The Caterham CT05 is a Formula One racing car that competed in the 2014 Formula One Season. It was the last Caterham F1 car before the team folded prior to the start of the 2015 season.

The car was driven by debutant Marcus Ericsson and Kamui Kobayashi who returned to Formula One after a season driving in the FIA World Endurance Championship with AF Corse.{{cite web|url=https://www.autosport.com/f1/news/kamui-kobayashi-spurned-ferrari-for-2014-caterham-formula-1-seat-4471463/4471463/|title=Kamui Kobayashi spurned Ferrari for 2014 Caterham Formula 1 seat|publisher=Autosport|access-date=22 July 2022}}{{cite web|url=https://www.formula1.com/en/latest/headlines/2014/1/Kobayashi-and-Ericsson-to-race-for-Caterham-in-2014.html|title=Kobayashi and Ericsson to race for Caterham in 2014|publisher=F1|access-date=22 July 2022}} André Lotterer replaced Kobayashi for the Belgian Grand Prix, and Will Stevens replaced Ericsson for the Abu Dhabi Grand Prix.{{cite web|url=https://bleacherreport.com/articles/2182180-andre-lotterers-caterham-debut-shows-there-is-more-than-1-way-to-break-into-f1|title=Andre Lotterer's Caterham Debut Shows There Is More Than 1 Way to Break into F1

Drivers who were involved with CT05 either through practice runs or development included Robin Frijns, Alexander Rossi, Julian Leal, Rio Haryanto and Nathanaël Berthon.{{cite web|url=https://www.formula1.com/en/latest/headlines/2014/7/Caterham-launch-new-Development-Driver-Program-with-Berthon.html|title=Caterham launch new 'Development Driver Program' with Berthon|publisher=F1|access-date=22 July 2022}}

Development

=Design and technical=

File:Caterham CT05 nose.jpg

The CT05 was designed by Mark Smith, Lewis Butler and Hari Roberts at the new Leafield Technical Centre. The engine was the new Renault Energy F1-2014, and the gearbox from Red Bull Technology. Ahead of 2014, the team had struck an agreement with Toyota Motorsport to utilise their wind tunnel for testing and development, alongside upgraded CFD capacity at the new base.{{cite web|url=https://www.f1technical.net/f1db/cars/1015/caterham-ct05?sid=a25b96e4b307ea9f82e3e417a92ef5d1|title=Caterham CT05 Renault|publisher=F1 Technical|access-date=22 July 2022}}{{cite web|url=https://www.pitpass.com/50840/Caterham-CT05-unveiled|title=Caterham CT05 unveiled|date=28 January 2014 |publisher=PitPass|access-date=22 July 2022}}

=Launch and testing=

The CT05 was launched during pre-season testing in Jerez in late January, 2014. Marcus Ericsson drove the new car first on track. The car had a rear and wing design similar to Red Bull Racing and a unique nose cone. By August, the controversial nose design was adapted slightly to a more rounded design.{{cite web|url=https://www.motorsport.com/f1/news/caterham-reveal-the-ct05-with-an-interesting-nose/3219984/|title=Caterham Reveal the CT05 - With an Interesting Nose|publisher=Motorsport|access-date=22 July 2022}}{{cite web|url=https://www.f1technical.net/development/20881/caterham-debuts-new-nose-cone|title=Caterham debuts new nose cone|publisher=F1 Technical|access-date=22 July 2022}}

=Livery=

The CT05 featured a new livery design for the team, a bold metallic green set off with flashed of white, yellow and black. Airbus, GE and Dell Computers Intel took major sponsorship on the car.{{cite web|url=https://www.sportspromedia.com/news/caterham_renews_with_dell_intel_as_2014_drivers_confirmed/|title=Caterham renews with Dell/Intel as 2014 drivers confirmed|date=22 January 2014 |publisher=Sports Pro Media|access-date=22 July 2022}}{{cite web|url=https://www.motorsportweek.com/2020/02/04/ex-team-owner-fernandes-in-hot-water-over-airbus-sponsorship-of-caterham-f1-team/|title=Ex-team owner Fernandes in hot water over Airbus' sponsorship of Caterham F1 team|date=4 February 2020 |publisher=Motorsport Week|access-date=22 July 2022}} After the team missed two races due to funding, the final race of the season saw a car adorned with sponsors who had helped the CT05 reach the final race of the year.{{cite web|url=https://www.racecar-engineering.com/cars/caterham-ct04/|title=Caterham CT05|publisher=|access-date=22 July 2022}}{{cite web|url=https://www.racefans.net/2014/11/28/sponsor-watch-2014-abu-dhabi-grand-prix/|title=Sponsor Watch: 2014 Abu Dhabi Grand Prix|date=28 November 2014 |publisher=racefans.net|access-date=22 July 2022}}

Racing performance

The car performed poorly throughout the season. At the first Grand Prix of the year in Australia, both drivers retired. Indeed, the CT05 would chalk up 12 retirements in total, and three Grand Prix where neither car finished.{{cite web|url=https://www.statsf1.com/en/caterham-ct05.aspx|title=Caterham CT05|publisher=Stats F1|access-date=22 July 2022}}

The best result of the season was in Monaco, for Marcus Ericsson who finished in 11th place.{{cite web|url=https://www.formula1.com/en/results.html/2014/drivers/MARERI01/marcus-ericsson.html|title=Marcus Ericsson 2014 Stats|publisher=F1|access-date=22 July 2022}}

André Lotterer took over driving the CT05 at Belgium as Kobayashi, with no specific reason given.{{cite news|url=https://www.bbc.co.uk/sport/formula1/28869449|title=Belgian GP: Andre Lotterer in for Kamui Kobayashi at Caterham|work=BBC Sport |access-date=22 July 2022}} He would ultimately retire from the race. Kobayashi returned to the car, and in Singapore he failed to start the race as his brakes failed on the formation lap.{{cite web|url=https://www.planetf1.com/uncategorized/kobayashi-its-a-shame/|title=Kobayashi: It's a shame|date=22 September 2014 |publisher=PlanetF1|access-date=22 July 2022}}

Financial difficulties hit the team and they failed to field either CT05 at the United States or Brazilian Grand Prix.{{cite web|url=https://www.skysports.com/f1/news/17583/9532600/caterham-to-miss-us-and-brazilian-grand-prix-with-bernie-ecclestones-permission|title=Caterham can miss U.S. and Brazilian Grands Prix with Bernie Ecclestone's permission|publisher=Sky Sports|access-date=22 July 2022}} However, they returned for the final round in Abu Dhabi where Will Stevens drove in place of Ericsson before folding.{{cite web|url=https://www.eurosport.com/formula-1/caterham-f1-team-enter-administration-parts-put-up-for-sale-on-twitter_sto4450558/story.shtml|title=CATERHAM F1 TEAM ENTER ADMINISTRATION, PARTS PUT UP FOR SALE ON TWITTER|publisher=Eurosport|access-date=22 July 2022}}
