Caterham has signed grand prix returnee Kamui Kobayashi and GP2 graduate Marcus Ericsson for the 2014 Formula 1 season.
The deal brings Kobayashi back into F1 after a season with Ferrari’s GT programme in the World Endurance Championship.
The 27-year-old Japanese driver had made his F1 debut as stand-in driver for Toyota in late 2009, before racing for Sauber from 2010-12.
