    In a cooperation between Lekker Energie (energy supplier) and DBM Energy (battery producer) a converted Audi A2 drove 605 km or 378 mi from Munich to Berlin without charging. They drove at night on freeways with a speed of max 130 KMH or 81 MPH and an average of 90 KMH or 56 MPH.

    The Audi was converted, but fully functional 4 seat car with all options of the ICE version.

    I can't read German, but that's pretty amazing. Were there special properties of the A2 that made this possible, or more related to the batteries used by the converter?

    This trip was made possible by Kolibri Technology developed by DMB Energy. The intelligent energy storage system based on Lithium polymer is substantially more powerful and lighter than other batteries.

    As to the forklift: I have no clue what kind of batteries are standard there, but the energydensity is not very good. A 24kWh battery weighs 715kg. (48V and 500 Ah, correct me if I am wrong).

    If you'd put a "Tesla" battery in a forklift, that would already make a huge difference, but would also increase the price of the forklift substantially.

    Not quite sure how they compare the two as there is very little information in their website.

    Ok ... impressive new technology. But factual errors too. They claim "Weltrekord" (world record) for distance. Baloney ! 323km=201miles. Tesla Roadster can do that in normal conditions with average drivers daily ! And beat that distance by more than 55% (313 miles not km); admittedly they did NOT do it in an "alltagstauglich" way (daily practical use).

    Reference: AussieRecord
     
  7. ChargeIT, your quote
    was just the stop over. They drove farther to Berlin a 605 km =~ 378 miles in total with 18% left in the batteries.

    Although, 90km/h is a bit low for German Autobahn (I guess that why the drove at night, otherwise even trucks would overrun that tiny little A2) the result ist quite impressive. They mention, they used 100kw/h battery... without compromising cargo space or seats.

    OOOOPS ! Sorry ! (Where's that red-face-embarrassed emoticon ?) Apparently their article is in dynamic update mode and I was not reading carefully. Apologies, again. :redface: (That should not be a upward-smiley on that poor excuse of a redface emoticon.)

    100kw/h is a large battery. Looks as if they could have gone ~ 90 additional miles, provided 18% is the actual remaining capacity. Anyone know what the approximate weight of a 100kw/h lithium polymer battery pack would be?

    Leaf ~25kWh ~600lbs. So 100kWh ~2400lbs. (Heavy!)

    I find it hard to believe the battery is 2400 lbs, as the car itself weighs 2233 lbs with a diesel engine. Better energy density?

    I think the battery can't have been that large if they've retained the four seats. An A2 is only 3.8x1.6m (12.5x5.5') so not much room for that battery but, what really impressed me is that they drove it normally, on the highway. The guys in AU were nearer 30mph in the Tesla.

    It isn't (2,400 lbs) ... Which is the impressive part of this supposedly "new" technology they are "celebrating". Very little technical details published at this point from what I can find.

    250 wh/kg! What's not impressive about that? Aren't the Panasonics being considered for the Model S 240 wh/kg?

    Sounds to me like a 100 kWh pack of these weighs a mere 400 kg 881.8 lbs. But then, I really suck at math so if anyone thinks my calculation is wrong, go ahead and break it to me gently.

    Since it's not a production vehicle it can make a lot of claims and many questions would be prudent. For example: does it still have airbags? Are they working? Would they (or the whole car) pass a crash test?

    Not like Tesla couldn't whip up something faster or run-farther if they wanted.

    This should be an interesting story. Waiting for more details and verification.

    It would be nice to have direct quotes from the creators and a picture of the pack at least (or specs of the cells).

    True, Tesla could easily build a 71kWh pack for the Roadster simply replacing the 2200mah cells with Panasonic 2900mah NCR18650 (232Wh/kg) which has been shipping for a while (don't know if the 245Wh/kg 3100mah NCR1650 cells are shipping in any significant volume yet, even though they have started production).

    I guess this record isn't as significant since it is not a production vehicle, but it could still shut up a lot of skeptics if even a prototype is made with almost 400mi range, running at highway speeds
