The AT&T Williams team's 2009 car, the Williams-Toyota FW31, will make its track debut on January 19, the Grove-based outfit announced today.
The test session will be conducted at the new 4.7 kilometre Algarve Motor Park circuit near Portimao in Portugal.
The car will run in its winter test livery, as its full racing colours will not be unveiled until prior to the Australian Grand Prix at the end of March.
Team attendees will be confirmed early next month.
