Without getting into the whole recyclable/sustainable issue, which as I said is due to German requirements, as I said above lightweighting is important, but let's look at exactly how much battery BMW saved through using CFRP, meanwhile achieving about the same range as the Nissan LEAF and most other sub-$35k BEVs - 2 kWh. Let's see, that $7k for 2kWh, or $3.5k/kWh. Since current pack prices are rumored to be in the $500/kWh range (certainly no more than $700/kWh), that's one hell of a markup even for BMW.
You're missing the point. The advantages come in many forms...it's a bigger car than a Spark EV, has more room, has more cargo space, is probably safer, has more utility, is as quick if not quicker, on and on and on..and has about the same range or perhaps even more than the Spark EV....and yet has a smaller battery pack and weighs less. That's the advantage. Yes it costs more...but if you want to make excuses about costing more...look at Tesla.
Let me correct you on one factual error, before replying to the meat: The Spark has a 21.4 kwH battery, of which 17.3 kWh is usable; the i3 has a 22 kWh battery, 18.8 kWh of which is usable.
The i3 is a somewhat larger car than the Spark, although considerably smaller than a LEAF (see the post by DeaneG for his impressions of i3 re the LEAF on this link: http://www.mynissanleaf.com/viewtopic.php?f=10&t=721&start=980 ) Depending on what you use it for that may or may not be important. 'Probably safer' remains to be seen. More utility? Spacewise maybe, if you have dogs not (no opening rear windows), rangewise probably only if you have the REx, because the Spark will likely go further on its battery. Again, Tesla being priced more buys you something, range.

Great, let's do that. Oh wait, we can't because BMW doesn't build such a car, although the lack of and desire for more range is the single biggest complaint/desire from customers (actual and potential), and is the primary reason why people bought about as many Teslas last year as they bought less than half as expensive LEAFs. We know batteries are heavy - we also know that it's batteries that provide range.
That's right...you can't compare the two because they are different cars at vastly different price points and used for vastly different types of use and driving. Again...the purchases of Teslas do nothing other than expose how many wealthy people there are. And the one and only reason why Tesla's sell well is because they've use the "range anxiety" marketing BS to work for them. They've oversized everything so people now think of the Tesla the same way you would think of a regular car...excess range...excess power. The fact that most Tesla drivers initially after purchase constantly charged their cars...only to stop charging constantly after a few weeks of ownership...is testimony to the psychology at work rather than the reality. So they are able to sell EV's with huge battery packs to people who probably won't drive more than 30-40 miles a day anyway in and around San Jose, etc.
If you live in the bay area, a simple trip from San Jose to San Francisco for dinner, theater or what have you, is about 100 miles round trip, almost all freeway. Commuting in from the central valley, as many people do (the Bay Area is the supercommuter capital of the country), you're looking at 100-180 miles round trip; crazy, but people do it. And if you go out of town on the weekend, you're looking at 100 miles or more one way. So unless you think that the average Tesla owner is a retiree who only motors around at 10-15 mph inside a gated community, your 30-40 miles per day is ridiculous. Sure, that's enough for many people's commutes, but it's certainly not enough if you want to use it for anything more. Which is kind of the point, because if you don't need more range, why on earth would you buy a Tesla in the first place?

It's certainly big and heavy, but then given current batteries if you want range you've got no choice but to do that. The pack of an S85 weighs over 1,300 lb, and uses batteries with a higher specific energy and energy density than BMW uses. If we were to assume that BMW would build a 5/7 series to compete with it, then by using CFRP they might save 8kWh of battery, assuming the same ratio as applies with the LEAF/i3 (and the LEAF is steel not Al, so the weight saving will be less over the Tesla). But I'd love to see them build such a car, and see how they price it, cause at the moment Tesla has absolutely no competition as a long range BEV. I don't slobber over them, it's just a car, but that's the fact.
Again, I don't really care what Tesla does....we're talking about AFFORDABLE EV's in the price range of the majority of people who would like one or are considering one. It's great Tesla has given wealthy people options to buy a long range EV....doesn't help me or 99% of everyone else out there. In the same token that you say let's wait and see how much BMW's 5/7 series EV's will be, let's wait and see how cheaply Tesla can make a $30K EV and what sort of range, performance, and options it will have. Hopefully they'll do it soon...but I doubt it. They are still too busy catering to Elon's rich buddies.
If you don't care about Tesla, then why did you bring them up? I was just replying to your statements, especially the one where you swapped cause and effect of why the Tesla S is big and heavy. As to the Model E, that's due in the 2017-2018 time frame, for somewhere in the $35-$40k range, and with about 200 miles of range. We'll see how well they meet that - I suspect it will depend on how well the Model X does.

Ah, but it's BMW's decision on U.S. pricing that we're talking about. In Europe it's priced far more competitively. And up until the most recent generation, BMW's higher price did buy you something in terms of performance, handling, and driving qualities; that particular laurel has been looking a bit shopworn recently.
It's really moot at this point to call out BMW's pricing as competitive or not in the US as official leasing/financing options have not been released as far as I know. So let's wait and see.
Well, we did have an electronaut ask his dealer for a lease quote, and that's where the $800/$900/month figure that others have quoted came from. See http://insideevs.com/heres-a-look-at-a-bmw-i3-lease-quote-of-930-per-month/
Since that went over like the proverbial lead balloon, BMW will have to offer leases well below those prices.

22 kWh; 18.8 kWh is usable. Now compare it to the Spark EV's stats. The Spark is built of steel and is a couple of hundred lb. heavier, uses a battery chemistry of lower specific energy and energy density but better durability, has about the same or better EPA range and may well go further in real life, and costs $15k less. The i3 is a nicer car in most areas (suicide doors with non-opening rear windows and a stupidly positioned charge port aside), but it's not $15k nicer.
Well to you it may not be $15K nicer but then again someone buying a Kia Optima turbo might say the same thing about a BMW 328i or MB C250 too. EV's are no different. The price staggering will be the same for EV's as it is for the IC equivalents...so this sudden "under the microscope" attitude for EV's makes no sense whatsoever. It is what it is..like it or leave it. Just like I choose to "leave" the Tesla.
Sure, value is in the eyes of the beholder. It just happens that lots of EV enthusiasts, including a considerable number of 'Electronauts', don't see it in the i3, any more than they see the value of a tarted-up $75k Volt. And at least for myself, there's nothing sudden about an 'under the microscope' attitude towards EVs. I apply the same criteria to them as I do for any other car, or any other expensive technology.

If money isn't an issue for you, go for it. For me, I can't see paying premium prices for a utilitarian car.
I'll let you know if money is an issue once official buying/leasing options are available. Until then, I'm focusing on the innovation incorporated in the vehicle which will, undoubtedly, trickle into other cars across the automotive technology fields for all manufacturers. I'm not a BMW lover but I do applaud BMW for taking the chance and investment in using such new technology on their new vehicles. It shows forward thinking.
Well, sure, it shows forward thinking. They either get better gas mileage and reduce emissions, or they'll have to reduce the # of cars they can sell in California, and we constitute about 10% of the U.S. car market and probably a much higher % of the U.S. BMW market. So far at least, CARB seems to be sticking to its guns, so BMW either makes their cars lighter, sells more diesels if CARB will let them, or employs lots of other expensive technologies to boost mpg and meet CAFE. And we already know what the car's MSRP is, and today we know that you won't be able to buy one for three months without including every single option except wheels (unless you're an 'electronaut').
