Lexus RX350H vs Mercedes-Benz C350

What's the difference?

The Lexus RX holds broad appeal. Families with a bit of money that don’t need a third seating row, older people who love the brand and want a bit of space, and people stepping up into the premium marque from a mainstream brand are all potential buyers. 

The fifth-generation version that launched in early 2023 proved to be a significant step up over the previous RX.

Lexus made it more dynamically capable, and there’s been a sharpened focus on refinement, value-for-money and safety credentials. 

We spent three weeks getting to know the most affordable RX - the entry-grade Lexus RX350h Luxury two-wheel drive - to see whether it’s worth putting it at the top of your premium family SUV shopping list.

If you’re picturing the premium mid-size segment in Australia, you’re almost certainly picturing Mercedes-Benz. Honestly, the premium carmaker has the kind of powerful and unquestioning stranglehold on the segment that would have despots and dictators turning green with envy.

The C-Class often outsells its nearest competitor by a factor of two to one. Even more impressive, that nearest competitor is another Mercedes, the CLA. Audi and BMW are left off in the middle distance, duking it out for third and fourth place.

So yes, the C-Class is a very important car for Mercedes. And this new one, updated for 2019, is even more so. It’s the first major update in the current car’s four-year lifespan, with a handful of exterior tweaks, some new key cabin technology and, most importantly, a new and clever engine option for its top-selling version.

So is that enough to keep the C-Class at the top of the mid-size pile?
