2026 Lexus LX Summary

The march away from diesel power and towards a petrol-hybrid future in off-roaders continues. Okay, so it’s a full-sized Lexus we’re talking about, but the off-road credentials of the Toyota LandCruiser 300 Series-based Lexus LX have never been in question, have they?

The full-sized, super-lux Lexus LX might never see the Simpson Desert or the Old Telegraph Track, but that doesn’t mean it couldn’t tackle either with a fair degree of ease. So there’s no way Lexus would allow a new hybrid driveline to compromise any of that. Besides, this is the same driveline that will take the LandCruiser on its next step, so you better believe it’s the real deal.

Of course, the Lexus badge and somewhat frightening price tag also infer a high degree of plush and tech, and, let’s be honest, those elements are more likely to get a leading role in the LX’s day-to-day strut, as opposed to the walk-on part played by the off-road stuff.

So does all this make the LX one huge, high-tech mash up of conflicting priorities, then? That probably depends on how pragmatically you view motor vehicles generally, but one thing’s for sure, if the hybrid LX is paving the way for the next generation of LandCruiser powerplants and drivelines, then we’re all ears.

2026 Audi RS Q8 Summary

Not to spoil the illusion, but at their core the Lamborghini Urus, Bentley Bentayga and Porsche Cayenne all share the same base mechanical DNA. And yet despite their huge price tags and enviable reputation for performance, the fastest SUV isn’t one of them - it’s an Audi.

The new Audi RS Q8 Performance, to be precise, which has lapped the famous Nurburgring in Germany in record time, usurping the Cayenne Turbo GT in the process.

Boasting the most powerful internal combustion engine Audi has ever installed in a production car, ceramic brakes and a highly advanced suspension package, the RS Q8 Performance takes the German brand’s SUVs to a new level of, how do I put this… performance.

So it’s an appropriate name, but is it an appropriate car for Australian buyers looking for something fast, spacious and special? Read on to find out…

Verdict

Huge specification in terms of convenience and safety gear are matched by an equally huge range of abilities in this vehicle. As well as rock hopping with the best of them, this is also a phenomenal touring rig and a more-than-capable off-roader. Of course, whether you can see yourself clambering up the side of a muddy creek crossing in $202,000 worth of vehicle is a personal matter, but rest assured, the Lexus will do it if you ask it to.

In the case of the hybrid LX, however, the vehicle now has an extra dimension to cover off, and from what we can see, it does take the efficiency and running costs of the big wagon to a new, better place. Mind you, that may only be the case if diesel continues to cost a dollar-a-litre more than petrol at the bowser.

The shift to petrol power also brings with it a level of mechanical background noise that we’re not entirely sure fits the Lexus legend, while additions such as the camera-based rear-view mirror system seems to be a conversation starter rather than an actual improvement.

Verdict

The Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.
