Audi RS Q3 vs Mercedes-AMG GLE53

What's the difference?

Is 10 years long enough for a special birthday celebration? When you're a kid, hitting 'double figures' is a pretty big deal, and Audi's obviously in the mood to make some noise because it has lit the candles on a limited 10th anniversary version of its compact SUV rocket ship, the RS Q3.

Only 555 examples of the 'RS Q3 Sportback edition 10 years' will be produced for worldwide consumption, with Audi Australia capturing a batch of them and sending one our way for a brief blast as the fiery five-cylinder starts filtering into dealerships.

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.
