Rosberg’s one engine failed from allocated four power units at Monza, since then, the German has had to run his current unit older than Hamilton, which could leave the championship runner-up at a difficulty on Sunday.
“It’s been a good start here in Abu Dhabi, but it will be a tough weekend for me as I have quite a high mileage engine in my car,” Rosberg said.
“After the Monza problem, we have had to stretch the engine life more than we had planned over the 19 races, so I definitely have a small lack of power on the straights and therefore need to make up extra time in the corners.
“It will be a big battle with Lewis here. He didn’t really bring together his quick laps, so it will be even closer tomorrow I’m sure. I’m looking forward to it and I definitely want to win this race and give the boys in the garage a reason to celebrate at the end of the season.”
Team-mate Lewis Hamilton also admitting that, “race pace doesn’t feel very good”.
“The long run pace doesn’t feel quite as strong so that’s something I need to work on,” Hamilton said.
“I’ll probably make some more tweaks tonight and hopefully tomorrow it will be better. It’s very hard to overtake here, so of course it’s better to be up on pole. But that doesn’t mean it’s impossible to win from further back.”
