Vauxhall will return to the British Touring Car Championship next year after linking up with Power Maxed Racing.
The team will field a pair of new Astras, and will be a full manufacturer-backed operation.
The British manufacturer was last represented in 2014 when team BMR ran a pair of Insignias in the first half of the season.
Their last foray as a factory team was in 2009 when Fabrizio Giovanardi narrowly missed out on capturing a third straight title in the S2000 Vectra. Their partner during that ultra-successful period, Triple Eight Racing, currently run MG's factory racing effort.
"We are incredibly pleased and proud to be working with Vauxhall and to be the team that brings this iconic and highly successful brand back to the BTCC," Power Maxed boss Adam Weaver said. "The all new Astra is a fantastic car and it is no surprise that it was voted 2016 European Car of the Year – it will make a show-stopping BTCC challenger."
"It is fantastic to be welcoming Vauxhall back to the BTCC as a manufacturer entry," series director Alan Gow added. "Its history and pedigree is there for all to see and I have no doubt that the highly professional and experienced team at Power Maxed Racing will be great partners."
PMR fielded a pair of Chevrolet Cruzes last season for Hunter Abbott and TV actor Kelvin Fletcher, who was replaced by former PMR driver Dave Newsham at two rounds.
Newsham has revealed that he is working to acquire a budget to return to the BTCC in 2017 after spending most of last season racing in British Rallycross.
