BMW X4 Estate boot space, practicality and safety

2014 - 2018 (change model)
Practicality rating: 3 out of 53.0

Written by James Taylor Published: 6 June 2019 Updated: 6 June 2019

The BMW X4 hasn’t been tested by independent safety body Euro NCAP but it’s heavily based on the BMW X3, which scored five stars when tested in 2011.

Optional BMW X4 safety equipment available includes the Head-up Display, High-beam Assistant, City Braking and Lane Departure Warning systems detailed in the Equipment section of this review.

There’s also ‘e-Call’ (comes as standard on all models), an automated call to the emergency services triggered if the airbags are deployed. It sends details including the car’s location via a BMW Call Centre. It can also be triggered manually be the driver if necessary.

Boot volume is average in the X4. With the rear seats up there’s 500 litres of space (50 less than the X3) and 1,400 with the seats down (200 less than X3). Helpfully, an electric tailgate is standard across the range although the boot’s load lip is quite high, which may make loading heavy items more tricky. The plunging roofline precludes carrying very tall items, too.

As for whether or not BMW X4 practicality for rear passengers has been affected by that chopped roof, average-height adults have plenty of space but taller people may find headroom a little tight. Otherwise space in the back is pretty generous in terms of shoulder and leg room if you’re travelling two-up; a third rear passenger may feel a bit squeezed.

There’s plenty of stowage space within the interior, including generously sized door bins and cup holders.
