Rumour has it Red Bull are threatening to test
If Red Bull think they would escape with only a reprimand they are deluding themselves.
If they did and I were the FIA I would throw the book at them, for blatantly breaking the rules. With the recent Mercedes and Pierelli rulling the FIA were partially found to be a t fault hence why they are paying a third of the costs. This would not be the case if Red Bull did a test.
