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.

Hamilton has considered quitting F1, but now ‘loving it more than ever’

Leave a comment

Lewis Hamilton has revealed he considered quitting Formula 1 in order to pursue interests outside of the sport, but currently has no plans to retire, saying he is “loving it more than ever”.

Hamilton, 32, is currently fighting for his fourth drivers’ title against Ferrari’s Sebastian Vettel, and leads the championship by 28 points with six races remaining.

The Briton enjoys a celebrity profile outside of the sport unmatched by any of his peers, and has interests in fashion and music that he has long expressed a desire in pursuing once his racing career has finished.

After winning last weekend’s Singapore Grand Prix, Hamilton returned to Europe to attend the fashion week events in London and Milan before jetting to Malaysia next week to continue his championship bid.

Appearing on UK chatshow The Jonathan Ross Show, Hamilton discussed his future plans and admitted he had considered turning his back on F1 in the past.

“You try and go as long as you can. It’s not a sport you can go back to,” Hamilton said.

“When you’re in Formula 1, you’re in the spotlight, you’re at the top of the world – then it’s downhill from there on.

“You don’t earn the same money, there’s not a huge amount of opportunities because you’ve been in that world for so long. I’ve been there since I was eight.

“For me at the moment, for these past five, six years I’ve really been trying to work on what I enjoy outside of the sport so that when I stop I can walk away and still have other things.”

When asked directly if he was planning to retire soon, Hamilton said: “No. There have been talks about it, and I definitely have thought about it.

“There have definitely been times when I’ve thought there are other things I want to do, but then we’re in the heat of this battle right now and I’m loving it more than ever.

“The training, all the work that you put into something, and then you get to really show your abilities, it’s the greatest feeling ever.

“So I’m going to keep going for as long as I can and see what I can do.”

Hamilton existing contract with Mercedes expires at the end of the 2018 season, the Briton having made his F1 debut back in 2007.

Rossi expecting to ‘suffer’ with injury in MotoGP Aragon race

Valentino Rossi is expecting to “suffer” in Sunday’s MotoGP race at Motorland Aragon as he competes just 23 days after suffering a double leg-break in a training accident.

Rossi was forced to miss the last race at Misano due to the injury and was expected to miss the Aragon Grand Prix, only to make a shock return and be cleared by MotoGP’s medical staff on Thursday.

Rossi qualified a remarkable third on Saturday for Yamaha, less than two-tenths of a second behind pole-sitting teammate Maverick Viñales, surprising himself in the process.

“It’s a surprise for me and us, because I didn’t know what to expect,” Rossi said.

“A week ago I started to think maybe it was possible to ride here, and I did some laps with the R1 [bike] thinking it could be possible but with some pain. But the leg has improved every day.

“My position on the bike isn’t perfect but quite close to the normal one, at first we changed some things but now I’m using the normal footpeg and seat position and for sure it’s better.”

Despite impressing in qualifying, Rossi is less hopeful of his chances across a race distance, but is ready to give his all in the race.

“We still need to work a bit because with the race tire my pace isn’t fantastic but we’ll try,” Rossi said.

“On Friday morning when I woke up I was in pain, then this morning when I woke up it was better. So if tomorrow continues in the same way, I can do the race.

“But the bike is a bit more demanding on the race tires. For sure I have to suffer, but I’ll try.”

Ricciardo confident Red Bull hasn’t missed last F1 win chance in 2017

Red Bull Formula 1 driver Daniel Ricciardo is confident the team has not missed its last chance to win a race in 2017 after losing out to Mercedes’ Lewis Hamilton in Singapore.

Red Bull ran strongly throughout the Singapore race weekend, with Ricciardo boldly stating the team would win after qualifying third for the race.

A wet-dry affair marred by a start-line crash allowed Hamilton to sweep from fifth to first, while Ricciardo was left to settle for P2 for the third straight year in Singapore.

With none of the remaining circuits appearing to suit Red Bull’s RB13 car as well as Singapore, Ferrari and Mercedes are expected to share the spoils through the final six races of the year.

However, Ricciardo is sure that Red Bull will get another opportunity to add to its surprise victory in Baku earlier this season, which came about in surprising circumstances.

“Malaysia, obviously there were a few incidents last year but I think our general pace wasn’t too bad so we might be stronger than we think there,” Ricciardo said, looking ahead to next weekend’s race in Kuala Lumpur.

“Malaysia, Japan and then we’ll see. I think we can be podium cars, probably Malaysia, Japan, Austin.

“We might need some alternate conditions to really give us raw pace to fight for a win.

“I’m not going to sit here and say we’re not going to win one.

“I believe we’ll get at least one chance somewhere.”

F1 teams allowed to use current-year cars for demos from 2018

Formula 1 teams will be allowed to use their latest-spec cars at demonstrations organized by the sport from 2018, the FIA has confirmed.

F1 hit the streets of London, England ahead of the British Grand Prix in July for a live demonstration that attracted a crowd of over 100,000 fans.

Due to restrictions on the use of current cars outside of official testing and grand prix weekends, all teams were required to appear with older chassis models in London, most coming from 2015, the most recent year allowed to be used freely.

The restrictions meant that Haas, which only became an F1 team in 2016, could not field a car at all in London.

As part of the updated sporting regulations approved by the World Motor Sport Council and issued by the FIA earlier this week, a rule tweak was confirmed to let teams use their current-year cars at “demonstration events organized by the Commercial Rights Holder”.

Teams are still allowed to complete two filming day events with their current cars, with the majority opting to use one prior to pre-season testing to act as a shakedown of their new models.

While no further demonstrations such as the one in London have been confirmed by F1 yet, they are understood to be in the works after the success the July event enjoyed.
