Range below 0%

Hello all,

My team will compete in a race in France at the end of the month. The key is to be the most efficient possible as we'll have to drive 8 hours with only 50 kWh.
As the 50 kWh will be base on the % shown on the dashboard, we would like to know if some of you tried to drive at 0%, and how many km/miles did you achieve in which conditions?

We'll get a 450+ for the race, but we won't be able to test it before.

Thanks!
