Five years since its debut, the fifth generation C-Class has received an update. Packing revised powertrains, new infotainment software and a revised visual identity, Mercedes-Benz calls it the most comprehensive technical upgrade in the model’s history.

The facelifted model features a large singleframe grille as seen on the new electric C-Class, plus new headlight clusters with star-shaped running lights. The saloon gets star lights at the rear, while the estate continues with the same multi-segment horizontal strip it originally launched with. All UK-bound examples have AMG Line styling, with a prominent front splitter and rear diffuser, large bumper inserts, and 18” or 19” alloys.

Beyond the front bumper and the contents of the wheel arches, the majority of the design is carried over from the pre-facelift model. Likewise, the double-bulged bonnet returns, but a revised engine is found underneath it. Codenamed M254 Evo, the familiar 2.0-litre petrol engine has gained Euro 7 compliance, and an electric compressor to minimise turbo lag. In the C250, this generates 215bhp and 236lb-ft (320Nm), while the C300 develops 254bhp and 295lb-ft (400Nm). Both derivatives are assisted by a 48-volt mild hybrid system, with an integrated starter-generator offering boosts of 23bhp and 151lb-ft (205Nm) when required.

The C300e is the plug-in hybrid option, featuring an uprated electric motor and a combined output of 322bhp and 406lb-ft (550Nm). Its 19.5kWh battery is good for 67 miles of electric-only range, and 55kW DC charging capability means a 10-80% top-up takes just 20 minutes on a public outlet. Home charging will require just under three hours. The OM654 diesel engine has attained Evo status with increased biofuel compatibility, but is absent from the C-Class facelift line-up in the UK.

New tech is found inside, with new MB.OS software packing a trio of AI models from ChatGPT, Microsoft and Google. As well as controlling vehicle functions – including activating the driver’s heated seat if they don’t fancy reaching for the button on the door card – the virtual assistant can give detailed answers to questions about currency exchange rates, and even ski slope conditions. The dual display layout is familiar, with a 12.3” instrument cluster and an 11.9” portrait infotainment touchscreen angled at 6° towards the driver. 

The navigation system is now based on Google Maps, and physical switches for adjusting volume and cruise control settings have returned to the six-spoke steering wheel. Elsewhere, there’s two ISOFIX anchor points on the rear bench, a 455-litre boot in the saloon, and a 490-litre load bay in the estate. Owing to the placement of the battery above the driven axle, luggage capacity for the C300e drops to 316 and 360 litres in the saloon and estate respectively.

Four equipment levels will be available at launch, beginning with the Urban Edition. The entry-level variant includes AMG Line styling with the Night Package adding high-gloss black exterior trim. Heated front seats, 64-colour ambient lighting, wireless smartphone charging and mirroring, LED headlights, rear privacy glass, and a powered tailgate for the estate all come as standard. AMG Line Premium switches the black exterior trim for silver, adds a panoramic sliding sunroof, Digital Light adaptive headlights, an illuminated grille, memory seats, 360° camera, heated steering wheel, and keyless entry.

AMG Line Premium Plus models gain the Burmester 3D surround sound system, head-up display, and detailed logo projectors in the headlights and doors. The range-topper is the Premier Edition, including the Night Package, nappa leather upholstery, a black lip spoiler for the saloon, and the Refinement Package.

Three options packages are available: the Luxury Interior adds massaging front seats with ventilation and heated outer rear seats, while the Refinement Package adds Dynamic Body Control adaptive dampers and 2.5° rear-axle steering to non-plug-in hybrid variants. All models can pull up to 1,800kg braked, and a factory-fitted trailer coupling includes extra ESP coding for improved stability when towing.

There’s more to come from the new C-Class, with the AMG C53 set to be announced in the near future. As with the recently revealed GLC53, a mild-hybrid straight-six will replace both previous four-cylinder powertrains used in the C43 and C63 S E hybrid. There are no plans for a return to V8 power.

While plenty has changed as part of the facelift, a lot has remained the same for the fifth generation C-Class, suggesting its life cycle has been extended beyond the standard seven years. A similarly light update was seen on the GLE and GLS in 2023, before new styling and a revamped interior landed in 2026.

As such, we suspect the W206 and S206 are here to stay for the foreseeable future, but don’t rule out another facelift in the next few years. The updated C-Class is on sale now in the UK, with prices starting from £46,995 for the saloon, and £48,745 for the estate. Production commences in October, and the first examples should arrive in showrooms at the tail end of 2026.
