i3, but like
@teslarati97 said, it was exposed to the elements. I attached a backpack cover to mine and it solved that issue. A third party company in Germany made a retrofit seal which is the more elegant solution. BMW left some space in the rear as well for BEV-only models. That same company made a new trunk insert to reclaim additional space.
No qualms with my American-made X3! I'm not big on frunks either, unless they are dead-easy to open like the F150 Lightening. Hard pressing the hood of an expensive Tesla or Porsche to close the frunk just seems wrong. F150 has a physical button right outside of the frunk. Also, it's huge and thus actually quite practical.
It's just an example of a small piece of space that could be re-purposed. An extra inch or two of interior space is actually significant.
Never drove a 4 series to compare it to a 3, but like the Taycan I was surprised by the interior dimensions of the i4 compared to the exterior. i4 seemed better though from that standpoint. Outside of the Mini I haven't found much to get excited about in the German EV space. Lucid/Rivian and even Ford seem to be killing it.
What's wrong with the Lucid Air in the winter?
