Mercedes-Benz S450 vs Lexus LS

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.

Surprisingly, for people who would rather be driven than drive themselves, there are quite a few options available in the large luxury sedan market.

While on the whole sedans have fallen from favour, this niche corner of the market continues to let the three-box design thrive.

The options here have changed a bit in the last few years, though, so how does the Lexus flagship, the LS fit into the picture? I drove one around for a week to find out.
