2024 Mazda 3 Summary

Half a decade on, the current-generation Mazda 3 has weathered a world of change.

Cheap cars have vanished. Electric vehicles are commonplace and the small car class it belongs to has been decimated by SUVs. Big names like the Ford Focus, Holden Astra and Mitsubishi Lancer are history.

But while it looks identical to the car unveiled at the 2018 LA Auto Show, today’s Mazda 3 has also evolved, albeit gently.

Let’s see how competitive the latest and improved (as well as more expensive) version is.

2020 Mercedes-Benz A45 Summary

Driving the first-generation Mercedes-AMG A 45 in 2013 was an intense, noisy, brutal experience and I loved every bone-shaking, ear-bleeding moment of it.

But I’m older now, married and have children, and while this is also an intense, noisy, brutal experience I now prefer cars to be less like a 24-hour, seven-day-a-week continuous cage fight. So, I was surprised to find the new-generation A45 S has grown up a bit, too.

So, like me, is the new Mercedes-AMG A 45 S 4Matic+ not as quick as it used to be, and does it have a dad bod, now, too? Far from it. If anything, it’s matured into the serious weapon of a hot hatch it was always supposed to be.

Verdict

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

Verdict

The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.
