Ferrari removes ‘barcode’ from F1 car livery
The Italian team last week angrily rejected reports the signage was subliminal advertising for its tobacco sponsor Philip Morris.
Even Ferrari president Luca di Montezemolo slammed the suggestion, insisting the claims were "ridiculous".
But in the team's Barcelona pit garage on Thursday, the barcode was gone, replaced by a white rectangle with a red background.
However, the clothing worn by team members including drivers Fernando Alonso and Felipe Massa in Spain still features the barcode.
Scuderia Ferrari Marlboro said the decision to remove the signage from the livery of the F10 was made "together with Philip Morris International".
"This decision was taken in order to remove all speculation concerning the so-called 'barcode' which was never intended to be a reference to a tobacco brand," added the team.
