The Caterham F1 Team's CT03 race car for the F1 championship's 2013 season, was unveiled in the pitlane of the Circuito de Jerez, Spain, on day one of the first official 2013 pre-season test. The car was revealed by the team's race drivers Charles Pic, who will race in car #20, and Giedo van der Garde who will be in car #21 for the forthcoming season.
The 2013 car has technical features that distinguish it from its predecessor, CT01, and it will race in an updated livery for the season ahead. Some of the significant changes to the car are the trimmed down sidepods to improve airflow to the rear of the car. The diffuser, engine cover, and cooling exits have also seen major improvements. New front and rear wings and a new diffuser will be developed soon after the start of the season.
