Following Friday practice for the Spanish Grand Prix, both Red Bull drivers offered positive feedback on their team's performance upgrade this weekend.
Max Verstappen believes Red Bull have taken a significant step forward with their upgrade package at the Spanish Grand Prix and can close the gap on Mercedes and Ferrari. Will the Spanish GP produce its 11th different victor in as many years?
The team will be hoping their RB13 vehicle can claw back some of the pace they have lost on the frontrunners.
"The lesson that we learned a year ago was to look at all our competitors", Arrivabene said.
"I'm not sure what we can expect from this weekend", said the Spaniard.
On Thursday, amidst rumours of an entirely new Red Bull auto being introduced for the race, Daniel Ricciardo downplayed speculation, admitting: "It's still the same vehicle itself". For both Mercedes and Ferrari, finding those last few tenths of a second won't be easy. "It's big aero stuff". The real mechanical side of the vehicle, you've kind of got what you've got, it's mainly bits which are predominantly aero, sidepods, wings and all that kind of stuff.
In the last race in Russian Federation, the lead Red Bull was 1.711s off pole and the closest it has been this year was 0.776s in the preceding race in Bahrain.
Ricciardo's isolated outing also left him as the only driver to finish the race to not be lapped by the leading pair, which he could take some comfort in.
The Maranello squad has hit the ground running with its 2017 vehicle, winning two of the first four races. The 35-year-old is one of only two drivers now on the grid to have won the Spanish round twice.
"If we can close the gap already a little bit, that would be a good target". We made some progress but we knew it still was not going to put us up with Mercedes.
"The new regulations are still very immature and we will definitely get stronger", he told Red Bull's Speed Week.
