Nico Rosberg's healthy lead of 29 points, worth more than a race win, was slashed down to a paltry four following his retirement and title-rival Lewis Hamilton's victory at the British Grand Prix on Sunday.
The German retired his car with gearbox problems just after half distance on lap 29, having led from the start, winding up the upper hand that he held over teammate Hamilton in the last three races.
"I never want to see a teammate fall behind - I always want to battle it out," said Hamilton, who inherited the lead.
It was Rosberg's first DNF of the season, in which he had finished in the top two in every race culminating into eight consecutive podium finishes. It also ended a points-scoring streak that stretched 17 successive Grands Prix since last year.
Rosberg, winner at Silverstone in the preceding season, also failed to finish his first British GP in what was his ninth appearance.
"It's a pity what happened as I lost a lot of points in the championship," Rosberg said. "It's a shame for the race in a way, as it could have been a great battle against Lewis."
