Red Bull advisor Dr. Helmut Marko revealed that Red Bull and Max Verstappen are not considering the installation of a fourth power unit, stating that it is not an option at the moment.
Verstappen was forced to use his third engine in Hungary after Honda found a crack after qualifying in Hungary. The Dutchman is likely to take grid penalties, should the team decide to replace the power unit.
“Spa is not yet an option for redeeming the grid penalty for Verstappen. First, we want to wait and see if there are any possibilities with the engine. Moreover, Ferrari have a similar problem and are in talks with the FIA,” Marko told Motorsport Magazin.
“We have to look at what the optimal circuit is to be able to catch up and where we can pay the penalty.
“I think America is pretty much fixed and so are the other important dates,” Marko added. “In terms of the kilometers we still have to travel, that means we probably have to use a fourth engine.”
