NASCAR: New 2015 rules options go under the microscope at Michigan test

5 Comments

Yesterday Jeff Gordon rolled into victory lane at Michigan International Speedway, and today, several NASCAR teams are back at the track in what could be an important day for the 2015 NASCAR Sprint Cup Series season.

Aero, engine and tire adjustments are on the docket for today’s test. NASCAR is examining reducing more downforce, and Goodyear is expected to bring a stickier tire, per NASCAR.com.

“We have a prime rules package and also will be doing a low downforce package, because some of the drivers have been very vocal,” said Gene Stefanyshyn, vice president Innovation and Racing Development for NASCAR, via NASCAR.com.

Those testing include Jamie McMurray, Kasey Kahne, Danica Patrick, Paul Menard, Brad Keselowski, Ricky Stenhouse Jr., Aric Almirola, Denny Hamlin and either Clint Bowyer or Brian Vickers.

Here’s a couple early morning updates from NBCSN NASCAR AMERICA insider Nate Ryan, who is at the test:

Pirelli offers first public glimpse of wider F1 tires for 2017

Pirelli has revealed its new wider tire models for the 2017 Formula 1 season, harking back to the rubber used in the 1970s and 1980s.

As part of the overhaul being undertaken on the technical regulations for next year, Pirelli was asked to produce wider and more durable tires, and received 25 days of testing to prepare for their implementation.

At an event in Monaco on Saturday morning, Pirelli offered a public glimpse of the new tires for the first time, fitted to a show car.

The Italian supplier also released an accompanying video and statement explaining the changes.

“Pirelli has already begun track testing tires in the current size but with constructions and compounds for 2017, using cars that are two or three years old,” the statement read.

“From roughly the beginning of August, current or 2015 cars will be tested on track equipped with the first prototype F1 tires in the new size. And we’re talking about a considerable increase: the front tire grows from 245 to 305 millimeters wide (which is nearly the same width as the current rear) while the 2017 rear grows from 325 to 405 millimeters.

“The diameter stays more or less the same, with a slight increase from 660 millimeters to 670 millimeters (the same as the current rain tire diameter, except with a slick rather than patterned surface). The wheel size remains the same as it has always been: 13 inches, giving Formula 1 a unique look that it doesn’t yet want to renounce.

“Nonetheless, as a showcase of what is possible, Pirelli has already successfully demonstrated 18-inch tyres on track and remains open to investigating even larger sizes in future.

“In order to give an idea of the scope of the changes without getting too bogged down in mathematics, the front tire will become nearly 25% wider, while the rear tyre becomes more than 30% wider. There will be a corresponding increase in the tire footprint: the amount of tire that is physically in contact with the ground at any given point.

“This is where the extra grip comes from, enhancing each car’s ability to put its power down onto the ground, leading to more performance through corners as well as under acceleration and braking.”

Ferrari reserve driver Jean-Eric Vergne completed a test with the new compounds earlier this month at Fiorano using a 2014-spec car.

The Frenchman was impressed by Pirelli’s developments, telling NBC Sports that he thought 2017 would be “great” for F1 tires.

The wider tires will undoubtedly help F1’s drive to make the cars look more aggressive, while the additional grip will contribute to the multiple second gain in lap time that is coveted.

Tony Kanaan woos IMS after posting fastest Carb Day lap

“I think this track will pick the winner,” Tony Kanaan told reporters Friday after Carb Day practice was completed for the 100th Indianapolis 500 presented by PennGrade Motor Oil.

“So I’m trying to massage the track a little bit, talk to her nicely, and then see if she will pick me on Sunday.”

Kanaan certainly impressed the 2.5-mile ‘lady’ in practice, by posting a fastest lap of 226.280 mph that would seem to have her shunning all other suitors. Carlos Munoz set the second-fastest speed, but he was nearly a quarter of a second per lap slower with a speed of 224.772 mph.

Speeds were largely dependent on tows in the final tune-up for Sunday’s race.

All 33 drivers who qualified for the 100th running of the Indy 500 tried their dead-level best to impress the track. They raced side-by-side through the corners and filled the course with cars. For most of the session, a majority of the drivers were on course at the same time, and that surprised many.

“You should have asked me, I would have told you different,” Kanaan said.

“This is the closest we get to the race, two days, and after being here for almost a month, the engineers come up with different plans every day,” Kanaan added. “The more time you give them, the more they come up with stuff. And we had almost five days without being on track, so they go back to the shop and do simulations. So we had to test.”

Race conditions will be markedly different than what everyone faced in qualification and that is another reason so many cars were on track. It is also one reason Kanaan was so pleased with his time.

If a full field had not practiced, no one would truly know what they would face on Sunday. “Everybody is eager to feel how the car behaves in traffic. So it was a race out there today.”

Kanaan was pleased with the response he got from Indy.

“I’m happy with my car,” Kanaan said. “Obviously I have to pass 17 people before I get really happy with my car. But, you know, after the struggle in qualifying, we really focused on the race.”

Kanaan will start 18th, alongside Juan Pablo Montoya and close behind some other top-ranked drivers.

“One thing that eases my mind a little bit being back there, there are a lot of good guys back there with me,” Kanaan added. “You know, if you look around Montoya, Charlie Kimball, Scott Dixon, they’re very experienced guys back there, which sometimes it’s not the case.”

“So I really don’t have a plan. My plan is to start the race. If there is a gap, I’m going to go for it.”

Indy occasionally rewards spontaneity, so Kanaan’s fastest speed in final practice may be a strong indication of his odds of winning his second Indy 500. His first victory came in 2013.

When Townsend Bell and Mario Andretti made pizza (VIDEO)

Before the 100th Indianapolis 500 presented by PennGrade Motor Oil kicks off on Sunday, Townsend Bell and Mario Andretti tossed around a couple pizzas.

Bell, the NBCSN IndyCar analyst who starts fourth in the No. 29 California Pizza Kitchen/Robert Graham Honda, has easily his best shot to win the Indy 500 in his 10th attempt.

He’s part of the five-car Andretti Autosport armada along with Carlos Munoz, Marco Andretti, Ryan Hunter-Reay and Alexander Rossi.

Stoneman edges Jones in closest finish ever at IMS in Freedom 100 (VIDEO)

Leave a comment

INDIANAPOLIS – No words other than “wow” to summarize the immediate aftermath of the Indy Lights Presented by Cooper Tires’ Freedom 100 at Indianapolis Motor Speedway.

At a race that had two incredible photo finishes in 2013 and 2014, another one occurred Friday with Dean Stoneman edging Ed Jones by just 0.0024 of a second.

“As you can see on the screen now it was bloody close,” Stoneman said from Victory Lane after driving the No. 27 Stellrecht Dallara IL-15 Mazda for Andretti Autosport.

It’s the closest finish in Indianapolis Motor Speedway history with Stoneman having led the field to the green on the last lap, but lost the lead at Turn 1 when Jones around the outside, before Stoneman got past him through Turn 3 and stayed ahead.

The Andretti Autosport driver then edged the Carlin driver at the line, fist in the air for his second win at IMS in three weeks, after also winning on the Indianapolis Motor Speedway road course.

“It’s great. I was in a hospital bed five years ago dreaming to be racing here and winning now,” Stoneman added.

“First [win] ever here for this race,” said Michael Andretti, car owner. “We’re so excited. We’ve been trying so many years to win this and Dean finally brought it to us.”

“It’s so frustrating to lose the race like that,” said second-place finisher Jones. “We were back and forth throughout the race and all the time I was waiting behind Dean for those last few laps. He held up everyone really slowly on that restart and caught quite a few incidents.”

“I got the lead in turn one and I thought I had the good run and I was pulling away but he had the draft down the back straight and I made the decision to stay on the inside,” Jones added, “He got the momentum on the outside and he just beat me to the line. It was so close and the team did a fantastic job of giving me the car to win the race.”

“That minor mistake just cost me everything.”

Previous closest finishes were 0.0026 of 2013 when Peter Dempsey won, and 0.005 of a second when Gabby Chaves won.

In third place, Dalton Kellett scored a career-best result in the No. 28 K-LINE car for Andretti Autosport, with Shelby Blackstock and Scott Hargrove completing the top five finishers.
