I watched the entire X-Prize contest on a recent flight. Seems like the Tango
Commuter Cars - The Tango, ultra-narrow electric car for commuting; 0-60 in 4 seconds
Outperformed most of the field, except for not making the 100 miles range. But to be fair, the tango could out accelerated most cars on the road.
I'm sure they could produce a FE model of the Tango that would win every catagory in the X prize contest.
Amazingly the Tango did not have a pit crew, just the owner/inventor one man show. Other teams spent millions, and hired professional drivers for the contest.
