Frank Williams says FW34 represents a 'truly fresh start' for his team

The team unveiled its car - the first to be produced since a major shake-up of its technical staff - in the Jerez pit lane shortly before the start of the first day of pre-season testing.

With co-founder Patrick Head and technical director Sam Michael departing, and Mike Coughlan taking over the technical side of the operation, Williams says the team's new car signified the new shape of his squad.

"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."

Mark Gillan, Williams's chief operations officer, said that continuous development of the car will be crucial for the team.

"It is imperative that we demonstrate a continuous improvement in our performance and deliver results throughout the season," Gillan declared.

"The factory has worked extremely hard over the winter to ensure that the car met its design, build and rig test targets.

"We will be working hard with our three exciting young drivers to ensure that we maximise and unlock the full potential of the FW34."
