Renault says that it will make its upgraded power unit available at the United States Grand Prix, though it has not yet been decided whether Red Bull and Toro Rosso will use the updated engine.

Renault has held back on using its development tokens until this weekend's event but any changes for Red Bull and Toro Rosso will require drivers to sustain a grid penalty.

"We will have our new specification of power unit available to use in Austin," said Renault chief Remi Taffin.

"The principal changes involve the internals of the ICE to give improved power and efficiency. We know that introducing the new power unit will incur a grid penalty so the decision to use will be made in full consultation with the teams.

"At this point of the season obviously points are crucial so if circumstances allow then we will use on track.

"Whatever specification we do use, we are looking forward to Austin. Our reliability has been good in the last three races and performance more in line with our expectations; both our teams just need a clean weekend to show the improved potential of both packages."
