Citroën launched the C3 1.4i CNG in France at the end of 2005. This petrol/CNG dual-fuel vehicle reflects the Marque's commitment to developing vehicles running on this type of fuel. 

Natural gas is a fossil fuel. It is abundant, economical and – above all – ecological, since it produces around 20% fewer CO₂ emissions than petrol, with no sulphur oxides or lead. It is already used as fuel by more than four million vehicles worldwide. 

Simple to use, the C3 1.4i CNG runs primarily on natural gas, switching automatically to petrol mode when the gas tank is empty. In CNG mode, the car has a range of 200 km. This is far higher than the range necessary for everyday urban use (lower than 50 km on average). 

Practical and ecological, the C3 1.4i CNG is also economical to buy and to run, since CNG costs significantly less than conventional fuels. 

C3 1.4i CNG: performance, economy and environmental protection

After the Berlingo, Citroën is expanding its range of CNG vehicles with the C3.

The engine of the Citroën C3 1.4i CNG develops 49 kW (68 bhp) at 5,400 rpm and torque of 108 Nm at 3,400 rpm. 

Gas is injected directly into the cylinder head via four specific injectors. This system of multipoint sequential injection optimises consumption while delivering high levels of performance and driving pleasure. 

The C3 1.4i CNG is easy to use. It runs primarily on CNG. The 14 m³ (11.2 kg) gas tanks increase vehicle range by an additional 200 km, for a total of more than 700 km.

The engine switches automatically to petrol mode when the gas tank is empty. The petrol tank maintains a capacity of 47 litres.

Consumption is equivalent in either CNG or petrol mode, but CNG is more economical, since natural gas is cheaper than conventional fuels. 

CO₂ emissions are 23% lower in CNG mode: 119 g of CO₂/km compared with 154 g of CO₂/km in petrol mode over a standard combined cycle.

A growing vehicle parc

Natural gas is used as fuel by more than 6,600,000 vehicles worldwide.

Europe already counts a high number of CNG vehicles in circulation, especially in Italy, with a parc of almost 433,000 vehicles and more than 600 stations, and Germany, with 55,300 vehicles and 720 stations. 

In France, heavy vehicles running on CNG are enjoying increasing success. Some 2,000 buses and 650 refuse collection trucks are already on the road, most of them in the country's main cities.

As part of a partnership with Citroën, Gaz de France is providing home supply stations for private customers living in houses with access to a gas mains (more than four million in France). Home refuelling is a transparent solution that makes the user more independent, while providing real benefits in terms of convenience and time saved.
