Mercedes-Benz S450 vs MG Mg7

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 Australian market hasn’t truly revolved around a sedan since I was a kid. These days it’s all about SUVs, and anything low-slung is easy to overlook when it comes to family hauling. Add to that the current fixation on hybrid and electric powertrains, and a mid-size petrol sedan feels almost out of step.

And yet, here’s the MG7.

It’s a mid-size fastback with a turbo-petrol engine and just one trim level. Its sharp styling is matched by an even sharper price, and it doesn’t seem particularly concerned about not fitting the current mould.

It lines up against the Toyota Camry SL, Skoda Octavia Sportline and Hyundai Sonata N Line and raises an interesting question. Is this the sedan comeback nobody saw coming? And could it remind modern families why sedans were once king?
