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.

Rosberg wary of engine power deficit in Abu Dhabi

Nico Rosberg is anticipating a tough weekend in Abu Dhabi due to a deficit in engine power caused by the high mileage on his current unit.

Rosberg and the Mercedes team have managed to avoid any engine-related grid penalties in 2015 by keeping within the limit of four power units per season.

By doing so, Mercedes has been forced into extending the milage of its engines, with a failure for Rosberg at the Italian Grand Prix in September having a knock-on effect at the end of the season.

Rosberg therefore arrives in Abu Dhabi with an engine down on power that makes him wary of his chances despite leading practice on Friday.

“It’s been a good start here in Abu Dhabi, but it will be a tough weekend for me as I have quite a high mileage engine in my car,” Rosberg said.

“After the Monza problem, we have had to stretch the engine life more than we had planned over the 19 races, so I definitely have a small lack of power on the straights and therefore need to make up extra time in the corners.

“It will be a big battle with Lewis here. He didn’t really bring together his quick laps, so it will be even closer tomorrow I’m sure. I’m looking forward to it and I definitely want to win this race and give the boys in the garage a reason to celebrate at the end of the season.”

On the other side of the Mercedes garage, world champion Lewis Hamilton was left unhappy with Mercedes’ long-run pace in practice, believing that there is ground to be made up.

“The long run pace doesn’t feel quite as strong so that’s something I need to work on,” Hamilton said. “I’ll probably make some more tweaks tonight and hopefully tomorrow it will be better.

“It’s very hard to overtake here, so of course it’s better to be up on pole. But that doesn’t mean it’s impossible to win from further back.”

Renault: Lotus announcement “very likely” next week

Renault Formula 1 chief Cyril Abiteboul has said that the French manufacturer expects to make an announcement regarding its pending takeover of Lotus next week.

Renault has been engaged in negotiations with Lotus over a takeover of the team for many months, and signed a letter of intent back in September confirming its plans to revive a works F1 operation at Enstone.

Although a deal is still yet to be formally agreed and announced, Renault employees have already started working at Lotus to lay the foundations for 2016.

It was speculated that Renault may announce its takeover of Lotus during the Abu Dhabi Grand Prix weekend, but Abiteboul confirmed on Friday that nothing would be made official at Yas Marina.

The Frenchman remained coy when asked what exactly Renault’s involvement in F1 would entail in 2016, saying: “I’m afraid I can’t answer to that question. I would like to be in a position to be able to answer to that questions, but I am not today.”

Despite there being no announcement in Abu Dhabi, Abiteboul said that he envisages one being made next week following the conclusion of the 2015 season.

“What I can say is that there will be no announcement regarding Renault’s future – short-term or middle-term future – over the weekend, but there will be an announcement, very likely, in the course of next week,” he said.

“We have always said that we would like to do that after the season. The season is ending on Sunday, around the start of December and that is what we will do stick to that plan, which is to make an announcement then.”

Abiteboul said that every effort was being made to finalize the deal with Lotus, but he is excited about the prospect of Renault returning to F1 with a works team for the first time since 2010.

“It’s fair to say that there is a process going on since the signing of the letter of interest on the 28th of September, there is a process involving a lot of people,” Abiteboul said.

“I think 50 people have been working night and day on the realisation of a possible acquisition of a majority stake in Lotus. It’s just a project, It’s been a proper rollercoaster, very exciting.”

Sebastian Vettel and Kimi Raikkonen both live life at high-speed racing in Formula 1, but how would they get on when faced with the fastest rollercoaster in the world?

To celebrate the fifth birthday of Ferrari World Abu Dhabi, Vettel and Raikkonen took on the Formula Rossa rollercoaster alongside reserve driver Esteban Gutierrez and other members of the Ferrari team.

Raikkonen is known for being the ‘Iceman’ and showing little emotion, and this was true even at the fastest points of the rollercoaster ride as he kept a straight face while Vettel raised his arms and whooped with excitement.

Never change, Kimi…

Alonso: Tough year with McLaren “necessary”

Fernando Alonso believes that his tough 2015 Formula 1 campaign with McLaren was a “necessary” stage within his racing career.

Alonso left Ferrari at the end of 2014 after five seasons with the Italian marque to rejoin McLaren ahead of its new partnership with Japanese manufacturer Honda.

McLaren-Honda enjoyed immense success in the late 1980s and early 1990s, but 2015 has proven to be a stark juxtaposition thanks to numerous problems with the power unit.

The issues have limited Alonso to just two top-ten finishes in 2015, yielding 11 points to leave him a lowly 17th in the drivers’ championships.

However, the Spaniard was upbeat when reflecting on the season in spite of McLaren’s troubles, believing it to be an important stepping stone.

“Well, tough year, obviously difficult and struggling with the pace all year and the reliability, so definitely a difficult season for us,” Alonso conceded.

“But personally I think it was necessary. It was a step forward in my career after the two championships, after five fantastic seasons fighting for the world championship but arriving second, so I needed some new motivation, some new project that I could trust and I could believe is the only way to become champion again.

“After one difficult season, as I said, I learn so much. I enjoy working with McLaren, with Honda, with all the Japanese discipline and Japanese culture into the team.

“I still remain very positive. I’m very, very happy and looking forward to next year being a little bit easier than this one that, as I said, has been difficult in terms of results.”

Looking ahead to 2016, Alonso expects McLaren to make progress and move up the grid, but is unsure whether it will make enough of a leap forward to challenge for race wins once again.

“At the moment there’s a question mark, I guess, where McLaren-Honda can be next year,” Alonso said.

“There are a lot of expectations in the team. I think we worked really all season, being united in some difficult moments and always moving forward, so I think for 2016 the main goal for the team is to come back to where we belong, we think, and being competitive, fighting for the top positions.

“I don’t know if that means fighting for the championship, I don’t know if that means fighting for victories of just being on the podium sometimes, that’s always difficult to know in a very complex sport like Formula One.

“There are definitely some big challenges ahead in this winter and I see all the things that the team has done in the last couple of months and these seem very logical, very positive and I’m confident that it’s going to be a completely different season next year and I’m happy with the progress.”
