Mercedes-Benz S-Class vs Lexus LM

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.

Most people that are wealthy enough to be ferried around in a car or limo choose a long luxurious sedan like a Mercedes-Benz S-Class, BMW 7 Series or a Lexus LS. Of course, there are now also SUVs that are used for the same purpose.

But what about a plush people mover? There are very few of these available in Australia and they don’t sell in huge numbers. But Lexus believes there is a market for such a model and it has just launched the big and bold LM. The hybrid-only range is a unique proposition and the LM should hold appeal for limo and tourism operators, and larger cashed-up families. 

This initial launch drive was a slightly different format to usual. Given the intended use of the lounge-like model, Lexus arranged for us to be collected in the LM by a chauffeur and ferried from Melbourne to the Mornington Peninsula. From there we got behind the wheel for a brief drive, but many of my impressions will focus on the passenger cabin experience.

Note too that the LM500h does not land until early 2024, so we only sampled the LM350h AWD.

So jump aboard and let’s see if this Lexus can do everything the LS can do - and maybe even a little bit more.
