BMW 4 Series Gran Coupe 420d 2021 UK review

We drive the second generation of BMW’s posh hatchback on UK roads It’s the second generation of BMW’s four-door version of the two-door version of a four-door car.The 4 Series Gran Coupé might have seemed like a strange concept when it first came out and the jury is still out on whether it merits the term ‘coupé’, but fact is that enough people were seduced by the original’s combination of coupé looks and near-estate practicality. As there’s a new 3 Series and a new 4 Series, it was only natural that there would be a new 4 Series Gran Coupé. Like its siblings, the Gran Coupé has grown significantly compared with its predecessor: it’s 143mm longer, 27mm wider and 53mm taller. In fact, it’s a bit bigger in every direction than even the 3 Series. Although its luggage capacity is 10 litres smaller than a 3 Series saloon's, the hatchback does make it a much more practical proposition. The sloping tailgate means that owners of large but claustrophobic dogs will still want to go for an estate, though.The floor is also not completely flat and having D-pillars that need to house hinges and lifters for the electric tailgate introduce some pretty big blind spots.
