On Sunday, Rosberg led a Mercedes one-two from pole and by the end of the opening lap, had worked up a lead of almost a second over his team-mate.
That advantage slowly built up over the field throughout the first stint. Schumacher was Rosberg’s closest threat until the first round of stops commenced.
The seven-time champion was on course for a podium finish at least on pace but things fell apart for his side of the garage as he exited the pit lane. The right front tyre wasn’t attached properly, forcing retirement half a lap later.
Rosberg however was able to extend the stints out in clear air, setting a pace the rest couldn’t match as they were pursuing or battling for track position. Mercedes’ plan was to execute a two-stop race while rivals burned through tyres fighting one another and committed to a three-stopper.
With Rosberg still leading following the first stops, he unleashed the Mercedes trump card – oddly enough its tyre management. For a team that had burned through Pirelli rubber in the past two races, Rosberg could coax laps out of his tyre that others couldn’t quite manage.
The McLaren of Jenson Button had inherited the role as pursuer following Schumacher’s retirement and was well on his way with a three-stop strategy. McLaren had swapped both of its drivers onto option tyres earlier while Mercedes selected them for the middle stint, leaving Rosberg to nurse them while Button loomed closer
“His win in China was one of the most convincing of the year”
It meant that while Rosberg still had to extend the tyre life, Button was cutting into his lead so that when it came time for Rosberg to make his final stop, Button took over the lead.
Of course the Briton would be back into the pits for a final stop that would drop him behind the sole remaining Mercedes, but a delay fitting the rear left in his third and final visit to the pits put him out in traffic and gave Rosberg all the breathing room required.
By the end, his winning margin stood at over 20sec, a dominant performance as the two McLarens of Button and Lewis Hamilton rounded out the podium.
“His win in China was one of the most convincing of the year,” Ed Foster remarked for Motor Sport at the end of the season. “He was on pole by over half a second, which was pretty special considering that the gap from second to ninth was just one second, and then won the race by over 20 seconds. It was a display that left you convinced that Rosberg really should be classed as one of the top drivers in Formula 1.”
For Rosberg himself, it was a win that had been a long time coming but there was a great deal of relief he’d finally managed to do it.
His switch to Mercedes as a works outfit was a move that eventually brought with it a world title, but in the early years of the Mercedes F1 journey in the 2010s, that looked a long long way off.
“It’s been a long time coming for me, and for the team as well over the past two years and a bit,” Rosberg said, relieved to have the weight off his shoulders post-race.
“Now, it’s finally here, it’s just amazing and it’s just nice to see how quickly we are now progressing. I didn’t expect to be that fast today. I expected that we had a good chance to be in front, but I was very happy today with the pace I was able to go in the race.”
