Mercedes C-Class review

A quality interior, great efficiency and strong on-board tech mean that the Mercedes C-Class is a deeply impressive compact executive saloon

  • Improved on-board tech
  • Plug-in hybrid option
  • Cabin quality

  • Bigger wheels affect ride comfort
  • Smaller boot than some rivals

The latest Mercedes C-Class saloon has given buyers looking for a compact executive car much to think about. It offers a sharp new look, heavily inspired by its bigger E-Class sibling, outstanding levels of comfort and strong on-board technology. All this, plus the C-Class features interior quality that puts much more expensive models to shame.

If you factor in the improved efficiency of the mild-hybrid petrol and diesel versions, along with the introduction of new plug-in hybrid models, the C-Class makes a compelling case for itself and should be one to consider.

About the Mercedes C-Class

Over recent years, the popularity of traditional petrol and diesel saloon cars like the Mercedes C-Class has been on the wane. High-riding SUVs continue to capture the hearts of buyers, and it’s a trend that hasn’t been lost on Mercedes, because it has redoubled its efforts with the latest C-Class to deliver improvements across key areas to help it stay competitive. Exterior styling, on-board tech, ride and comfort have all been thoroughly revised, while the most appealing update for cost-conscious buyers will be the introduction of new mild- and plug-in hybrid models.

The C-Class engine range is made up of four-cylinder petrol and diesel units, all featuring 48-volt mild hybrid assistance to help improve efficiency. The entry C 200 has a 1.5-litre petrol powerplant developing a healthy 201bhp, although you can upgrade to the more potent 2.0-litre C 300 with 254bhp. Diesel power for Mercedes’ executive saloon consists of the 197bhp C 220 d, and the C 300 d which produces 261bhp. All use a standard nine-speed auto gearbox.

By far the most efficient model in the C-Class line-up is the C 300 e petrol plug-in hybrid, which offers a claimed 68 miles of all-electric drive and, provided you regularly top up the 25.4kWh battery, should drastically cut down on visits to the fuel station.

Mercedes has kept the trim line-up for the new C-Class pretty straightforward and easy to understand: the familiar Sport specification is the entry point to ownership, followed by the popular AMG Line which can be upgraded with Premium and Premium Plus packs.

Competition to win over buyers in the executive saloon market is stronger than ever, with the C-Class not only facing up to German rivals the BMW 3 Series and Audi A4, but also rivals such as the Alfa Romeo Giulia and Jaguar XE which look fantastic and are great fun to drive. The Volvo S60 offers its own brand of subtle, sporting luxury with powerful petrol engines and the advantages of plug-in hybrid technology, while the Genesis G70 is a Korean newcomer that’s an intriguing alternative.

New pure-electric models offer further opposition to the executive saloon establishment, with the Hyundai Ioniq 5, Kia EV6 and Polestar 2 all delivering low running costs, while the Tesla Model 3 has brand appeal strong enough to meet the C-Class head on.

Used and nearly new

Buying a used Mercedes C-Class means you'll benefit from superb comfort, decent levels of kit and a classy looking interior. Nearly new cars will still be relatively expensive to buy, while the C-Class can be pretty costly to run, with insurance premiums and servicing costs reflecting the fact that it's a premium compact executive car.

There should be a lots of examples to choose from as the C-Class has always sold well in the UK, but make sure, as ever, that your purchase comes with a good history and evidence of servicing and maintenance.

Mercedes C-Class history

C-Class

Mercedes C-Class Mk4: 2014-2021

The Mk4 Mercedes C-Class will definitely appeal to those looking for a capable compact executive car. Available as either a saloon, estate, coupe or convertible model, the C-Class offers a sense of style and relatively-affordable luxury that more mainstream rivals such as the Ford Mondeo and Volkswagen Passat just can't match.

The C-Class range was given a refresh in 2018 where, alongside some subtle exterior tweaks, new C300e petrol and C300de diesel plug-in hybrids were introduced offering improved fuel economy and tax savings for company car drivers. Read our full Mk4 Mercedes C-Class buyer’s guide here…
