2017 BMW i3 : 33-kWh Battery For 114 Miles
2017 BMW i3 will come with a 33-kWh battery good for 114 miles of range. The new battery features cells with higher energy density, yielding a 33.0-kWh capacity, with the same external pack dimensions as the 22.0-kWh version. The new battery is heavier, though, and contributes to an overall weight increase of about 100 pounds, to 2961 pounds. It can bring energy consumption down to 27 kWh per 100 miles. The 170-hp synchronous AC motor powering the rear wheels, the i3’s performance remains “virtually unchanged.” That means zero to 60 mph will take just over seven seconds (eight seconds for the range-extender model), per BMW; our tests reveal that the i3 is quicker than that, with or without the range extender.
