Mind this van-like boxy design is a just an execution of "form follows function" principle.
The EV CFRP-based LifeDrive modular design, combined with functional cabin & trunk space gives you such a design, such a basic shape. It's an optimal shape for such a vehicle of such a size for such a purpose.
Sure there can be, and will be different variations of EV & hybrids within BMW i line-up. Eg. i8 is a proof shape can be completely different when different purpose of the vehicle is in question. And i8 design also follows form-folloes-function principle - as you can see the car is more starched than initial VED car (longer rear): all to improve & optimize the aerodynamics. Same case with large diameter yet narrower tires, special aero rims, (active) aerowings etc.
i3 will - when it's presented as a Concept later this year - prove to be an object of admiration. Just like i8 / VED has been. Yet i3 Concept will be closer to the production vehicle than VED Concept is!
i3 design & styling - just like the one of i8 - will be quite futuristic. It will be very close to the sketches published @ BMW i brand launch.
i3 is far from being "BMW's Multipla" - it will be instantly recognized as a BMW car yet within another dimension. With some line-specific design elements (blue kidney grille frame, BMW roundel within blue circle, specific front & rear lights graphics, typical i rocker panel, C-pillar with AirFlow element ... not to mention special BMW i color themes & combinations), EV specific architecture, futuristic appearance etc.
Why "BMW i" instead if "BMW isetta"?
Because BMW didn't want to introduce another retro (sub)brand to the automotive world. And there's already on in the BMw Group portfolio: its called MINI. And there will be EV MINI models as well. And mini MINIs etc. So - one retro EV line is enough, don't you think?
BMW i a step into the future, not into the past. Therfore futurism instead of retro. And BMW i is more appropriate marketing vessel for introducing different kinds & types of vehicles. Can you imagine a VED-based car being named eg. BMW isetta 1000? I don't. While within BMW i i3 & i8 can coexist without any doubt & problem. So can eg. i1 and i9.
Also: isetta wasn't a technological wonder in particular. Or a "vehicle of the future". It was a funny & funky car-like vehicle. Cheap, a provisional mobility solution for the masses at that particular time. Something BMW i3 is not. i8 even less. All what isetta has is the funkiness & instant recognition as microsized bubble car. Something project i cars are not.
Therefore decision for BMW i instead of (BMW) isetta, although isetta revival was seriously considered untiled ruled out due to not being a flexible enough platform for all the upcoming EV & hybrid cars BMW plan to offer. Creating a new sub-brand (a bit more distinctive Series) within BMW was a more logical & proper solution. BMW family brand helps to boost instant recognition & gives you a certain guarantee, while "i" sub-brand is there to differentiate, bringing something new, something different from regular, standard BMW cars. Just like the M sub-brand does: although not in design. i is therefore a stretch further, since there will be a significant different in design as well. Not to mention selling the cars under BMW family brand will boost BMW brand sales a bit. Not so if this was a separate brand like eg. MINI. It's also move how to prevent rivals to top BMW @ #1 place as best selling premium automotive brand.
Why "i"? Not because i is hip at this moment due to Apple products - being a synonym for user-friendly state-of-the-art technical innovation. But because "i" within BMW has a long tradition of being associated with BMW's own future, innovation, technology ... being that Neue Klasse cars (1500-2002 ti), fuel injected engines (2002tii, 318i), or the in-car-UI iDrive.
Sure decision for BMW i name sounds logical to BMW AG people, and some BMW aficionados but I guess BMW will have to communicate this decision to the general public a bit more, to inform the people why BMW i. It has a rational & emotional factor (so there are sound grounds for such a decision) yet they have to let people know about that.
