The famous HiQ branding will again be synonymous with Britain's premier motor racing series as it continues to sponsor the Teams' Championship, following on from two years of title sponsorship in 2008 and 2009.
The season will incorporate ten events and run the length and breadth of the country. Each event will include three points-scoring races.
Other venues to stage fixtures will continue to include Donington Park in Leicestershire, Thruxton in Hampshire, Oulton Park in Cheshire, Croft in North Yorkshire, Snetterton in Norfolk, Knockhill in Fife and Rockingham
BTCC Series Director Alan Gow commented: "Thanks to all our circuits and the British Automobile Racing Club for enabling us to be so ahead of the game in informing our competitors, partners, the media and public of next year's BTCC calendar.
By doing so, we also hope other high-profile motor sporting events can plan around these dates and hopefully avoid some of the ridiculous clashes that in recent years have proven to be highly frustrating for both fans and organising clubs, whose resources have been stretched to breaking point."
He added: "Above all, the BTCC in 2011 will continue to race at the premier motor sporting venues around the country - a geographical spread that is of huge importance to sponsors and which also enables hundreds of thousands of fans from almost every corner of the UK to see the BTCC in action in their own back yard. We very much look forward to seeing them again in 2011."
