How Mercedes’ tire strategy derailed them in Barcelona

Leave a comment

All the talk after the Spanish GP was, once again, dominated by tires. The grumbles in certain areas of the paddock are becoming louder and louder as race strategies were again decided by a team’s ability to make a set of Pirellis last long enough to complete a sensible stint.

Certain teams are better at this than others and, at the end of the day, it could be said that it’s a result of them doing a better job than the ones who struggle. A Formula One team’s job, after all, is to design a car to meet the challenges of the sport in its current form. It has to be said that the loudest complainers are noticeably the ones not finding things easy right now.

With that in mind I’ll take a quick look at two differing ends of that spectrum from Sunday’s race.

Race strategies are complicated things to plan; many factors that go in to making the decision and even once the decision’s made, it has to be flexible to cope with the unpredictable parameters.

Mercedes have a car, evident from the last three races, capable of being faster than anyone else over a single lap in qualifying and indeed that’s exactly what they were on Saturday.

Planning a race strategy from pole position’s a different prospect to planning one from further down the field and should clearly be a huge advantage at a circuit where overtaking is difficult. Assuming a good start, the driver in front should be able to dictate the race to a certain extent and pole sitter Nico Rosberg, starting along with all of the other front runners on the medium compound tire, did indeed get away in front.

His biggest problem, and one that came as no surprise to all involved, is the fact that the Mercedes F1W04 destroys tires considerably quicker than everyone else. On Saturday evening when the drivers and their engineers at the team, and indeed all of the teams, sat down to figure out their best strategic options, they knew this and had to factor it into their race plans.

The white walled medium compound tire, faster of the two but less durable, was the one to qualify on, but on a Mercedes it was never going to last very long in race conditions. At the start every car’s carrying close to 150kgs of fuel and that significant extra weight, combined with a track not yet at it’s most grippy and the need to fight other cars at close quarters, has a dramatic impact on tire life and therefore race strategy.

Hamilton: Mercedes has “a lot of work to do”

Their plan was, in all honesty, a damage limitation one, staying on the medium tire for as long as they could manage while holding off the field at the front and then using the harder compound for the remainder of the GP. Initial calculations had a three-stop strategy completing the race distance about 6 or 7 seconds faster than a four-stop one and so was optimal, but it would all depend on drivers looking after the rubber to make that work. Rosberg opted for the 3 stopper of medium/hard/hard/hard, but with the only way to make the hard compound last was for him to drive at a pace so slow he became a sitting duck. He predictably fell back through the field. Perhaps a four-stop race might have helped him a little, but in truth he was never going to catch the car in front and did just about survive the challenge of Paul Di Resta behind, so the outcome would probably have remained unchanged.

The eventual race winner, Fernando Alonso, who began the race fifth, would have had to look at things slightly differently on Saturday evening to Nico Rosberg. Also having to begin the race on medium compound tires, his optimal strategy relied on a great start, something Ferrari are generally able to rely on at the moment and duly delivered.

I thought their initial plan was to three stop, probably medium/hard/hard/hard or medium/hard/hard/medium, as the the car in the last stint of the race would cope a little easier on a set of medium tires and theoretically be faster.

In the end the Ferrari, with a handful of updates for this event, was able to push at a good pace and still keep the tires in good condition for most of the GP, in direct contrast to the Mercedes. This, combined with his stunning first lap, enabled to team to switch to a more comfortable four-stop race, allowing Alonso to push hard in each stint on a medium/hard/hard/medium/hard plan and stay ahead of the struggling pack. Again the two early spells on hards allowed the fuel load to burn off and the track to rubber in, before using mediums to set some blistering laptimes and secure his position out in front. By the time the final stop came around, the only set the team had left were already used from earlier in the weekend and so, with his position fairly stable, a set of hards saw him comfortably to the end. The stop actually came two laps earlier than planned because of a suspected, and now confirmed, slow puncture, but the hard work early on ensured it didn’t cost him track position. It was a superb drive by Alonso and ensured the team had options to play with when it came to deciding how to see out the race. They weren’t forced into anything or have to react to anyone else and so could use the four stop strategy to good advantage, pushing all the way.

To win from fifth position is unprecedented at this circuit and, while perhaps a sign of the Pirelli era, it’s actually more a sign of how badly the problems are at Mercedes. Their two cars, in P1 and P2 on the grid, finished in sixth and 12th, freeing up easy places for those further back and Alonso and Ferrari made great use of their start, racecraft and ultimately their race strategy, to take a dominant, flat out victory.

Magnus brings in ‘hired gun’ Spencer Pumpelly for Mid-Ohio

With Mansfield, Ohio the home of the prison in The Shawshank Redemption in the Ohio State Reformatory (also known as the Mansfield Reformatory) and with Magnus Racing PR ace and “Dinner with Racers” co-creator Sean Heckman one of two who’ve coined the inside joke that Spencer Pumpelly allegedly tried to kill a guy, it was only natural that Pumpelly will play the role of Magnus Racing’s “hired gun” near the prison at the Mid-Ohio Sports Car Course for Pirelli World Challenge competition this weekend.

The joke stems from the first season of “DWR” and was a running joke throughout the season. The “hired gun” play-on-words riffs on the fact Pumpelly will be substituting for Pierre Kaffer in the team’s No. 4 Audi R8 LMS this weekend, with Kaffer on duty at the Total 24 Hours of Spa-Francorchamps for Audi Sport.

Pumpelly has raced alongside Kaffer and Dane Cameron in PWC SprintX competition this season – Pumpelly and Cameron actually won the second race of the weekend at Lime Rock Park – and now the veteran sports car driver and Atlanta native will make his first PWC Sprint starts of the year, and first since his similar fill-in role with Heckman’s “DWR” co-creator, Ryan Eversley, at RealTime Racing last year… which also started at Mid-Ohio.

“It’s great to have Spencer back in the team,” stated Magnus Racing team owner and driver John Potter, who is in the team’s No. 44 Audi in GTA. “Spencer has always fit right in with us, but driving the team to our first series victory of course sealed a very special place for his legacy with us. We’re hoping Mid-Ohio suits both Spencer and the No. 4, and hopefully we can repeat the same feat.”

“It’s great to return to the team,” stated Pumpelly. “Obviously our last race together went extraordinarily well, and we’re hoping that same momentum can continue in to Mid Ohio. It’s always tough to say what to expect, especially in these very frantic sprint races, but we’re optimistic that the circuit should suit us. The entire team at Magnus has done a great job putting this effort together, and we look forward to pushing for additional results.”

Jay Frye expresses positive outlook on 2018 car

In a teleconference with members of the media on Monday, the prevailing mindset of INDYCAR President of Competition and Operations Jay Frye, who helped oversee the design of the 2018 universal aero kit (pictured above in a Chevrolet livery), was one of positivity following it’s official unveiling, in speedway trim, earlier today.

First and foremost, though he helped head the effort, he was vocal about the input he got from a number of different entities during the process of creating the design.

“This has been a year and a half in the making, and the process has finally come to a point where we can get the car on the track, so we’re quite excited about that,” he revealed. “We certainly appreciate everyone’s help, from Dallara to the teams who have helped to the manufacturers who have helped and certainly the fans. Over the last few months we kept putting out some different things to get reactions from fans to see what they thought of the project. It helped us a lot, because it made us feel like we were going in the right direction, which is great.”

The overall timeline of the project dates back to last year, particularly at tests at Phoenix International Raceway and Mid-Ohio Sports Car Course, where the experimentation process began. It was after those tests, as Frye explained, that the 2018 car began to take shape. “From that point (after tests at Phoenix and Mid-Ohio), we took what we thought the car should look like, and that’s where we talked about reverse engineering the car and to aesthetically make it have a historical feel, but in a very forward car, and I think we’ve done that.”

And with the project now open for the public to see, Frye appears confident that people will like how it performs. “The numbers have come back very strong, which we’re quite excited about. And here we are coming up to tomorrow, where we’re going to have our first on-track test. It’s been a long process, but it’s been very methodical,” he added.

Specific to those numbers, two obvious areas stand out the most: cost and downforce. First, as Frye explained, the operating cost of the 2018 aero kit is expected to be considerably less in comparison to the current aero kits from Chevrolet and Honda. Further, the conversion costs, the money the teams will spend in switching their chassis over to the new kits, is less than expected, making the package significantly more economical. As Frye explained, this is a result of negotiations in which it was agreed that this package will be in use for at least three years.

“From a total cost perspective, one of the things we looked at is called a conversion cost. What would it cost to convert the cars now? It’s not as much as we first thought it would be,” Frye detailed. “The annual cost will be 30-40 percent less than what the current car is. One of the things with having a universal car is we were able to negotiate the term, which is for three years, so the teams can plan for it. That was something that was very important: what the conversion cost was going to be and what the annual cost was going to be over this term.”

And, in terms of downforce, there will be reductions in aerodynamic downforce as well as overall downforce. First, most of the car’s grip will be generated from the bottom of the car, whereas currently most of the grip is produced by airflow over the top of the car. As Frye explained, this not only is significant to the overall performance of the car and how it will race, but it also reduces the chance for large debris fields after an accident.

“Sixty to seventy percent of the downforce is generated from the bottom of the car, where as before it was 40-45 percent, so there’s been a big gain in that. Also, another piece to the puzzle, there are less parts and pieces on top of the car, which creates less debris opportunities,” said Frye.

Further, the overall package is expected to produce 20-25 percent less downforce, that estimation even accounting for teams’ ability to develop the chassis to find areas where downforce could be added.

Frye added that this was a key element in the design of the car. “What we tried to do is create a window, so the total potential window of the car’s downforce level has shifted down. Obviously, as the teams start running the car, they’ll get better and better and better, so we wanted to make sure to move it a different direction that, once downforce comes back to a degree, we haven’t exceeded this window we’re looking at,” he revealed.

And, of course, enhanced safety was a big factor as well. Frye discussed a particular emphasis on side impacts, especially in the wake of accidents involving James Hinchcliffe (2015) and Sebastien Bourdais (2017), in which they suffered serious injuries following side-on impacts with the wall.

“The side-impact piece that’s in this car is moved forward, the radiator is moved forward, so it’s also a much more robust protection piece for the side-impact of the drivers,” Frye described.

And, of particular note in the wake of the F1 Strategy Group revealing that a halo will be introduced in 2018, Frye added that cockpit protection remains at the forefront, and while nothing is set in stone at the moment, the new chassis has room for cockpit protection to be added.

“The cars are built and designed around having some sort of application like that,” Frye said of cockpit protections. “At some point, we’ll test something, whatever application we can come up with. We’re definitely conscious of it, we’re conscious of how it will affect aesthetically, we’re conscious of the safety piece.”

The Verizon IndyCar series will test the 2018 car at the Indianapolis Motor Speedway tomorrow, with Juan Pablo Montoya and Oriol Servia doing the driving, with additional tests scheduled for Iowa Speedway, Mid-Ohio Sports Car Course, and Sebring International Raceway later this year.

Soon after series testing is complete, Honda and Chevrolet will begin receiving chassis for their respective teams to test, with all IndyCar teams scheduled to receive their cars beginning in November. Individual team testing will then begin in January of 2018.

Mercedes will join the FIA Formula E championship from the start of its sixth season in 2019 after taking up its option on an entry.

Mercedes announced last October that it had secured an option to join the grid as a manufacturer from season five (2018/19), but was still evaluating an entry as of last month.

Despite having until October to make a final decision on taking up the entry, Mercedes announced on Monday that it would be going ahead with plans to join Formula E, starting from season six (2019/20).

As part of a realignment of its motorsport interests, Mercedes also confirmed that it would be quitting DTM, Germany’s leading touring car series, at the end of 2018.

“Mercedes Benz has announced a strategic repositioning of its motorsport activities: the company will conclude its participation in DTM at the end of 2018 and enter Formula E in the 2019/20 season,” a statement reads.

“This new approach will see Mercedes-Benz competing at both ends of the motorsport spectrum: in Formula 1, the pinnacle of motorsport combining high technology and the most demanding competitive challenge; and in Formula E, which embodies the transformation that is underway in the automotive industry.”

“Mercedes-Benz will market future battery powered electric vehicles using the EQ label,” said Dr. Jens Thiemer, Vice President Marketing Mercedes-Benz.

“Formula E is a significant step in order to demonstrate the performance of our attractive battery powered electric vehicles, as well as giving an emotional spin to our EQ technology brand through motorsport and marketing.”

Mercedes head of motorsport Toto Wolff added: “In motorsport like in every other area, we want to be the benchmark in the premium segment and to explore innovative new projects.

“The combination of Formula 1 and Formula E delivers that. Formula E is like an exciting start-up venture: it offers a brand new format, combining racing with a strong event character, in order to promote current and future technologies.

“Electrification is happening in the road car world and Formula E offers manufacturers an interesting platform to bring this technology to a new audience – and to do so with a completely new kind of racing, different to any other series.

“I am pleased that we were able to extend our entry option for one year to the 2019/20 season. This gives us time to properly understand the series and to prepare for our entry in the right way.”

“Today is a great day as we welcome Mercedes to the Formula E family – adding to the increasing number of manufacturers joining the electric revolution,” Formula E CEO Alejandro Agag said.

“This step shows how much the world is changing, not only in motorsport, but the whole automotive industry. We’re witnessing a transformation that will first change our cities, and then our roads.

“Formula E is the championship that embodies that change, and together with all our teams and manufacturers we’ll keep pushing for technologies to have better and more affordable electric cars.”
