BMW X3 (2010-2018): dimensions and boot space

Check out every important measurement you need to know about for the BMW X3, including weight, height, length and boot size

The BMW X3 is a bit of a goldilocks SUV: it’s big enough to feel suitably imposing and to provide all the space you need for family motoring, but not so large that it becomes unwieldy in the city.

Its main rivals are the Volvo XC60, Audi Q5 and Mercedes GLC. If you want the option of seven seats, there’s also the possibility of the Land Rover Discovery Sport.

Of all the various rivals, though, the X3 feels the most sporty. It’s never going to feel like a sports car - it’s just too big and heavy for that - but as a large SUV that’s still fun to drive it’s very impressive.

There are only diesel engines available in this version of the X3 (more recent models are available with both petrol and plug-in hybrid power as well), but they’re smooth, powerful and fuel-efficient.

With the exception of the sDrive18d (which is rear-wheel-drive), all X3s of this era are four-wheel-drive and are fitted with either a six-speed manual or an eight-speed automatic gearbox.

Inside there’s a well laid-out dashboard and a sense that everything’s well made. Even entry-level SE models are well equipped with leather seats and dual-zone climate control on all models, plus built-in sat-nav on SE cars from 2014. M Sport models get firmer suspension and more sporty styling, but are a bit uncomfortable unless specified with the optional adaptive suspension.


BMW X3 dimensions

At 4,657mm long, 1,881mm wide (albeit more than 2,000mm wide when you add in the width of the door mirrors) and 1,678mm tall, the X3’s dimensions are almost identical to those of its rivals, the Volvo XC60, Mercedes GLC and Audi Q5, with all of them coming within just a few millimetres.

It is noticeable that it’s shorter than the BMW X5 that was on sale as a new car around the same time, though. That car’s 20cm longer and 10cm wider, so if this generation of BMW X5 is a little too big for you, this version of the X3 might be just right.

Plus, while it’s roughly the same size as a BMW 3 Series saloon, it feels more spacious inside, mostly thanks to its higher roofline and boxier shape.

BMW X3 boot space

There’s 550 litres of space inside the boot of the X3 with the rear seats in place, and it’s well-shaped, with a low load lip and a wide-opening hatch. Fold the rear seats down and space grows to a total of 1,600 litres. The seats can also be partially folded, with the seatbacks splitting and folding three sections, so you can combine long loads and rear-seat passengers.

All that being said, the boot space in the X3 is no bigger than you’ll find in the boots of its main rivals, the Audi Q5 and Mercedes GLC. It is more spacious than the Volvo XC60, however. For its length, the X3 offers a decent amount of room, making it a usable family car.

BMW X3 towing capacity

The X3 makes for a good towing workhorse, as it’s relatively large, heavy and stable enough to make a good towing platform, and - provided you get one with four-wheel-drive - is great for hauling horseboxes or caravans out of muddy fields.

It’s also rated to tow quite a chunky load; a braked trailer of up to 2,000kg for all models except the top-of-the-range 35d, which can haul an impressive 2,400kg.

BMW X3 weight

The kerbweight of the BMW X3 includes the engine’s lubricants, a full tank of fuel and an extra 75kg, which is supposed to represent the weight of a driver and a little luggage.

The X3’s weight depends quite a lot on its specification. The rear-wheel-drive sDrive18d SE is the lightest model in the range, and comes in at 1,660kg. Meanwhile, the four-wheel-drive xDrive35d M Sport with its larger engine and a significant haul of extra equipment comes in at 1,860kg, a full 200kg more.

The most popular model in the range, the xDrive20d, sits somewhere in the middle of that, at 1,715kg, so this is the kind of weight you can expect from most X3s.
