Caterham signs Kobayashi and Ericsson for 2014
Kobayashi has been out of Formula One for a year after losing his Sauber drive at the end of 2012, but returns after a season racing Ferrari GT cars. Ericsson has been in the Formula One feeder series GP2 for four years and finished sixth in the standings last year with one victory.
"It's a great feeling to be back as an F1 race driver and I'm really pleased it's with Caterham F1 Team," Kobayashi said. "We've been talking to Cyril and Tony since last year about driving for the team for 2014 and beyond. Throughout all our discussions I've been very impressed with where they want to take the team and how much investment has been made already to help them achieve their goals.
"For me, it's a great honour that the team hired me based on the value I bring in racing terms and the experience I have. I am so happy that I am able to make this announcement today. I will do my very best to lead the team and work as hard as possible to achieve our targets."
Ericsson added: "This is a very proud day for me and everyone who has helped make my F1 dream come true. I'll be making the step up to F1 with Caterham F1 Team in 2014 and I'm already excited about the season ahead, and the first race in Australia in particular.
"It's obviously great for Sweden that we'll have a Swedish driver back on the grid in 2014. This is what I've been working for since I first started racing karts back when I was nine years old, and now I know I'm ready for the step up to F1. Caterham is a young team and together we can take on the challenges the new rules will present in 2014 - learning together and continuing to develop as the season progresses."
Alexander Rossi will remain as a reserve driver and will be joined by Robin Frijns.
