P85D and P90D horsepower disagreement

[Kilowatt]

Still nothing from Tesla on pricing or availability. At least not in Sweden.

The 'motor power' is simply the max power the motor can make at a given system voltage (in this case the larger battery pack is the reference voltage level). The motor outputs max power when it hits 50% efficiency. Apply more power any all you get is more heat and less output.

The P85D and P90D do not have the same motor front and rear which means the power curves are very different. This is a good thing. Why would you want to align the power curve and stress the battery with a single huge peak in the power draw? The smart thing to do is to broaden the peak power by draw giving higher overall average acceleration and lower peak battery stress. This can be done by differing the motor wind or size or by differing the gearing F/R.

The reason Tesla has not been clear is because no other AWD car has two motors so it is not apples to apples. Tesla is going to be moving towards only stating 0-60 and 1/4 miles time as the car buying public is not up to speed yet. HP specs have always been exaggerated or spun anyways.

Are you saying that the P85D has a shifting bias between front and back depending on where in the power curve the two motors are? If so, please do tell more, if not, well then it is exactly like any other awd and indeed apples to apples.

Well if they only are going to use 0-60 times they better do it right, because at this moment no P85D is doing 0-60 in 3.1 s, so someone is not up to speed, then it is a Tesla P85D

The efficiency curve of AC induction motors is almost flat. You put 100KW into either of these motors and you will get nearly 134 hp at almost any RPM. The lower the RPM, the higher the torque but hp nearly the same.

My REST API readings are identical to the VBox calculated power output at the wheels minus about 9%.
