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 - 50 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 has fine-tuned the C-Class Sports Coupe’s ageing engines, but the CLC can’t compete with the BMW 1-Series’ significantly lower emissions and better fuel economy. This means dearer road tax and more frequent trips to the fuel pumps for owners. Mercedes servicing is also renowned for being very expensive, even by premium car standards.

The CLC’s engines are greener than before and every model, except C350, emits less CO2 and returns better fuel economy. As you’d expect the diesels are eco-friendliest: the CLC 200 CDI emits 152g/km CO2 and achieves 48mpg. The CLC’s green credentials aren’t class-leading, but a worthwhile improvement nonetheless.

Mercedes-Benz has built reliable cars in recent years. The previous C-Class Sports Coupe is solidly-constructed and the new model shouldn’t be any different. As ever, regular maintenance and adherence to service schedules will help sustain trouble-free ownership for tens of thousands of miles.
