Well, Redbull seemed to have won the development race in Austria but after what Ferrari did today im sure Newey wont sit with his arms crossed. Its clear that RedBull does not have the best chassis and engine.
My only hope is that they were using a spec2/3 for the power, cause it seemed a bit underwhelming. That or they are waiting for fuel and intake in Russia to turn things up.
