We know that we don´t know.If this was the potential of the car (which we don´t know) considering they ran the new rearend already in the Barcelona test and Liuzzi posting the quickest lap it does not look like they found a lot of time yet.
considering RB suppossed to "hold back 3tenths" and all teams stepping up their pace in the last test in barcelona the 107% is quickly back as a priority on HRTs agenda .
