Mercedes C-Class Estate review

The idea of a small estate car might sound like an oxymoron, but the truth is most people don’t need a boot that can swallow a sofa; instead they’re more likely to transport baby buggies or the family Labrador. And for tasks like that the Mercedes C-Class Estate could be just the thing.

More compact and affordable than the Mercedes E-Class Estate, it’s nonetheless available with a lot of the same technology, including a large, high resolution touchscreen and a wide range of electrified engines.

Indeed, there’s even a diesel plug-in hybrid version that promises to combine a long pure electric range with class-leading fuel economy when the engine does fire up.

So, is the Mercedes C-Class Estate actually one of the best estates on sale? And how does it compare with the rival Audi A5 Avant and BMW 3 Series Touring?

How fast is it and which engine is best?

All of the engines in the Mercedes C-Class Estate feature electrical assistance – not only to improve efficiency, but also to boost performance. However, you still have to work the entry-level C200 mild-hybrid petrol quite hard.

For a bit more low-end urgency – and therefore a more relaxing driving experience – you’re better off with the C220d diesel, which is also a mild hybrid. Meanwhile, the C300d uses a more powerful version of the same engine, cutting the 0-62mph sprint time from 7.5sec to 5.7sec.

Alternatively, there are two plug-in hybrid (PHEV) C-Class Estate models: the C300e petrol and the C300de diesel. These can officially travel almost 70 miles on pure electric power before they have to trouble their 2.0-litre combustion engines, which is farther than the rival Audi A5 Avant e-Hybrid or BMW 330e Touring.

What’s more, both C-Class PHEVs can get up to motorway speeds on electric power with little trouble. And in Hybrid mode, their engines fire up quickly to lend a hand when you put your foot down.
 

Is it agile and is the ride comfortable?

Most C-Class Estates come with Mercedes’ adaptive sports suspension set-up. However, the C300e and C300de upgrade this to air suspension at the rear in an effort to counter the weight of their PHEV batteries, which are located beneath the boot floor.

In Comfort mode, the adaptive suspension is very supple, allowing the car to soak up bumps and potholes better than an equivalent A5 Avant or 3 Series Touring, although the downside is a slightly floaty sensation over undulating roads.

To tame that, you’ll want to switch to Sport mode, which significantly tightens up the body control without making the ride overly firm. But while the C-Class Estate also benefits from steering that’s accurate and easy to gauge, it never feels as sharp or sporty as a 3 Series Touring.

PHEVs tend to be worse to drive than their mild hybrid equivalents, but the rear air suspension in the C300e and C300de quells the pendulum effect some rivals display during cornering. As a bonus, the PHEVs are the best-riding C-Class models of all, removing some of that float that you can experience in other versions.

Is it quiet and how easy is it to drive smoothly?

The C-Class Estate keeps engine noise to a minimum when cruising at  motorway speeds, and there's just a touch of wind noise from around the panoramic glass sunroof (when fitted). However, you do hear a fair bit of road roar on coarse surfaces.

There's also some buzz from the petrol engine of the C200 model when you rev it – as you’ll need to. So, overall the C220d diesel is actually more refined; it’s every bit as smooth as the BMW 320d Touring, although the Audi A5 Avant TDI 204 is quieter still.

The C-Class PHEVs are also impressively hushed – especially when running on electric power. However, you’re more aware of the engine cutting in and out in the C300de than the C300e.

It’s also worth noting that the brakes of the PHEVs aren’t as confidence inspiring as those in the mild hybrids, suffering from some mushiness in the middle of the long pedal travel as they switch from regenerative braking to mechanical braking.

“I’m a big fan of the nine-speed automatic gearbox that every C-Class Estate comes with; it shifts so smoothly that most of the time you don’t even notice its presence.”  – Oliver Young, Reviewer

What does the interior look like and is it well made?

The C-Class Estate is more solidly built than some other recent Mercedes models; its dashboard is largely free from creaks, and even if you tug at the infotainment screen it doesn’t flex all that much.

That said, the interior still looks classier than it feels to the touch. Yes, some appealing materials have been used, but there are also more hard, cheap-feeling plastics that you’d expect to find in a premium estate car like this.

The Audi A5 Avant has a slight edge for perceived quality, while the BMW 3 Series Touring feels considerably classier.

Is the driving position comfortable and is it easy to see out?

It’s easy to get comfortable behind the wheel of the Mercedes C-Class Estate. Not only is there a huge range of adjustment, including for lumbar support, but the seats move electrically and every trim except Urban edition lets you save your preferred settings.

Visibility is fine looking forwards, too. And while the placement of the rear head rests and the small rear window restrict your view of what’s behind, it’s no worse than it is in rivals.

As a bonus, even entry-level AMG Line models come with front and rear parking sensors, blindspot monitoring, a rear-view camera and powerful LED headlights. Then, if you upgrade to AMG Line Premium trim, Mercedes adds a 360-degree camera and fancier adaptive lights that can automatically adjust their output to stay on full beam without dazzling oncoming traffic.

Are the dashboard and infotainment system easy to use?

The interior of the C-Class Estate is dominated by digital displays. Alongside a crisp configurable instrument panel, there’s an 11.9in infotainment screen that can be operated by touch, voice commands, or by using some controls on one of the steering-wheel spokes.

The infotainment screen responds quickly to inputs and has super-sharp graphics, although BMW’s iDrive system is easier to use on the move, thanks to physical shortcut keys and a rotary scroll dial.

Apple CarPlay and Android Auto are included as standard in the C-Class Estate, plus there’s wireless phone-charging and two C-USB sockets in the centre console to top up your devices.

“Mercedes isn’t the only German brand that’s taken some of the money out of its interiors in recent years, but I still find it a little disappointing that the C-Class is so obviously built to a price.” – Dan Jones, Senior Reviewer

How much space does it have for people?

You’ll have plenty of room in the front of the Mercedes C-Class Estate helped by seats that go back a long way on their runners. Plus, rear knee room is decent. However, if you carry six-footers in the back of your car, they might have to slouch a bit.

In addition, the rear of the car is only really comfortable for two because the central seat is narrow and its occupant has to sit with their legs either side of a large lump in the floor.

There are several useful storage areas inside the car, including large door bins and a cubby beneath the centre console armrest.

How much room is there for luggage?

Mild hybrid versions of the C-Class Estate have a boot capacity of 490 litres (beneath the luggage cover and including underfloor storage), which is more than you get in an equivalent Audi A5 Avant, but a little short of what a BMW 3 Series Touring offers. Meanwhile, the Skoda Superb Estate and Volkswagen Passat. blow them all away, with 690 litres.

Perhaps a bigger problem, though, is that the C300e and C300de lose the underfloor storage area to their batteries, with these also requiring the boot floor to be raised slightly. This reduces space to just 360 litres – pretty much identical to the capacity of the A5 Avant e-Hybrid, but 50 litres down on the 330e Touring’s.

On the up side, all C-Class Estates come with 40/20/40 split and fold rear seats, a powered tailgate and a motorised luggage cover. Meanwhile, loose items can be held in place using either the four rings provided in each corner, the straps and netting on the sides, or one of two bag hooks.

“It might not be huge by estate standards, but the boot of the C-Class would still be plenty big enough for my family’s needs.” – Steve Huntingford, Editor

How much does it cost?

The Mercedes C-Class Estate is priced a few thousand pounds higher than the Audi A5 Avant and BMW 3 Series Touring. However, because the plug-in hybrid versions are capable of covering almost 70 miles on pure electric power, they attract fairly low company car tax bills.

In addition, while most PHEVs are actually quite thirsty once they’ve run out of battery power, the C300de has a 2.0-litre diesel engine to fall back on, so delivers – well – diesel-like efficiency.
 

What equipment do you get?

The cheapest trim for mild hybrid versions is AMG Line, which includes 18in alloy wheels, keyless start, dual-zone climate control, heated front seats and ambient interior lighting.

We’d still be tempted to step up to mid-spec AMG Line Premium, though, because this brings an electrically adjustable steering wheel, keyless entry and augmented-reality navigation – in addition to the upgraded headlights and camera system mentioned earlier.

Then sitting at the top of the range you have AMG Line Premium Plus, which adds 19-inch wheels, a panoramic glass sunroof, a head-up display and an excellent Burmester surround-sound system.

As for the PHEVs, these get their own entry-level trim, called Urban Edition, which is similar to AMG Line, but swaps out memory front seats in favour of a panoramic glass sunroof.

Is it reliable and how long is the warranty?

The C-Class was the worst performing executive car in the 2025 What Car? Reliability Survey, with 43% of the owners who contacted us  reporting a fault, and 39% of those issues serious enough to stop the car from being driven.

It’s just as well, then, that you get a three-year, unlimited-mileage warranty and three years of breakdown cover, which is similar to BMW's offering. Audi's warranty, by contrast, expires after three years or 60,000 miles – whichever comes first.

How safe is it, and is it easy to steal?

When it was crash tested by Euro NCAP in 2022, the C-Class was awarded five stars out five, after scoring very well for occupant protection. 

The A5 Avant and 3 Series Touring also scored five stars when they were tested in 2024 and 2019 respectively, but because Euro NCAP revamps its tests every couple of years, drawing direct comparisons with the C-Class’s results is impossible.

As you’d expect, the C-Class comes with a Thatcham Category 1 alarm and engine immobiliser system.

“The one thing that makes me feel a bit better about the C-Class’s reliability issues is the fact that Mercedes performed all repairs for free.” – Claire Evans, Consumer Editor
