Getting comfortable in the front of the BMW isn’t a problem. All models have electrically adjustable seats – that slide effortlessly to your preferred position – and a steering wheel that has a wide range of adjustment for height and reach. You get a front-centre armrest fitted as standard and adjustable thigh support. However, BMW cheekily charges you £265 to get adjustable lumbar support on both front seats. It’s worth paying for mind you, just to ease backache on long drives.
Access to the two back seats is awkward without rear doors and you have to hold a button to slide the front seats forward electrically, rather than just pressing it once. Once you’re seated, headroom isn’t great – it never is in coupes – but passengers under six-foot tall will fit, and they’ll have plenty of knee room. In fact, the BMW’s rear seats are roomier than you get in the Mercedes C-Class Coupe, Audi A5 or Lexus RC.
Getting a child seat fitted in the back is as easy as you could hope for from a sport coupe. The front seats move right out of the way (slowly), leaving a big gap to line the base up with the easy-to-locate Isofix points, letting you slide the top of the seat into place.
Interior storage is generous. The BMW’s front door bins are each big enough for a 1.5-litre bottle of water, and the glovebox can swallow a one and a 1.5-litre bottle at the same time. You also get a couple of cupholders in front of the gearstick and a smaller lidded storage area that is ideal for change. The only annoying thing is the lidded cubby under the front centre armrest – all its space is taken up by a phone cradle that you’ll probably never use.
The BMW’s 445-litre boot capacity means it sits in between the Mercedes C-Class Coupe (440 litres) and the Audi A5 (465 litres). It’s not quite as easy to load as the Audi but because all 4 Series models come with run-flat tyres, you get a large hidden storage area under the boot floor where you would otherwise find a spare wheel.
The BMW’s boot is big enough to easily swallow a baby stroller with a couple of soft bags, or a set of golf clubs. Packed full, it can take two large and one small suitcase. Rear seats that split 60:40 come as standard. Or, for £170, they can split 40:20:40 and be released (with a shove of encouragement) from the boot, leaving a flat floor and space for a bike with just one of its wheels detached.
