Mercedes-Benz S-Class vs Audi RS3

What's the difference?

It's only in the running for the title of world's best luxury car. No biggie here, then.

Like Rolex and Concorde, S-Class has become a byword for ultimate, and deserved or not, the Mercedes-Benz defines its segment despite the best efforts of the BMW 7 Series, Audi A8, Lexus LS and (sadly now-defunct) Jaguar XJ, as well as pointing the way forward with new technologies that eventually trickle down to more proletarian models.

Replacing the half-million selling W222 unveiled in 2013, the W223 is the latest in a long line since the first W187 Ponton debuted in 1951, and includes the famous ‘Finnies' and Stroke-8 models that followed immediately afterwards, but it is the 1972 W116 that really set the template.

Now, seven generations in, the 2021 S-Class is all-new again, with progressive safety and interior features that should help keep it Australia's bestselling full-sized upper-luxury sedan.

Five-cylinder fury is still kicking!

Audi has just launched the mid-life updated version of its RS3 hatch and sedan in Australia.

With new looks inside and out, the German carmaker has also made a number of subtle tweaks under the skin via software updates. Thankfully, however, the five-cylinder beast lurking under the bonnet remains untouched.

As the viability of pure internal combustion engines in the hot hatch segment dwindles in the age of ever-tightening emissions regulations, will this be the last hurrah for the five-banger RS3?

Read along to see how this latest version stacks up.
