It was also the fifth consecutive Drivers’ Championship won by the Chevrolet cars run by the RML Group.
“This has a special taste because one month before the beginning of the season I did not have a drive,” said Muller.
“Then we managed to put a programme together without the backing of a manufacturer. Budget was low and we had to take care of everything. The whole team did a lot of sacrifices.
“But now we have the pay back for this. And I must thank RML and Lukoil for giving me the opportunity to clinch another world title,”
Muller joins Citroën and nine-times WRC champion Sebastien Loeb in 2014.
He said: “The championship will be interesting, because if you add Tarquini and Huff you have a total of 15 FIA world title on the grid. We just need to call Andy Priaulx back...”
Muller had already won the WTCC title in 2008 for SEAT Sport, 2010 and 2011 for Chevrolet.
Norbert Michelisz converted his pole position into his first victory for Honda, giving the Japanese manufacturer a special triumph on its own playground.
Yvan Muller finished the race in third position, behind the Yokohama Trophy winner Alex MacDowall, and clinched his fourth WTCC title.
The first race at Suzuka was split in three parts: the early laps were full of action with close fights for the point position between several group of cars; halfway through the 26-lap distance drivers adopted a more conservative pace; the in the final laps the battle intensified again with plenty of contacts and overtaking.
And this cost Tarquini and Monteiro the possibility to make Honda’s result even greater.
Michelisz said: "It has been a dream weekend! Pole position yesterday and victory today. It was a perfect race. I took a great start and was able to create a gap in the first laps. The car was so good that I did not even need to push to the limit.
"I was focusing on not making mistakes and when my engineer told me on the radio that Tarquini had had a puncture, I eased my pace a bit. I really wanted to win my first race for Honda, and this was the perfect place to do it. I’m really proud of myself and of the team.”
