Pirelli considering change in tire design

Leave a comment

Pirelli is reportedly considering a change in its tire design following a difficult set of practice sessions at the Spanish Grand Prix.

Paul di Resta suffered a heavy tire failure during FP2 which was investigated by Pirelli, and although they have put this down to debris on the track, it would appear that further concerns have been raised.

Pirelli’s F1 chief, Paul Hembery, has said that although the the tires are still safe to use, the frequency of failures does not aid the corporate image.

“We would like to find a way of changing that because it doesn’t look very good from an image point of view,” Hembery told Press Association.

“We would have to look at changing some parts of the structure, which is something we can do.”

However, Hembery said that any changes would have an impact on the teams, who would have to deal with the new tire design.

“We would need to balance that with what impact it might have on the teams because they have a lot of data that’s based on this year’s structure which influences aerodynamics.

“Also there is a lack of testing. Some of the solutions we might need would need some more extensive testing, so we are caught in between a bit of a rock and a hard place.

“But we do take these things seriously. We’re looking at it to see if we can change this mode of failure, the visibility of it and turn it into something that is less dramatic from a visual point of view.”

It appears that Pirelli may have finally bowed to pressure from the teams and fans to make a change to its tire design, which will please Red Bull in particular following their vocality over the matter.

Porsche ready for final LMP1 outing in Bahrain

At the conclusion of this weekend’s Six Hours of Bahrain, Porsche’s four-year run in the LMP1 class of the FIA World Endurance Championship will come to a close. The pair of Porsche 919 Hybrids will roll off from first and third after Friday’s qualifying, and will look to add one more win to their final tally.

Despite its short stint, Porsche more than made its mark on the class and the championship, immediately jumping to the fore and challenging young hotshots Toyota, race winners in 2012 and 2013 and LMP1 champions in 2014, and long-time stalwarts Audi, which introduced its first LMP1 entry in 1999 and quickly became the predominant force in the LMP category.

The 2014 season saw Porsche score four poles and a race win before embarking on a remarkable three-year stretch from 2015 to 2017, in which they scored three straight 24 Hours of Le Mans wins and three straight WEC driver and manufacturer championships (they wrapped the 2017 titles at the previous race in Shanghai.

Fritz Enzinger, Vice President of the LMP1 effort, detailed that the early days of the program were a little rocky, given the complex hybrid technology they were working with, but that they were able to find their stride relatively quickly.

“Back then (in 2014), we developed from zero a highly complex hybrid racecar on a Formula One level. The early days were extremely demanding, especially as we had to set up the infrastructure, including new buildings, at the same time, plus assembling a team of 260 excellent people. The timing was really tight and the 2014 Le Mans race came way too early for us. But since then, we have managed maximum success. I’m incredibly proud of this team and I hope that we can conclude the era of the Porsche 919 Hybrid with a good race in Bahrain.”

Team principal Andreas Seidl added that having the championships wrapped up will make the final weekend more enjoyable, as they won’t have the pressure of racing with the championships in mind.

“I feel a big relief that the pressure of defending the manufacturers’ and drivers’ world championship titles is resolved before our last race. The emotions of the farewell under the stress of the title battle would have been extremely hard for the team,” Seidl revealed.

Further, he added that Toyota’s TS050, which debuted last year, made their task all the more challenging as they worked to developed the Porsche 919 Hybrid –  the same basic car that they launched in 2014.

“In Toyota this year, we are facing a competitor who developed an all-new car for 2016. We, instead, kept developing our existing car. That we still won Le Mans as well as both championship titles is thanks to outstanding driver performances, many detailed improvements and the operational strength of our team,” Seidl asserted. “Now we have to get ourselves together and focus on this last race. We want to leave the stage not only as world champions but also with a performance that is satisfying for all of us. Six hours of reliability and faultless work are big challenges of men and machine. Safety has the highest priority. Only after the checkered flag can we allow our reflective feelings to break through.”

In terms of approaching Porsche’s LMP1 swan song, some drivers are taking different approaches. For example, Nick Tandy, driver of the No.1 entry with Neel Jani and André Lotterer, isn’t putting much thought into the farewell and is focusing entirely on the race.

“I prefer not to think about the farewell yet,” Tandy quipped. “The Bahrain race is very interesting anyway because we are racing from day into night. It is normally very hot for the car, the drivers and especially the tires. It is a challenging race to finish the season at. I haven’t been there since 2015 but I was on the podium back then when I came second in the LMP2 class. So this year’s target is to make it onto the LMP1 podium.”

Conversely, newly crowned champion Brendon Hartley, driver of the No. 2 entry with fellow champions Earl Bamber and Timo Bernhard, freely expressed his emotions about the end of the Porsche LMP1 program.

“Going to Bahrain will be emotional for all of us. Especially as we arrive as World Champions with less pressure now,” asserted Hartley, who has also endured a busy stretch since the Petit Le Mans on October 7 that has seen him racing every weekend across the WEC, Formula 1, and the IMSA WeatherTech SportsCar Championship. “I have so many incredible memories and experiences with the 919 Hybrid, teammates and all the boys and girls from the Porsche LMP Team. We shared something very special together. After developing the Porsche 919 for more than four years, it’s an absolute dream to drive so we will all be enjoying every last lap with this awesome machine. On one side there will be a lot of sadness, but on the other hand we will be giving everything to give this project the ultimate send off it deserves.”

Porsche’s LMP1 effort won races in each of its four seasons, totaling 17 victories between it’s entries.
