In a AWD Tesla Model 3, why is the front and back motor different?

In a AWD Tesla Model 3, why is the front motor (OEM 1120960-00-E) different from the one in the back (OEM 1120980)? Why not just use the same one for both front and back?

No idea, but if I had to guess probably different power levels and weight distribution.
