2021 BMW M440i xDrive Coupe review

The past seven years have been kind to the BMW 4 Series. Introduced with a good deal of fanfare back in 2013, it has now recorded over 800,000 sales worldwide. Its success is spread across three models, including Coupe, Cabriolet and five-door Gran Coupe, as well as a range of four- and six-cylinder petrol and diesel engines, which together have managed to provide it with wide appeal.
