Ferrari president Sergio Marchionne is keen for the Italian manufacturer to push Mercedes further in Formula One this year, insisting more must be done to reclaim the Constructors Championship.
The Italian team last won the team title in 2008, with Kimi Raikkonen and Felipe Massa finishing second and third in the Drivers' Championship.
Ferrari have since undergone a seven-year drought, but picked up three race wins last season to improve upon a fourth-place finish in 2014 and come second to Mercedes - champions for a second successive year.
Marchionne felt their most recent display helped restore some of the credibility to Ferrari, but believes there is still plenty of work to be done if they are to avoid the possibility of a decade without a constructors' title.
"If we were to string together victories in F1 then it would improve our brand," Marchionne told La Gazetta dello Sport.
"I was speaking with one of our car dealerships, and we agreed that the results of 2015 helped bring back credibility to the brand.
"If we were to somehow fail to win a title over a 10-year span it would be a tragedy."
The Ferrari president credited last year's improvement to a change in investment strategy, though he was critical of the costs for participation in F1.
"We have continued to make investments that are in line with what we've always done. In 2015 we spent less than in the past, and by that I mean with respect to 2014," said Marchionne.
"We changed what we were investing in, developing what was needed and cutting down on the other things.
"We can still improve, but we can't quite say that the costs of Formula 1 are acceptable, as they are still huge."
