Interesting question. We don't technically know what the Taycan's official range is yet, so anything would be a guess at this point. I did some digging and found some info from Tesla on this.
Basically it looks like the AC impacts range by about 13 miles until you get over 100 degrees and then the impact is more severe.
Just be gad you don't have to deal with the cold... that's the real killer of range.
At 70 MPH in a Model S75:
With the A/C Off
Temp Range
70 241
90 244
110 253
With the A/C On:
Temp Range
70 228
90 230
110 216
