Mercedes-Benz Eqs450 vs BMW XM

What's the difference?

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.

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?
