Why some teams chose a two-stop race during US Grand Prix

Leave a comment

By no means a classic, Sunday U.S. Grand Prix was all about controlling lap times to achieve strategic objectives.

Pirelli opted to bring the hardest two compounds in their 2013 range to Texas. Combined with a track surface that’s not too abrasive, that meant that the fastest way from lights to flag was always going to be a one-stop race, as it was last year.

Degradation of the tires was relatively low overall, but teams had to spend Friday and Saturday collecting as much data as possible on both medium and hard compounds, to calculate their optimum race pace and the right point in the Grand Prix to switch between them.

While I suspect everyone set out with the intention of completing just one pitstop, we did see a few opting to make two, in either an attempt to free themselves from early race traffic and run shorter stints in clear air at a faster pace, or because of poor tire management and running out of grip with a handful of laps still to go.

Those that tried to free up their races with two stops did so because they had no real choice. To run for long spells in queues of traffic overheats the car, hurts the tires much more and can lose way too much overall race time. DRS often gives little advantage when a string of cars all benefit from its usage at the same time and on a track that only really has two clear cut overtaking places, being held up like this can frustrate drivers to the point of making mistakes. It’s often more advantageous to abort plan A, even though theoretically quicker, to put your driver onto a different part of the race track with some fresh tires and tell him to go for it.

It’s no surprise that the guys at the front of the field all stuck with their one stop plan and managed to go as deep into the race as possible on the medium compound, to minimize the risk of getting into trouble with the hard compound towards the end. It was a safe, relatively risk free strategy that the front runners were all able to deploy as the field spaced out enough to ease pressure on each of them.

The early safety car of course played right into the hands of those on the one stop race, allowing them three less racing laps with which to take life from their used medium tires.

The main strategic decisions then, came from teams and drivers managing the use of their tires, knowing when to push and when to hold back, when to deploy KERS and when make the switch between compounds. This is where the work from Friday’s practice sessions really paid off and those that had the best understanding were able to be pro-active, whereas those who were caught out by changing conditions, higher fuel loads or race traffic, could do nothing but react.

There were the normal mixture of successes and failures at the Circuit Of The Americas, but one thing that’s become thoroughly normal in recent times is that Sebastian Vettel and his entire Red Bull team got things exactly spot on again.

A great start, laptimes managed to perfection to deliver optimum stint lengths and the guys in the pitlane even managed a new world record pitstop time on the sister car of Mark Webber. All in all, a decent day at the office.

F1 Paddock Pass: 2017 launch roundup (VIDEO)

The NBC Sports Group original digital series Paddock Pass returns today with a recap of the remaining launches of the 2017 Formula 1 cars that occurred over the weekend.

Williams was first to reveal a rendering of its 2017 car, but it wasn’t a formal launch. Sauber’s online launch properly kicked off proceedings last Monday, before Renault, Force India and Mercedes did actual launches, and then Ferrari (online) and McLaren (in Woking) both launched on Friday.

Official launches then followed for Williams, Red Bull, Haas and Toro Rosso over the weekend. Haas had pictures of its car leak the day before its planned launch as it was a filming day on track.

In this edition of Paddock Pass, NBCSN pit reporter and insider Will Buxton and producer Jason Swales recap the remaining cars revealed over the weekend.

Previous Paddock Pass editions from this week are below:

Testing continues this week with days two through four of the first test at Barcelona.

Alonso’s McLaren struggles on first day of F1 tests

MONTMELO, Spain (AP) Troubled Formula One team McLaren has gotten off to a wretched start in preseason testing.

Fernando Alonso spent most of the first day waiting to get back out of the garage after his car broke down following just one lap at the Circuit de Barcelona-Catalunya on Monday.

What the team identified as an “oil system” malfunction to its Honda-made engine kept the two-time world champion out of action until after the lunch break. Back behind the wheel, his 29 total laps was the lowest amount of the 11 drivers who participated.

Alonso also posted the second-slowest time, more than three seconds off the leading pace set by Lewis Hamilton in his Mercedes. Only Sauber’s Marcus Ericsson was slower.

“It’s disappointing,” Alonso said. “You work for three months and at the track on the installation lap something breaks down and you lose the day.”

This misstep is the latest technical hiccup to plague McLaren since it paired up with Honda.

One of F1’s most successful teams with eight constructor titles and 12 driver titles, the British outfit has struggled since it switched from Mercedes to the Japanese automaker before the 2015 season.

After earning just a combined 27 points from Alonso and Jenson Button in the first year with Honda, the team showed some growth last season with 76 points and two fifth-place finishes. But that is still a far cry from the glory days of the Woking-based team whose last race win was in Brazil in 2012.

For his part, Alonso hasn’t won a race since he claimed his 32nd victory back in 2013 at the Spanish Grand Prix while with Ferrari.

“It is fair to say that after the difficulties we had the last three seasons, it’s a nice temptation for the media,” Alonso said.

“From the point of view of the team, we are disappointed and sad to arrive to the first day of testing and not run.

“We are focused on what we have to do to make up the lost time. We know that we have four days for each driver and now one day is gone to prepare for the world championship.”

Stoffel Vandoorne, who has replaced Button, will get his turn for McLaren on Tuesday.

McLaren team chief Eric Boullier acknowledged that the relationship with Honda is far from perfect.

“It is like any marriage, you can have some ups and downs,” Boullier said. “We went through a lot of stress through the last couple of years, but we have a positive and constructive relationship and I don’t expect this to change in the future.”

The opening test will run through Thursday.

The track near Barcelona will host a second round of testing from March 7-10 before the season starts at the Australian GP on March 26.

Steiner: Haas is ‘a lot better prepared’ after this day one

Last year’s first day of testing at Circuit de Catalunya-Barcelona for Haas F1 Team was both exciting and tense all at once.

As it was the first official day of running for the team, questions abounded over whether the new team would bank laps and if so, how would they get on. They did though with Romain Grosjean completing his first 13 laps in the morning session.

Luckily, having had a full year to acclimatize to Formula 1 and get in the rhythm of how this all works, Haas was able to have a smoother first day of testing in 2017, even despite an incident for Kevin Magnussen in his first day aboard the team’s Ferrari powered-VF-17 chassis.

“The plan was to do more, but that’s how the first day goes sometimes,” said Haas team principal Guenther Steiner. “We had a few issues, but that’s normal. They are to be expected when you have a new car and we sorted them out. We are here to learn and that is what we did.

“Our learning process is a lot better than last year because our people have worked together for a year now and we know more about the car. We are a lot better prepared.”

Magnussen ran through Pirelli’s hard, medium and soft compound tires on the day. An incident at Turn 10 damaged the front wing assembly but didn’t stop him from completing 50 laps.

“We had a few issues, but the good thing is that they were small issues,” Magnussen said. “Even though they stopped us from some running, it wasn’t something that is at all worrying for the coming days. It’s kind of the typical baby problems you have with the cars when they’re completely new. Except for that, the first feeling of the car is nice. It’s good to finally get that feeling of the car after looking at it, and all the anticipation for the faster cars. It’s a good feeling. Today’s been a day I’ve enjoyed a lot.”

The Dane continues tomorrow before Grosjean runs the last two days of testing.

Ron Dennis named to U.K.’s Ministry of Defense advisory panel

Ron Dennis’ post-McLaren world will involve politics of a different kind, rather than the politics inside the proverbial “piranha club” that is Formula 1.

Dennis, who officially stepped down as McLaren chairman over the winter as part of a significant organizational restructuring, was named Monday to a new advisory panel outlined by the U.K.’s Defense Secretary, Sir Michael Fallon, during a speech at the University of Oxford.

Per a release, the new Defense Innovation Advisory Panel will look to “encourage imagination, ingenuity and entrepreneurship” to help maintain a military advantage in the future.

Dennis was named alongside two others, Innovate UK Chief Executive Ruth Mckernan, and retiring GCHQ Director Robert Hannigan. That trio join veteran British astronaut Major Tim Peake on Fallon’s panel.

“There can be nothing more important than our national security,” Dennis said in the release. “And I’m enthusiastic to be among the first of those named to this world-class Panel, who have joined MOD to spearhead their efforts to innovate across the organization, from technology to culture – challenging the status quo, staying ahead of the curve through change and innovation.”
