like the VW eco up is the fact that these models are not limited to being powered by just natural gas, but can also be powered by alternative fuels such as renewable biomethane.
Sporting two underfloor natural gas tanks that combine for a total volume of 72 litres (11kg) of (compressed natural gas) CNG, and a 10-litre petrol reserve tank, the Eco Up sees CO2 emissions reduced by 24 per cent compared with petrol engines when run on pure natural gas.
