4.0 out of 5

As the Insignia was released fairly recently, there were not enough responses from Insignia drivers for the Gran Sport to be included in the top 100 cars featured in our 2019 Driver Power Survey. A five-star Euro NCAP crash safety score is certainly reassuring though.

Vauxhall Insignia Grand Sport reliability

Vauxhall had a poor time of it in our 2020 Driver Power customer satisfaction survey, coming 29th out of 30 manufacturers. Of the owners that responded, 13.7% experienced a fault with their Vauxhall in the first 12 months. We can only hope the solid-feeling Insignia Grand Sport is more reliable than the outgoing Insignia, which came 136th out of 150 cars in our 2016 poll – but cars do tend to drop down satisfaction surveys as they near the end of production.


Euro NCAP has awarded the Insignia Grand Sport with the full five stars after crash testing, which is good news for drivers and families alike. Scores of 93% and 85% in the adult and child occupant protection categories equate to excellent protection in a collision.

All Insignia Grand Sports come with autonomous emergency braking (AEB), which will automatically stop the car for you if it detects a potential collision that you fail to take action to avoid. The Insignia’s system works at urban speeds, which is arguably where it’s most needed: experts reckon 75% of all collisions occur at under 25mph and AEB reduces rear-end collisions by 38%. Should you have a crash, Vauxhall’s OnStar system will automatically contact the emergency services for you, but it’s a £415 option. There’s a system that measures, in seconds, how far you are away from the car in front (allowing for easy checking of the two-second rule) and lane-departure assistance, which will help keep you in lane if you swerve out without indicating.

That roster of protective technologies is in addition to mandatory features like a tyre-pressure warning system, electronic stability control and the essential (but interestingly, not mandatory) complement of airbags.
