Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 28 - 68 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Mercedes-Benz C-Class running costs can vary wildly depending on your choice of engine. Pricing is at a similar level to the previous generation model – in fact you actually get more car for your money if you take into account the superior specification and safety equipment. The C-Class will hold onto its value better than the Audi A4 and about the same as a BMW 3-Series saloon.

Fuel consumption – for both petrol and diesel engines is good, although customers of the top models will be in the higher bands for road tax. Servicing at Mercedes-Benz dealerships can be expensive, but the network of specialist independents is much more affordable.

Mercedes-Benz C-Class emissions are relatively green and easy on the environment depending on which engine you pick. Mercedes has introduced BlueEFFICIENCY – it’s version of BMW’s Efficient Dynamics – to the range. It means the C220 CDI offers 117g/km carbon dioxide emissions and 64.2mpg when ordered with a six-speed manual gearbox.

You shouldn’t have much to worry about regarding Mercedes-Benz C-Class reliability. By its own admission, the company’s standards have fallen in recent years and reliability hasn’t lived up to the company’s reputation. This C-Class is designed to address that and has had extensive development. It certainly feels well built as a result but the proof as to whether this has been successful will come with reports from buyers in our owners’ reviews section.
