Mercedes-Benz GLC-Class vs BMW X5

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 BMW X5 is a leading contender in the ‘Over $70K Large SUV’ division of Australia’s new car market, which is a hotly-contested segment boasting 15 marques and 25 models.

The X5 has hit an enduring sweet spot with Aussie buyers in terms of size, performance and price. BMW prefers to call it a Sports Activity Vehicle (SAV) as distinct from its Sports Utility Vehicle (SUV) rivals.

Clearly, any word association with a utility is something BMW Group Australia wants to avoid after recently launching its latest X5 range, which brings numerous enhancements including design revisions, increased standard equipment, refreshed powertrains and more.

We were entrusted with the digital ‘Comfort Access’ key to one of the latest X5s, to understand from a family car perspective why this model range enjoys such enduring popularity with prestige SUV (sorry, SAV) buyers.
