Lexus NX250 vs Mercedes-Benz GLC-Class

What's the difference?

As far as clichés go, attempting to make “a silk purse from a sow’s ear” couldn’t be more apt than when contemplating the original NX of 2014.

What was essentially the Lexus-fication of the vocal, fidgety and thirsty old Toyota RAV4 may have worked a treat sales-wise, but proved trickier when assessed against the lens of a BMW X3, Audi Q5 and Volvo XC60 rival.

The earliest NX just wasn’t refined enough.

This was especially true following the reborn RAV4 arrival in 2019, proving to be embarrassingly more competent – even compared to most luxury midsized SUV alternatives.

Now, finally, the NX redesign has followed suit, moving on to a variation of the Toyota’s stronger, quieter and more advanced TNGA architecture (dubbed GA-K) as a starting base.

Speaking of which, let’s dive straight into the least-expensive version, the NX 250 Luxury 2WD auto, to find out if the most popular Lexus model in Australia has finally found its mojo.

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?
