Mercedes-AMG GLC63 vs Porsche 911

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 icon is electric. Well, kind of.

This is the new Porsche 911 Carrera GTS, which ushers in a facelift for the brand’s most famous model — and it’s one that introduces a pretty major change.

That faint whistling you hear is most likely the distant wails of the Porsche purists, because this new 911 is now a hybrid.

Yes, the Carrera GTS features Porsche’s clever T-Hybrid engine, which is the brand’s take on electrifying the world’s most famous sports car.

It’s faster than the model it replaces, but it also fundamentally alters the formula that has made the 911 the world’s most iconic sports car.

The question is, does it alter it for the better?
