As of 2014, however, Caterham has named Superformance their official distributor in the United States. International demand has increased dramatically in part due to the addition of a F1 Race team and the changes in Caterham's structure focusing on the distribution of the Seven worldwide. Caterham has since introduced a new model line up and focused on their production and production times to better suit their new international market, making their partnership with Superformance possible. Sevens will be shipped to the US in part-built form and sold as rolling chassis via Superformance's nationwide dealer network for customers to then complete the build personally or through the Superformance dealership. The initial US line-up includes several Caterham Sevens: 280, 360, 480, and the 620R.
