Mercedes-Benz GLC-Class vs Audi Q6 E-Tron

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?

From a few paces back, the Q6 e-tron is easy to mistake for just another Audi.

After all, Audi, perhaps above all its contemporaries, has established such a consistent look and feel for its entire range.

But this is no regular Audi. The brand tells us the Q6 e-tron is the most significant new vehicle it has launched in a decade.

Underneath its familiar visage, Audi is so excited about the Q6 e-tron because it brings with it a ground-up new-vehicle platform, which brings with it some forward leaps when it comes to technology.

But does being new actually make the Q6 e-tron a good car? We went to its Australian media launch to find out.
