The BMW X3 family has undergone a bit of a coming of age in transition to its third full-model generation, something about which you’ll be reading in detail in this review.

And that growing up and general maturing process coincides neatly with a dimensional expansion that has made it a longer, wider car than the original BMW X5 that arrived on the scene in 1999.

Since the X3’s launch in 2003, BMW has sold more than 1.5 million units worldwide, a success story it will no doubt be eager to continue with the version that’ll take the model into its third decade on sale.

The car’s increase in overall length – 51mm over the outgoing model – creates more space in the back than ever before and aesthetically the X3 looks even more athletic. There’s no drastic departure from the design language of the second-gen model, but the mild redesign helps give the soft-roader a new lease of life and brings it closer in line with BMW’s other models.

The X3’s price position within BMW’s SUV range is as you’d imagine it to be. Starting at £37,980, it’s more than £10,000 cheaper than the no-frills version of the X5 and just over £11,000 more expensive than the school-run-favourite X1 – even though the car is now a much closer match on size for the X5 than the X1. A good omen for metal-for-the-money fans, perhaps.

Those after a slightly fruitier X3 will see the appeal in the M40i – the first X3 to receive the M Performance treatment – thanks to its 355bhp 3.0-litre six-cylinder engine and claimed 0-62mph time of 4.8sec.

The car we’re testing here, however, is the bigger-selling and more sensible 188bhp 2.0-litre four-cylinder diesel, although four-cylinder petrol and six-cylinder diesel engines arealso available.

BMW claims the latest X3’s design is more confident and off-road inspired – and for the most part, as the road test always has, we’ll leave its visual merits up to you to judge.

Where the car is really going to have to impress, though, is on the tarmac. BMW has a knack for making cars a cut above the competition when it comes to driving dynamics, but the X3 hasn’t traditionally been the best of them.

This road test will determine whether this new version better lives up to its maker’s reputation.

  • BMW 6 Series Gran Turismo front
    The new BMW 6 Series Gran Turismo
    First Drive
    16 February 2018
    The top-of-the-line 6 Series Gran Turismo has arrived in the UK, but does a more potent engine increase its unusual appeal?
  • Audi TT RS Coupé
    First Drive
    16 February 2018
    The Audi TT RS has the looks, a vociferous engine and the supercar-baiting performance, but is it too uncompromising to use as a daily driver?
  • Range Rover Velar front quarter
    The new Range Rover Velar P300 features a four-cylinder petrol engine
    First Drive
    16 February 2018
    JLR’s most powerful four-pot isn’t the engine the Velar truly wants but perhaps the one that makes most sense
  • Mitsubishi Outlander diesel
    The Mitsubishi Outlander diesel is available with five or seven seats
    First Drive
    15 February 2018
    The Outlander isn't just available as a PHEV: how does the diesel version compare to seven-seat rivals such as the Nissan X-Trail and Skoda Kodiaq?
  • Ferrari Portofino
    The Portofino's engine revs to a tremulous 7500rpm; it has a huge swell of mid-range torque; and it responds crisply at all times and feels unusually progressive in its power delivery for a highly stressed turbo
    First Drive
    13 February 2018
    Faster, more agile and perhaps more authentically ‘Ferrari’, but the Portofino lacks the dynamic sophistication of a great GT car, just like its predecessor
