BMW X4 (2014-2018): dimensions and boot space

All you need to know about size of the first-generation BMW X4 (2014-2018) including its width, length, height and boot size

The BMW X4 is a coupe-SUV that’s closely related to the BMW X3. It has almost the same front end as that model, in fact, and the main difference between these models is the X4’s sloping rear end that gives it a sleeker look.

The model arrived in 2014 and was on sale from 2014 to 2018 in first-generation form. There is a second-generation model available, but we’re focused on the original version in this article, where we’ll dive into the car’s dimensions and weight figures in detail.

The X4 was available with three different engines, all diesel and all with four-wheel-drive. There were some manual models sold but most used versions are automatics, and many are in sporty M Sport trim - though SE and xLine versions were also available. The engines are a 2.0-litre four-cylinder diesel in the xDrive20d and a 3.0-litre six-cylinder diesel in the xDrive30d and xDrive35d models.

The X4 is around the same size as the equivalent age BMW X3, but the main alternatives are stylish SUVs from other brands including the Mercedes GLC Coupe, Porsche Macan, Jaguar F-Pace and Range Rover Evoque.

Read on to find out more about the BMW X4’s dimensions including boot space, weight and towing capacity.


BMW X4 dimensions

The BMW X4 is 4,671mm long, 1,881mm wide and 1,624mm tall, so it’s pretty much the same size as the BMW X3 it’s based on (which is 4,684mm long, 1,881mm wide and 1,675mm tall).

It’s also really similar in size to the Mercedes GLC Coupe, which is the most obvious alternative choice. That car is also 4.7m long, 1.9m wide and 1.6m tall. One thing to notice is that the X4 is lower to the ground than the X3, so it’s worse at off-roading and more suited to on-road driving - not that most owners take this type of car off-road anyway.

There’s plenty of space in the back seats, though - despite the lower roofline at the back, the X4 isn’t much less spacious than the X3 in the rear and adults should still be able to sit fairly comfortably. Visibility is significantly reduced by the sloping roof, though.

BMW X4 boot space

The BMW X4 has a nice round boot space figure of 500 litres, which is 50 litres less than you get in the BMW X3. It’s identical to the boot space figure of the Mercedes GLC Coupe, though - that car also has 500 litres of space in the back.

Fold down the rear seats and the available space increases to 1,400 litres, which is okay, but again is less than in a BMW X3 (by a substantial 200 litres). The boot hatch is pretty wide and tall, though, so access is easy, and the loading lip isn’t too big. Plus, the Mercedes GLC Coupe again has an identical amount of space inside with the rear seats dropped, so both of these models are equally practical on paper.

BMW X4 towing capacity

The BMW X4 makes a pretty good tow car as all versions are rated to tow at least 2,000kg. Models with the larger six-cylinder engine are even able to pull up to 2,400kg worth of braked trailer, and since every version of the X4 comes with four-wheel-drive, it should be easily able to handle pulling a typical caravan or trailer.

The best version for towing is the xDrive35d model, simply because it’s the most powerful and has the highest towing capacity, but even the xDrive30d version can pull the same weight of 2,400kg on paper and should be a bit cheaper to buy. Both will suffer from reduced fuel economy when towing, which is the case with any tow car, but these engines are strong and powerful.

BMW X4 weight

The BMW X4 weighs from around 1,730kg to 1,860kg according to the kerbweight figures for the car. These show the car in a representative state to compare to other models. The entry-level 2.0-litre diesel model with a manual gearbox weighs 1,730kg, while the automatic version of this car weighs 1,745kg.

Move up to a six-cylinder xDrive30d model and the weight rises to 1,820kg, while the xDrive35d model is 1,860kg. It’s also worth remembering that M Sport trim will increase the weight as well, since it comes on larger alloy wheels and has more kit on board.
