2026 Land Rover Defender Summary

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.

2024 Mercedes-Benz SL63 Summary

An SL sports car has been part of the Mercedes-Benz line-up since the early 1950s, and when I think of this model I see that golden years of Hollywood star (with the great hairstyle) Yul Brynner, in the late 1950s cruising the French Riviera in his 300SL roadster. Or Sophia Loren regularly posing with her 300SL Gullwing coupe around the same time.

Over seven iterations and more than seven decades it has stood for performance, glamour and exclusivity. And after a two-year hiatus the Mercedes-AMG SL63 roadster has made a comeback to the Australian market.
