Williams unveil 2008 colour scheme

The Grove-based squad used six different liveries during winter testing to commemorate a sequence of landmarks that will take place during the year.

Their final colours of the Toyota-powered FW30, however, were only unveiled today, less than two weeks before the start of the season in Australia.

Williams have impressed during winter testing with their new car, and team co-owner Patrick Head admitted they are hoping to give Ferrari and McLaren a scare in some races.

"We don't really target any particular team. We are just trying to do the best we can. Ferrari won the championship last year so they are the target," said Head.

"Obviously I would be disappointed if we cannot get in and give the odd Ferrari and the odd McLaren a fright during the year. But both of the teams seem to be in very good shape for the start of the year.

"BMW, I think, have had a difficult introduction but they seem to have got it pretty well sorted now and I think they will be quick.

"Red Bull seems quite good, but they have been stuck in the garage a few times. Renault have made some positive noises and I am sure they will be better than last year but you don't get the impression they will be challenging Ferrari and McLaren."

Head reckons that it is very hard to predict the current pecking order behind Ferrari and McLaren, although he is convinced Williams have taken a good step forward from last season.

"It is very difficult to judge exactly where we are because a few of the cars have done good runs," he explained. "A lot of people were saying that Toyota were right out of it and Ferrari were miles quicker, but the 1m20.8s that Jarno (Trulli) did at Barcelona is a pretty quick time.

"So I don't think we really know where we are really going to line up and that will only become clear when we get to Malaysia."

He added: "We know we've got a much better car than last year's car and a much more stable back end on it and things. But I think quite a number of teams have got improved cars."
