Mercedes-Benz C-Class (2022-present) Pros and Cons

Pros	Cons
The PHEV has a class-leading electric range	Not as sharp to drive as a BMW 3 Series
Beautifully finished interior	There are roomier cars for less money
MBUX infotainment system looks stunning	Bland styling

Quick Summary

The fifth-generation Mercedes-Benz C-Class is a premium executive car available as a saloon or estate. It offers a range of mild-hybrid petrol and diesel engines, but its standout feature is the C300e plug-in hybrid (PHEV), which boasts a class-leading official electric range of up to 68 miles. The C-Class's interior is a highlight, featuring a high-quality finish and the stunning MBUX infotainment system with its large, clear screens. Practicality is adequate, but rivals like the Audi A4 offer more passenger room, and the PHEV’s boot space is reduced to 315 litres.

On the road, the C-Class is a composed, refined, and comfortable cruiser, with the PHEV model being exceptionally quiet in electric mode. While it is satisfying to drive, it doesn’t offer the same level of driver engagement or sharp handling as a BMW 3 Series. Standard equipment is generous across the range, but some desirable features like adaptive cruise control are reserved for expensive option packs. The C300e is a particularly compelling choice for company car drivers due to its low tax rating, making the C-Class a strong contender for those prioritising comfort, technology, and efficiency.

Best for: Buyers who value a premium interior, cutting-edge technology, and a comfortable ride, especially those interested in the class-leading C300e plug-in hybrid.

Not ideal for: Drivers who prioritise sporty handling, maximum interior and boot space, or those who want all-wheel drive without choosing a high-performance AMG model.


Comparison vs Key Rivals



The Verdict

You should buy the C-Class if: You want a refined executive car with a stunning, tech-forward interior and access to a class-leading plug-in hybrid powertrain.

Consider alternatives if: Your top priority is sporty handling, maximum passenger and boot space, or you need all-wheel drive on a non-performance model.

Competitive Position: The Mercedes-Benz C-Class is a deeply impressive executive car, defined by its high-quality cabin and advanced technology. The C300e plug-in hybrid version is a standout choice thanks to its exceptional electric range. However, it faces stiff competition from the sharper-driving BMW 3 Series and more spacious Audi A4, placing it as a luxurious and comfortable choice that doesn't lead the class in every area.
