Caterham unveiled its new Caterham CT03 in Jerez this morning, just minutes before the start of official testing.
The car is called 03 because 02 was allocated to a road car project.
The car has a new colourscheme with prominet branding for Renault, Airbus, GE and Giedo van der Garde’s sponsor, McGregor.
It has retained a prominent step on the nose, the team preferring not to go for a vanity panel.
