I have a LR RWD purchased in June 2019. I have 1622 miles on it so far. My efficiency is 257 Wh/mile. I charge my car almost exclusively at work and can see that I have used approx 600 Kwh to date for charging. Per my calculation, I should have only used 1622 x .257 = 416 Kwh so far. Where did the other 184 Kwh go? Phantom drain? Thank you!
