Mercedes-Benz Gls450 vs GWM Cannon Alpha

What's the difference?

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.

Chinese automotive brand GWM (aka Great Wall Motors) has been making headlines, given that in 2024 it was the first manufacturer to launch an HEV (Hybrid Electric Vehicle) ute in Australia. And in 2025 it's replaced that short-lived model with a PHEV (Plug-in Hybrid Electric Vehicle) version.

The decision to axe the original Alpha Hybrid was a no-brainer for GWM, given its PHEV successor offers not only short-haul pure-electric driving but also superior power, torque and driving range plus the enhanced ride comfort and handling of four-coil suspension.

We were recently handed the keys to the latest iteration of this lavishly-equipped 4x4 dual-cab ute to assess its workhorse credentials from a tradie’s perspective.
