The Standard is the base version of the Atom 3 introduced by Ariel in 2007. This high performance, rear wheel drive, open top car features an exposed chassis and is fitted with minimal body work. It marked a significant step forward in the evolution of the Atom, cementing its status as one of the most extreme and lightest sports cars on the market. It was the first generation to be widely distributed in North America. With a manual transmission and a 2.0L or 2.4L inline four engine, the Atom 3 was produced until 2014 when it was updated to the Atom 3.5 version.
