2024 Porsche Cayenne Summary

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.

2021 Mercedes-Benz GLS-Class Summary

It’s fair to say Mercedes-AMG GLS63 buyers really want it all; good looks, cutting-edge technology, seven-seat practicality, leading safety and V8 performance to name a few key desirables. And, lucky for them, the new model is finally here.

Yep, the latest GLS63 is yet another exercise in excess, leaving very little to be desired by its buyers. Indeed, it ticks almost every box when it comes to a utility vehicle that well and truly puts the sports in Sports Utility Vehicle.

But, of course, this raises questions over whether or not the GLS63 is trying to do too much. And given this model does a whole lot more than its predecessor, these questions need to be answered again. Read on.
