2023 Lexus LS Summary

Surprisingly, for people who would rather be driven than drive themselves, there are quite a few options available in the large luxury sedan market.

While on the whole sedans have fallen from favour, this niche corner of the market continues to let the three-box design thrive.

The options here have changed a bit in the last few years, though, so how does the Lexus flagship, the LS fit into the picture? I drove one around for a week to find out.

2025 Mercedes-Benz GLC-Class Summary

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?

Verdict

The LS500 is the least logical version of the most logical option in the ultimate luxury sedan segment in which logic doesn’t often apply at all.

Take from that what you will, but if it was me being driven around I would definitely be opting for the hybrid version of the LS instead for its smooth electrified driving characteristics and lower operating costs.

Verdict

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.
