The Caterham CT01 made its first appearance at Jerez on Tuesday, with Heikki Kovalainen taking to the track at the start of testing. The car was the first to leave the pits when the track opened, completing a single installation lap before returning to the pits.
Kovalainen is scheduled to drive the car for the first two days, with recently signed reserve driver Giedo van der Garde and Jarno Trulli then getting a day of running each.
The CT01 features the "platypus" nose that most teams have opted for following the change in regulations lowering the height of the nose, as well as more compact packaging around the sidepods. It also features Red Bull's 2012-specification KERS unit, the first time that the team has used the system, and the reigning champion team's 2011 gearbox.
