Mercedes-Benz EQ-Class vs Mercedes-Benz GLC-Class

What's the difference?

The Mercedes-Benz EQC has been on sale in Australia for a little while now, and aside from the local launch event we haven’t had a chance to spend any quality time with the brand’s first fully electric SUV. Until now.

The EQC 400, as it’s officially known, is the German luxury maker’s first foray into the full-EV landscape, and could arguably be seen as the first true luxury electric SUV on sale in Australia. I mean, yeah, there’s the Jaguar i-Pace, but it has a more premium-sporting intent than the EQC, and the Tesla Model X isn’t aimed at a luxury customer, more so a technologically-minded buyer.

So what’s the Merc EQC like to actually live with? We drove it for a week to find out.

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?
