Denza B8 vs Mercedes-Benz GLC-Class

What's the difference?

There’s a new name in the luxury upper-large SUV segment and it’s one many buyers will be unfamiliar with. Enter the Denza B8, a brand positioned to BYD much like Genesis is to Hyundai, or Lexus to Toyota.

The flagship B8 6S leans heavily into luxury, space and rugged, squared-off styling, but the big question is whether it does enough to stand out against established heavy hitters like the Toyota LandCruiser 300 Series, Land Rover Defender and Audi Q7.

And then there’s the bigger question - do we actually need an XL SUV with a plug-in hybrid powertrain? More to the point, who exactly is this pitched at?

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?
