"Frustration and disappointment, those things are not the most useful emotions to have," Autosport quotes Whitmarsh as saying. "We have three races to go. India was a solid performance where we were quick at the end but not quick enough at the beginning.
"We have under-performed in the couple of races coming here, so the motivation is very high.
"You can sense it in Lewis Hamilton, you can sense it is everyone in the team. We want to go out and win some more races before the end of this year. That is what we will focus on."
The Abu Dhabi Grand Prix takes place this weekend at Yas Marina.
