I was not able to find the information on the US website, but on the German one[0] you get: > BMW i5 eDrive40 Limousine: Stromverbrauch kombiniert in kWh/100 km: - (NEFZ) / 16,3 (WLTP); Elektrische Reichweite (WLTP) in km: 571 / Spitzenleistung: 250 kW (340 PS) So, your back of the envelope calculations are good! 16,3 kWh/100 km = 163Wh/km. Edit as comparison: Tesla Model 3, EPA calculations give 147 Wh/km. It is considered the most efficient car at the moment.
