Red Bull has confirmed that its 2011 car, the RB7, will be revealed on 1 February.
The low-key unveiling will take place on the morning of the first day of pre-season group testing at Valencia's Ricardo Tormo circuit in Spain.
"Please note 1 February will be a normal test day," the championship winning team announced in an advisory to the press.
The RB7 will be among seven other 2011-specification cars to be running for the first time on 1 February, including the new Ferrari, Mercedes, Sauber, Renault, Toro Rosso, Williams and Lotus.
McLaren, Force India, Virgin and HRT will be testing at Valencia with their 2010 cars.
