The most efficient petrol engines are the base 1.3-litre turbocharged offerings – both return around 46mpg. The 2.0-litre petrol engines are offered in 224, 306 and 421hp, and their consumption figures are 41.6, 34.9 and 32.2mpg respectively. The slightly heavier Shooting Brake models consume around 1mpg more across the board.
The diesel posts an impressive 56.5mpg – but first prize goes to the plug-in hybrid, which manages 282.5mpg. As ever with efficiency figures, real-world results will depend heavily on how much of your regular commute plays to the strengths of the hybrid system. Short trips where you make the most of the 44-mile electric range will yield the best returns. Charging the battery from a standard wall socket will take 5-and-a-half hours. A wallbox lowers that time to slightly less than 2 hours.
