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 32 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 Z4 is not as expensive to run as you’d imagine and the 3.0-litre engine is capable of 33mpg but servicing, parts and the run flat tyres aren’t particularly cheap. On the plus side BMW offers a servicing package on new cars called Service Inclusive whereby one up front payment covers all servicing costs for five years or 60,000 miles (whichever comes first).

The good news is that this can be passed on when selling.

Considering the performance available, the Z4 isn’t too bad in terms of efficiency. It emits 207g/km of CO2 and is capable of 33mpg.

The Z4 has been around since 2003 and has been very reliable, so the Coupe should be similarly reliable. Lacking the convertible roof means there’s one less thing to go wrong too while the engine has been well proven in other models.
