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 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.

The Cadillac badge has negligible brand value in the UK at the moment, which means its residual values won’t be as strong as established premium manufacturers. However its limited numbers and likely appeal to early adopters ought to ensure it fairs better than run-of the mill brands. It won’t be a frugal choice and a diesel engine is still a long way off too.

On the other hand it is generously equipped and represents good value for money.

CTS is a polluting model. With an average of 277 g/km CO2 across the line-up, its emissions are high for an executive saloon. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is disappointingly thirsty, averaging 24 mpg.

It’s new to the UK so how this newly developed right hand driver will perform remains to be seen, but the American market is utterly intolerant of unreliability and this model seems to fare pretty well in their reliability surveys.
