Red Bull has confirmed that it has split with Infiniti, following the change to its Renault deal for the 2016 season.
Red Bull's Renault engines will be branded under the Tag Heuer guise following its souring relationship with the French manufacturer and, consequently, its title sponsor Infiniti will depart.
Infiniti joined Red Bull in 2011 and became its title sponsor ahead of the 2013 campaign, with the change reflected by an increase in purple on the outfit's livery.
"We would like to say a big thank you to Infiniti for their contribution to the team since they joined us as a commercial partner in 2011," said team boss Christian Horner.
"They became the title sponsor of the team in 2013 where Infiniti enjoyed greater visibility than any other manufacturer in the sport.
"We wish them all the best with their plans for the future."
