A frustrating Friday at the French Grand Prix for Ferrari only grew more fretful, as Sebastian Vettel admitted that the Scuderia's upgrade package for Paul Ricard did not work as well as hoped. Ferrari brought a new front wing to Le Castellet, as well as a new floor, but some elements have seemingly been deemed unusable in the race.
Mercedes were one and two in both FP1 and FP2, even though Lewis Hamilton spun on his flying lap in the afternoon session.
Vettel trailed Charles Leclerc in both sessions on Friday and confirmed that the performance gains he had been expecting in France largely failed to materialise.
The discovery will have only served to darken the mood in the Scuderia garage after the FIA ruled that they would not review Vettel's Canadian Grand Prix penalty, confirming his second-place finish behind Hamilton.
Summing up how the new parts felt, Vettel told reporters: "Not so good, to be honest, [there is] a lot of work ahead of us.
"[They] didn't bring what we were expecting, so we'll see what we can try and find overnight, to maybe be a bit better off tomorrow."
