Mercedes-AMG GLE53 vs Audi RS Q8

What's the difference?

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.

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…
