This 118bhp diesel is far less urgent when you put your foot down than the petrol, but it does have solid mid-range shove to pull the Grandland X ably enough, even when it’s fully loaded. Average fuel economy varies from 61.4mpg if you specify an automatic gearbox and the grip control system to 70.6mpg in a manual car with regular tyres, while CO2 emissions are as low as 104g/km. Unless you're a company car driver looking to keep your tax bills low, we'd stick with the petrol.
