2020 Mercedes-AMG GLC63 Summary

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.

2025 Tesla Model Y Summary

I don’t think I’m overselling it to say that this is the car that could make or break Tesla in Australia and around the world. 

Crazy, right? That seemed impossible not so long ago, back when the brand appeared untouchable. But new competition, largely from China, plus the giant Musk-shaped elefant (it is German for elephant…) in the room, has seen sales and profit plummet.

Just last month, for example, the Tesla Model Y lost its best-seller crown in Australia to BYD, admittedly in the weeks before the new 'Juniper' version arrived.

The point is, a new version of its biggest seller is a Very Big Deal. But have they changed enough, and changed it well enough, to cut through the noise?

We put the cheapest variant, the Tesla Model Y RWD, to the test to find out.
