F1 mid-field fighters McLaren, Aston Martin and Alpine indicates their worries regarding the problem with their clutches, when the Formula 1 host the sport’s first sprint qualifying session at the British Grand Prix at Silverstone. The trouble-hit teams may avoid Free Practice 1 in order to protect their clutches for the entire weekend.
Silverstone will present the new session in this season. Friday’s second practice session will be replaced by a mini-Grand Prix over 100 kilometres sprint-race. In a regular free practice between 120 and 170 kilometres are covered, according to Auto, Motor und Sport. Nevertheless, these three teams are dissatisfied and have reported it to the FIA.
And yet, from the teams’ point of view, something is changing. The parc fermé will be moved forward by one day. With qualifying on Friday, the cars may no longer be touched. Exceptions are the brakes, spark plugs, filters and damaged parts.
But the clutch is not one of them. And it’s now causing three teams great concern. Aston Martin, Alpine and McLaren normally change or service their clutches after the two Friday practice sessions. That’s no longer possible with the sprint race schedule.
Aston Martin team manager Andy Stevenson is annoyed: “These clutches were built for a different purpose; they need new shims and servicing after 300 kilometres. If we had known before the season what to expect, we would have built different clutches.
“If we have to drive the whole weekend with a clutch without refreshing it, we can’t guarantee if it will last. If the FIA doesn’t give in, we might have to skip a practice session. That can’t be in the spirit of the invention.”
Until now, the Formula 1 governing body FIA has rejected demands from these teams to revaluate the regulations surrounding clutch changes for the sprint races, but the pleas have reportedly been swept aside by FIA delegates, who say: “Then just do fewer practice starts.”
Alan Permane of Alpine does not agree with this explanation. “It has nothing to do with the number of starts. It’s just wear and tear. The clutch is in use all the time. The shifting is the problem, not the starts.” All the teams use different clutches and Mercedes’, for example, can handle not 300 but 700 kilometres.
Not all teams have this problem. Mercedes uses a new clutch model that also manages 700 kilometres at a stretch. Aston Martin had already asked its engineering partner but received a rejection. There are not enough units for two teams.
At the second Spielberg race, there will now be another discussion with the FIA in the hope that a compromise can be found. Otherwise, Stevenson fears, “If the FIA doesn’t relent, we may have to skip a practice session. That can’t be in the spirit of the inventor.”
