How to use the data table

Vehicles that meet the Euro 5 and Euro 6 Emission Limits (Current Standards)

In using the table of information, it may be helpful to note the following:

  • Models are listed under the name of the manufacturer or importer.
  • The figures are obtained by running an example of the listed vehicle over a fixed route in a laboratory on a rolling road under closely controlled conditions. The test cycle is described elsewhere in this guide.
  • The results of the fuel consumption tests are shown both in litres per 100 kilometres (l/100km) and in miles per gallon (mpg). A conversion chart and conversion factors are given at the end of this guide.
  • CO2 emissions are shown in grams per kilometre (g/km). The other results of the exhaust emissions test are shown in milligrammes per kilometre (mg/km).
  • The cost of driving 12000 miles is calculated using the official combined fuel consumption figure and fuel prices which are assessed each year. Currently they are 112p/litre for petrol, and 118p/litre for diesel and 61p/litre for LPG (no fuel figures are available at this time for CNG). The electricity cost of driving 12000 miles is calculated using the electric energy consumption and an electrical cost per unit price, also assessed each year, currently this is 14.1p/kWh. A description of the calculation can be found in the Glossary of Terms. Note that, as indicated above, the official fuel consumption figures, and hence these cost figures, are for comparative purposes and actual fuel consumption and cost on the road may vary from this.
  • The external noise emitted by a car is shown in decibels as measured on the A scale of a noise meter (dB (A)). The A scale was devised to 'weight' the reading of a noise meter so it more closely represented what is heard by the human ear. The noise test is described in more detail later in this guide.
  • Important Note. Some cars may appear in more than one Euro Standard. The reason for this is that different specifications of the vehicle model in question have been approved to different exhaust emissions limits (e.g. Euro 5 or Euro 6). Changes in exhaust emission levels do not necessarily result in a change in model description. The presence of a Vehicle Identification Number (VIN) in the model description or the year of manufacture indicates the point from which a given vehicle met the Euro standard in question. If you select a car under a given Standard make sure that the dealer understands that you require a car approved to the limits applicable to that Standard.
  • It is also important to note that test figures shown in the guide are for comparison of different models and will not necessarily be the same as the fuel consumption, emissions levels, or noise levels actually achieved on the road. For this reason it is not advisable to rank a number of vehicles for which very similar figures are quoted.
  • The test to test variability in type approval local pollutant emission figures means they are of only limited value in comparing vehicles and caution should be exercised when considering these figures. More detail is given later in this guide.

CO2 Information - The CO2 figures shown are representative of the vehicle tested and may vary between specifications (variants or versions) of a given model. As such the figures are indicative only.
