Williams have begun preparations for the new Formula One season, unveiling their new FW34 car on Tuesday.
The British team have failed to keep up with the likes of Ferrari, Red Bull and Maclaren in recent years, but are hoping drivers Bruno Senna and Pastor Maldonado can turn that around this season.
Williams finished as low as ninth in last year's constructors' championship standings, picking up just five points, but team boss Frank Williams is hopeful the new drivers can gel quickly.
"One could say that looking at the Williams F1 Team today we are off to a truly fresh start," Williams said.
"We have a new car, new driver line up, new engine and new senior personnel. We also have a number of new partners who have joined the team in the past few months."
"I'd like to take this opportunity to welcome them formally and sincerely wish that they have an enjoyable and, most importantly, a valuable experience with us. The team has had a good winter at the factory and we feel ready and strong for the fight."
The new car features a number of modifications to the one that disappointed Williams fans last season.
They have replaced their Cosworth engine in favour of Renault - a name that aided the team's success in the '80s and '90s.
That period saw them win five Constructors' Championships, and Williams are now looking to emulate their past success.
"We’ve worked in close co-operation with all of our partners to achieve that, including Renault Sport F1," chief operations engineer Mark Gillan said.
"In the run-up to Australia, we will be working hard with our exciting new driver line-up to ensure that we maximise and unlock the full potential of the FW34."
"It is imperative that we demonstrate a continuous improvement in our performance and deliver results throughout the season."
The Formula One season begins on March 16 with the Australian Grand Prix in Melbourne.
