Fuel consumption and CO₂ emissions
The fuel consumption for a vehicle is measured in litres per 100 km and CO₂ emissions are measured in gram CO₂ per km.

The fuel consumption and emission values in the above table are based on special EU driving cycles (see below), which apply for cars with kerb weight in basic version and without extra equipment. The car's weight may increase depending on its equipment level. This, along with how heavily the car is loaded, increases its fuel consumption and CO2 emissions.
There are several reasons for fuel consumption that is higher than the values in the table. Examples of these include:
- If the car is equipped with extra equipment that affects its weight.
- Driving style.
- If the customer chooses wheels other than those mounted as standard on the basic version of the model, as this could increase rolling resistance.
- High speed causes increased air resistance.
- Fuel quality, road and traffic conditions, weather and the condition of the car.
A combination of the examples above could increase consumption considerably.
There may be huge deviations in fuel consumption if comparing to the EU driving cycles (see below), which are used in the certification of the car and on which consumption figures in the table are based. For further information, please refer to the referenced regulations.
Note
EU driving cycles
The official fuel consumption figures are based on two standardised driving cycles in a laboratory environment ("EU driving cycles"), all in accordance with EU Regulation no 692/2008 and 715/2007 (Euro 5 / Euro 6), 2017/1151 and 2017/1153. Since the driving cycles are also used for quality control, there are stringent requirements for test repeatability. Testing is therefore conducted in a controlled manner and only with the car's basic functions (e.g. air conditioning, radio, etc. switched off). The results of the official figures are therefore not naturally representative of what the customer sees in actual use.
The regulations cover the driving cycles "Urban driving" and "Motorway driving":
- Urban driving – the measurement starts with a cold start of the engine. The driving is simulated.
- Motorway driving – the car is accelerated and braked at speed of 0-120 km/h (0-75 mph). The driving is simulated.
The official value for mixed driving, which is shown in the table, is a combination of the results from the "Urban driving" and "Motorway driving" driving cycles in accordance with legal requirements.
To determine the carbon dioxide emissions (CO₂ emissions) during the two driving cycles, the exhaust gases were collected. These were then analysed to determine the value for CO₂ emissions.
CO2 emissions and fuel consumption (vehicle gas – CNG) – for Bi-Fuel
Methane gas gram CO₂/km | 120 |
Biogas gram CO₂/km | 43 |
Mixed driving kg/100 km | 4.5 |
CNG specifications
| Type designation | Bi-Fuel |
| Power, CNG | The power is equivalent to that of petrol. |
| Emission level | Euro 6 |
Note
- There are many different qualities of gas, as well as gases with lower energy content and range.
- The fuel consumption specified above applies for combined driving. During urban driving or fast motorway driving the consumption is higher and during calm extra-urban driving it is lower.
