2026 Lexus UX Summary

Replacing the long-standing UX250h, the more powerful Lexus UX300h hybrid sits at the luxury end of the compact SUV segment, and the latest update brings a refined line-up along with tweaks to both design and technology. In this review, I’m looking at the base Luxury grade to see what it's like to live with this hybrid day-today and how it stacks up against its nearest rivals.

2026 Mercedes-Benz GLS-Class Summary

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.

Verdict

The updated Lexus UX300h Luxury is a solid entry in the premium compact SUV segment. It doesn’t break new ground, and there are areas that could be improved, but it handles well, offers a thoughtful selection of amenities for a base-grade luxury model, and its compact size makes it easy to park almost anywhere. For buyers seeking a stylish, efficient, and practical hybrid with a luxury badge, it’s a dependable choice.

Verdict

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.
