BMW 4 Series Coupe (2013-2020): dimensions and boot space

The length, height, width and boot space details for the BMW 4 Series: all your key measurements in one place

Sharp, sporty styling and a fun driving experience are the headlines with this version of the BMW 4 Series. This is a car that makes driving plenty of fun, especially if you opt for one of the more powerful engines.

It is not necessarily the sort of car you buy if practicality is at the front of your mind, but it’s still usefully sensible in that respect. The boot is a reasonable size, and even relatively tall passengers won’t complain too much if you squeeze them into the rear seats for relatively short trips.

And if you need a little more space in the boot or for rear-seat passengers, there’s always the four-door Gran Coupe which maintains the coupe’s sleek styling but adds rear doors and a hatchback boot opening.

Inside, the car reveals how closely related it is to the BMW 3 Series Saloon, but that’s not necessarily a bad thing as the design and operation of the dashboard is attractive, intuitive and logical. It also feels very well built.

All 4 Series models are well equipped, too, with leather upholstery, heated seats, climate control and parking sensors fitted to every car - and models built from 2016 onwards also got the option of Apple CarPlay and Android Auto connectivity.


BMW 4 Series Coupe dimensions

The 4,638mm-long 4 Series is almost identical in length to the 3 Series saloon, but it’s 1,825mm wide (or a little over 2 metres when you factor in the door mirrors) and 1,377mm tall. This makes it a little lower and wider than the 3 Series that it’s otherwise closely related to, and gives it a meaner, sportier look.

Another consequence is that you’ll find a reasonably large boot - which is fine for a couple of sets of golf clubs or a weekend's luggage - although the shape of the opening is a little awkward. There are also rear seats that are more than sufficient for average adults on relatively short journeys, though you wouldn't want to go crossing continents in the back of one.

The main rivals for the 4 Series - the Audi A5 and the Mercedes C-Class Coupe - are almost identical in size and shape, although the C-class is a centimetre or two taller and longer. The Ford Mustang, by contrast, is far larger - 15cm longer and 9cm wider.

All coupes of this type suffer from less-than-brilliant visibility, particularly when looking over your shoulder, owing to the shape of the bodywork at the rear of the car. However, the BMW offers rear parking sensors as standard, making challenging car park manoeuvres much less daunting.

BMW 4 Series Coupe boot space

The boot of the BMW 4 Series is actually quite large, with 445 litres of available luggage space. That means it’s only around 35 litres smaller than the boot in the 3 Series saloon, plus you can fold the rear seats down to accommodate longer loads.

If you want more practicality, the Gran Coupe offers the flexibility of a hatchback boot opening and 480 litres of boot space, which jumps to 1,300 litres when you fold the rear seats down.

That said, the equivalent-age Audi A5’s 465-litre boot beats the regular 4 Series, even if the 4 Series can provide more room than the 400 litres on offer in the boot of the Mercedes C-Class Coupe.

BMW 4 Series Coupe towing capacity

A sleek two-door coupe isn’t perhaps a natural car for towing duties, but the 4 Series isn’t without capability in this area. Depending on the engine, the 4 Series is rated at carrying a braked trailer of between 1,600kg and 1,800kg.

This means that the 4 Series is able to tow a reasonably weighty trailer or caravan and offers extra traction if you go for one of the xDrive four-wheel-drive versions. For regular towing duties, though, a larger, heavier car such as an SUV like the BMW X5 would make more sense as a tow car if you plan on regularly pulling big weights.

Kerb weight is how you most realistically measure how heavy a car is. It includes all the engine’s lubricants and fluids, plus a tank of fuel and an extra 75kg that is the rough equivalent of the weight of a driver and a few items of luggage.

In the case of the 4 Series, its kerb weight depends on the engine and whether or not it has four-wheel-drive (with more complex four-wheel-drive systems proving heavier than two-wheel drive setups). The trim level also has an effect. As a result, the 4 Series ranges from 1,431kg for a 420i SE manual, to 1,695kg for a four-wheel-drive 435d xDrive automatic.
