McLaren sporting director Eric Boullier insists that the side will not be distracted by 2019's agreed aerodynamic rule changes.
Boullier is determined that his team's focus should stay solely on this season's campaign.
McLaren sit in fifth place in the constructors' championship after seven races, but the team are still not fully satisfied with the performance of their car.
There are 14 races left of the campaign and Boullier believes there is still much more to come from the MCL33.
"There's still time to develop this car," Boullier said.
"Potentially curing the low-speed lack of grip which has a big impact on top performance.
"(Also) to understand what's wrong and to not repeat any kind of platform mistakes in the future.
"Those are two reasons why we should carry on.
"We also need to make sure we don't compromise next year's development as well as understanding the car. That's the balance which we are working on.
"We are flat out on trying to cure these car issues, and to make sure we understand it, and obviously we will start soon on next year.
"We have 100 per cent confidence in the group of people we have at McLaren.
"We can blame some issues on the car. Definitely I think the car this year is not the car we were expecting to have.
"It's just a matter of understanding why and making sure we have the right vision and leadership for the future.
"I believe in the people we have in place today. There is a great talented bunch at McLaren."
