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 24 - 37 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.

If you opt for a diesel then you can expect reasonable fuel bills although it’s not exactly frugal. Servicing is expensive, especially at Mercedes dealers but it’s essential if you want to get the best price on the second hand market.
The CLS is a polluting model and with an average of 260g/km CO2 across the line-up, its emissions are quite high for a sports coupe. The range is also thirsty, averaging just 28mpg.
We have some reservations over reliability because the CLS is based on the 2002 E-Class, and the first few years of new E-class ownership haven’t been plain sailing for all drivers with a spate of electrical glitches reported. Hopefully, these have been ironed out three years down the line with the CLS.
