BMW 4 Series vs Mercedes-Benz C300

What's the difference?

Without a whole lot of fanfare BMW has slipped yet another model into its Australian line-up.

Sitting alongside existing coupe and convertible variants, the new 4 Series Gran Coupe follows the template established by the previous gen version. 

A sports luxury four-door with a sleek, fastback twist, it provides a more adventurous alternative to its close 3 Series cousin. 

Offered in three grades, this is the M440i xDrive, the 3.0-litre, six-cylinder, all-wheel drive 4 Series Gran Coupe flagship. 

It competes with premium all-wheel drive four-doors like Audi’s S5 Sportback, the Jaguar XF P300 R-Dynamic HSE, and the Mercedes-AMG C 43.  

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.
