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.

2026 Suzuki Fronx Summary

If there’s one brand that can lay claim to be the best in the ‘cheap and cheerful’ category, it’s probably Suzuki. Not only have its cars been consistently affordable and basic, but also broadly loved by owners.

Now, with small SUVs becoming more and more prominent, Suzuki is bringing a new sub-$30K hybrid light SUV to the market - the Fronx.

Weird name aside, the Fronx promises a fair bit on paper. But can it deliver on the road? We jumped in for a quick spin at its Australian launch to find out.

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.

Verdict

If you’re considering a small car, particularly if an SUV is the goal, a Suzuki should in most cases be on the shopping list. Back-to-basics motoring is key to the brand’s identity. Its most popular model is a tiny ladder-frame 4X4, for example. Hi Jimny.

The Fronx doesn’t break new ground in any practical sense, but it does come in with a decent price and list of features that should sway plenty of small-car fans in the showroom.

It’s decent to look at, comfortable for the segment, and easy to get used to and drive. The numerical rating on this review betrays just how likeable the car is.

It’s not extremely refined and it starts to lose its dynamic shine on rough roads, but in an urban setting the Fronx should excel.
