Mercedes-AMG GLC63 vs BMW X5

What's the difference?

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.

The BMW X5 is a leading contender in the ‘Over $70K Large SUV’ division of Australia’s new car market, which is a hotly-contested segment boasting 15 marques and 25 models.

The X5 has hit an enduring sweet spot with Aussie buyers in terms of size, performance and price. BMW prefers to call it a Sports Activity Vehicle (SAV) as distinct from its Sports Utility Vehicle (SUV) rivals.

Clearly, any word association with a utility is something BMW Group Australia wants to avoid after recently launching its latest X5 range, which brings numerous enhancements including design revisions, increased standard equipment, refreshed powertrains and more.

We were entrusted with the digital ‘Comfort Access’ key to one of the latest X5s, to understand from a family car perspective why this model range enjoys such enduring popularity with prestige SUV (sorry, SAV) buyers.
