Why is the BMW i8 hybrid's gas mileage lower than other hybrid cars?

I've noticed that the BMW i8 hybrid gets lower gas mileage than other hybrid cars on the market. What is the reason for this and is there anything I can do to improve it?

The reason for the BMW i8's lower gas mileage may be due to its larger and more powerful engine, which requires more fuel to run. To improve the gas mileage, try using the car's eco mode and avoid using the sport mode too often.

Another factor that can contribute to lower gas mileage is the weight of the car. The i8's sleek and sporty design may make it heavier, resulting in reduced efficiency. To help with this, make sure to empty out any unnecessary items from the car and try to reduce its overall weight.

In addition, the i8's hybrid system may not be as advanced as other hybrid cars on the market. This could also lead to lower gas mileage. However, one way to improve this is to regularly maintain and service the hybrid system to ensure it is running at its best.
