The Campos Meta F1 team has admitted that it may not take part in any pre-season testing, but insists it will make the opening race in Bahrain.
The Spanish team has signed Bruno Senna and its Dallara-built chassis passed the FIA's final crash test last week, but concerns remain about its financial strength and it is still searching for investors.
Campos's head of strategy Daniel Eisen says the season's first race will be the team's testing time.
"Bahrain is a test, it's not a first race for us," Eisen told the Associated Press. "The cars are very advanced, we have a driver under contract and our intention is to be in Bahrain for the first race.
"Everybody's worried and that's logical because the season is long and we're the new ones. But first things first, we want to be there with the best of everything - especially the cars.
"It's no secret that we are negotiating with investors and sponsors, especially on an international scale. But everything is going according to plan."
Eisen denied that the team's deal to run Bruno Senna brought in money and says Campos is determined to succeed without pay drivers.
"Bruno didn't come with cash, and that's important," he added. "We've always wanted it like that from the start. Yes, it would bring a lot economically, but our focus is to be ready. We can't compromise the cars in any way."
The team also admitted that it may not announce a second driver until the eve of the Bahrain race.
