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.

IndyCar 2015 Driver Review: Gabby Chaves

Gabby Chaves

MotorSportsTalk continues its run through the driver-by-driver field in the Verizon IndyCar Series. In 15th and the rookie-of-the-year for 2015, was Gabby Chaves.

Gabby Chaves, No. 98 Bryan Herta Autosport Honda

  • 2014: Indy Lights champion
  • 2015: 15th Place, Best Finish 9th, Best Start 12th, 0 Top-5, 2 Top-10, 31 Laps Led, 19.3 Avg. Start, 14.4 Avg. Finish

Some drivers finish better than their performances show. Some drivers have performances better than their results show. The latter statement applied to Gabby Chaves in his rookie year, in what was an impressive first season after making the step up from Indy Lights, which deservedly earned him rookie-of-the-year honors.

The best comparison I’d make for Gabby is of Josef Newgarden in 2012 with Sarah Fisher Hartman Racing, a first-year driver on a single-car, newish team to the series.

Chaves rarely dazzled in qualifying but that wasn’t his fault; he and engineer John Dick worked well together and Chaves recounted multiple times this year that a tweak here or tweak there, the wrong way, on the aero kit would send them down the wrong setup path.

Results in races didn’t measure up either but again that was through almost no fault of his own. The only time Chaves looked truly like a rookie was at St. Pete, when he had several collisions. Otherwise he was ahead of eventual winner James Hinchcliffe at NOLA before getting punted off, reliable through the month of May in Indianapolis, finally able to break through for a ninth place in Detroit race two, overachieving in Texas, 11th at Milwaukee after some great wheel-to-wheel racing with series winners and champions, and then phenomenal at Pocono as he was on course for a first career win or podium before late-race engine issues – his first DNF of the season.

For both Chaves and Herta, you’d love to see them together for another season, and the results and confidence for both parties will grow as a result. Those who’ve seen Newgarden’s rise over four years with Fisher and now CFH will note the long-term stability, and that’s what Chaves could do if he gets the time.

He planted the seed of being a great IndyCar driver, and he became pretty versatile during the year too with additional appearances in the DeltaWing prototype, a short-track midget and one of Herta’s Red Bull Global Rallycross cars. To boot, he’s a smart, great kid who is mature beyond his years, and someone you should be buying stock in now. Anyone who saw Chaves in the Mazda Road to Indy should not have been surprised by his rookie season in the big cars.

Having already taken you behind the scenes in Barcelona, Budapest, Singapore, Melbourne and Silverstone, Will Buxton and Jason Swales now head to one of Formula 1’s most iconic venues for the latest episode of Off The Grid.

Monza has appeared in all but one F1 season since the formation of the world championship in 1950, and is a firm favorite among drivers, teams and fans alike.

However, there is far more to the Italian Grand Prix than meets the eye, as we find out in Saturday’s premiere of Off The Grid: Monza at 9:30am ET (follows Russian GP qualifying).

Having honed his talents in go-karts as a kid, Red Bull driver Daniel Ricciardo is now trying to pass on his knowledge to the next generation of racers. But can he teach Will or Jason a thing or two?

We also catch up with Force India’s Nico Hulkenberg and get a feel for life on the road as he takes us for a tour of his lavish bus in which he travels in for the European F1 races.

Have you ever wondered just how the suits F1 drivers wear are made? We go behind the scenes at Alpine Stars’ factory in Italy and find out.

Off The Grid: Monza premieres on Saturday at 9:30am ET on NBCSN following Russian GP qualifying.
