Why is the BMW i8's fuel efficiency higher in city driving than on the highway?

I've noticed that my BMW i8 seems to get much better fuel efficiency in stop-and-go city driving compared to highway driving. Why is this the case and what can I do to improve my highway fuel efficiency?

Hi Sarah, this is a common question amongst BMW i8 owners. The reason for the difference in fuel efficiency is due to the regenerative braking system in the i8. This system captures energy from braking and converts it into electricity, which can be used to power the car's electric motor. In city driving, there is more frequent braking and therefore more opportunities for the regenerative braking system to recharge the battery. On the other hand, on the highway, there is less braking and more constant driving, which uses more gasoline. To improve your highway fuel efficiency, I recommend utilizing the i8's ECO PRO mode and driving at a consistent speed. This will help optimize your fuel efficiency.

Hi Sarah, I have noticed the same trend with my i8. What I have found to be most effective in improving highway fuel efficiency is using the car's hybrid mode. This mode allows the car to use both its electric motor and gasoline engine, providing a more efficient balance during highway driving. I also recommend keeping your tires properly inflated and avoiding aggressive acceleration and braking. This will help improve overall fuel efficiency.
