Caterham's CT05 2014 Formula 1 car makes belated track debut

The team had initially scheduled an unveiling in the pitlane prior to the start of the morning's running, but an issue with the car meant this was delayed.

It then took track to the track just before 3pm local time with rookie signing Marcus Ericsson at the wheel.

The new Renault-powered CT05 features an anteater version of the low nose that has become the focus of this year's F1 designs.

Caterham's version is one of the most extreme in the field, with its protruding section attached under a stepped upper element.

The Leafield-based outfit is heading into 2014 on the back of a disappointing '13 campaign where it finished 11th overall in the standings behind Marussia.

It has brought Kamui Kobayashi back to F1 to bolster its chances, as well as signing GP2 race winner Ericsson.

Caterham owner Tony Fernandes said last week that he wanted the team to become a more competitive force in 2014, otherwise he would turn his back on F1.

Team principal Cyril Abiteboul said such a strong stance from Fernandes was understandable.

"I think it is right," he said. "We should not lose sight that this is also a marketing activity and in order to promote the product we have to be successful and you have to be visible in order to attract sponsors. Right now we are not."
