Valtteri Bottas has called on Williams to return to winning ways after the famous British team lifted the lid on their 2016 challenger on Friday.
While Williams - winners of the Formula One constructors' championship on nine occasions - have enjoyed somewhat of a resurgence in recent seasons, they have not won a race in almost four years.
And it is nearly two decades since the Grove-based team won their last drivers' title following Jacques Villeneuve's triumph in 1997.
Bottas, who finished fifth in last season's standings, is optimistic heading into the new campaign which gets under way in Melbourne, Australia next month. The highly-rated Finn, 26, is keen to end the marque's winning drought.
"As a team we need to be able to win races, which is what we are always trying to do," Bottas, who himself is yet to take to the top step of the podium in Formula One, said.
"I'm sure we have made improvements everywhere as a team, so we're definitely looking to fight for better results this year.
"This is always a really interesting and exciting time of the year because we have a new car and we can't wait to get it out on track to see how it feels and how fast it is.
"It's been a good winter and from what I've seen we seem to be headed in a good direction with this car."
Bottas will team up with Brazilian Felipe Massa after Williams named an unchanged driver line-up for a third consecutive season.
Massa, who finished with 15 fewer points than Bottas last term, added: "Securing third in the constructors' championship for two consecutive years is a great achievement and one that comes with a lot of expectation - a momentum which I am excited to build on going into the new season.
"The team at the factory have worked really hard on the new car and we have spent a lot of time understanding where we need to improve.
"I have a lot of confidence in the team at Williams and I'm looking forward to getting behind the wheel of the FW38 to see how it performs.
"I'm equally delighted to be team-mates with Valtteri for another year. He is a very talented driver who brings a lot to the team."
The FW38 will get its first run out at the opening pre-season test in Barcelona which starts on Monday.
