This is a concept, so the production version will be a bit different, but overall the shape will be pretty much what we see here. They will of course lose the glass side panels and roof, both to be replaced with carbon fiber panels as is the entire outer shell. If you compare it to the renderings in the post below this, you see it is kind of a hybrid of a few of them. There haven't been much details released yet, but some of them of note that I did read are the car will have tall 19" wheels, which are very large diameter for a car of this size. The stated purpose for these are that they lower the rolling resistance and improve efficiency. It will also go 0-60 in under 8 seconds. It will charge on a regular household 110v outlet in six hours. That basically means the battery pack is small as previously reported, probably 16 to 18 kWh. It will also have a range extender option that BMW calls i-REx. The range extender will be a small gasoline(not diesel) engine that will only charge the battery pack, it will not have the ability to drive the wheels directly like the Chevy Volt can under certain circumstances.
I'm sure there will be lot's of info coming out in the next few days, I'll try to get it all up here as soon as it's available.

BMW Recruiting Engineers to Focus on Lightweight, Carbon-Fiber Composites
0 comments Posted by crue at 6:23 PM
According to this report BMW is recruiting 40 engineers that specialize in carbon fiber to join the i3 and i8 development teams.
The photo above is the frame of the i3 during crash testing simulations. This further proves BMW's commitment to the extensive use of CFRP in their future models, particularly vehicles in the new i line.
The i3 will eventually have three variations. The initial i3, the one we have been focusing on here will be a three door hatchback that seats four and is scheduled to be release in 2013. Rumors have it that this version will be then offered with an onboard range extending, gasoline powered generator. A few years later, there will be a smaller two seat hatchback with a smaller range for inner city driving, and then a five seat, four door version that is larger then the original i3 and will have a larger battery with a range at least as great as the original i3.
BMW may be joining the EV party a bit later than some competitors, but they certainly have some grand plans for the next three to five years. This recent news about hiring more engineers that specialize in CFRP only adds credibility to their commitment to light weight, highly efficient electric and plug in hybrid vehicles. That's good news in my book.

This move is a little surprising because in the past, BMW has rarely hired top people from other auto makers, electing instead to train and promote from within. In my opinion, this is an example of how important BMW feels it is to accelerate their electric car line and not fall behind in the race to bring a wide range of electric cars and plug in hybrids to their showrooms.
What I find particularly interesting is that there have been a lot of rumors around that BMW will be offering a range extender for the i3 shortly after the original BEV version is released in 2013. I'm hearing a lot of talk about a three cylinder, turbo charged engine as being the suspected powerplant for such a set up. This would make the i3 very similar to the Volt so in that regard Mr. Weber's experience can make an immediate impact on the development of the i3.
