Virginia Tech playing key role in developing better racing tires for Goodyear, others

Leave a comment

Regardless of several tire issues that occurred in Sunday’s Auto Club 500 in Fontana, Calif., Goodyear never stops trying to improve upon the tires NASCAR cars ride upon in races.

Even if it means going back to school, so to speak.

The types of Goodyear tires that will carry the Sprint Cup cars and Camping World trucks in this weekend’s races at Martinsville Speedway will have gone through extensive testing in a new one-year old program at the National Tire Research Center, a program overseen by Virginia Tech University and its affiliated Virginia Tech Transportation Institute.

Goodyear Racing, NASCAR’s official race tire supplier, has quickly become one of NTRC’s biggest customers and proponents.

“Shortly after we opened for business last year, we established a very busy test schedule with Goodyear Racing, and we are excited to be a part of their massive effort to supply NASCAR with the best tires possible for each and every race,” NTRC executive director Frank Della Pia said in a story by Virginia Tech’s news service.

Instead of testing tires on vehicles, the NTRC simulates various conditions on a high-tech machine known as a LTRe. The 14-ton machine, which costs more than $11 million, is the only one of its kind anywhere.

It’s task is simple: to turn, rotate and spin tires up to 200 mph, which is right in the wheelhouse of tires NASCAR uses at high-speed tracks such as Daytona, Texas, Atlanta and Talladega (see video below).

But it also can mimic virtually any type of racing or road surface in the world that tires ride upon, from asphalt to dirt.

The testing involves a variety of conditions, weight and other forms of loads, forces (such as G-forces), and even one of the favorite things NASCAR crew chiefs like to play with: camber (the angle of the tires, particularly those in front).

“The racing teams and series that test with us are satisfied with our equipment and the knowledge and support from our staff,” Della Pia said. “The on-track results prove our ability, and the fact that our clients travel here to Southern Virginia from all over the world to be repeat customers speaks for itself.”

The NTRC is knee-deep in racing country. It’s adjacent to Virginia International Raceway in Alton, Va., a quick burnout from South Boston (Va.) Speedway, an hour away from Martinsville, two hours from Richmond and three hours from Charlotte.

The Center, which also does extensive work with partner General Motors, has grown exponentially in its first year of existence, and has even greater expansion plans over the next year-plus. It plans to hire more employees and eventually operate three daily shifts, as well as bring in other new machines to increase its testing capabilities.

“We are just getting started,” said NTRC president Tom Dingus. “We are building on the 65-year history of the Martinsville Speedway and the recent reemergence of the Virginia International Raceway.”

Nico Rosberg closed out practice for the Abu Dhabi Grand Prix at the top of the timesheets after edging out Mercedes teammate Lewis Hamilton on Saturday afternoon at the Yas Marina Circuit.

Rosberg arrived in Abu Dhabi for the final race of the 2015 Formula 1 season chasing a third successive victory, and appears to be in the box seat ahead of qualifying later today after setting the pace in both FP2 and FP3.

A fastest lap time of 1:41.856 was enough to give Rosberg P1 by almost three-tenths of a second in FP3 as Mercedes teammate Lewis Hamilton struggled to put together a clean flying lap, suffering two minor offs at the hairpin in the first sector.

Ferrari showed signs of an increased threat to Mercedes in FP3 as Sebastian Vettel finished just 0.040 seconds behind Hamilton in third place, bouncing back from a quiet Friday for the Italian marque.

Sergio Perez produced a fine flying lap to finish the session fourth for Force India, and his pace was underpinned by that of teammate Nico Hulkenberg in seventh as they were split by Kimi Raikkonen and Daniel Ricciardo.

Felipe Massa and Valtteri Bottas had another routine session en route to eighth and ninth for Williams, while Carlos Sainz Jr. made up for his stoppage on Friday by rounding out the top ten for Toro Rosso.

McLaren’s hopes of some points to finish the season were boosted once again in FP3 as Jenson Button finished 11th. Teammate Fernando Alonso was less fortunate, though, complaining of traffic on his way to 16th overall.

Pastor Maldonado and Felipe Nasr followed Button in P12 and P13, with Max Verstappen and Romain Grosjean finishing just behind. Marcus Ericsson had another difficult session, finishing 17th ahead only of the Manor drivers and Daniil Kvyat, who failed to post a lap time due to an electrical issue on his car.

Qualifying for the Abu Dhabi Grand Prix is live on CNBC from 8am ET on Saturday.

Rosberg wary of engine power deficit in Abu Dhabi

Nico Rosberg is anticipating a tough weekend in Abu Dhabi due to a deficit in engine power caused by the high mileage on his current unit.

Rosberg and the Mercedes team have managed to avoid any engine-related grid penalties in 2015 by keeping within the limit of four power units per season.

By doing so, Mercedes has been forced into extending the milage of its engines, with a failure for Rosberg at the Italian Grand Prix in September having a knock-on effect at the end of the season.

Rosberg therefore arrives in Abu Dhabi with an engine down on power that makes him wary of his chances despite leading practice on Friday.

“It’s been a good start here in Abu Dhabi, but it will be a tough weekend for me as I have quite a high mileage engine in my car,” Rosberg said.

“After the Monza problem, we have had to stretch the engine life more than we had planned over the 19 races, so I definitely have a small lack of power on the straights and therefore need to make up extra time in the corners.

“It will be a big battle with Lewis here. He didn’t really bring together his quick laps, so it will be even closer tomorrow I’m sure. I’m looking forward to it and I definitely want to win this race and give the boys in the garage a reason to celebrate at the end of the season.”

On the other side of the Mercedes garage, world champion Lewis Hamilton was left unhappy with Mercedes’ long-run pace in practice, believing that there is ground to be made up.

“The long run pace doesn’t feel quite as strong so that’s something I need to work on,” Hamilton said. “I’ll probably make some more tweaks tonight and hopefully tomorrow it will be better.

“It’s very hard to overtake here, so of course it’s better to be up on pole. But that doesn’t mean it’s impossible to win from further back.”

Renault: Lotus announcement “very likely” next week

Renault Formula 1 chief Cyril Abiteboul has said that the French manufacturer expects to make an announcement regarding its pending takeover of Lotus next week.

Renault has been engaged in negotiations with Lotus over a takeover of the team for many months, and signed a letter of intent back in September confirming its plans to revive a works F1 operation at Enstone.

Although a deal is still yet to be formally agreed and announced, Renault employees have already started working at Lotus to lay the foundations for 2016.

It was speculated that Renault may announce its takeover of Lotus during the Abu Dhabi Grand Prix weekend, but Abiteboul confirmed on Friday that nothing would be made official at Yas Marina.

The Frenchman remained coy when asked what exactly Renault’s involvement in F1 would entail in 2016, saying: “I’m afraid I can’t answer to that question. I would like to be in a position to be able to answer to that questions, but I am not today.”

Despite there being no announcement in Abu Dhabi, Abiteboul said that he envisages one being made next week following the conclusion of the 2015 season.

“What I can say is that there will be no announcement regarding Renault’s future – short-term or middle-term future – over the weekend, but there will be an announcement, very likely, in the course of next week,” he said.

“We have always said that we would like to do that after the season. The season is ending on Sunday, around the start of December and that is what we will do stick to that plan, which is to make an announcement then.”

Abiteboul said that every effort was being made to finalize the deal with Lotus, but he is excited about the prospect of Renault returning to F1 with a works team for the first time since 2010.

“It’s fair to say that there is a process going on since the signing of the letter of interest on the 28th of September, there is a process involving a lot of people,” Abiteboul said.

“I think 50 people have been working night and day on the realisation of a possible acquisition of a majority stake in Lotus. It’s just a project, It’s been a proper rollercoaster, very exciting.”

Vettel, Raikkonen take on world’s fastest rollercoaster in Abu Dhabi (VIDEO)

Sebastian Vettel and Kimi Raikkonen both live life at high-speed racing in Formula 1, but how would they get on when faced with the fastest rollercoaster in the world?

To celebrate the fifth birthday of Ferrari World Abu Dhabi, Vettel and Raikkonen took on the Formula Rossa rollercoaster alongside reserve driver Esteban Gutierrez and other members of the Ferrari team.

Raikkonen is known for being the ‘Iceman’ and showing little emotion, and this was true even at the fastest points of the rollercoaster ride as he kept a straight face while Vettel raised his arms and whooped with excitement.

Never change, Kimi…
