I've had a P3D- for two weeks. Love the car, but I'm running about 330 kWh/mile over the first 300 miles. It's mostly congested city driving, with some highway speed (65mph) driving at night. I traded in a M3 MR where my usage was 253 kWh/mile over the lifetime of the car (7000 miles) in similar driving conditions. I know that the P3D- is heavier and not as efficient as the MR, but my estimated range on the P3D- is about the same or a little less than the MR, despite having a larger battery. What kind of efficiency numbers are other P3D- drivers seeing?
