Williams won’t debut its new car, the FW35, until the second pre-season test, the team confirmed on Friday.
The team will be present at the first test which kicks off at Jerez on February 5th, but they will run their 2012 car in 2013 livery whilst testing new parts.
The launch of the FW35 will take place at the Circuit de Catalunya in Barcelona on February 19th, the first day of the second test.
Valtteri Bottas and Pastor Maldonado will drive for the team this year.
