Vijay Mallya, however, said Sahara Force India was raring to go after a "satisfactory" pre-season testing stint.
"It's been a massive challenge, especially for a smaller team like ours. That was why we put so many plans in place early last year to be ready for what has become a very different Formula One. All the hard work has paid off but it has been a very steep learning curve and a huge undertaking to get where we are today," Vijay Mallya said ahead of the season opener Australian Grand Prix in Melbourne on March 16.
"It's the first time for many years that Formula One has been properly aligned with the automotive industry. The prospect of Formula One driving forward technical advances for road cars is a very exciting one," he said.
Asked about his team's final test in Bahrain, Vijay Mallya said, "It was certainly a good week in terms of mileage because we completed the second highest number of laps of all the teams. So we can be satisfied with the amount and quality of the work we were able to carry out. "We've learned a lot of things — by no means everything — and I think we can feel quietly confident."
Refusing to predict his team's chances in Melbourne, Vijay Mallya said, "It's never easy to make predictions and this year there are so many more unknowns than usual. I think we can arrive in Melbourne feeling happy about the work we've done over the winter. "How that will translate to a race weekend is hard to say.”
