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," Mallya said ahead of the season opener Australian Grand Prix in Melbourne on March 16.
Asked about his team's final test in Bahrain, 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."
"How that will translate to a race weekend is hard to say, but I think it's important that an element of unpredictability has returned. There is plenty of interest around Formula One at the moment and that's a good thing."
Sahara Force India driver Nico Hulkenberg said he was satisfied with the pre-season testing.
