Summary
The BMW X4 is effectively the X3 SUV in a less boxy shape – most obviously a strongly raked rear end with a liftback tailgate, plus more sporty touches such as bespoke lights.
Of course, such a shape means less interior room. So while the X4 has five doors and a tailgate like the X3, reviewers point out the tighter rear-seat space – even in the latest Mk2 version, which launched in 2018 and is very slightly longer than its predecessor.
Highlighted are the tighter headroom, a feeling of being more ‘hunkered down’ in the car and far less visibility through the rear screen.
The interior, effectively the same as the X3’s, comes in for much praise. Testers like its quality of technology, the materials and how they are fitted. However some describe the mix of finishes as over-fussy.
Reviews of the BMW X4 reserve most praise for its on-the-road performance, described as both comfortable and with excellent handling, though some describe the ride as a little firm.
As of January 2024, the BMW X4 holds a New Car Expert Rating of D, with a score of 58%. Although it has an excellent reliability score, it loses out with poor running costs and only middling review scores from the media. Its safety rating from Euro NCAP has also expired due to age.

“It may not quite match rivals for rear-seat space, but the X4 does deliver a surprisingly dynamic drive – one which you wouldn’t quite expect from a car in this segment.”

“The BMW X4 offers a little extra style over its X3 sibling, but it’s more expensive and sacrifices practicality.” (Jordan Katsianis)

“The BMW X4 is an impressive all-rounder with an endearingly sporting touch. It offers responsive car-like dynamics, impressive mechanical refinement, class-competitive quality and a good deal of space, if not the versatility and everyday ease of use delivered by the more upright X3.”

“The BMW X4 is undoubtedly an engaging car to drive and own but whether you should be considering one will probably hinge on how you perceive its appearance. If you’re a fan, then its extra costs and smaller boot are probably a price worth paying.”

“Although it may not be the best-looking SUV around, the BMW X4 certainly has its merits and offers customers another option in a different niche. The driving setup is surprisingly both sporty and comfortable. Just be careful not to add too many expensive options to it.”

“You can’t get away from the fact that the BMW X4 is less practical than its boxy brother, the X3, with which it shares much of its parts and engineering. The semi-coupe styling means less luggage room and the lower ground clearance limits its off-road ability. But so what?”

“Larger, lighter and more powerful, the 2018 BMW X4 is wider and longer than the outgoing model, but weighs 50kg less thanks to the extensive use of aluminium and ultra-high-strength grades of steel.”

“Once you get over the monstrous appearance (some may like it), the BMW X4 is essentially a slightly sportier X3. That means it gets an upmarket interior, although BMW is persevering with button overload and a variety of clashing materials competing for the driver’s attention.”

Notes on safety rating
The BMW X4 was originally assessed by Euro NCAP back in 2017 and awarded a five-star rating. However, this rating expired in January 2020 and is no longer valid as the car no longer meets the standards required for such a rating. This is normal practice, as Euro NCAP reviews its ratings on most cars annually with most ratings expiring after about six or seven years.
However, if you are comparing a used X4 to vehicles of similar age, whose ratings will have probably also expired, its safety rating score is still useful.
The BMW X4 shares its (now expired) safety rating with the almost-identical X3. Rather than physically crashing several X4s, Euro NCAP would have required BMW to submit specific data to show that the changes made to the X4’s roofline would not affect how it performs in an accident.

Reliability score
All data based on MotorEasy average workshop costs for extended car warranty claims
The BMW X4 has an excellent reliability score of 80%, according to workshop and warranty data provided exclusively to The Car Expert by our partner, MotorEasy. This score applies to the current (2018 onwards) X4 as well as to older models.
The biggest concern for X4 owners is the engine. Although there have been very few warranty claims, the average repair bill is nearly £3,000. Other repairs, for suspension, electrics and braking, have been very cheap.
If you own a BMW X4 or are interested in buying a used X4, you’d do well to make sure that any used car warranty you buy has adequate cover for engine failures and faults.
