Caterham’s Charles Pic and Giedo van der Garde have declared themselves happy with the 2013 car’s progress after the final test before the season opener in Melbourne.
While last year’s driver line-up of Heikki Kovalainen and Vitaly Petrov had seven years of Formula 1 experience between them, Pic and van der Garde have just one.
Caterham, meanwhile, have yet to score a point since joining the sport in 2010.
But last month team principal Cyril Abiteboul said he believed the fresh line-up would revitalise the team for their fourth season.
And after the last of three winter tests, both drivers said they felt they had settled into the team and are prepared for the new season.
Charles Pic said: “I’ve really enjoyed working with everyone – there’s a good atmosphere inside the team and we’re realistic about what we can achieve this year.
“We’ll go into the season with a good spirit and aim to take advantage of anything that comes our way when the races start.”
Giedo van der Garde added: “I’ve worked hard all winter to prepare for the season and today was a good test for how I feel physically and mentally, so it’s good to finish off the tests feeling prepared for the race season to start.”
During the last test in Barcelona, the team also announced American Alexander Rossi and China’s Ma Qing Hua as reserve drivers for 2013.
Both drivers will take part in a number of first free practice sessions during the season.
Rossi, 21, finished 11th in last year’s Formula Renault 3.5 championship and has been part of the team since 2011.
Ma, 25, who will also race for the outfit’s GP2 team this season, competed in four practice sessions with HRT last year.
“China can be proud that it continues to have a driver involved in motor racing at the very highest level,” said Ma.
