Reliability & safety Rating

4.0 out of 5

Although the Porsche 718 Cayman isn’t likely to go through Euro NCAP crash-testing, its mid-engined design means it has an inherent advantage when it comes to safety. Similarly, the Cayman was too niche a model to have featured in our 2020 Driver Power customer satisfaction survey, but Porsche has an enviable reputation when it comes to owner contentment.

Porsche 718 Cayman reliability

Porsche has done well in past Driver Power polls, with a seventh-place finish out of 32 carmakers in 2016, but too few owners responded for Porsche to feature in our latest results. Owners rate the build quality evident in Porsches and also praise their cars’ road handling and comfort – a difficult pair of characteristics to balance, but areas where the 718 Cayman impresses. Making predictions about reliability is unwise, but while Caymans and Boxsters from the early-to-mid 2000s have a patchy record for dependability, this isn’t true with later cars, which have proven to be robust.


Being a mid-engined car means that in the event of a frontal impact, the 718 Cayman’s bonnet can act as a crumple zone, absorbing the energy and forces from the collision. Porsche has also engineered crumple zones in the rear, while the 718 Cayman has super-stiff doors to help maintain the integrity of the passenger compartment, as well as thorax and head airbags. The driver and passenger airbags are clever items that can inflate to two different stages, depending on how serious the crash is.

It's possible to boost safety further by delving into the options list, with an ISOFIX child seat mounting point for the passenger seat, lane change assist, speed limit indicator and adaptive cruise control (that can also boost braking in an emergency stop) all available.
