2021 Mercedes-Benz C63 Summary

If you know the Mercedes-AMG C 63 S, you know it’s a hardcore V8 thumper with little in the way of bashfulness. It’s a brawler. A beast.

Now there’s an even more eye-catching AMG C 63 S Coupe, which we’re testing here. It’s the Aero Edition - a collector’s version of the current-generation C 63 S Coupe with a bit more visual bling that also helps it stick to the road better.

It is a local area special edition, with only 63 examples to be sold across Australia and New Zealand. And if the rumours are true, the next-generation will see the V8 engine in danger of being axed in favour of a hybrid, high-performance four-cylinder version. Say it ain’t so!

Well, if the CarsGuide crystal ball turns out to be right, maybe one of these C 63 S Aero Editions is worth getting in your garage quick-smart. Or is it? Let’s go through the criteria and see how it stacks up.

2026 Tesla Model 3 Summary

It’s been in Australia since 2019 and despite the arrival of a comprehensively upgraded version in late 2023, the Tesla Model 3’s once gargantuan popularity has been declining in recent years.

A seemingly never-ending influx of pure-electric alternatives, primarily from China, has eroded the mid-size sedan’s positioning as the go-to, best-value EV choice.

But to its credit Tesla has again evolved the Model 3 proposition with the introduction of this Long Range Rear-Wheel Drive grade in October last year, at the time positioning it as “the longest-range EV in Australia”.

Since then, Tesla has adjusted the model grade name to Premium Long Range Rear-Wheel Drive.

Some additional tweaks, made in response to customer feedback, also illustrates the EV pioneer’s determination to step up in the face of increasingly fierce competition.

So, does this latest Model 3 do enough to earn a spot on your electric vehicle shopping list? We spent a week behind the wheel to find out.

Verdict

The Mercedes-AMG C 63 S Aero Edition is an absolute beast of a car, but it comes at a pretty hefty price. Yes you get a lot of performance, and the fact there are only 63 examples being made for Australia and New Zealand could be enough to get you to sign on the line. For me, though, if I was after a C 63, it’d have to be a wagon. It doesn’t need an Aero pack to look better.

Verdict

Tesla has done enough with the introduction of this Premium Long Range RWD variant to keep the Model 3’s head well and truly above water in an increasingly competitive segment. After more than six years it still looks good, with a pleasant cabin environment, plenty of performance and leading energy efficiency. Safety is top-shelf and it stands up well in terms of practicality and driving dynamics.

That said, the ownership proposition is average, the determination to make so many functions screen-based is frustrating and the optional Full Self-Driving system is unconvincing. With the Model S and Model Y now discontinued globally it will be interesting to see how the Model 3 continues to evolve.
