The Williams Formula 1 team will not be getting an early taste of its 2012 power plant, and may also lose veteran Rubens Barrichello.
The British team, currently Cosworth powered, will reunite the famous title-winning Williams-Renault alliance next year.
But Renault Sport F1 chief Jean-François Caubet played down speculation the new combination will get a head-start on the test track.
"Our philosophy is staying the same," he is quoted by France's autohebdo.fr. "We will probably not test before the end of the year, but early next year instead."
Meanwhile, Rubens Barrichello - the most experienced F1 driver - has admitted it is not a foregone conclusion that he will stay at Williams next year.
The veteran recently admitted he would like to see in his fortieth birthday next year with a third consecutive season at the famous British team.
"It's good to have a powerful engine behind you and I'm convinced that with Renault we will take a quantum leap," Barrichello is quoted by Tuttosport.
"But the team needs to show their interest just as I am showing mine, and then we can agree.
"I do not exclude the prospect of switching to another team, if Williams doesn't offer me a reasonable solution. But it's not a priority," he insisted.
