BMW i3 & i3s
Expect a big range bump.
About one year from now, in late 2018, BMW is expected to begin sales of i3 / i3s models with an upgraded battery and range, using all-new 120 Ah cells. The news was confirmed by BMWBlog sources.

"As we’ve reported before – and confirmed by new sources today – a new i3 with a 120Ah battery capacity will be out next year"
BMW introduced the i3 in late 2013, equipped with a 21.6 kWh battery (the capacity of lithium-ion battery cells was at 60 Ah). In 2016, BMW offered the 33.2 kWh battery (using the 94 Ah cells).
The new 120 Ah cells would store twice the energy of the 2013 BMW i3 - 43.2 kWh. All the numbers are total capacity (the usable amount is slightly lower).
With a 43.2 kWh battery pack, the i3 should be ready to go 150–155 miles (240-250 km) under the EPA cycle, compared to 114 miles (183 km) in the case of 33.2 kWh and 81 miles (130 km) for the 21.6 kWh battery.
