What is interesting is that, somehow the horsepower P85D achieves is unknown, even though it is known for the other cars. If it scores same as 85D, the achieved number for the original P85D would be 556 hp.
Nah, it is just marketing.
They could marketed P85D the same way as they marketed 85D - with max power output but then the people would go WTF? Both models have same max power, they must be the same cars, don't waste your money, it is a scam!!!!1111oneoneone
And all the work they did on improving maximum current to one motor and maximum torque at lower (and higher) end would go much wasted.
In the end the matters are stupidly simple. Each motor has its own limits, the battery has its own limits and the dynamic system of one battery, two controllers and two motors and one car as package has its own limits.
They beefed up front and rear motor/controller capabilities. The battery capability is above each of them by itself, but not above them combined. So they came out with 'clever marketing' of advertising (combined) motor power, that is pure sum motor/controller capabilities. Some incompetent dutch translators than went and translated that as 'max performance' or some such nonsense.
What could tesla do? Advertise P85D's 0-30 time and 70 - 100 time? With what would customers compare those numbers so they will see P85D as an awesome car? No other car company publishes those times.
What tesla could do and I would very much welcome such move is to publish what they already published for roadster - simple power/rpm chart.
But then again, 99% people would not have a clue what they are looking at. And would be totally confused by power starting at 0 at 0 rpm.
My point? There isn't one simple way of publishing the true technical specs and at the same time not shooting themselves into the foot by people totally misunderstanding those specs. People don't even understand there is no revving the engine at the start line in an EV.
