2026 Denza B8 Summary

There’s a new name in the luxury upper-large SUV segment and it’s one many buyers will be unfamiliar with. Enter the Denza B8, a brand positioned to BYD much like Genesis is to Hyundai, or Lexus to Toyota.

The flagship B8 6S leans heavily into luxury, space and rugged, squared-off styling, but the big question is whether it does enough to stand out against established heavy hitters like the Toyota LandCruiser 300 Series, Land Rover Defender and Audi Q7.

And then there’s the bigger question - do we actually need an XL SUV with a plug-in hybrid powertrain? More to the point, who exactly is this pitched at?

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.
