I can see, that if you look at the source code for the website above, the 2 numbers refer to the prices:

vehicle-model-code-71AW
BMW i4 eDRIVE40 Basis Drive

vehicle-model-price-71AW
65000.01 (this is German site, so I assume EUR 65.000)

vehicle-model-code-31AW
BMW i4 M50

vehicle-model-price-31AW
70000.01 (this is German site, so I assume EUR 70.000)

But these may just be placeholders.
Just for the comparison, the iX3 it starts at EUR 66.300,00
