Hi coralie he does a 20 mile commute each day motorway making up 15miles of that city driving 5 miles I’ve just spoke to him and he said he was achieving 36/38mpg for first couple of thousand miles maybe this was a mix of running car in and adjusting your driving habits. If you still feel there’s something not right take it to dealer and ask to have it checked. Hope this helps a little because they are lovely cars take care.
