Nissan and Infiniti have reached a mutual agreement with the Red Bull Racing Formula One team to end the partnership between the brands.
The commercial partnership was originally intended to finish at the end of the 2016 racing season, but for unknown reasons it will end a year early, at the end of December.
It means Infiniti won't sponsor the cars, and Nissan won't provide light commercial vans to the race team anymore.
The partnership began in 2011, with Red Bull Racing winning four consecutive Formula One constructor and driver world championship titles between 2010 and 2013. Infiniti became the title sponsor of the team in 2013, and it was renamed to Infiniti Red Bull Racing.
Since then however the team have not won any championships, with 2014 and 2015 being particularly poor years. There's been no word on which company will next join with Red Bull.
Who do you think will sponsor the Red Bull Racing team next? Let us know in the comments...
