Mercedes-Benz GLS vs BMW XM

What's the difference?

It’s fair to say Mercedes-AMG GLS63 buyers really want it all; good looks, cutting-edge technology, seven-seat practicality, leading safety and V8 performance to name a few key desirables. And, lucky for them, the new model is finally here.

Yep, the latest GLS63 is yet another exercise in excess, leaving very little to be desired by its buyers. Indeed, it ticks almost every box when it comes to a utility vehicle that well and truly puts the sports in Sports Utility Vehicle.

But, of course, this raises questions over whether or not the GLS63 is trying to do too much. And given this model does a whole lot more than its predecessor, these questions need to be answered again. Read on.

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?
