Red Bull faces the prospect of both cars starting its home race from the back end of the grid after Daniel Ricciardo and Daniel Kvyat admitted engine changes look likely in Austria.
The team arrives at the Red Bull Ring knowing the circuit which shares its name will expose Renault's power deficit to Mercedes and Ferrari, which it did in a brutal fashion last year. Both Ricciardo and Kvyat are on their fourth power unit - the limit allowed in the 2015 regulations - and think changing to a fifth in Austria is the most logical decision.
"It's likely, yeah," Ricciardo admitted in Austria's Thursday press conference. "We're definitely looking into it. We'll probably have a decision later tonight. It's likely we'll take a penalty here. If it's not here, it's in the next few, and we have to see what chance we have in Silverstone and Budapest."
In his own media session, Kvyat admitted: "The talk is ongoing at the moment. Decisions will be made a little bit later on. But it could be likely that it's possible, yeah. It would be logical to do it here."
The reasoning behind the decision to do it in Austria is because Red Bull thinks it will fare better in Silverstone and Budapest. Therefore taking the penalty in Austria limits the potential damage caused by an engine change at those races.
A change for either driver will result in a 10-place grid penalty. If the penalty cannot be fully applied, the remainder will be served in the form of a time penalty depending on the number of grid places left to be served.
