Had an F30 330e myself until about 3 months back, great car, never gave any hassle but max range is about 23km on electric, not bad if your commute to work is within that; at one point I was about 5km each way so could get to work and back 2 days without charging.
Swapped for a G20 330e since then and Greta would be so proud of me
That's how much I have left in the tank since September when I picked up the car with a full tank from the dealer and the blue mileage is electric only.
