BMW M3 vs Mercedes-Benz S450

What's the difference?

There’s no point waxing too lyrical here, because the facts surrounding the M3 Touring are more than exciting enough.

It’s a (kind of) family friendly wagon with oodles of space and practicality. It’s also an unhinged performance weapon with a thumping 3.0-litre twin-turbo-petrol inline six-cylinder engine.

And it has been years — decades, even — in the making. So, has it been worth the wait? Let’s strap in and find out.

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.
