Following Friday practice for the Spanish Grand Prix, both Red Bull drivers offered positive feedback on their team's performance upgrade this weekend.
The RB13's new aerodynamic upgrade was not quite as visually striking as expected, but appeared to deliver a step in performance relative to Mercedes and Ferrari on Friday. Max Verstappen finished the second session 0.21s off Sebastian Vettel's Ferrari in fourth and 0.63s off Lewis Hamilton at the top of the timesheets but believes the update had delivered solid progress.
"I think [it's] a bit more positive, I think we made a good step forward, we are a little closer to Ferrari and Mercedes brought a very good update so I think they are still ahead, but it was a positive day," he said.
