Aug.27 (GMM) A Red Bull-style blown exhaust and diffuser layout is "in the works", according to Toro Rosso driver Sebastien Buemi.

Although still owned by the energy drinks maker, Faenza based Toro Rosso is now going it alone from a technical perspective, no longer receiving updates from Red Bull Technology in the UK.

Toro Rosso is the lowest ranked of the established teams in the constructors' championship, and concerned about falling further off the pace.

With all F1 teams except the newcomers now running a blown floor, Buemi said the innovation is "in the works" for the Ferrari-powered STR5.

"We just want to do it thoroughly and properly before we use it at a race weekend," the Swiss is quoted by German language Speed Week.

His teammate Jaime Alguersuari is confident the car might look stronger at the faster Spa-Francorchamps layout than at recent outings.

"If our closest rivals have tended to look stronger than us in medium to high downforce configuration, I am hoping that Spa might see us run more competitively," said the Spaniard.
