Good questions, JayBee. Yes, the three-hour recharge time is for a residential location operating at 30A and 240V. The i3's battery is is not terribly big -- about 21 kWh, which makes it larger than the Volt's 16-kWh battery butsmaller than the Leaf's 24-kWh battery. It's also significantly smaller than the BMW ActiveE (an electric demonstration car from BMW) battery, which was 32-kWh. Regarding the DC fast charge: This is the SAE DC fast charge methodology. BMW is officially saying that the DC fast charge would be one hour, but I think they're being conservative. It's probably closer to 30 minutes. But that's a 480V, three-phase power, which homes typically don't have. Sorry we didn't mention this in the article.

BMW is saying that this isn't a so-called "compliance car," Cadman-LT. All automakers say that, of course, but I tend to believe it in this case. We'll know better when the i3 hits the road late next year, though.

Yes, BMW built it and showed it off at the recent LA Auto Show, akwaman. But this coupe is not as far along as the i3 five-door, which is the one that will come out in 2013. As to whether they will make their 2013 production schedule...I think they will. We've been talking to them about the i3 and i8 since 2011 and they haven't wavered from that schedule.

The drive module absorbs the impact via deformation.

The life module says the deformation stops here.

To stop deformation, the remaining G-forces must be absorbed.

Hopefully, in this division, there is no remainder.

Prius, Tessla, BMW.  Who's next? Aston-Martin? Yes.

Although we're unlikely to see a Rolls Royce Phantom charging up anywhere soon...

...it still begs the question; What will be the car to be seen in by Hollywood's most environmentally concsious?

The i8 is the car on the right in the main photo, not left, which is the i3.

Charles,

Nice article. I think those are Maclaren-style doors. I always liked those. Spectators are busy checking out the doors and maybe won't notice you gracelessly struggling to climb out of the deep bucket seats. The i8 concept looks cool. Kinda looks like a cross between a 6-Series and a Genesis Coupe. Too bad the price will be high. Decent charge-time, good styling, but the range is a bit limited for highway trips even with the range extender. I guess time will tell.

Cheers!

Good point about the struggle to get out of the car, NiteOwl. The doors do look great, though, don't they?

Charles,


Yes, I hope those doors make it into the production version. I think it's safe to say this isn't just a compliance car. Looks like they put a lot of work into it and it brings quite a bit of inovation to an industry sorely needing it. I hope there's a market for the car. At the very least, this design should influence other brands.


Cheers!
