The CT05 is first car to be fully designed and built at Caterham's Leafield Technical Centre and features a new all-green livery. For the fourth year in a row, the Caterham car is supplied with power from partner Renault Sport, now having a turbo charged 1.6l V6 in the back of the car, assisted with heat and kinetic energy recovery systems. Just as on CT04, the 2014 car has a gearbox supplied by Red Bull Technology.

The team was positive at the launch that its relocaton during 2012 to a location closer to other F1 teams helped to attract more experienced people that could drive the team forward. Additionally, the team made an agreement with TMG for the use of their windtunnel, enabling the team to start 60% scale windtunnel testing as of 30 January 2014. Upgraded CFD capacity was also installed to help develop the car, albeit that these agreements did not have any influence on the car ahead of its launch.

At the debut of the car, the team clearly aimed at an improvement in performance: ""In Renault Sport F1 and Red Bull Technology, we have technical partners that have powered the World Championship-winning team for the last four years and, while we are realistic enough to know we are very unlikely to be competing at the front of the grid, there is no reason why we should not be fighting higher than we have done since we came into the sport in 2010. We have extensive experience of working with both Renault and Red Bull, and that is going to be crucial this year. Reliability and energy management will play a key role in 2014, especially early in the season, so our experience of working so closely with both organisations since 2011 will definitely help throughout the course of the season."
