The XC40 whether the B4 or T3 engine should average about 36mpg, they wont be far off. I’ve watched tons for reviews on it and they all do say the big 20 inch alloys dont make the ride worse.
The MPG is an issue and because of that I was thinking about getting the pug 2008, but there are no reliable mpg figures for that, But it uses the same platform and engines as the DS3 and the 1.2 PureTech auto only gets 40 mpg….for me thats too close to call and its the XC40 for me….lol.
