Williams has become the first team to uncover its 2016 F1 car, revealing pictures of the FW38 ahead of the opening pre-season test on Monday.
The Grove-based outfit’s 2016 machine sports a while livery with blue and red stripes of Martini for the third consecutive season.
Deputy team principal Claire Williams says the car shown in the photos is “far from the finished product”, with updates already being prepared for the season opener in Australia.
Felipe Massa and Valtteri Bottas have been retained by Williams and will drive the FW38, which will make its debut at the Circuit de Barcelona-Catalunya on Monday.
Winter running takes place from the 22-25 February and the 1-4 March in Spain. Williams has previously confirmed its driver schedule for the two tests.
"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 founder and team principal Sir Frank 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.”
