The RB9 is to be unveiled at the team's Milton Keynes factory two days ahead of the first four-day test in Jerez.
Technical director Adrian Newey had recently suggested the team's battle in claiming a hat-trick of championships at the end of last season had "compromised" the development of the new car.
At that stage there was a suggestion Red Bull would have to wait until the second test in Barcelona that starts on February 19.
But via their Twitter feed the team said: "The RB9 will be unveiled on Sunday 3 February in Milton Keynes ahead of the first test in Jerez. More details to follow."
