I put your numbers into my EV Designer and if you choose a 3:1 final drive, the results look quite good, about 160k/h top speed, 0-100k/h in about 4s
(I assumed the mid voltage motor with numbers extracted from emrax power/torque graph)
Are you sure your CDA will be 0,25? Tesla is very slippery and is 0.58?
Also CRR of 0.01 is lower than Tesla @ 0.014
Using the Tesla CRR,CDA as an example, assuming 2 Chevy Volt packs in series for about 630V, range would be about 150miles
Not sure this pack size is realistic with your gross weight of 500kg tho...
