Mercedes E-Class Cabriolet (2010-2017) - MPG, running costs & CO2

Thanks to a range of BlueTEC engines, the E-Class Cabriolet manages to be fairly economical. The most fuel-efficient model will return more than 55mpg and emissions across the board aren’t as big as you might think. In terms of selling, most buyers should recoup a decent amount of their money, as convertible cars are usually desirable, particularly in the summer months. 

Where the E-Class Cabriolet falls down, though, is in terms of maintenance and insurance. The Cabriolet is broadly more expensive to insure over the coupe, while its rivals from other German premium brands also do much better overall on insurance premiums.

Mercedes E-Class Cabriolet MPG & CO2

CO2 emissions for the E350 BlueTEC model have been reduced from 154g/km to 140g/km thanks to a new 9G-Tronic automatic gearbox, while fuel economy is up from 48.7mpg to 51.4mpg. But if rock-bottom running costs are your priority, go for the E220 BlueTEC, which will return 57.7mpg and emits just 126g/km of CO2.

15

The four-cylinder petrol engine in the E200 returns fuel economy of 44.8mpg and has CO2 emissions of 146g/km. The bigger V6 petrol engine in the E400 will cost more to run, returning 39.2mpg. 

Insurance

The Cabriolet sits between insurance groups 37 and 42. In comparison, the coupe’s insurance groupings are between 36 and 44, while the BMW 4 Series Convertible has lower groupings, as it’s placed between group 30 and 39. The Audi A5 does even better, as the lowest group in which it can be placed is 26.

Warranty

Mercedes offer a three-year/unlimited mileage warranty on all of their new cars. It’s about the same as most other premium car brands like BMW and Audi in terms of length.

Servicing

Mercedes recommends having the car serviced every year or every 15,500 miles – whichever is soonest. The German manufacturer also offers a fixed servicing plan from £24 per month for two services over two years.
