It is way faster than the RWD model, just not from 0-60. After 60mph it is very close to the P model. It produces almost the same HP at higher speeds but less torque at lower speeds.Price to go to x-drive on the BMW is $2500 not $6,000.
x-drive offers no power increase just adds about 200 lbs of weight and more traction.
Tesla adds over 100 horsepower (I'd say very conservatively) and 200 lbs weight. It should be way more than .5 seconds faster in a spring than the RWD model.
I'd like to see some evidence that the P produces more power from the rear motor than the LR. It appears that it's only 50% more powerful than the LR. I see no reason not to believe that the 50% more power doesn't come ENTIRELY from the front motor. Why add a heavy front motor to the car and not use it?
