BMW 320d vs Mercedes-AMG GLE53

What's the difference?

Over 44 years BMW has produced more than 15 million examples of the 3 Series. That's roughly one every minute and a half... for over four decades.

And the latest, seventh-generation version of what the famous German maker defines as the "heart and soul" of its brand has landed in Australia.

The new '3' is longer and wider. It's also claimed to be slicker aerodynamically, up to 55 kilos lighter, more fuel efficient, and faster.

And it'll need every advantage it can muster to take a chunk out of its arch rival, the all-conquering Mercedes-Benz C-Class.

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.
