Max Verstappen says the introduce of Ferrari power to the updated Toro Rosso has been a success and ends the opening F1 pre-season test with all boxes ticked on his checklist.
The Dutch driver has completed 110 laps in total on the final day of the first test with the best lap of 1m 25.393s on soft Pirelli tyres to take fifth on the timesheet.
Despite a solid but largely unspectacular four days for both he and team-mate Carlos Sainz, Verstappen says Toro Rosso leaves the first test satisfied with a positive integration of the year-old Ferrari power units, having ditched Renault engines over the winter.
“I think in general over the four days what we did we had great reliability, we could do a lot of laps and that's always very important with a new car,” Verstappen said. “You have to get comfortable, the team needs to understand the car, I need to understand the car, and I think that all worked out. It feels good. Also the relationship together with them is all very positive. We help each other a lot and I'm very happy.”
With one eye already on the second and final pre-season test next week Verstappen has hinted at new parts to be experimented on the STR11, to replace any 2015 parts, as well as a new car livery at the team's official launch.
“We definitely will have some painting on it. You will see, it will be interesting,” he said. “[New parts] are all tested in the windtunnel. Our windtunnel works very well so it should also work on track but we still have to wait and see. I am of course looking forward to it but I think we can already be very happy with the four days we had so far."
