BMW's i3 electric car is getting a bigger battery, 114-mile range

BMW's i3 electric car will have a little more juice for 2017, gaining a bigger battery to boost its electric range from 80 to 114 miles. It's all thanks to a 50 percent increase in battery capacity. Thanks to denser lithium ion batteries, the i3 goes from 22 kWh to 33 kWh without physically increasing the size of the battery pack.
