The Mercedes driver was under pressure from the Ferrari before running wide at turn one on the penultimate lap, but the team confirmed that both cars suffered with a brake-by-wire issue in the final lap.
“It’s such a pity to have that two laps from the end. Two laps!” said Rosberg after the race.
“If it happens with a bit of warning, then OK, I can drive to it. But it happened in the middle of a braking zone and so I just went straight on.
“Kimi was in my blind spot so I didn’t actually know where he was, otherwise maybe I could’ve defended into turn two, but I had no idea where he was. And so that’s really disappointing after what felt like such an exciting race to me.”
Rosberg had been running second throughout the majority of the race, but had been forced to pass both Ferraris on track multiple times after falling behind at the start and during pit stops.
“Passing the red cars was a very big enjoyment, for sure,” added Rosberg. “I was on full attack mode.”
“After the start I was disappointed to be fourth and I had to fight back because I could see Lewis getting away at the front. I didn’t like that. I had these two red cars in between and just went for it and it worked out, so that was good.”
Rosberg has moved into second place in the championship on 66 points, just one ahead of Sebastian Vettel.
