Sebastien Ogier is desperate to end his drought at the Rally Argentina when the season resumes on Thursday.
The French Volkswagen driver is yet to taste success in Argentina, although he has three podium finishes at the event.
Ogier leads the World Rally Championship on 77 points to be clear of Mads Ostberg (42) and Andreas Mikkelsen (33).
He is eager to finally win in Argentina with co-driver Julien Ingrassia, but he knows the difficulties that will be awaiting them.
"The Rally Argentina is the only rally on the calendar that Julien and I have not yet won. This year will not be easy either, because we will once again be the first car onto the route," Ogier said.
"Whatever happens, I will do my best to improve my record here and to win the rally for the first time.
"Julien and I have had a great season so far. We have always achieved the best possible result. With this in mind, I am very optimistic about Argentina.
"However, the weather can be very tricky. Thick fog often restricts visibility, which is not very pleasant for a racing driver.
"As far as the surface is concerned, we must adapt from Mexico, as the gravel is much softer and the ground far sandier. That requires a different driving style."
Fellow Volkswagen driver Jari-Matti Latvala carries winning form into Argentina, having claimed victory in Mexico after a slow start to the season.
Latvala was victorious in Argentina in 2014, while British Citroen driver Kris Meeke took out the event last year.
