RBR will be known as Infiniti Red Bull Racing from 2013 after agreeing title sponsorship with the Japanese manufacturer.
The deal, which runs until 2013, also includes technical co-operation in areas such as energy recovery.
Infiniti president Johan de Nysschen said: “While our first 24-months have been very beneficial to both parties, our new deeper relationship will bring increased advantages to Infiniti and Red Bull Racing. As title partner, Infiniti Red Bull Racing will help us garner even more worldwide exposure for our brand, products and technology.”
“Red Bull Racing and Infiniti have been working on a number of initiatives since the start of our relationship in March 2011,” said Christian Horner. “During that time, Infiniti has demonstrated significant technical prowess, and I’ve been impressed by the depth of the wider engineering capabilities of the Nissan Motor Company.
“In terms of marketing, Infiniti has leveraged their involvement with Red Bull Racing and Formula One very effectively and has become well known in a short space of time. These two attributes are what makes Infiniti the ideal title and technical partner for Red Bull Racing.”
Adrian Newey said: “Having a committed technical partner like Infiniti gives us a great platform for working together on technical projects, such as the Energy Recovery Systems for the 2014 season.”

Will de cars be know as Red Bull-Infiniti as well, i.e. in the shape of an engine badge deal? Or will ‘Infiniti Red Bull Racing’ have ‘Red Bull-Renault’ cars?
Maybe Infiniti makes better alternators?
Probably not, as Infiniti are just a brand-name of Nissan, who are part of the same company as Renault. I expect nothing will change mechanically
