While also looking at costs with the V10Inside Red Bull's impressive 'Energy Station', a tug of war is presently in play for the services in 2007 of Tonio Liuzzi.
Junior team Toro Rosso's co-owner, Gerhard Berger, is making it clear that he wants to keep the Italian
on-board, but chiefs at Red Bull Racing reportedly want to promote him to the senior squad.
"Overall I think he's a guy we can build up into a quite good driver," the Austrian told Speed TV at Indianapolis on Friday.
California's Scott Speed is also likely to stay on board beyond 2006.
More uncertain, however, is the identity - and capacity - of the Faenza-based team's engine supplier for next season.
A contract to continue the V10-route with Cosworth exists, but there are also suggestions that STR could bow to the V8 alternative - possibly with Ferrari.
"I don't know if (the V10 option) stays in the regulation or not," he continued, "(but) if I look at the cost side, I think it's the most realistic thing."
