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 21 - 58 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.

For a convertible of this calibre, Mercedes E-Class Cabriolet running costs are not unduly expensive. Addmittedly servicing costs can be high but this is offset by the relatively frugal engine range - both in terms of emissions and economy.

Insurance isn’t cheap but it is on a par with alternatives, while the E-Class Cabriolet should depreciate at a slow rate.

Thanks to standard stop-start, accross the range, Mercedes E-Class Cabriolet emissions are surprisingly low - starting at 126g/km. Even the range-topping 327bhp E400 AMG Sport only chucks out 185g/km.

The new E200 engine uses a special lean-burn process to achieve some startline economy figures - 441.mpg. But it's the 47.9mpg and 156g/km E350CDI that impresses most.

Across the range, emissions and economy compare well with key alternatives from Audi and BMW.

Mercedes-Benz is back on form with its latest E-Class for build quality and durability, and the Cabriolet is no different. Previous engines have already been proven in other models, though the latest engines are relatively new. Still, we see no reason for concern and you can expect the Mercedes-Benz E-Class Cabriolet reliability to be trouble-free.
