The Swiss, who won two British Touring Car Championships in the Nineties, has never finished higher than third in the world series.
He occupies that third position with four race weekends to go, 20 points behind Huff and 37 in arrears of three-times winner Muller.
The first of those is this weekend at Sonoma in California, which marks the first occasion that the WTCC has visited the United States.
"The Sonoma track is unknown territory for me. What I know is that it is a natural track, which could be compared to Spa or Brno in Europe, and that’s great news for me because I love that type of circuit," said Menu.
"I have never been to the West Coast of the US so I am anxious to go out to explore and discover San Francisco and the wine region.
“Regarding the championship, I am still in a great position to claim the title and won’t give up, although I also need Yvan and Rob to be unlucky at some point to have a real shot at it."
Following the two-month summer break, each of the remaining race weekends is worth a maximum of 55 points.
Manufacturer Chevrolet announced recently that it will leave the WTCC at the end of the season despite dominating the series since 2010.
