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 - 48 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 four cylinder petrol units offer respectable economy, whilst the diesels are positively frugal. But the V6 units start to look a bit on the thirsty side unless extreme restraint is exercised – the V8 even more so. Insurance groups range from 10 to 19. However the biggest cost of ownership is likely to be depreciation which is comparable to a Ford Mondeo.

ZT is quite a polluting model. With an average of 220 g/km CO2 across the line-up, its emissions are a little high for an executive saloon. The range is not very frugal, averaging 33 mpg.

The 75 on which its based was originally engineered by BMW which is good news for the reliability, although to their credit, build quality actually get even better when production moved to Longbridge so reliability should be good.
