Although Pastor Maldonado is finding Williams' current form "frustrating", he insists the team will keep pushing while he tries to do his best.
Having secured his debut victory at last year's Spanish Grand Prix, the Venezuelan driver had hoped that would be a stepping to a better 2013 campaign. It was not.
Williams are in the midst of their worst season to date as they have scored just one point in 12 grands prix.
It has been a trying time for all concerned although Maldonado is adamant they won't throw in the towel.
"For sure it's frustrating," the 28-year-old told ESPNF1.
"To win a race last year - a couple of months ago - and this year to be fighting to even make it in to Q2 for sure is a big frustration.
"But we never back off, we are pushing very hard as a team, I am trying to do my best... but still we need to do some big changes in terms of performance in the car.
"Aero-wise we need to improve and soon we will improve with some new aero packages.
"We are still pushing with this year's car and maybe we can have maybe not the car to win all the races but have the car to put us in a good position to fight for points."
The Venezuelan driver is confident that Williams have what it takes to turn their fortunes around in time for next season.
"The only problem we have is maybe the most important which is the car, but if we work hard and put everything together I think we can solve the problems.
"We have a lot of experience, we have great people, a great factory as well. I think we have all the tools to make a strong car."
