Mercedes-Benz C300 vs BMW 230i

What's the difference?

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.

If one is good, two must be better, right? Or twice as good. The question is whether that simple equation adds up for BMW's upgraded 1 and 2 Series siblings – the former, a range of five-door hatches, the latter, a line-up of cabriolets and coupes, with a major addition in the shape of the full-house, performance-focused M2.

Prices are up, and changes are mostly under the skin, so you're not getting  big visual bang for your extra bucks. But the new and improved 2 has plenty to offer when it comes to added spec and tech.
