They are using AC Propulsion's AC-150 drive, which is up there in my list of dream drives. But at $25K, it is out of most people's price range.<br><a href="http://www.acpropulsion.com/technology/gen2.htm" target="_blank">

</a><br><br>As I mentioned before, Jeff Thomas of EV Bones is working on his personal kit car project and it is also using an AC-150 with A123 cells. He is using a Honda Si 5sp transmission with a custom 1st gear
set at 9.65 to 1 with all other gears removed.<br><br>- ian<br><br><div class="gmail_quote">On Dec 7, 2007 2:34 PM, Josh Handel <

So the Wrightspeed X1 prototype is the rich mans equivielent of what I
<br>was thinking of building. Its an Arial Atom (google it if you want to<br>learn about an insain low priced super car :-P).. Below are the X1's<br>specs.. Maybe its the newbe in me but I found them intresting.<br><br>
• 3-phase AC induction motor, 236hp at the motor shaft<br>• 182 ft lbs torque at the motor shaft, from 0 rpm to 6,000 rpm<br>• 13,300 rpm rev limit<br>• weight 1,536 lbs<br>• Energy consumption 200 WHr/mile in urban use, equivalent to 170 mpg
<br>(33,705 WHr/gallon)<br>• 25 kWhr Lithium Ion battery pack <--- I wonder if that is based on<br>traditional Amp hours or the .57 "1 hour" draw?<br><br>Of note, I found it intresting that they choose a fixie (fixed gear).
<br>That meshs up with other online comments about locking the<br>transmission in a single gear... Its also intresting to see what they<br>have done with mostly off the shelf parts (the Arial Atom chassie is<br>off the shelf, I am sure the motor and batteries are as well (although
<br>it may be a very hard shelf to "be allowed" to buy from :-P).. Also<br>intresting to see a consumption calculation on something that is in<br>the same spirit as my project :-)....<br><br>complete specs here:
