Mercedes reveals 2013 car launch date

Mercedes will unveil its 2013 Formula 1 car at Jerez on 4 February.

The launch of the W04 is taking place at the Spanish track the day before it hosts the first of the pre-season tests.

There will be huge interest in Mercedes' new car this season following the arrival of Lewis Hamilton to replace Michael Schumacher.

Mercedes took its first win in last year's Chinese Grand Prix, but subsequently tumbled down the order.

Shanghai victor Nico Rosberg stays on to partner Hamilton.
