Red Bull have announced an enhanced tie-up with Infiniti which will see the car firm become the team's title sponsor.
The Milton Keynes outfit first joined forces with the luxury car division of Nissan, which is part owned by the team's engine supplier Renault, on the eve of last season.
An enhanced agreement has now been announced until at least the end of the 2016 season to include both title sponsorship and "a number of new technology initiatives" - which Red Bull design chief Adrian Newey has confirmed will include work on the new Energy Recovery Systems for 2014.
From next season the triple World Champions will be officially known as 'Infiniti Red Bull Racing' and Team Principal Christian Horner says he has been impressed by the brand's capabilities to date.
"Red Bull Racing and Infiniti have been working on a number of initiatives since the start of our relationship in March 2011," Horner said in a statement.
"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."
Newey added: "Formula One presents immense design and engineering challenges on a daily basis. 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."
