Audi SQ5 vs Mercedes-AMG GLC63

What's the difference?

The Audi Q5 now has a sportier-looking sibling, with the German brand's all-time best-selling SUV welcoming a sleeker, more aggressive solution it calls its Sportback range.

And look, spoiler alert, it looks better than the regular Q5. It's as simple as that. So if that's all you're here to find out, feel free to close the laptop, put the phone away, and move on with your day.

But you'd be doing yourself a disservice, because there are more questions to be answered here. Like will you paying in on-board comfort for this new raked roofline? Do the Sportback's sporty intentions make for a more annoying daily drive? And how much does Audi want you to pay for one?

All these questions and more answered. So stay with me.

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.
