Toro Rosso is seemingly swimming upstream and won’t pursue developing an ‘F-duct’ system for its STR5.
Or, dare we say it, has Red Bull refused to design and develop one for them?
Aside from the three rookie teams, this means that the Faenza-based outfit will quite likely be the only established team not to run the downforce-spoiling device first pioneered by McLaren.
Toro Rosso’s Technical Director Giorgio Ascanelli (pictured) has explained that the decision is due to financial considerations.
"If I have ten Euros and am hungry, I would buy two sandwiches instead of three grams of caviar," he told the Italian magazine Autosprint.
"You might see some benefit after five months of development, but in that time we can improve and develop other parts of the car," he added.
Following McLaren’s lead, Sauber, Ferrari, Mercedes GP and Williams have each developed and tested their own iterations of the concept, with varying levels of success.
Mercedes GP boss Ross Brawn admitted during the Chinese Grand Prix weekend that the teams aspiring to match the increased straight-line speed gained by McLaren (as a result of running the device) are perhaps only now beginning to realise just how complex a job it is to package the ‘F-duct’.
Renault, Red Bull and Force India are expected to run the concept at forthcoming races.
