BMW XM vs Mercedes-Benz Eqs450

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?

The EV revolution is bringing plenty of firsts, and this big electric behemoth is yet another one. Meet the EQS450, which Mercedes describes as its first "electric luxury full-size SUV with seven seats".

That is a bit of a mouthful though, right? So let’s shortcut that a bit, shall we? 

What you really need to know is that this is one of the few proper seven-seat electric SUVs on sale in Australia, so it will — a little surprisingly — end up being compared with the increasingly premium Kia and its EV9 when it launches in November.

So what does this electric answer to a high-riding S-Class bring to the table? Well, lots of luxury, of course.
