Red Bull will reveal its 2012 car during an internet presentation on the day before the RB8 is given its official track debut.
The reigning champions said in a media statement that the Adrian Newey-inked car will be seen for the first time on the team's website on 6 February, the day before the opening four-day test at Jerez kicks off.
Red Bull said the car will be seen "in a different light" at 1pm.
Meanwhile, F1's sixth-ranked team in 2011, Force India, will reveal its new car on February 3 at 9am at the Silverstone track, located across the road from its Northamptonshire headquarters. Technical director Andrew Green said the VJM05, whose monocoque has already passed the FIA's mandatory crash tests, will be built and fired up next week.
"There's always a buzz around when it's happening," he said.
