Porsche Cayenne vs Mercedes-AMG GLE53

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.

You might have some traditional notions of what a 'sports car' is.

Low and light, slick and aerodynamic, purely mechanical and centred around the driver. These notions may have held true for a long time, but in an age where Lamborghini makes a Touareg-based super SUV is there room for those parameters to move?

Especially with consumer sentiment indicating the somewhat oxymoronic idea of a low-slung coupe SUV with an AMG powertrain is more than just a niche.

Mercedes told us the previous generation GLE coupe was a major success, amassing up to 25 per cent of the model line's sales split, and its research indicated  a buyer of this massive SUV was drawn to its "performance, style and technology" and was even "a motorsport fan."

Sounds like this buyer would have once been looking for a 'sports car' and like it or not, performance coupe SUVs are here to stay. But does the new GLE 53 Coupe really make for a compelling experience behind the wheel? We found out at its local launch.
