Fuel consumption and CO2 emissions

Updated 7/23/2018

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


gram CO2/km

litres/100 km

Certified value for the car's potential range ("up to") in km in electric mode. The value should not be interpreted as an expected range, and the range is difficult to achieve during normal driving.

If the consumption and emission data is missing then it is included in the enclosed supplement.


The capacity of the hybrid battery diminishes with age and use, which may result in increased use of the internal combustion engine and, as a consequence, reduced fuel economy and reduced range during electric operation.

The values in the above table for fuel consumption, emissions and range in electric mode 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 and reduces its range in electric mode.

The certified values for the car should not be interpreted as the expected values. The certification values are the comparative values obtained during special "EU driving cycles" (see below).

There are several reasons for fuel consumption that is higher and an electric range that is shorter than the values in the table. Examples of these include:

  • If the car is not regularly charged from the mains.
  • 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.


Extreme weather conditions, driving with a trailer or driving at high altitudes in combination with fuel quality are factors that considerably increase the car's fuel consumption.

EU driving cycles

The official fuel consumption figures and range during electric operation 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.
