Korhonen began Sunday with a 56.5sec advantage over Laurent Pellier in the all-Ford Fiesta Rally3 class. It was a buffer that allowed the young Finn to take a risk-free approach to the remaining four stages, cruising to the finish to win by 34.6sec.
The 24-year-old has scored a perfect 100 points from his four starts so far this year and, with WRC3 drivers able to count their best four scores from up to five rallies, he can now only be matched but not beaten. It means that, in the event of a new entrant equalling his efforts over the remaining rounds, the champion would be decided by tiebreak.
