F1 Grand Prix of Great Britain - Race

Everyone’s Silverstone race strategy suffered on Sunday


The thing about Formula One race strategies is that they need to be adaptable to cope with the unforeseen circumstances that the sport invariably throws up. No matter the plan, teams must react quickly to whatever’s thrown at them.

When the strategists at each team sit down after qualifying on a Saturday evening to ponder their options, they look at data; weather forecasts; the cars around them on the grid; their own confidence in their race pace; start performance; the amount of tires used and those they have left, as well as many other factors.

Between strategists, engineers, management and the drivers themselves, they come up with at least two or three of the most probable scenarios or plans. Those plans will cover things like what happens if they have a good start or a bad start; where they are after lap one and what they do if it all goes wrong, have contact and an enforced first lap pitstop. They’ll have a ‘plan A’ which is the optimum strategy and considered the fastest way to the checkered flag and a ‘plan B’ to cover the possibility of the tires not lasting their intended stint length.

Sunday, everyone’s optimum race strategy was compromised in one way or another, by a number of issues.

After the practice sessions, analysis showed the fastest way for the top 10 to complete the race was a two stop strategy, starting on the medium tire, stopping around lap 17 for another set of mediums, before finally stopping around lap 35 for the hard. Whilst that may well have been what most intended, excessive graining on the options, unforeseen tire failures and safety cars changed things.

When Lewis Hamilton had the first failure whilst leading on lap 7, nobody thought it would be the start of a chain reaction.

Felipe Massa’s Ferrari was next to suffer the same left rear failure at the same point of the circuit and Jean Eric Vergne followed shortly afterwards with a similar and spectacular blow out of his own. That one, not only brought out the first safety car that stayed out for seven laps, but clearly raised eyebrows amongst the teams. It was clear there was an inherent problem affecting left rear tires and that meant that teams had to decide what to do.

Some pitted under the safety car, some drivers were told by their teams to try and avoid kerbs, some increased tire pressures in their pitstop sets to try and stiffen up the sidewalls, but the teams and Pirelli furiously tried to work out what was happening.

Avoiding kerbs clearly compromises race pace, as does running with higher than preferred pressures, and therefore can have an impact on strategy, but the possibility of more failures has even more dire effects. Those that pitted mostly switched to hard, prime tires after many struggled more than predicted on options, but were still on for the two stop plan to work, so they tentatively continued with the championship leader out front.

Vettel controlled the race pace well in the lead, keeping Rosberg behind until ten laps from the end when his Red Bull Racing RB9 ground to a halt with a failure of fifth gear. With the car in an unsafe position and Race Control more than happy to slow proceedings down to prevent anymore dangerous failures, the safety car was again deployed.

This was the point where teams had to make crucial, race defining and split second decisions.

For Rosberg, now out in front, it was easy, he had a worrying tire vibration and enough of a gap behind to make the unplanned third stop without losing track position.

For those behind it was make or break time and whilst Alonso and Webber also dived in and switched to a late three stopper under the safety car, Raikkonen’s Lotus team decided to leave him out.

That decision was a bad one and ultimately cost Kimi a podium spot as he struggled on old tires in the closing laps.

Whilst stopping meant that Webber and Alonso lost places initially, the fresh mediums for the short last stint allowed them to push hard to the flag and pass with relative ease to take second and third places respectively. Their teams got it right under pressure, Kimi’s unfortunately didn’t today.

All the planning, data and analysis in the world couldn’t have prepared for today’s events, so in those instances success or failure comes down to the decisions of the drivers and their teams. Despite the obscene amount of Dollars spent on strategic simulation and predictive tools up and down pitlane, when it comes to making a last minute, split second decision in the heat of battle, it often boils down to good old fashioned human reactions under pressure. Some are better than others.

Porsche wins, champs crowned in rain-shortened Petit Le Mans

BRASELTON, Ga. – One of the more bizarre races in recent sports car history was called just prior to the eight-hour mark, as IMSA Race Director Beaux Barfield made the decision to end the 2015 edition of the Petit Le Mans powered by Mazda early.

It produced a surprise winner, as the GT Le Mans class No. 911 Porsche 911 RSR secured an overall victory courtesy of a storming drive from Nick Tandy and co-driver Patrick Pilet. Third driver Richard Lietz did not get to drive in the race.

Pilet has now secured the GTLM class championship, too, as a result.

Meanwhile Action Express Racing stormed from behind to win its second consecutive Prototype class championship.

The No. 5 Corvette DP of Joao Barbosa, Christian Fittipaldi and Sebastien Bourdais finished third overall – behind both the No. 911 car and No. 24 BMW Z4 GTE – but the result was enough to give it a class win and the class championship.

Other class champions include Jon Bennett and Colin Braun in Prototype Challenge in the No. 54 CORE autosport Oreca FLM09 and NBCSN IndyCar analyst Townsend Bell and Bill Sweedler in the No. 63 Scuderia Corsa Ferrari 458 Italia in GT Daytona. Like the Action Express pairing, Bell and Sweedler came from behind to win the title.

Other race winners were the No. 52 PR1/Mathiasen Motorsports Oreca FLM09 of Tom Kimber-Smith, Mike Guasch and Andrew Palmer in PC and the No. 73 Park Place Motorsports Porsche 911 GT America of Spencer Pumpelly, Patrick Lindsey and Madison Snow in GTD.

The race was slowed by 10 full-course cautions and a number of accidents, spins, and other off-course excursions.

It also featured a red flag of one hour and five minutes during the race, but the race was resumed.

Barfield explained the decision to call the race when he did in a post-race press conference with assembled reporters:

“So a big part of reconnecting with the drivers and competitors in this paddock has been really open communication,” Barfield said.

“For the basis of this decision, I go back to Watkins Glen. At Watkins Glen because of the imminent weather we had coming there and how it ended up being managed, we encouraged more open dialogue to gather as much information as possible for our decision process.

“As it turned out that was very successful how they communicated real time.

“So going into this event, with the weather being similarly predictably bad, we reestablished that. How we communicated and went about it the same way.

“Today was really similar to that with our attention to our attention to what was going on the track and on the TV screeens, and with looking at the radar. With my knowledge of this track having spent a lot of time here in the past. Having a quick car availbel for recon laps during the vents. All of our decisions were for gathering information from those different directions.

“Fast forward to the very end of the race, the last restart, I felt in my gut that with the visibility issues, you have to think about these issues that produce two problems.

“One is the grip, hydroplaning – whatever part of the world you’re from – where issues where drivers have less control. An often forgotten major issue is the visibility. Cars with downforce shoot up such a spray, it’s hard to see around.

“The grip issue was one and dealt with but we had some daylight. The visibility was a problem. But not as it great as it became in the last hour when we lost sunlight.

“The light with the track conditions gave me no comfort level to go back green that is. What I saw on track, the visibility issues I had with a Porsche on track, you had the speed they had, you’d have to drop into night with a sunset, I felt like I’d be putting driver out there completely blind.

“So this decision was made to pull the plug and do the checkered flag.”

Bottas: Williams turning focus to 2016 car

Valtteri Bottas has explained how Williams is beginning to turn its attention to the development of its car for the 2016 Formula 1 season as the team settles into third place in the constructors’ championship.

Williams has struggled to put up much of a fight to Mercedes and Ferrari at the front of the field in 2015, picking up just three podium finishes.

With five races to go in the season, the team sits comfortably in third place in the constructors’ standings, knowing that neither the 129 point gap to Ferrari ahead or the 69 point difference to Red Bull behind are likely to be bridged.

As a result, the team is now turning attention to its 2016 car, the FW38, as explained by Bottas in his post-Japanese Grand Prix blog.

“As we get to this stage of the season some of the focus is switching to next year’s car and for sure we’ve been developing the FW38 for a long time,” Bottas said.

“That’s the target until the end of the season – to look ahead and put us in the best place for 2016. But if we can also find something that benefits this year’s car then we’ll use it as we would like to get more podiums before the season finishes. And if we can get closer to Ferrari then all the better.”

Williams has looked most comfortable at the high-speed tracks so far this season, and with the likes of the Circuit of The Americas, the Autodromo Hermanos Rodriguez and the Yas Marina Circuit all to come, the team should be in good stead for the final leg of the year.

“Most of the tracks we’re still going to this year should be good for us, so that’s very positive,” Bottas said. “I believe the upgrades we introduced for Singapore gave us more downforce and worked well, so they definitively worked here too.

“We ran the same bits on the car at Suzuka and were competitive but, obviously, Red Bull and Ferrari have made improvements too and they’ll be very difficult to beat in the coming races.”
