stolen from slashdot, which stole it from the comments in tfa: Translated from this page: http://adacemobility.wordpress.com/2010/10/26/das-wunder-von-berlin/#more-744 http://adacemobility.wordpress.com/2010/10/26/das-wunder-von... [wordpress.com] "Technical Data Audi A2 DBM * * Subject Empty weight (including driver) 1260 kg Perm. Total weight 1600 kg Battery lithium-iron-polymer (260 Ah/380 V) cell voltage of 3.8 volts Battery weight about 300 kg Charging time about 4 hours due to mains phase current in the household (380) battery requires 6 minutes (future solution) Life time 2500 charge cycles (without loss of capacity) = Service life target: 500,000 km Top speed 160 km / h 5-speed sequential gearbox (race gear: shifting without the clutch) E-motor 300 Nm torque" So, the 6 minute charge is future/theoretical limits of the battery. The actual time is 4 hours; which is still very impressive. Sincerely, Neil

That's a respectable amount of torque. My main concerns were power and range and they seem to have fixed a lot of these, I could see myself owning an electric car for my next.

(260 Ah/380 V) Please correct me if I've got the math wrong. I'm not really familiar with this area. 260 Ah/380 V = 98,800 Wh, or 98.8kWh Though I don't pay my own electricity bill, I looked the rate up for here in Halifax[1] and the rate is CAD$0.11796/kWh (flat rate). That means you could charge this for about CAD$11.83. Not too shabby. Also, if I'm reading this right, there is another option to pay based on time-of-day usage. The 11pm-7am option is CAD$0.06028/kWh[2], making the total roughly CAD$5.98 per charge.

  As soon as everybody would start driving EVs that price will not remain though, after all increasing demand would surely drive up the price.

    We currently have large excesses of power at nighttime, (production cannot be scaled down and back up in a 24hr period) so the effect could be mitigated by that.
