Additional tests of a Volvo C40 Recharge, performed by Bjørn Nyland, reveal that the available battery capacity might be higher than initially anticipated.
During the near full discharge tests (from 100% to about 4% state-of-charge), the energy consumption reported by the car and the covered distance indicates that there is more than 75 kWh usable (out of the 78 kWh battery):
- at 90 km/h (56 mph): 75.8 kWh
- at 120 km/h (75 mph): 75.2 kWh
