Well, those 200C cells would certainly allow a lower capacity pack,.... but i dont see a 5 kWh pack getting very far around that 8 min lap.
An 8 min. (approx) lap time using 5 kWh would dictate an average power of just 37 kW for a 220 km/h average speed ?? ..improbable !
Even 10 kWh pack would only give a 75 kW average power usage.
This is a 30+ km track (hills and long straghts) that is 80 % full throttle.
I suspect it will need more like the 200-300kW average power to get near that 8 min lap.
And that means a 30+ kWh pack
Since those 200C cells have a energy density of 142 Wh/kg,....that means at least 210 kg of CELLS.
TESLA cells are 240+ WH/KG, so their 100kWh pack has 400kg of CELLS
So yes, they could lose 200 ish kg off cells weight
.....but that is only enough for i lap....no warm up or sighting lap .!
