Williams aim to bounce back with FW29

The British squad finished in eighth place in last year's standings after scoring just 11 points and failing to reach the podium all year.

"Without question, 2006 was not our finest year but I am delighted to see how the entire Williams workforce has pulled together and redoubled its efforts over the winter," said team boss Frank Williams.

"It is how you perform in adversity that really counts.

"We begin this year with a completely new brand identity courtesy of our new partners AT&T, four new or upgraded sponsors including Lenovo, a wealth of new engineering talent and, of course, what we hope to be the focus of all these efforts and ambitions, the FW29."

The new car will be powered by a Toyota engine after Williams decided not to continue their relationship with engine suppliers Cosworth.

Technical director Sam Michael said the car is an evolution of last year's FW28 concept, with an aggressive aerodynamic package and a visibly radical front wing.

Michael said the car had already passed all the FIA's crash tests.

"The FW29 continues the design philosophy of the FW28 with a zero keel configuration," said Michael.

"The other notable elements of the design include another step in the undercut of the sidepod leading edge (with top louvres for cooling), improved engine and exhaust packaging to address the reliability issues experienced in 2006 and a lower and narrower top deck for improved aerodynamic efficiency.

"The other prominent differences from the FW28 include large chimneys expressly for cooling at the season's first three races and a narrower engine cover spine.

"At the rear of the car, a twin pillar configuration supports a lighter and lower drag rear wing, now featuring FIA-mandatory slot gap separators to prevent deflection and a lower and wider rear impact structure as required by regulation."

The team also announced a major new sponsorship agreement with Lenovo, a computer manufacturer, whose logos were very visible on the car.
