2018 BMW X4 M40i quick performance review

Why? That's the first thing that came to mind when BMW unveiled the X4, an SUV-cum-coupe. Strong sales justify its existence, and now, in its second generation, the X4 gains a hot version. Enter the $109,900 X4 M40i.

Longer, lower and wider than before, the new X4 is more than just a gigantic kidney grille. Sitting behind it, though, is the gem of the M Performance transformation – the 265kW/500Nm B58 inline-six.

With a slick ZF eight-speed ‘box and the twin-scroll turbo six, it’s no wonder the 1825kg M40i reaches 100km/h in 4.8sec. With AWD and the torque vectoring M Differential, you can really drive the nose to the apex on the outside back wheel (30mm wider rear track over X3).

With the slackened ESC setting, exciting the X4’s bum on corner entry is even possible… which seems uncouth for an SUV that can’t totally escape its kerb weight. It sounds brilliant, too.

The interior receives a makeover, upping the opulence and adding a digital instrument cluster. As far as an entree to the X4M main, this coupe-esque SUV leaves us salivating for the next course. It’s unquestionably fast and surprisingly capable – almost even playful.

Maybe the X4 M40i isn’t a question of why, but why not?
