When we [Ars Technica] reviewed the BMW i3 back in 2014, the little rear-wheel drive city car left us quite impressed. However, the i3 has always had a couple of flaws in comparison with other electric vehicles out there; it costs too much and the range isn't very good, even if you go for the optional two-cylinder range-extending engine. It appears BMW has decided to address the latter issue, because from this summer the i3 will now come with a 33kWh battery in place of the current 22kWh unit.

[...] The new battery is 50 percent bigger, so more than 100 miles (160km) should be possible on a full charge. The gas tank for the range extender engine will also grow by 25 percent; expect to stop for gas every 75 miles if you try road-tripping. These range tweaks should help boost the i3's appeal, but before long the Bolt and Model 3 are going to make people expect 200+ miles from their EV as a bare minimum.

Happily for existing (and even potential) i3 owners, BMW says that current i3s can have the new battery retrofitted as part of a special program, although no one is saying anything about how much that might cost yet. Again, this kind of thinking is a promising sign for an industry that's never really considered upgrades as important. Tesla has excelled at pushing out new functionality to owners across the world on a regular basis, with both software upgrades and hardware retrofits, offering a better battery pack for Roadster owners in the past and underbody "armor" for the Model S fleet.

Tesla has shaken up the car industry with its award-winning electric vehicles (EVs) and supercharger network. Nearly every major brand now offers EVs or is seriously planning to offer them. A couple like Nissan and BMW have begun to build out their own charging networks. But this article highlights another way in which Tesla has re-invented the car: it gets better after you've bought it, through over-the-air software updates and battery retrofits that dramatically improve your EV's range. Will this upgradeability prove to be the "killer app" of the EV?
