BMW 4 Series vs BMW X4

What's the difference?

Without a whole lot of fanfare BMW has slipped yet another model into its Australian line-up.

Sitting alongside existing coupe and convertible variants, the new 4 Series Gran Coupe follows the template established by the previous gen version. 

A sports luxury four-door with a sleek, fastback twist, it provides a more adventurous alternative to its close 3 Series cousin. 

Offered in three grades, this is the M440i xDrive, the 3.0-litre, six-cylinder, all-wheel drive 4 Series Gran Coupe flagship. 

It competes with premium all-wheel drive four-doors like Audi’s S5 Sportback, the Jaguar XF P300 R-Dynamic HSE, and the Mercedes-AMG C 43.  

Look, personally I found it amusingly weird when German car companies started sloping the roofs on sedans and calling them “coupes”, despite the fact that they had four doors. Their ability to imagine segments, and find buyers in them, that have no reason to exist is almost something to admire.

But turning SUVs, like the already very capable X3, into coupes? Frankly, it’s like turning an ass into an elbow. Lower the roof to reduce headroom and shrink the boot? Why? Because it will look so sexy people won’t be able to resist it. That’s BMW’s approach with the X4 and, somehow, it seems to work.

And, to be fair, sporty SUVs are not a BMW thing: the Range Rover Evoque, Audi Q5 Sportback, and Mercedes-AMG’s range of GLC Coupé models have all taken off, each contributing toward an unlikely trend that doesn’t seem to be going away any time soon.
