Formula 1 journalist Mark Hughes provides the answer when asked to comment on Scuderia Ferrari’s upgrades for the 2018 British Grand Prix, which helped German driver Sebastian Vettel score his fourth win of the season:
“I think the upgrades were very powerful and I don’t think the temperatures had much of an impact. Ferrari were actually harder on the rubber than Mercedes here – and they seem to have changed their emphasis towards qualifying now that they are confident of their car’s pace. This means a set-up biased towards qualifying pace at the expense of tyre deg in the race, feeling confident they could control from the front. Furthermore, Silverstone is now more power-sensitive than before – as so many of the turns are flat-out – and Ferrari now appear to have more sheer horsepower than Mercedes. So I think Ferrari just had a faster car around Silverstone than Mercedes. But I’m sure there are many more development twists and turns between the two teams coming.” – Mark Hughes concluded, as reported by Formula One’s official website.
