BMW IX3 vs Mercedes-Benz GLC-Class

What's the difference?

There are a lot of big numbers surrounding the BMW iX3, the German brand’s new-from-the-ground-up EV that acts as the flagbearer for its future-facing Neue Klasse (or New Class) architecture, designed to distil all the ingredients that make a BMW a BMW, and then electrify for them for the post-ICE (internal combustion engine) era.

But the one that really stood out? 805. That’s how many kilometres of driving range the iX3 will deliver, though admittedly in its most efficient and least exciting driving modes. That is bonkers, right?

It’s worth pointing out the first BMW i3, which only launched a decade-or-so ago, delivered more like 150km on what would have been the WLTP cycle, if it had existed then. Talk about leaps and bounds.

A good start for the newest BMW EV, then. But what else does the iX3 have to offer?

Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.

Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.

While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

But how does the new powertrain suit the GLC63 - is it just technically better or is it holistically improved?
