McLaren racing director Eric Boullier says that despite the team's head start on its 2017 challenger, it will continue to update its current MP4-31 from Spa onward.
The Woking-based outfit has produced a huge effort this season in its bid to restore its former luster, updating its package as frequently as possible on both the chassis and power unit front.
McLaren will continue its push for improvement after the summer break, according to Boullier.
"There will still be some car developments after the shutdown," said the Frenchman.
"Every development we are doing is obviously applicable to next year's car, so we focus on this and on next year's car."
Its engine partner Honda won't be languishing either and is fully intended on making the most of its remaining development tokens in the second part of the season, although its focus on 2017 has already been initiated.
"We will not give up with this year," said F1 engine chief Yusuke Hasegawa.
"But we have to start work on 2017, so when we have to change our resources to 2017 is a very difficult decision."
