F1's current world champion will not be running Renault
engines in its title defence, with the successful V8s set to be rebadged as Infinitis for the 2011 world championship campaign.
The powerplants themselves will not change, with the Infiniti logos appearing as a result of a marketing exercise that is expected to swell RBR's coffers by several million pounds as the units are now expected to be free. Infiniti is the luxury arm of the Nissan brand, with the Japanese marque now a sister company to Renault
after the two companies decided to work together in 1999.
The move looks set to be a good one for Infiniti, with Red Bull
already looking strong in pre-season testing and running an unchanged line-up of 2010 title contender Mark Webber
and eventual champion Sebastian Vettel. It is not a first venture into motorsport for the brand - which was heavily involved in the early years of the Indy Racing League in America - but the first time that it has moved onto the global platform provided by F1, coinciding with a recent broadening of its marketplace to include Europe and both the Far and Middle East.
Red Bull was the only title contender to pay for its engines, with Ferrari
both receiving theirs for free, so the potential £7m saving will no doubt come in handy for Christian Horner's team as it seeks to repeat its double triumph this season.
Official confirmation of the branding switch is expected at the Geneva Motor Show tomorrow [Tuesday].
