BMW 125i vs BMW X4

What's the difference?

If you think it’s a Mercedes-Benz A-Class you want or maybe an Audi A3 Sportback or even a Volkswagen Golf, then stop and read this first before making a purchase.

The BMW 1 Series alternative isn’t just another prestige little car, because there are some fundamental differences between this 1 and those others, and they could cause you to totally rethink your decision.

If you’re already keen on getting a 1 Series then you need to read this, too, not only to help you find the right one, but also to alert you to what might be a couple of uncomfortable truths.

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.
