Norris with great lap times on Mediums, McLaren really did nail their updates, huh? Also possible the C5 just doesn't last the entire lap and the Medium ends up actually faster. I remember that was the case for Bahrain during testing earlier this year, though it would be a little unexpected for Hungaroring to have as bad degradation as Bahrain.
I think the track is quite a bit warmer too today, so it's good to see that they're still fast. I think there was some concern they'd lose their pace as the temperatures ramp up.
That said, we still don't know until qualy and the race!
