BMW X3 vs Mercedes-AMG GLC63

What's the difference?

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.

It doesn't feel like that long ago I spent a day with the brand spanking new Mercedes-AMG GLC 63 S when it first arrived in Australia. It's a car that stuck with me, the SpaceX-worthy thrust of AMG's 4.0-litre twin-turbo V8 translating into that dirty V8 exhaust note.

Turns out it wasn't that long ago, but time waits for no car - the 2020 GLC 63 S has arrived, with some useful upgrades and a deep suspicion that someone, somewhere thought the car needed some changes.

And they may be right, because in June 2018, the GLC 63 S assumed an empty throne. Now in 2020, it has the Jaguar F-Pace SVR and BMW X3 and X4 M twins to deal with.

So, under a scorching hot Bathurst sun, I examined the box-fresh GLC 63 S for signs of nefarious activity, hoping things have not changed for the worse just because there are a couple of challengers in town.
