Volkswagen has revealed a new European-market 'Eco' version of its versatile Up city car, fuelled with Compressed Natural Gas.
CNG is a popular alternative fuel option in Europe, which has a higher specific energy content than petrol or diesel.
Volkswagen’s data suggests that 1kg of CNG equates to 11.69kWh of energy, compared with diesel’s 9.86kWh or petrols 8.77kWh.
Modifications for the Up Eco include two CNG tanks with a total capacity of 72 litres (one replacing the spare wheel), while a 10 litre reserve petrol tank remains for when a CNG outlet cannot be found.
The Up Eco’s EcoFuel system also enables the use of renewable biomethane where available.
This system has been integrated entirely within the Up’s structure, with the only compromise to useable space being the lack of spare wheel recess.
Outputs for the 1.0 litre three cylinder engine are just 5kW and 5Nm less than the conventional petrol version, dropping to 50kW/90Nm.
