Honda Racing F1
This was the first day of practice at a permanent race track since the Spanish Grand Prix weekend in early May.
We had fine weather with relatively high air and track temperatures during the sessions, particularly in the afternoon.
For this race, at Red Bull Racing Honda, Max Verstappen and Sergio Perez ran new PUs, as did Pierre Gasly at Scuderia AlphaTauri Honda and we had no major issues throughout the day, going through the basic programme and function tests for a new PU, in addition to the usual job of gathering data. It looks as though the competition will again be very close with our nearest rivals. In this situation very small gaps can make a big difference to the final result, so we will be paying close attention to the smallest details with both our teams to optimise our PU performance for qualifying and the race.
Spec is the same as only reliability upgrades are allowed; however, if more reliable, it can be pushed Harder, Better, Faster, Stronger ..
I asked that question in the Honda power unit thread page 1219. You might want to check out the responses there...
If you quote, then also quote Steven responding later when he read the rules and saw 'no performance upgrades allowed in-season'
