Summary


The BMW Z4 is a two-seat roadster, with the current version being the third generation model. It was revealed in summer 2018 before going on sale in the UK in early 2019. It was jointly developed with Toyota, and forms the basis for the latest Toyota Supra coupé.

The current Z4 has a soft-top roof instead of a folding hard-top roof like the previous model as BMW has abandoned folding hard tops on its convertible models. The same move applied to the new BMW 4 Series Convertible that arrived in the UK in early 2021.

The BMW Z4 has received generally positive reviews from the UK motoring media, although several outlets have pointed out that it is more of a cruiser than a sports car.

The Z4 has been praised for its comfort, build quality and improved handling compared to its predecessor. However, it’s still not considered as enjoyable to drive as a Porsche Boxster or Audi TT, while the styling – as on most modern BMWs – has been polarising.

As of January 2024, the BMW Z4 has a New Car Expert Rating of B, with a score of 68%. That’s a combination of excellent scores for safety and reliability, middling media reviews and high running costs.

Reliability rating

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

The BMW Z4 has an excellent reliability rating of 87%, according to workshop data provided exclusively to The Car Expert by our partner, MotorEasy. Please note that this data covers all models in BMW’s Z Series, which includes all generations of the Z4, as well as the older Z1 and Z8 models.

Not many Motoreasy warranty holders have reported issues with their Z4, but data suggests that, if an issue is to arise, it will relate to the car’s suspension. This is a relatively cheap fix though, costing £250 on average to correct.

The BMW Z4 is not the best choice for those looking for an economical vehicle, data exclusively provided by our partner Clear Vehicle Data suggests.

Petrol models have a fuel economy ranging between 33 and 40 mpg, which falls below the market standard. This is of no surprise though, considering this is a sports car. The car’s insurance premiums will be fairly average by market standard, and the Z4 is estimated to be neither expensive or cheap to service and maintain over five years of ownership.
