Lexus Lm350H vs Mercedes-Benz Gls450

What's the difference?

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.

The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.

It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.

It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.
