Ferrari have extended their sponsorship deal with tobacco giant Philip Morris to 2011 despite European Union legislation banning such advertising.
Ferrari are running with colour-only branding after recent legislation
Ferrari chairman Luca di Montezemolo gave no financial details when he announced the deal on Saturday.
Philip Morris' Marlboro brand is Ferrari's main sponsor, but the cars have competed without named branding since 31 July due to new legislation.
The directive banned all print and broadcasting advertising within the EU.
A Philip Morris International spokesman said the Marlboro brand would stay on the car in those countries, such as Malaysia and Bahrain, that still permitted tobacco advertising.
"It (the sponsorship) is going to comply with the rules and regulations wherever we do business," he said.
"There are countries where tobacco sponsorship is obviously not allowed. In those countries we will continue to support Ferrari without branding."
Di Giovanni would not comment on future commercial activities with the team, such as speculation that Marlboro could put Ferrari branding on cigarette packets as a way around the legislation.
Four of the 10 teams in F1 have tobacco sponsorship, with the others being Renault, Jordan and BAR, who are co-owned by tobacco giant BAT.
Tobacco companies in F1 believe that there may be promotional value even in running the cars unbranded.
The thinking is that simply having the colours of well-known brands like Marlboro on the cars may be enough to link the two in TV viewers' minds.
