BMW Z4 roadster - Reliability & safety
Five-star safety rating but BMW Z4 owner satisfaction remains to be proven
BMW is one of the respected German 'Big Three' premium brands. All three have a desirable, high-quality reputation, yet neither BMW or its Audi or Mercedes rivals are exactly top-ranking where it comes to owner satisfaction. The Z4 scored the full five stars when it was tested by Euro NCAP, thanks in part to a healthy list of crash-avoidance technology available as standard or at extra cost.
BMW Z4 reliability
BMW finished 21st out of 29 manufacturers in our 2021 Driver Power owner satisfaction survey behind Mercedes in 13th and just ahead of Audi in 23rd.
The BMW Z4 achieved a five-star safety rating from Euro NCAP, including an impressive 97% score in the adult occupant category.
The Z4 has all the safety equipment you'd expect of a new car these days, from mandatory kit such as anti-lock brakes (ABS), stability control and tyre pressure monitoring, through to today's must-haves such as autonomous emergency braking. However, it's on the options list that you'll find the most impressive technology, with driver-assist systems like adaptive cruise control, lane keeping assist and reversing assistance only available at extra cost.
The same is true of the clever adaptive LED headlamps, whose main beam will adjust in shape to avoid dazzling oncoming traffic at speeds of 44mph and above.
