"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. I also want to give special thanks to all the fans who have made donations to Kamui Support."
"Their donations and gestures gave me extra strength to come back fighting and I am very pleased that the money they raised not only helped me but will now go to helping Caterham progress this year. Every single one of you who helped with Kamui Support will race with me in 2014 and that makes me very proud."
"I first visited the factory in Leafield just before Christmas and it's clear how hungry the whole team is to make progress. Last year was a tough season, but the new rules this year mean that everyone in F1 is starting again and, that means everybody has a chance to improve. From what I've seen, Caterham now has everything in place to progress this year and for many seasons to come."
"We're all realistic about what we can actually achieve this year and until we've run the car properly at the tests it's still too early to see where we are compared to the other teams, but whatever happens we have to move forwards this year."
"For me, it's a chance to start again with a new team but one that's serious about progressing. For the team, 2014 is the first chance to show what they can do with all the people and infrastructure they've built up in Leafield since moving there in 2012."
"I can't wait to start work again. One of the benefits of making this announcement so close to the start of the tests means I only have a few days to wait to get back on track! Before then I'll be at the factory as much as possible, working in the simulator and with everyone there to prepare as much as we can for the tests in Jerez and Bahrain. Physically and mentally I'm fully prepared, now I just want to get back to work!"
Marcus Ericsson: "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."
"After a good break at home over Christmas, the hard work has already started. My physical fitness has always been good, but I've been working even more on that since the discussions with Caterham began."
"I'm going to be in the factory in Leafield as much as I can before and during the tests in Spain and Bahrain so I can play an active role in helping understand the 2014 car, and what we need to do to unlock its performance. We have a big task in front of us but it's an exciting one, and one both the team and I are ready for."
The Leafield-based oufit will launch its 2014 contender, the CT04 F1 car, on Tuesday January 28, the first day of pre-season testing in Jerez, Spain.
