Mercedes-Benz CLA45 vs BMW X3

What's the difference?

Mercedes-AMG left tongues wagging when it unleashed the original 45 series onto the automotive world seven years ago. It took many forms, including the pioneering A 45 hatch and the unconventional GLA 45 SUV.

That said, we’re here to talk about the third member of that family, the CLA 45 sedan (or coupe if Mercedes-AMG is paying your wage). And no, we don’t mean the old model.

Indeed, the second-generation CLA 45 is here, and it’s packing the most potent series-production four-cylinder engine to date – a title Mercedes-AMG has, of course, held before.

So, is the new CLA 45 a big-step up over its standard-setting predecessor? While it certainly helps that it is now only available in hard-hitting S form in Australia, the only way to really find out is to put it to test. Let’s go!

BMW has recently launched its fourth-generation (G45) X3 range, which comprises three petrol variants including the entry-level 20 xDrive, mid-grade 30e xDrive PHEV and top-shelf M50 xDrive.

The new trio brings revised powertrains, new exterior and interior styling, increased standard equipment, enhanced technology and an emphasis on the use of sustainable materials.

We recently trialled the five-seater flagship to see if it has the right mix of performance and practicality to maintain the X3’s enduring appeal for Aussie families.
