The event, which pits winners from various motorsport series competing in identical cars and being held at the Thai capital's Rajamangala stadium for the first time, saw Germany comfortably beat the French pairing of F1 driver Romain Grosjean and rally driver Sebastien Ogier by two heats to nil in the final.
"Even Michael hasn't managed six titles in a row before so this is something special," said Vettel, who will be aiming for the individual title on Sunday.
Schumacher, winner of a record seven Formula One championships including five in a row for Ferrari, said he and Vettel would be defending the title again next year.
"For sure we're going to be here, that's a must," said the 43-year-old, who retired from Formula One for the second time in November.
"Actually, my lucky number is seven so we are going to push hard." (Reporting by Alan Baldwin, editing by Greg Stutchbury)
