BMW 4 Series Coupe review - Practicality, comfort and boot space
Space in the cabin is pretty good for a coupe, but the boot is a touch shallow
This is a coupe and there are practicality penalties that come with the slippery shape. The 3 Series saloon is a more practical car than the 4 Series coupe but next to its sports car peers, the 4 Series stacks up relatively well. The rear seats are roomier than you might think and there’s no issue with space for front seat occupants.
The 4 Series more or less mimics the 3 Series saloon with its 4,638mm length and 1,825mm width. That makes it a manageable size for being wieldy and manoeuvrable in tight spaces, but gives the car enough of a footprint that it won’t feel cramped inside, although of course the lower roof line does rob some headroom, especially in the back.
Leg room, head room & passenger space
When it comes to cabin space, the 4 Series is not bad. Yes, the back seats are pretty much best kept for shorter journeys, but you’d be surprised just how tall someone needs to be before they feel uncomfortable back there. The front seats are excellent though – the standard ones don’t look all that exciting when you see them, but they’re wonderfully comfy and supportive and there are lots of sportier options for extra bolstering and side support. Plus, unlike a lot of modern sporty cars, you can get the seat low to the ground for a proper sports car driving position.
It’s worth remembering that not all 4 Series models have three rear seatbelts though, which can limit the car’s practicality somewhat. OK, so you’re probably not going to expect to squeeze three people into the back often, but you never know when an extra belt set will come in handy.
There is more room in the back than in the current Audi A5 and Mercedes C-Class Coupe and a little less than you get in larger models like a Mercedes E-Class Coupe, but it’s adequate on the whole. Less good is the Convertible, which forces the rear seats into a more upright position to make room for the roof stowage. This sounds like a small thing but it makes a huge difference to comfort on a longer journey for anyone relegated to the back.
Again, of course, if you want your 4 Series to be a bit more practical you can upgrade to the five-door 4 Series Gran Coupe, which has a bigger boot, if not actually any more useable space in the back seats.
A 445-litre boot is pretty decent, but you do need to remember that it’s a little shallower than that of the 3 Series saloon and that the aperture isn’t very wide on the coupe. Folding rear seats are also not standard, so remember to tick that box if you want your 4 Series to be as practical as possible.
