May 2 (GMM/ In between his Friday practice outings in Bahrain and Barcelona, Heikki Kovalainen has this week been back in action at the wheel of Caterham’s 2013 car.

In heavy rain, the Finn – newly signed up to a reserve and development role with Tony Fernandes’ struggling team – drove at Magny Cours for a ‘filming day’.

But Caterham may also have been testing new parts, as photos of the French test have revealed the CT03 with a new ‘vanity panel’ covering the usual stepped nose.

“We managed to get everything done,” former Caterham team racer Kovalainen said on Twitter.
