We went to a wedding in Baltimore last night. Given the somewhat rough reputation of downtown Baltimore where our hotel was (I apologize for my prejudice as the environment turned out to be quite lovely), I planned for my wife and I to drive down from Princeton in her ICE BMW. However, a couple of hours before we were supposed to leave and my wife realized that we were not going to take the Taycan, she became very angry with my childish scratches&worse-phobia. She stated that it is just a car and that its silent gliding would make for a more comfortable journey down the highway than with her BMW. Knowing that any pushback from my side would have been futile, I rushed into my garage to try and top up the battery as much as possible before we had to leave. At the departure deadline, we left with an SoC of 95% and a guess-o-meter-projected a range of 329 miles in Range Mode and 326 miles in Normal mode. The extrapolated range in Range mode at 100% SoC would therefore have been 346 miles , or an extra 17 miles.
We drove to Baltimore yesterday Saturday and covered a distance of 148 miles and came back today Sunday, covering 151 miles (slightly different route), for a total trip distance of 299 miles (481 km). Upon our return, there were a projected 14 miles left in the battery. Since @epirali correctly suggested to use actual miles traveled as a better base to calculate real-life range purely on guess-o-meter extrapolations, I would state that the range with a fully charged battery under these conditions would be 330 miles (531 km) which is 14 miles left after the trip (projected) plus 299 miles driven (actual) plus 17 miles covering the 95%-to-100% SoC (projected).
Of the 299 miles driven, more than 275 were highway. The outside temperature on both days was around 30C/86F and the battery temperature hovered around 33C/91F most of the time. It was dry and there was no wind. On the highway, I kept the speed in the 75-80 mph band going to Baltimore and in the 70-75 mph band coming back. The A/C was in Eco mode and set to 19.5C/67F both ways with the front seats' ventilation being on at max capacity going and being off coming back. I forgot to check it yesterday but today's 151 miles journey back logged 26.3 kWh/100mi (16.3 kWh/100km) in the trip computer. Extrapolating that measurement, assuming that the useable battery capacity is 83.7 kWh, projects a total range of 318 miles (512 km) under these conditions, or slightly less than the 330 miles measured. This suggests again that the battery's real capacity may be slightly higher (86-87 kWh?) than 83.7 kWh.
