After seeing the video and seeing the prototype move and the figures given for it. I don't understand how this car is capable of the speeds and range that it is said to have. 200KWH & a top speed of at least 400km/h potentially indicating over 800 to 1000 horsepower. From what I know for the P100D 568KW is pushing the limits of the battery pack to point of potentially damaging it.
From what I understand the battery packs are also rather large and very heavy, rough numbers below.
265 wh per Kg Li-ion
200000 / 265 = 755kg lowest according to wiki
100000 / 265 = 377kg is actually 500kg according to the forum
So my question is how does the Roadster move as fast as it is said to move. While not being over burdened by a huge and heavy lithium ion battery weighting as much as a car itself?
Does that car have some special battery in it?
