The e-tron 55 MY19/20 was originally shipped with 83.6 kWh available capacity. With a software update in 2021, these cars now have the same 86.5 kWh capacity as MY21+ cars. ABRP is apparently still using the old capacity for these model years, and I see no place to override the available net capacity (apart from choosing an incorrect model year). This makes ABRP a bit too pessimistic on range for these models.
