BMW XM vs Mercedes-AMG GLE53

What's the difference?

BMW’s new XM is a tricky customer to pigeon-hole. Yes, it’s a huge, super-lux SUV and, yes, it’s all-wheel drive and features a station-wagon layout.

But it’s also a M-car and that infers super high performance. Weighing in one the wrong side of 2700kg, however, makes that a difficult task for any engineer.

This car also left us wondering if perhaps the glory days of M Division sports cars and coupes might behind it and SUVs like this one represent the road ahead.

But fear not: The CEO of M Division himself, assured us that the XM is a showcase for what an M badge can do, rather than a mission statement for the brand.

So, with that in mind, does this car have the wow factor that places it somewhere between peak oligarch and a motor-show concept car? Does it move the goal posts for big luxury SUVs? Does it even matter that it’s a plug-in hybrid?

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.
