BMW i3 REx hits dead end.

There will be no range-extender offered for the 2019 BMW i3.

***UPDATE: We've received confirmation that the i3 REx will continue to be sold in the U.S., but not in Europe (WLTP cited as reason for cancellation).

It seems that the new 2019 BMW i3 with its 42.4 kWh battery (instead 33.2 kWh) has enough range not to bother with that emitting range-extender. BMW announced that it will cease production of the i3 Range Extender.

We assumed that the REx version would still be available because the i3 REx was still listed in the 2019 model year specification. However, BMW doesn't say anything about REx for the 2019 model year on its websites.

“The Range Extender i3 will cease production and we will only sell the pure-electric version going forward. With the gains in pure-electric range, together with the increasing availability of rapid charging facilities we believe the customer demand is shifting to an pure-electric model.”

It's possible that decision to kill the REx versions was made after the introduction of the 44.2 kWh battery, when the feedback encouraged BMW to go all-electric only. The decision may be WLTP based, too.

The range-extender option was one of the most expensive ones. A 650cc motorcycle engine combined with a generator provided 25 kW of power for about 100 km (62 miles) - limited by a very small tank capacity - of rather slow driving in the case of a discharged main battery (REx was turning on before the battery was fully depleted).

Sales data already shows that the 33.2 kWh was significantly more popular than the REx version anyways (it was 50/50 in case of 22 kWh battery).

So, say goodbye to the BMW i3 REx. It'll be a rarity in the future, so it's value may now increase in the used marketplace.
