Brammo Motorsports of Ashland, Oregon signed a deal with Ariel Ltd to manufacture the Atom in the US starting in late 2005. In the US the Atom 2 was available with the supercharged GM Ecotec engine, which was introduced in 2004 on the Saturn ION Red Line and is also used in the Chevrolet Cobalt SS. A limited run of approximately 10 US built Atom 2 cars, manufactured in 2006-2007, were powered by imported Honda K20As. Brammo Motorsports ceased production of the Atom in 2008 to focus on the manufacture of an electric motorcycle.
