Porsche Cayenne vs Lexus LS500H

What's the difference?

The Porsche Cayenne Turbo GT needs a better name. This is the king of Cayennes and quite possibly the ruler of all super SUVs.

Well, the Cayenne Turbo GT is the fastest SUV around the Nurburgring Nordschleife. Not just that, it has such colossal power and torque it'll be side-by-side with a Porsche 911 GT3 RS in a sprint from 0-100km/h. No, a better name for this SUV would be the Cayenne GT3.

Which is perfect for me because I'm at the point in my life where although I love full-on and noisy cars I also have a full-on and noisy family.

We lived with the Cayenne Turbo GT for a week to find out if this super SUV was also a super family car - from practicality to safety.

We're also a family with ridiculously high expectations of luxury SUVs having lived with and tested each of the Cayenne Turbo GT's rivals - from the Lamborghini Urus and Bentley Bentayga to the Aston Martin DBX and Alfa Romeo Stelvio Quadrifoglio.

Almost 30 years after Lexus launched its original LS flagship sedan, the fifth generation of the car has arrived in Australia in what appears to be the brand’s never-ending battle to hunt down and beat Mercedes-Benz, BMW and Audi at their own game.

In some markets it looks as though Lexus is making headway. In the United States last year Mercedes-Benz was the best-selling luxury brand, followed by BMW and then Lexus. To give you even more insight, 50 per cent of all Lexus sales globally are in the US.

The story is different in Australia, with Lexus hardly a threat to the big three Germans, selling about a third less each month.

The Lexus LS is the Japanese prestige brand’s flagship and comes with a price that nudges up against formidable rivals. There’s the Mercedes-Benz S-Class, BMW 7 Series and Audi’s A8. Only the best cars from a few of the best brands in the world – no pressure, Lexus.

This may even be a reason to buy one – in that it’s not one of the traditional three. You could see Lexus as the popular underdog that in some ways does a better job than the usual suspects. A people’s favourite perhaps?

Just look at how often it’s mentioned in songs. According to lyrics.com.au the word Lexus has been used in 873 songs. Meanwhile Mercedes Benz appears in 500, Audi in 402 and BMW in 307.

With all this in mind we headed to the Australian launch to drive the LS 500 and its hybrid twin the 500h.
