Red Bull moving on without title sponsor

London, England - Red Bull looks to be moving on in Formula 1 without a title sponsor.

In December 2015, following the marketing split from Renault and the rebranding of Red Bull's engines for 2016 as Tag-Heuer, the team admitted it will no longer be backed by Infiniti.

It is the luxury road car division of Nissan, which is owned by Renault.

'We wish them all the best'

Team boss Christian Horner said: "They became the title sponsor of the team in 2013 when Infiniti enjoyed greater visibility than any other manufacturer in the sport.

"We wish them all the best with their plans for the future."

So on Monday (January 4), Red Bull Racing revealed its new logo for 2016, confirming not only the departure of Infiniti but that a replacement title sponsor has apparently not been signed.

The logo reads simply: "Red Bull Racing Formula 1 team".

Red Bull still a force

Horner has said 2016 will be a year of transition for Red Bull as it prepares for the radical new engine and chassis rules of 2017 and beyond.

But Mercedes' Nico Rosberg says the former quadruple world champions should never be ruled out.

He told Germany's motorsport-magazin.com: "You always have to reckon with Red Bull. They are a very strong team.  Up to one and a half years ago, they were absolutely dominant, simply unbeatable.

"They could always make a comeback, so we have to keep an eye on them."
