BMW i8 Coupe reliability & problems

As we’ve mentioned, despite the advanced nature of the i8’s chassis and engine, we’ve not heard of any reliability problems with the car.

The 1.5-litre turbo petrol engine is shared with sister brand MINI, and although it’s in a higher state of tune than in the small British hatchback, it’s a reliable unit.

BMW didn’t perform too well in our sister title Auto Express’ Driver Power owner-satisfaction survey, taking 21st place out of 26 brands, but the i8 takes much of its make-up from more conventional cars such as the 3 Series so, where possible, it uses tried-and-tested technology.

One thing that's worth noting is that due to its carbon-fibre passenger cell, if the car were to be involved in a big crash, this could write the vehicle off due to the fact this material is extremely difficult to repair.


Euro NCAP hasn’t crash-tested the BMW i8, but due to that strong carbon safety cell, the car should offer plenty of protection in a crash.

There are a lot of safety measures fitted to hopefully stop that happening. Stability control and anti-lock brakes are standard, while the £5,100 laser headlights improve visibility at night. They’re activated automatically.

The standard Driving Assistant package adds Approach Control Warning to help avoid collisions, high-beam assist, a rear-view camera and speed-limit info. There’s also pedestrian detection and, for £85, an eDrive sound emitter that warns pedestrians you’re approaching in towns and cities by emitting a noise.
