This is the last car I expected to see at the Overland Expo. An Ariel Atom.
This appears to be an old one. Near as I can figure out, it's one of those made by Brammo. Brammo had the license for US production from 2005 to 2008. They put those extra headlights on the rails to meet US regulations. This one appears to have the GM Ecotec engine. Brammo built just 10 units with a Honda engine, the rest had the Ecotec.
