Mercedes-Benz GLS-Class vs Land Rover Defender

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.

This feels wrong to say this, but it’s so refreshing not to be driving an electric vehicle. There I said it.

After testing so many EVs lately reviewing a car that has an actual engine is a nice change. And this car definitely has an internal combustion engine - it's the Land Rover Defender Octa Black with a twin-turbo petrol V8.

The Defender Octa is the ultimate form of the 110 Defender. It’s wilder looking, more powerful and more capable, while the Black edition adds darkened elements inside and out for even more visual appeal.

While the Defender Octa Black is special, it’s not alone in a world of high-performance luxury SUVs and its head-to-head rival would be Mercedes-AMG’s G63.

I had the Defender Octa Black for a week and while I didn’t take this beast off-road where it is superbly capable, I put it to the test on some challenging tarmac as well as some challenging real-world family duties.
