2023 Mercedes-Benz A-Class Summary

Think of a Mercedes-AMG and the first words that spring to mind are probably not - understated, efficient and restrained. And yet those are probably the best words to describe the all-new C 43.

Of course, before we go any further it’s important to note that the C 43, even in its previous six-cylinder guise, was never meant to be as wild, raucous or powerful as the C63 flagship - that’s simply not its role in the AMG line-up.

But even so, this new model is a dive into fresh territory for the brand and puts a very different spin on the AMG sports sedan as we know it.

This is a four-cylinder model, complete with a Formula One-derived electric turbocharger, so it lacks the sound and fury you expect from something carrying the ‘AMG’ badge - but that doesn’t mean it’s a bad car, as we’ll explain.

2020 MG 3 Summary

This story has been updated in February 2022 to reflect market changes and pricing adjustments for the MG3. It was originally published in the first half of 2020.

My time at CarsGuide started in October 2017, and since then I’ve booked literally thousands of cars across Australia. One car that has eluded me - and the CarsGuide team - over that period is the one you see here: the MG3. Or the MG MG3, or MG 3, if you wish.

Despite asking MG’s Australian arm countless times to loan an MG3 hatchback over that period, the company in charge of the brand’s PR in Australia refused to agree to loan us a vehicle to test. Now the company has an in-house PR team with a pretty decent fleet of press cars, yet still, no MG3.

Over the years, our desire to review the MG3 hatch - and to help you decide whether it's right for you or not - has only gotten stronger because sales have skyrocketed. Back in late 2017 the brand was averaging only a handful of cars per month - indeed, just 52 examples of the MG3 were sold in total in 2017.

Since then, the MG3 has skyrocketed, and it is the best-selling light car in Australia. In 2021, the brand moved more than 13,000 MG3s - meaning it is averaging 250 cars sold per week. Makes the paltry 2017 numbers look a bit meagre. In becoming the number-one seller in the segment, it has beaten big-name rivals including the Kia Rio, Mazda 2 and now defunct Honda Jazz, while also being well clear of the cheaper Kia Picanto, which is what many people will be shopping this car against if price is a key driver for their decision.

And that's the case in point, really - a lot of its success comes down to the price of the Chinese-built, British-badged city car. It’s cheap - but is it a cheerful experience? We got the chance to find out in 2020, thanks to a friendly MG dealership in NSW - and this review has been updated with the most current pricing, because nothing else has changed.

Verdict

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

Verdict

Aside from its safety shortcomings and underwhelming powertrain, it’s easy to see why the MG3 has become a successful part of the brand’s line-up. If you’re driving around a rural centre like I was, it makes a lot of sense.

Whether you choose the Excite model, which has a bit more visual pizzazz, or the Core model, which is our pick of the range, the MG3 is well priced, has the media tech buyers are after, is a charming looking thing that comes in a range of great colours, and is smartly packaged, too.
