Video of the week: The BMW i8 production
The production i8 has a 7.1 kWh lithium-ion battery pack with a usable capacity of 5.2 kWh and intelligent energy management that delivers an all-electric range of 37 km (23 mi) under the NEDC cycle. Under the EPA cycle, the range in EV mode is 15 mi (24 km), with a gasoline consumption of 0.1 gallons per 100 mi, and as a result, EPA’s all-electric range is zero. The total range is 330 mi (530 km).
The production version has a fuel efficiency of 2.1 L/100 km (134.5 mpg-imp; 112.0 mpg-US) under the NEDC test with carbon emissions of 49 g/km. Under EPA cycle, the i8 combined fuel economy in EV mode was rated 76 equivalent (MPG-equivalent) (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent), with an energy consumption of 43 kW-hrs/100 mi and gasoline consumption of 0.1 gal-US/100 mi. The combined fuel economy when running only with gasoline is 28 mpg-US (8.4 L/100 km; 34 mpg-imp)
