McLaren's long-running title sponsorship deal with Vodafone will end later this year.
The partnership began in 2007, but it had been widely expected since last season that the contract would not be renewed when it ran out at the end of '13. In a statement issued by the team on Thursday, McLaren said that a replacement title sponsor for 2014 would be announced on Dec. 2.
McLaren team principal Martin Whitmarsh said: "We're immensely proud that, having been set a number of ambitious challenges by Vodafone back in 2007, together we've met or exceeded each and every one.
"Our focus is on continuing to drive results for all our partners throughout the 2013 season and we look forward to making a major title partnership announcement towards the end of the year."
