Will Stevens has played down the possibility of Manor introducing a new car before the end of the 2015 Formula 1 season and says the team is weighing up the long term benefits with an eye on next year.

Manor, formerly known as Marussia, was saved from extinction just weeks before the start of the 2015 season in Australia and lined up on the grid with an updated version of its 2014 MR03 chassis with last year's Ferrari engine.

Over the first half of the year Manor has steadily accumulated updates alongside new backers and sponsors with an initial goal of rolling out a new car for 2015 before the end of the year.

As the team prepares for the second half of the season after the summer break, Manor has signalled it could scrap the plan of a 2015 car and switch its efforts to 2016.

Stevens has confirmed he's received no news on a new car for the remainder of this season and despite seeking more performance from its current machine the British driver sees sense in looking long term for stronger gains.

"This year was always going to be tough, but I think the decision with the new car is going to be based heavily around what we want for next year and whether we would have a bigger opportunity to increase performance for next year by not bringing it in," Stevens said. "For me, personally, obviously I always want as much performance as possible but as a team we need to look at the bigger picture.

"In terms of performance you always want to bring as much performance to the car as you possibly can. I think as a team you've objectively got to look to the future and make a decision based on what financially and as a team is the best solution to put us in the best position for next year."
