This generation of Mercedes-Benz C-Class arrived in 2021. It was an evolutionary step forwards over its predecessor rather than a seismic shockwave of innovation as it’s based on the same underpinnings as the old model. That’s not to say Mercedes hasn’t been busy though, as the car is now exclusively hybrid powered and almost every component (and especially those you interact with when driving) has been replaced or modified to make it better.

In addition to the technical upgrades, Mercedes has dragged the C-Class’s styling into step with the rest of its line-up. Now, it looks even more like a Mercedes E-Class that’s been washed on the wrong cycle, while the cabin lifts several design cues from the company’s range-topping Mercedes S-Class.

The C-Class’s biggest problem is buying trends. It’s a compact four-door saloon gasping for air in a crowded marketplace of family-sized SUVs, with tough competition from the likes of the BMW X3, Audi Q5, Volvo XC40 and Mercedes’s very own GLC SUV.

Despite the saloon car’s waning popularity, Mercedes still plans to sell a truckload of C-Classes. The brand’s engineers have worked hard to make the latest model desirable because, as the market tightens, each vehicle in it needs something unique to set it apart from its peers. For example, the BMW 3 Series sells on its engaging driving experience, while the Audi A4 majors on comfort and refinement. The C-Class aims to beat both its main rivals on the technology front.

Step inside and the first thing you notice is the vast 11.9-inch portrait infotainment screen and accompanying 12.9-inch digital instrument display. Both look great and, once you’ve learned your way around their menus, they’re pretty easy to use. The screens will certainly be a conversation starter for new passengers, too.

There are two petrol engines, two diesel engines and a plug-in hybrid powertrain to choose from, in addition to a trio of trim levels. The sporty models are now sold under the Mercedes-AMG banner – and there are only two of those available for now. This is practically austere in Mercedes terms. The previous-generation model was fitted with a staggering range of 17 different engines during its life.

If you want a premium-badged, four-door saloon, the Mercedes C-Class could serve you well. The question is, should you take one over a BMW 3 Series or an Audi A4? Over the next few pages, we’ll aim to answer that question. Our review will rank the C-Class’s practicality, comfort, technology, running costs and driving experience against its rivals – and then we’ll offer our verdict on the car.
