BYD Seal vs Mercedes-Benz GLC-Class

What's the difference?

BYD. The three letters which keep auto executives from the world's top brands up at night.

The brand’s meteoric rise in Australia from a trickle of imports to a torrent of Chinese-built EVs, outselling even Tesla in the first month of 2024, is testament to this relative newcomer’s ability to surprise and impress its buyers and the industry as a whole.

The car we’re looking at for this review, the Seal, could be its biggest challenge yet. Not only does it have to compete head-to-head with the car which put EVs on the map for mainstream buyers - the Tesla Model 3 - but it also has to vie for a share of the increasingly shrinking sedan market.

So, what’s the deal with the Seal? Is it any good? And, why did BYD choose to name it after a marine mammal? Read on to find out.

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?
