Audi RS7 vs Mercedes-AMG GLC63

What's the difference?

If you’re looking for a sedan version of the RS 6 Avant, then you’ve come to the right place – sort of. See there is no RS 6 Sedan, but the RS 7 Sportback is the next best thing – you may even find it an even better thing because not only does it share RS 6 Avant’s outrageous engine and high-performance hardware, it’s also a sedan …but with a hatchback.

And if that kind of thing makes you happy, sit down – because the new generation RS 7 Sportback has just landed.

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.
