But EPA rating is a mix, not a freeway rating. Though fueleconomy.gov has specific numbers for freeway speeds as well.
My venerable 2017 S90D is listed with 294 miles range, that's 473 Km, or 19.8 KWh/100Km. My last trips to Italy used pretty much exactly 20KWh/100Km (2500-3000 Km each time, more than 90% highway at 120-150Km/h [sorry Italy]). In the city I'm usually below that on average.
