2021 Mazda CX-9 Summary

The second-generation Mazda CX-9 may have been on sale in Australia for nearly five years now, but it remains the second best-selling large SUV using unibody construction (as opposed to old-school, off-road-focused body-on-frame).

That said, it is getting on a bit, so Mazda’s given it an update with a twist for 2021, hoping to inject a little bit more life into its flagship model.

And when we say twist, we mean it. After all, who would’ve thought there’d ever be a six-seat CX-9? Well, we’ve checked it out to see if it’s the version we needed all along. Read on.

2025 Mercedes-Benz GLC-Class Summary

Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.

Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.

While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

But how does the new powertrain suit the GLC63 - is it just technically better or is it holistically improved?

Verdict

The CX-9 is still a great option for families looking for a large SUV, even if it is starting to show its age as new rivals continue to launch with newer technologies.

That said, the availability of a luxury-focused six-seat configuration (Azami LE AWD) for the first time might be enough to convince some buyers to give it further consideration.

But for others who need the versatility of seven seats, this is still the CX-9 we’ve all come to know and love – but just a little bit better – particularly in its best-selling Azami AWD form.

Verdict

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.
