BMW X3 sizes and dimensions guide

The mid-size SUV segment is awash with choice for the average car buyer, and the segment’s popularity looks set to continue to rise with ever improving efficiency and car-like driving feel.

One of the leaders in the class is the BMW X3. Testers rate it highly thanks to the strong engine-lineup, a comfortable ride and the typically-BMW interior quality.

If you’re thinking of buying an SUV for the first time, or even if you own one of the X3’s rivals and are looking for a change, our dimensions guide will help you figure out how easily the X3 will fit into your life.

X3 external dimensions

Mid-size SUVs like the BMW X3 have become very popular with buyers, thanks in part to the fact that they’re not too large to be considered difficult to drive, even in tight city driving. At 4,657mm long, it’s only 33mm longer than a 3 Series saloon.

Measuring 2,089mm wide (including the door mirrors), the X3 is identical in width to the Audi Q5. It’s worth noting that the X3 is 25mm taller than the Audi, which might make parking in low garages ever-so-slightly nerve-wracking.

X3 internal dimensions

Testers generally agree that the X3 offers plenty of space for the driver and passengers, and the bare measurements suggest there is marginally more room than an Audi Q5 can muster. Unless every occupant is comfortably over six foot tall, it is unlikely to ever be found wanting for accommodation.

Shoulder room 1,483mm/1,458mm

X3 boot space

The X3 scores further points against the Q5 out back. While the gains are minimal, the X3’s boot is 10 litre larger with all the seats are in position, and 40 litres larger when the rear bench is folded away. Thanks to the large hatchback opening, even bulky items aren’t too hard to load in, although a traditional estate car would be better still, thanks to the loading lip being closer to the ground.

Turning circle and fuel tank capacity

A turning circle of 11.9 metres is by no means cruise-liner like, but it is larger than some rivals. The Lexus NX, for example takes only 11.4 metres to perform a U-turn.

The most frugal version of the X3 is the xDrive 20d, which in official tests returns 55.4mpg. Top up the 67-litre fuel tank and a steady drive should see the X3 manage over 800 miles before needing to be refuelled.

BMW X3 towing capacity and weights

Mid-size SUVs like the X3 make for very popular tow cars, and the X3’s capacity makes it the ideal companion for both caravans and trailers. If pulling power is the absolute priority, we’d suggest choosing one of the more powerful six-cylinder diesel engines, because they are able to tow a heavier weight than the xDrive20d.
