2026 Lexus RX Summary

Lexus has finally brought a plug-in hybrid to the Australian market with the RX450h+, and we’ve been testing the second-from-the-top Sports Luxury grade to see how it stacks up.

Promising a blend of electric efficiency and the high-end comfort Lexus is known for, this large SUV steps into a competitive segment. But does it deliver on both fronts?

2025 Rolls-Royce Cullinan Summary

The truly great thing about great wealth - I mean like, drop $1 million on a new Rolls-Royce with a casual yawn and a mouse click wealth - would be how great it is not having to do anything for yourself.

Personally, I would hire a chef, so I’d never have to cook again, and a pilot to fly my private jet, so I’d never have to catch pneumonia while flying 34 hours to Ibiza with strangers to do my weird job (oh, and if I was rich I wouldn’t have to work anyway), and in theory I might even hire a chauffeur for those odd times when I didn’t want to drive myself in one of my fleet of beautiful cars.

All right, so I can’t even imagine that last one, but the most interesting fact I gleaned while in Spain, tirelessly testing the new Rolls-Royce Cullinan Series II, is that even the ridiculously rich are falling out of love with not driving these days.

Perhaps, being tech-savvy types, they can see the end of driving and the rise of autonomy coming and they want to make the most of it while they still can. But according to Rolls, the percentage of its buyers who sit in the back rather than in the driver’s seat has flipped entirely over the past 15 years.

Back in the day, 80 per cent of Rolls owners were back-seat passengers, blowing cigar smoke at the back of a chauffeur’s head, while 20 per cent actually drove their expensive motors.

Today, the number who drive themselves has soared to 80 per cent, and apparently that’s not just because it would feel weird being chauffeured around in what is now the most popular Rolls-Royce by far - the Cullinan SUV.

The other big change, apparently, is that the average age of a Rolls-Royce buyer has also dropped, from 56 to the low 40s. And that means more buyers with kids, and gold-plated prams and other associated dross, which means they need bigger Rolls-Royces, family-sized SUV ones, which again helps to explain why the Cullinan now makes up as much as half of all the brand’s sales in some markets.

And why the arrival of this, the facelifted, tweaked and twirled Series II version of a car that was greeted cynically by many in the media when it arrived (“one group was not sceptical, and that was our clients,” as a Rolls spokeswoman delightedly pointed out) is such a big deal.

2026 Lexus RX 2025 Rolls-Royce Cullinan

Verdict

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

Verdict

The Cullinan might not be the most beautiful or traditional Rolls-Royce, and it’s a shame modern success means providing an SUV option to everyone, but it’s still a remarkable machine, either to drive or just to sit in. It remains not just a marvel of engineering, but a marvellous of engineering. Hats doffed, old bean.
