WilliamsF1 has announced that it will unveil its FW34 shortly before the start of preseason testing at Jerez on Feb. 7.

The team will not hold a formal launch event, instead taking the wraps off the car in a pit lane photo call just before the winter running commences.

The FW34 is an important turning point for the team, which has slipped down the field in recent years. It is the first car produced with a large involvement from Williams' revamped technical lineup, and marks the reunion of the Williams-Renault chassis/engine combination. Williams won multiple titles with Renault during their previous association between 1989 and '97, and continued to run Renault-derived Supertec engines for a further two years.

Williams has retained Pastor Maldonado as one of its drivers for 2012, with Bruno Senna replacing Rubens Barrichello in the sister car.
