2025 Lexus NX Summary

The Lexus NX 450h+ F Sport is a well-specified and plush-looking medium SUV that has a plug-in hybrid powertrain - a first for the brand.

On paper, it seems to tick the boxes for size, luxury and efficiency but we've been testing the flagship grade to see if it's a winning combo in real life.

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 Lexus NX450h+ F Sport is a gorgeous mid-size SUV that combines great specs and a fairly efficient plug-in hybrid powertrain. It’s a comfortable and easy ride which should appeal to a wide range of driving styles. It also looks good parked at the kerbside of a city street and with it ticking most of the boxes, it may become your new best friend.

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.
