Pirelli hasten changes after Ecclestone criticism

2 Comments

Pirelli will implement changes to their 2013-specification changes sooner than planned following criticism for Formula One boss Bernie Ecclestone.

Formula One’s official tire supplier announced on Tuesday it will bring revised compounds in time for the Canadian Grand Prix instead of the British Grand Prix, as they had previously indicated.

The changes to the tires aim to prevent drivers from needing to make four pit stops per race, as occurred in Spain, and to address the delamination problems that have been seen.

“Our aim is to provide the teams with a new range which mixes the stability of the 2012 tyres and the performance of the current ones,” said Pirelli motorsport director Paul Hembery.

“As a company, we have always moved quickly to make improvements where we see them to be necessary. After evaluating data from the first few races this year, we’ve decided to introduce a further evolution as it became clear at the Spanish Grand Prix that the number of pit stops was too high.”

“We’ve also taken this step to avoid the delaminations that were caused by track debris,” Hembery added.

“It’s important to point out that these delaminations, which occur when the tread comes off, do not compromise the safety of the tyres as the core structure of the tyre is not affected in any way, helping drivers to complete the lap and to change the damaged tyres safely. These delaminations were due to damage from debris that overheated the tread.”

Felipe Massa suffered two tire failures during the race in Bahrain, Lewis Hamilton had a tire problem during practice for the same race, and Paul di Resta had a similar failure during practice in Spain.

Ecclestone criticised Pirelli following the Spanish Grand Prix, which saw drivers make a total of 77 pit stops.

“The tyres are wrong, not what we intended when we asked Pirelli to produce something which did a half race,” Ecclestone told the Daily Express.

Starting lineup grid for IMSA Petit Le Mans: Tom Blomqvist puts MSR on pole position

IMSA WeatherTech SportsCar championship contender Tom Blomqvist put the Meyer Shank Racing Acura at the front of the starting lineup for the Motul Petit Le Mans at Michelin Road Atlanta.

Blomqvist turned a 1-minute, 8.55-second lap on the 2.54-mile circuit Friday to capture his third pole position for MSR this season. Earl Bamber qualified second in the No. 02 Cadillac for Chip Ganassi Racing.

Ricky Taylor was third in the No. 10 Acura of Wayne Taylor Racing, which enters Saturday’s season finale with a 19-point lead over the No. 60 of Blomqvist and Oliver Jarvis (who will be joined by Helio Castroneves) for the 10-hour race.

With the pole, MSR sliced the deficit to 14 points behind WTR, which will field the trio of Taylor, Filipe Albuquerque and Brendon Hartley in Saturday’s race.

“We really needed to put the car in this kind of position,” Blomqvist said. “It makes our life a little less stressful tomorrow. It would have given the No. 10 a bit more breathing space. It’s going to be a proper dogfight tomorrow. The guys gave me such a great car. It’s been fantastic this week so far, and it really came alive. I’m hugely thankful to the boys and girls at MSR for giving me the wagon today to execute my job.

“That was a big effort from me. I knew how important it was. It’s just awesome for the guys to give them some sort of reward as well. It’s always nice to be quick. If you do the pole, you know you’ve got a quick car.”

Though WTR has a series-leading four victories with the No. 10, MSR won the Rolex 24 at Daytona and has five runner-up finishes along with its three poles.

The strong performances of the ARX-05s ensure that an Acura will win the final championship in IMSA’s premier Daytona Prototype international (DPi) division, which is being rebranded as Grand Touring Prototype in the move to LMDh cars next season.

Taylor qualified third despite sliding into the Turn 5 gravel during the closing minutes of qualifying while pushing to gain points.

“Qualifying was important for points,” Taylor said. “Going into it, if we outqualified the No. 60 Meyer Shank Acura, they had a lot to lose in terms of championship points. So, we were trying to increase the gap over 20 points which would’ve made a big difference for tomorrow. We would have loved to get the pole and qualify ahead of the No. 60, but in the scheme of the points, it didn’t change a whole lot. I’m feeling good since it’s such a long race, and the No. 10 Konica Minolta Acura team does such a good job strategizing and putting us in a good position.

“I’m very confident in our lineup and our team compared to them over the course of 10 hours. I’d put my two teammates up against those guys any day. I think we are all feeling optimistic and strong for tomorrow.”

In other divisions, PR1 Mathiasen Motorsports (LMP2), Riley Motorsports (LMP3), VasserSullivan (GTD Pro) and Paul Miller Racing (GTD) captured pole positions.

The broadcast of the 10-hour race will begin Saturday at 12:10-3 p.m. ET on NBC, moving at 7 p.m. to USA Network. Peacock will have flag-to-flag coverage.
