Oct.13 (GMM/Inautonews.com) Sebastien Buemi must up his game if he wants to practice on Friday morning ahead of next month’s 2011 season finale in Brazil.

Toro Rosso has told the Swiss, and his teammate Jaime Alguersuari, that whoever has the least amount of points after the penultimate race in Abu Dhabi will give up his car at Interlagos to French hopeful Jean-Eric Vergne.

Vergne, the latest cream of Red Bull’s young driver programme, will kick off his new Friday morning duties this weekend in Korea at the wheel of Alguersuari’s STR6.

“Jaime sits out the session because the last time a driver was replaced on Friday morning, it was Sebastien Buemi who gave up his seat to Daniel Ricciardo,” the Faenza based team said in a statement.

Vergne will sit out India because it’s a new circuit, and will return on Friday morning in Abu Dhabi “replacing Buemi”, the Red Bull junior team added.

And for Brazil, “whichever of the Toro Rosso drivers has the least points will give up his seat to Vergne for FP1″.

Currently, three races before Brazil, Buemi trails Spaniard Alguersuari by three points.

And also looming in the background is Red Bull’s other young hopeful Daniel Ricciardo.

“In the next couple of years not only the loss of practice laps is threatened, but also the complete loss of their seats,” noted Germany’s Auto Motor und Sport.
