Mercedes-Benz S450 vs Porsche 911

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.

The icon is electric. Well, kind of.

This is the new Porsche 911 Carrera GTS, which ushers in a facelift for the brand’s most famous model — and it’s one that introduces a pretty major change.

That faint whistling you hear is most likely the distant wails of the Porsche purists, because this new 911 is now a hybrid.

Yes, the Carrera GTS features Porsche’s clever T-Hybrid engine, which is the brand’s take on electrifying the world’s most famous sports car.

It’s faster than the model it replaces, but it also fundamentally alters the formula that has made the 911 the world’s most iconic sports car.

The question is, does it alter it for the better?
