In the round-up: Pirelli’s Mario Isola says that the company were not informed about the work done to the Shanghai International Circuit before Formula 1’s return.

In brief

Pirelli “not informed” of track modifications

Pirelli’s head of motorsport, Mario Isola, says the tyre manufacturer were unaware that Shanghai International Circuit management had approved an application of liquid treatment on the circuit’s asphalt prior to the Chinese Grand Prix weekend.

“What’s new is this layer of bitumen they put on top of the track,” Isola said in Friday’s team principals press conference. “There was no resurface, no changes, a few changes to the kerbs but not to the track.

“As usual, we measure the track roughness and the level of grip with our system and we found some, let’s say, inconsistencies in the grip around the circuit. I believe that also drivers highlighted this. The most important information is that I believe the track is going to change quite a lot during the weekend, because this layer of bitumen is disappearing, especially on the race line, and not on the other lines.

“When they run over this layer, the level of grip is good. So I’m expecting that on the race line it will be a bit worse compared to the other parts of the track. But it’s just an assumption, because we were not informed of this kind of work on the track. So, we are trying to understand ourselves what is going to happen, but a lot of track evolution is expected.”

Ocon relieved he can change set-up

Esteban Ocon intends to take advantage of the opportunity to change his car’s set-up after today’s sprint race having not got the most out of his upgraded Alpine so far.

“I feel like we didn’t maximise the potential of the car today, unfortunately,” he told the official F1 channel. “That’s probably the first time this year that this is the case.

“I think there was probably more in it today. With only one session unfortunately we didn’t put everything together. Some performance left on the side, which is a good thing that the parc ferme opens again so we can change for the next qualifying.

“So we’ll try and race tomorrow like this early in the morning and after that try again with a different set-up in the car and see what we get”

Ferrari fastest in WEC practice

Ferrari set the pace ahead of Porsche Penske in the first day of practice for this weekend’s Six Hours of Imola.

The number 50 car of Antonio Fuoco, Miguel Molina and Nicklas Nielsen was fastest at the end of Friday’s second practice session ahead of the number six Porsche Penske of Laurens Vanthoor, Andre Lotterer and Kevin Estre. The number 83 Ferrari of Robert Shwartzman, Robert Kubica and Yifei Ye was third ahead of the number eight Toyota of Sebastien Buemi, Brendon Hartley and Ryo Hirakawa fourth.

The number six Porsche Penske team lead the championship after their victory in the opening round of the season in Qatar, ahead of the number 12 Jota Porsche of Callum Ilott, Will Stevens and Norman Nato.

Comment of the day

After the first sprint qualifying session of the season produced an upset result as Lando Norris had his pole time reinstated following confusion over track limits, bernasaurus would like to see F1 take its rules to a different kind of extreme…

The amount of time and effort devoted to track limits and arguing and stewards and technology and rules and then arguing again… Since F1 is open to trialing new stuff these days, why not have a race without limit violations at all? Maybe a small marker so nobody tries to just rallycross their way straight through Maggotts and Becketts.

It was noticeable that the exit of Spoon at Suzuka – which I think was meant to be policed – clearly wasn’t during the grand prix and soon everyone took advantage of it. I wasn’t sure why Max Verstappen was going metres over when he’s miles ahead and risking the stewards issuing 47 retrospective violations on the penultimate lap.

I’m not saying this to defend Lando, rules are rules regardless of whether he gained an advantage or not. I just wouldn’t mind seeing what happens if we try it without rules.

    That Eurocup 3 article lead me to look up the race, and what I saw I thought honestly was a bit disgraceful. It’s been less than 12 months since a young single seater racer was killed just a few hundred metres away in very wet conditions in a junior formula race. And for something like this to happen just months later is ridiculous.

    I love Spa (and Eau Rouge) and I love wet racing as much as anyone here, but the dangers of these conditions at this part of the circuit are well known, and as much as I believe drivers should have to try to negotiate the conditions, we cannot be putting lives at a significantly greater risk.

      I should add – of course – I hope everyone is safe and alright.

    2. I think this was a bit different to what happened last year as conditions were wet but ultimately raceable when the race was started but deteriorated extremely quickly with a localised very heavy downpour just as cars were starting the last lap.

      Reminded me a bit of a GP3 race at Spa in maybe 2010 where it was completely dry and then suddenly as they got to the end of lap there was suddenly monsoon levels of rain out of nowhere that flooded the track only in that bit of track.

      Was crazy as you went from a camera shot at blanchmont that was totally dry to a shot from the bus stop where it was raining so hard you could barely see the cars.

        Oh I definitely agree that the conditions were raceable at the restart, and I praise them for the restart, but when it got to the final lap it was pretty clear that the conditions were no longer suitable, and I think the race should have been stopped or neutralised earlier than it was.

        Nothing wrong with the initial decision to restart though.

      I did think when the second fatal accident happened, maybe we should restrict the categories who race there.

      Spa is a dangerous track, the issue was in recent past, the drivers knew it was dangerous so they respected the danger. Now with increased safety and the fact that Eau Rouge and Radillion are easy flat, that respect has seemingly gone

  2. The issue with ignoring track limits is that your get into a situation where the runoff is no longer suitable because there’s effectively less of it.

    I recall at Indycar race at COTA where there was no track limits and everyone was using all of the runoff at turn 19.

    Result was cars were traveling faster than if they were staying on the track and reducing the size of the runoff. It was noted that the barrier setup was not designed for that so may not have been as effective had someone crashed there.

    As such in subsequent visits Indycar enforced track limits.

    1. Yes, I was going to comment that that IndyCar race (as well as most other US motorsport) shows us precisely what will happen — and I was all for it. I loved watching the drivers exploit the paved surface to the limit. I don’t know that IndyCar changed their mind because they felt it was necessary on driver safety grounds — after all, they steam into Turn 1 at Indianapolis at 380 kph with zero runoff — more that they just didn’t want unnecessary crashes and disruptions.

      Also, T19 at COTA is a rather extreme example where the runoff geometry creates a pretty sharp pinch point as cars merge back onto the track proper. There are plenty of other situations where the runoff may not be necessary to meet FIA Grade 1 standards and is there mainly to save amateurs from repair bills on track days.

      I know it was generally unpopular around these parts, but I appreciated Michael Masi’s more flexible approach to track limits, allowing kerbs and some runoff to be used on a race-by-race, corner-by-corner basis. I think of several corners at Imola and the Lesmos at Monza as places where the runoff is so limited and the gravel already so close that there’s not really a need to police the white line on safety grounds. Pundits and commentators often complained that the inconsistency was confusing, but I felt it was a more natural approach and reduced the amount of energy I needed to expend thinking about rules and regulations as opposed to simply enjoying the sheer pleasure of watching cars on the limit.

  3. Good guest appearance by Piastri & as for the COTD, since I already replied to it, I’ll go shorter here:
    That wasn’t really the case with Spoon, though, as lap time invalidations still happened there.

  4. OMG, F1 was forced to run on a billiard smooth track with acres of runoff, but not with every last track surface detail?! How will they ever survive.

  5. So, the racing line will end up with less grip than off-line?

    That’s… very interesting.

    1. Would be great for overtaking, in a real racing series.

  6. too many balls being dropped. Not enough pro-activity, probably points to systemic corruption, in a lot of places.
