Horner future set to be in the balance at Red Bull
However, Van der Garde, who raced for Caterham during the 2013 season admits he would be shocked if Horner was still in charge by the time the constructors' champions' reveal their latest design.
Speaking on his podcast, DRS: De Race Show, Van der Garde cast a firm verdict on how the hearing would go for Horner who has been in charge at Red Bull Racing since their 2005 inception.
He said: "Horner is of course controlled internally by Red Bull. Believe me, when that presentation comes next week, Horner will definitely not be there presenting."
"This is of course dramatic for Red Bull and they will also have those presentations next week. Red Bull will once again come with a very good car, so in that respect they will have a very good season, but this is a bit of a blemish on the name, and also the team."
