2026 Mercedes-Benz Gls450 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.

2026 Subaru Outback Summary

The Subaru Outback holds a special place in the hearts of adventurers everywhere. It’s long been regarded by its fans as a genuine mix of decent on-road manners, family-friendly practicality and sound off-road capability. Just right for light-duty off-roading.

Now, Subaru claims, it has made the Outback even better and a new off-road-focussed variant called the all-wheel-drive Wilderness now sits near the top of the line-up.

The Wilderness is equipped with a 2.4-litre turbo-petrol, four-cylinder, horizontally-opposed 'boxer' engine, 240mm of ground clearance, improved approach/departure angles and electronically controlled dampers.

But is this new Outback all it’s cracked up to be? Read on.
