Williams has taken the covers off its FW38 challenger which will contest the 2016 Formula 1 season.
The latest design from the Grove squad features slight visible differences compared to its predecessor the FW37 with changes to the nose and sidepods.
Once again Williams will continue to carry the iconic Martini colours which debuted on the car in 2014.
After claiming third in the championship over the past two campaigns team founder Frank Williams expects a tough challenge to maintain its place in the pecking order this year.
The Mercedes powered FW38, which will be driven by Felipe Massa and Valtteri Bottas, will make its debut at next week’s pre-season test at Barcelona.
“Williams has started to cement our position back amongst the front running teams after finishing third in the championship in the past two seasons,” said Williams.
“This has been a great achievement given the resources of those around us. Staying where we are will be a challenge in itself, but we are determined to keep improving because only winning will ever be good enough.
“We have a very stable team going into 2016, with Felipe and Valtteri teaming up for a third successive season.
“They work well together and both have the ideal blend of speed and consistency.
“Our technical team has also remained very consistent which will be to our advantage and we have some of the best engineering minds on the grid at our disposal.
“We have a busy couple of weeks of testing coming up to learn more about our package and to refine the car ahead of the first race.
“We will have to wait until Melbourne to find out exactly where we stand in the pecking order but I’m confident that our hard work over the winter will stand us in good stead.”
After struggling for performance in slower speed corners last year, technical director Pat Symonds is confident the FW38 will address the issue.
“The FW37 was a pretty effective car and so we concentrated on understanding the areas where we could improve it without losing the attributes which made it effective,” said Symonds.
“It is no secret the low-speed performance of the FW37 didn’t match its high-speed performance, so a lot of time was spent looking into why this was and subsequently making changes, which we hope will improve the situation.”
