2022 Mercedes-Benz C300 Summary

Australia's relationship status with the Mercedes C-Class has long been… complicated.

Over 40 years and five generations, the German midsized luxury sedan has been a paragon of efficiency and safety on one hand, but on the other, well, the quality and ride comfort haven't lived up to brand expectations.

Now the completely redesigned version has landed in Australia, with shrunken S-Class limousine styling to take on not only the BMW 3 Series, Audi A4 and Genesis G70, but rivals as disparate as the Hyundai Ioniq 5 and Tesla Model 3.

The question is? Is this latest, sixth-generation, new-from-the-ground-up C-Class good enough to take on all those and more? Let's find out.

2025 Smart 3 Summary

Smart is back.

Not with the classic ForTwo two-seater city car, oddball four-seater ForFour hatch or dinky Roadster targa top. Those were yesterday’s cars.

Today, Smart – as a 50/50 joint-venture between Germany’s Mercedes-Benz (the brand’s originator) and China’s Geely – is all about SUVs. Electric SUVs.

The boxy #1 (pronounced “hashtag-one”) is a small SUV and the sleeker #3 is the coupe-esque performance crossover version. Both are made in China and use Geely technologies.

We take a long, hard look at the range-topping #3 Brabus, the speediest, sexiest and exxiest of the lot. Let’s go.
