Mercedes-Benz C350 E vs Mercedes-Benz GLC-Class

What's the difference?

They're doing it again! Actually they've been doing it again for a bit now. It’s Mercedes-Benz Australia and plug-in hybrid tech.

The Ross and Rachel, or Jim and Pam of the premium automotive world.

It's been a will they, won't they for a while, and in the past Mercedes has dipped its proverbial plug into the electrons a few times and gotten cold feet.

But now it says it’s all in. There are others, the GLA and GLC SUVs, plus there’s the new C63 performance car, but this one feels like a bit of an arrival.

Yeah, the C-Class is no longer the Mercedes-Benz in terms of sales, but it might be the best way to make the most of a bit of battery power.

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?
