Mercedes-Benz GLC-Class vs Audi Q8

What's the difference?

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?

The Audi Q8 has had a mid-life upgrade and it brings a few minor tweaks to the design, technology and equipment.

Plug-in hybrids tend to rank a little lower on my excitement scale when it comes to available powertrains because I usually find the constant charging inconvenient.

However, the electric driving range of the 60 TSFIe quattro S Line grade has been bolstered by 27km, increasing it to 74km overall.
