McLaren racing director Eric Boullier says the team's development push will remain "relentless" over the winter.

Boullier has been "encouraged" by the team's "definite progress" this year, but knows a lot more work needs to be done to put McLaren back closer to the sharp end.

"This year has been a huge challenge for the whole McLaren team, but our definite progress as the season has unfolded has been very encouraging," he said ahead of this weekend's season finale in Abu Dhabi.

"Our push for development has been relentless and this will only continue into the winter as we prepare for next season."

Jenson Button and Kevin Magnussen both finished in the points in Brazil two weeks ago and with double points on offer this weekend it will be important to replicate that at the Yas Marina.

"With double points at stake, we are fully focused on securing the best possible finish in order to consolidate our [fifth] position in the constructors' standings, and the aim for the whole team is to conclude the season with a positive result," Boullier added.

"It's important that we carry strong momentum into the closed season, so it would be great to reward the hard work of everyone at the factory in Woking with some valuable points," he continued.

"At Yas Marina there will be some big winners and big losers as the chequered flag falls, thanks to double points, so, providing we can maintain our recent improved pace, we are aiming to be in the former camp.

"As usual, we will be pushing from the moment we arrive to configure the optimal set-up on our car, so that we can take as much valuable information into the winter development phase as possible. Here's to an exciting weekend for both the team and the sport as a whole."

Meanwhile, with McLaren switching to Honda power units next season, the Woking outfit is gearing up to bid farewell to Mercedes: "The race in Abu Dhabi marks the end of a very significant era in McLaren's history, and we would like to thank Mercedes for our hugely successful and historic partnership over the past 20 seasons," Boullier concluded.
