How much is it going to cost to run?

In four-cylinder guise, the E-Class Coupe should prove affordable to run, with the E 220 d achieving the best mpg figures, while emitting tax-friendly levels of CO2 official figures, which will appeal to private and business users alike.

MPG and CO2


  • E 300: 35.8-36.2mpg, 178g/km CO2
  • E 450 4Matic: 31.7mpg, 201g/km CO2


  • E 220 d: 47.9mpg, 155g/km CO2
  • E 300 d: 44.1-44.8mpg, 167g/km CO2
  • E 400 d: 39.2mpg, 194g/km CO2

Go for the four-cylinder petrol E 300 and you’ll see claimed economy figures of 35.8mpg, but even the E 450 4Matic is quoted at 31.7mpg with 201g/km, which is impressive for a relatively heavy car with such strong performance. You’d do well to achieve this in everyday driving though, especially if you make an attempt to use the performance on tap.

Sitting between the E 220 d and E 300 for claimed fuel economy is the E 300 d. Mercedes-Benz claims it’ll return up to 44.8mpg, which is impressive considering the punch delivered by its four-cylinder diesel.

Top honours for emissions go to the E 220 d. With CO2 emissions of 155g/km, it falls into a tax band usually occupied by smaller family cars. Whether you go for the standard 19-inch alloy wheels or larger 20-inch items, CO2 emissions are the same. 

Servicing and maintenance

Mercedes-Benz Service Care allows owners to guarantee all parts and labour costs for up to three services, while spreading the cost over monthly payments. If you pay upfront, any remaining services are automatically passed on to the next owner. You’ll need to visit the Mercedes website to get a personalised quote, but it’s a nice way of avoiding nasty surprises.

Insurance costs are likely to be quite high as well, as the E-Class is an expensive and desirable car. Entry-level diesel models are the lowest for insurance, while the six-cylinder diesel and petrol models are the highest.


  • Merc has improved quality in recent years
  • Current E-Class proving solid and reliable
  • No recalls for the latest model

You should be able to rest easy that the E-Class Coupe should prove reliable. Mercedes-Benz has worked to improve its reputation in recent years, and its latest raft of models all feel very solidly built from plush materials and now-proven parts.

The E-Class Saloon with which it shares its underpinnings and parts hasn’t been the subject of any recalls, so that should be enough to keep any concerns at bay.
