Environmental Scores by Vehicle Type

We have rated each model range according to its CO2 output within its segment. The reason for categorising CO2 by segment is that an MPV like a Ford Galaxy is bound to produce more CO2 than a city car - but if you have a large family it is not very helpful to be told that a Toyota Aygo is environmentally-friendly. We have rated each model against the average for its segment, so a CO2 output of 140g/km would be very good for a large family car like a Vectra, but very poor for a city car like a Ford Ka.

Incidentally we have taken the average CO2 figure for each model range. That does not mean that every version of a model range has the same star rating (e.g. a Focus TDCi is much better than a Focus ST). However, it shows how well the model range performs overall.

For reference, these are the upper limits to earn a five star CO2 rating in each segment:
