F1 Grand Prix of Belgium - Practice

McLaren, Jenson Button nearly made one-stop race work

Spa’s one of the greatest race tracks in the world and often produces some of the best races. It was still an amazing track on Sunday, but the race itself in Belgium may not go down in history as an all time great.

In terms of strategy, the teams this weekend had some difficult decisions to make for more than one reason.

Pirelli brought the two hardest dry compounds in their current range to this event and that brought with it a different set of challenges to those faced at some other circuits on the calendar. Degradation wasn’t so much of a concern, but the varying temperatures and conditions meant the goalposts for drivers and engineers trying to tune their cars or driving styles in order to switch-on the tires, was constantly moving.

With everybody setting their qualifying times on intermediate tires in mixed conditions, not only was the starting order shuffled, but the choice of Sunday’s starting compound became free in the dry. This opens up the possibility of various strategic options for everybody and calculations beforehand had a dry race being marginally faster using a two stopper than a one stop plan, albeit with not too much in it.

The major unknown variable of course, as is often the case here, would be the weather.

Almost everyone’s information said there would be rain today, no one could be confident of when or how much, but there had to be an element of flexibility factored into every strategy. That information, didn’t just affect teams on race day, but dictated the way they approached Saturday’s qualifying too.

This track has a long lap and two of its three sectors are very fast, long straights with high-speed turns. The middle sector is the opposite, tight, slow and twisty. There are different ways to approach the car setup, with either low or medium downforce levels helping for different parts of the lap, but whichever way you choose to go, there’s always a compromise to be made.

Lotus opted for a higher level of aerodynamic downforce than many of the other top teams, which helped them through sector two. In their case it was deemed to give them an overall laptime gain over being fast in the high speed sections, but losing out too much in the middle part of the lap. Red Bull, Mercedes and Ferrari all went the other way and set themselves up for a higher top speed.

Interestingly, the Red Bull, which traditionally isn’t the fastest in a straight line, came up with a low downforce package for this race that proved far more efficient than it’s rivals and it was that speed advantage which proved crucial to Sebastian’s victory.

In terms of tires, most of the leaders went with a similar medium/medium/hard strategy, which was the optimum, as everyone was in the unfamiliar position of entering the race with plenty of new sets available, having run much of the weekend in wet conditions.

The key for the eventual winner, as we’ve seen him do many times before, was to get past Hamilton early and break the DRS gap before the system was activated on lap 3. His extra top speed advantage enabled him to do just that and the aggressive move up the hill from Eau Rouge on lap one gave him the perfect opportunity. The dominance of the Red Bull at this circuit, a place where traditionally they haven’t gone well in the past, is an ominous sign for everyone else. Vettel was able to control the race with such ease, he was never out of the lead from that point on and was being reminded by his team as early as lap three to conserve the car.

Behind him, Hamilton faded with a car that simply wasn’t in the same league. The team got everything right in terms of their strategic options and probably got as much as they could from the weekend. Ferrari showed real promise here, a huge improvement after recent events, and Fernando was one of the biggest movers in the race. Good decisions on when to stop helped put him in a position to fight for positions and his great start meant he was Vettel’s closest challenger. However, the truth is that, try as he did, he had nothing left to close the gap that the triple world champion stretched out to seventeen seconds before backing off at the end of the race.

One of the more interesting strategic choices came from McLaren and Jenson Button. They decided to gamble on a one-stop race, hoping rain might play into their hands at some point. Although the rain never came, his pace was good, but he quickly realized that he couldn’t go far enough into the first stint to make the single stop work. The switch to a two stop plan still kept him firmly in the mix and he was running in the top six when it came to making the second stop. Having run mediums then hards, there was a moment when it may have been considered a worthwhile option to stay out and run to the end, but the team felt a long stint to the flag may have left him vulnerable towards the end.

It was probably  true, but had he managed to extend his early spell on mediums for another five or six laps, the option may’ve been a viable one. As it was, his second stop for hard tires dropped him back and although his pace was up there with the leaders, his track position left him with nothing more to fight for. Still, a far more positive weekend for the McLaren team.

The only one-stop strategy in the end came from Lotus and Romain Grosjean, but the high drag, high downforce setup left him unable to make up the ground he needed to and fighting in the middle of the pack cost him too much time in the end. He was another one who needed the intervention of rain to bring him back into play.

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.”
