Proof that battery electric vehicle (or BEV), technology is constantly improving, the battery capacity in the BMW i3 is now double what the original model had when launched back in 2013. Starting life with 60Ah and a realistic range of approximately 70 miles, the 2018 model now possesses a 120Ah battery allowing for a real-world range of more than double that.

Battery upgrade for 2019 BMW i3

Despite being the same physical size, the official electric range now matches the 94Ah Range Extender Rex version, with 192 miles of range in WLTP testing.

This comes courtesy of a 42.2kWh battery which, according to BMW, allows both the i3 and i3 S to easily cover 160 miles during every day use. This equates to a 30% increase over the outgoing 94Ah model. Official WLTP figures state a 192-mile range for the i3, with the i3 S dipping to 177 miles.

This equates to a combined power consumption is 13.1kWh per 62 miles on the i3, while the i3 S has a power consumption of 14.6kWh.

Bye Bye Rex…

While there’s news of the larger capacity battery for the i3, it’s also worth noting the range-extender REx is no longer available. Now that the increased battery range is close to what the REx could offer, BMW sees little need for the added complexity of a two-cylinder internal combustion engine as a backup generator.

Minor updates to the range include a new exterior colour, adaptive LED headlights and optional wireless charging for compatible mobile devices.
