I was there with my Zero, My Volt and my electric snowblower =) but the snowblower was just for the show and did not count for the guiness record.
We was 3 Zero:
my 2012 S
the Xu2011 of my friend Donald
The DS 2012 of another great guy
there was also 4 Sora electric motorcycle
I had chance to discus with their ingeneer and learned that they are using the Sevcon size 6 and 100V of EIG battery
This was amazing event!!
