I call bullshit on this. 1000km range and 400km/h top speed?
Obviously you can't have both but each of this is unrealistic enough on its own.
You can't even go 400km/h on the Autobahn, which roads are they building this for?
And fully loaded SUVs like the Hyundai Kona get somewhat about 500km in normal crusing mode. 1000km is either a breakthrough in battery technology or measured/calculated when going 50km/h at best.
Unrealistic values imho, but I'm open to be proven otherwise.

They're competing against ferrari/lamborghini/mclaren. The top speed is for the track, not the street. That should be quite obvious....

The range is clearly not based on going the top speed for the duration. The distance Tesla gives is typically based on a combined city/highway driving profile. They also provide calculators to estimate your range bssed on the mixture as well as a map program that tells you where you'd need to charge getting from point A to point B if you're going on a long-distance trip.
Speed / power is a similar affair; a bigger battery is essentially more battery cells, and more power. The increased weight doesn't significantly detract from top speed, as air resistance dominates. In fact, additional weight increases down-force on the road, and thus the maximum force the wheels can apply.
Not if you’re battery-limited in performance. An ideal performance electric car is all battery and motor with the weight of everything else reduced as much as possible. That naturally means your battery will be way over-sized compared to a typical electric car.
Electric batteries are power-limited as well as energy-limited. So if you want more power, you need a bigger battery. (Alternate chemistries are also possible, but even then you reach a practical limit.)
The naive approach is to think of a battery like a gasoline tank, whose size and capacity you want to minimize if you’re going for performance records. But really it’s part of of the powertrain, and having a larger battery brings a bunch of other benefits like longer lifetime (in miles driven), charge & discharge speed (in kilowatts), higher thermal mass (can handle those big spurts of power that might temporarily exceed the cooling system’s capacity), and higher electrical efficiency at a given discharge speed (a larger battery at a given voltage has lower internal resistance, thus less resistive losses and less heat generation).
