It must be a hard life being a German compact executive car when your opposition keep stepping up their game with every new model and facelift. Well, the BMW 3 Series and Audi A4 have something new to quiver over in the 2021 Mercedes C-Class.

Though the mild exterior changes might lead you to think this is little more than a half-arsed facelift, there’s a lot of new stuff going on in the cabin and under the skin. With the previous car selling 2.5 million units since launch in 2014, this sixth-generation model has a lot to live up to.

We got our hands on a German-spec, left-hand drive model for a few hours on the roads around Mercedes’ Milton Keynes HQ.

What’s new for the 2021 C-Class?

Well, it looks pretty similar to the outgoing car. The underlying platform is the same, but virtually no stone has been left unturned, and certainly everything that the driver interacts with is all-new.

It’s slightly longer, wider and lower than it was, but the cab-rearwards silhouette is familiar. As for the styling, it’s the good old Russian doll effect – it looks like an E-Class that’s parked further away. Vertical taillights make way for horizontal ones, there are slimmer headlights and the grille has been flipped upside down. Incremental stuff that’s unlikely to offend, and in the right colour and trim we reckon it looks rather good.

The wheelbase and tracks are longer while the suspension remains double wishbone at the front and multi-link at the rear. It’s worth mentioning from the outset that our German-spec car was fitted with adaptive dampers and rear-wheel steering – neither of which will be offered to UK buyers.

What about inside?

Seen any pictures of the latest S-Class? You’ll know what to expect in the C. It’s a massive departure from before, and centred around two vast screens – 12.9 inches for the driver and a portrait-oriented 11.9 inches for the infotainment.

The central screen controls more than just music and sat-nav, with even the climate controls positioned in the lower third. Very surprisingly, though, it’s remarkably easy to use.

It's based around personalised profiles, and you’ll be able to sign in with a built-in fingerprint reader to have the car know things like your seat position, preferred radio station and typical satnav destinations.

Better than buttons? Of course not. But better than just about any other primarily touchscreen-driven interior we’ve used of late. The screen is bright, clear and responsive, the layout makes sense, and perhaps thanks to the shallow angle of the display everything’s very easy to hit even with an unsteady hand.

The switchgear all feels top-shelf in terms of quality and there are some useful, usable touches – such as standard wireless phone connectivity and a wireless charging tray that keeps your smart device out of sight and temptation.

A couple of criticisms – one is that the screen does tend to catch the light more than a more vertically-positioned one would. This will likely only be an issue in top-spec cars with the panoramic sunroof, but it’s still annoying.

The other is more damning, and it’s that there’s a general lack of space inside the C-Class. Four six-footers will be snug, and headroom in the back is limited. The wide centre console makes the front passenger footwell very narrow, too.

The boot’s reasonably well-shaped, but 25 litres smaller than that on the 3 Series or A4 – though the Estate does go some way to addressing this.

What engines are there?

From launch, four – two petrols and two diesels, all with mild-hybrid tech to boost efficiency and responsiveness. The integrated starter motor offers 20bhp extra to reduce turbolag and a further 27bhp of overboost when you floor it.

The 201bhp C 200 sounds attractive with its 7.3s 0-62mph time, but it’s only a 1.5-litre and sounds a bit strained when you rev it. The 2.0-litre C 300 should be rather more perky thanks to its 254bhp output and 6.0s 0-62mph time – it’s only available in the Saloon, though, and not the Estate.

In reality, though, most will opt for one of the diesels. We drove the C 220 d, which is a 2.0-litre with 197bhp. It’s about as good a match for the C-Class as anything, thanks to an easily-ridden wave of torque and a nicely slushy nine-speed auto. It’s also commendably quiet.

You can also go for the more powerful C 300 d, with 261bhp, 0-60mph in 5.7 seconds and 155mph top speed.

If that sounds like an uninspiring range, it is. They’re pragmatic and promise strong efficiency but so far there’s almost zero excitement to be had. And there are a few niggles – a decidedly mushy brake pedal, for one, and a tendency for the gearbox to thump when you put your foot down.

Later on in 2021 there’ll be a petrol plug-in hybrid – this promises over 60 miles of all-electric range, which is an impressive figure. A diesel hybrid and AMG models will follow in 2022 – the latter eschewing its predecessor’s V8 for a four-cylinder hybrid setup.

Any good to drive?

Keen drivers will still appreciate the BMW 3 Series more, but the C-Class doesn’t disgrace itself – as with the engine lineup, it’s very competent if a little unexciting.

The steering’s nicely weighted and direct, while the handling is without drama. The real focus is on comfort – the C-Class irons out bumps around town and effortlessly floats down a faster road. But, as mentioned earlier, our test cars had the adaptive dampers – so we’ll hold off on this judgement until we try the passively-sprung UK cars.

The same goes for the rear-wheel steering, which gives the Merc a commendable sense of agility but once again won’t be offered in the UK.

Verdict

Early signs are very promising for this new compact exec. It’s a hackneyed turn of phrase to say it’s like a baby S-Class, but with this new generation that’s closer to the truth than ever before.

Thanks to that brilliant dashboard and touchscreen this feels a generation removed from its 3 Series and A4 rivals – a trend that may well continue when the engine range is fleshed out with more up-to-the-minute PHEV options.

Practicality concerns plague the C-Class and raise questions about its use as anything but a rep’s mile-muncher, and of course the whole shebang may come unstuck if the UK-spec cars lose the adaptively-sprung model’s pillowy ride comfort.

But, so far at least, it’s looking good for the sixth-gen C-Class. We’ll bring you a review of the UK model as soon as we’ve driven it.
