While cars like this offer emissions-free motoring in full electric form, they often consume a lot of energy and resources during the production process. But BMW's i3 line at the Leipzig, Germany plant is actually powered entirely by four giant wind turbines. 80 per cent of the vehicle's aluminium is either recycled or produced using renewable energy. It's pretty impressive stuff.
The battery system is made up of 96 cells, which remains unchanged for 94Ah models. BMW has been able to add extra electrolytes and increase cell density to offer greater battery capacity. Similar to Tesla's offering, the entire battery system comes with an eight-year/100,000km warranty.
Charging times have increased as a result of greater battery capacity. Using the occasional-use cable supplied with the car, charging occurs at 8A at a rate of 1.8kW, taking 14 hours to charge from empty to 80 per cent (the usable maximum). That charge time decreases to eight hours when using the BMW i Wallbox, which runs on a 16A circuit at a rate of 3.7kW. Owners can also use ChargePoint locations free of charge that reduce charging times to four hours at a rate of 7.4kW at 32A.
