What is miles per pound?
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 19 - 20 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.

As you’d expect of a car with a price tag of more than £70,000, the CLS AMG is expensive to run. Fuel economy is a woeful 20mpg and filling up the 80-litre tank won’t be cheap. Items such as tyres and brake pads are expensive while Mercedes dealer servicing is renowned for being pricey too. Unsurprisingly, insurance is group 20.
With emissions of 345g/km of CO2 and fuel economy of just 20mpg it’s little surprise that the CLS AMG gets a rock bottom score.
The hand-built engine in the AMG will need looking after, but as long as it is serviced according to schedule there should be no problem.
