Renewable fuel, guayule tires make this greenest St. Pete Grand Prix yet

Shirley Beal

ST. PETERSBURG — As IndyCar driver Romain Grosjean sped all around a California keep track of all through a exam previous month, he experienced to ask if his No. 28 Honda was using the series’ new 100% renewable race gasoline.

“It just felt the exact,” Grosjean reported.

IndyCar could not have asked for a far better endorsement of the sustainability initiative hovering about this weekend’s Firestone Grand Prix of St. Petersburg.

Sunday’s race will be the very first with Shell’s renewable gasoline, a blend partly manufactured from sugarcane scraps. Just about half the Firestone tires are greener thanks to rubber from an Arizona shrub.

If Grosjean and his colleagues didn’t observe either improve from the cockpit, neither will fans seeing downtown.

“That’s success,” IndyCar main of personnel Mark Sibla explained.

The Firestone tires are now a confirmed accomplishment IndyCar unveiled them at August’s race in downtown Nashville and documented no troubles in how they gripped the track or wore down. The only difference is the resource.

Most tires use purely natural rubber from hevea trees grown in southeast Asia. The product is flown to the U.S., processed and despatched to a tire manufacturing unit.

Rubber from the guayule (pronounced why-ooh-lee) plant is the very same chemically but has two simple pros, explained Cara Krstolic, Firestone’s government director of race tire engineering and generation. Since guayule grows effectively in the Southwest, Firestone can farm it domestically as a substitute of traveling it throughout the Pacific that shrinks the carbon footprint. And for the reason that the 2-foot desert shrub is resistant to warmth and drought, it employs only half the drinking water alfalfa or cotton fields would have required on the identical farm.

A decade’s worth of perform has authorized Firestone to substitute havea rubber with guayule rubber on a single aspect of the tire (the sidewalls) for the five sets of alternates each team will get this weekend.

“It’s the simplest place to start,” said Krstolic, also Firestone Racing’s chief race engineer. “Start there, and then we scale up from that point.”

Scaling up doesn’t only indicate expanding these alternates from one race previous 12 months to 5 this 12 months to a entire plan, or making an all-guayule tire. It indicates finding approaches to make each shrub produce additional rubber and encouraging extra farmers to expand it. When that takes place, Firestone can just take what it discovered in IndyCar and utilize it to the tires it will make for you to sit in site visitors on the Howard Frankland Bridge.

“Using that greatest proof issue of technological innovation to increase its use, to carry consciousness to it, that’s heading to be critical for us,” Krstolic reported.

Recognition is a very similar target for Shell and its renewable fuel.

Shell motorsports technological know-how supervisor Bassem Kheireddin is very pleased that a “significant” portion of the blend arrives from next-generation ethanol. The resource: Brazilian sugarcane leftovers that were being in no way likely to be made use of to feed people today or livestock.

“It’s the part that did not have a use in the previous now has been uncovered to be able to be transformed into a sugarcane ethanol,” Kheireddin stated.

Not just any sugarcane ethanol. Sugarcane ethanol that can assistance power a motor vehicle at 240 mph with 60% much less whole greenhouse gas emissions than fossil fuels — all while performing perfectly with IndyCar’s previous engines so no team experienced to modify a one portion.

“The motorsports for Shell, it’s a platform,” Kheireddin reported. “It’s a fantastic avenue to reveal and make broader consciousness of new technology that can assist boost sustainability.”

Bettering sustainability has become a important intention for IndyCar as a full for various motives. The world wide enthusiast survey it unveiled at past year’s Grand Prix confirmed youthful followers and 20% of feminine enthusiasts want the sequence to get greener. Corporate partners, like title sponsor NTT, are pushing for environmental awareness, much too.

“As a sport that is fueled by sponsorships and massive corporations, we’ve acquired to observe go well with,” explained NBC Sports activities analyst James Hinchcliffe, the 2013 Grand Prix winner.

Internally, Sibla claimed IndyCar would like to be a superior corporate citizen by becoming North America’s most sustainable motorsport series. That means obtaining techniques to reduce its carbon footprint without influencing some of the most competitive racing in the entire world.

A number of modifications are imperceptible to even the most rigorous followers. The series a short while ago changed its golf carts with an electric powered fleet. Beginning this weekend, each tractor trailer from IndyCar, its groups or sister corporation IMS Productions will generate to the monitor on R99 diesel, a renewable gasoline that slashes greenhouse fuel emissions up to 85%.

Other alterations are in the operates, as well, from the enhancement of hybrid engineering to battery-run tire guns on pit stops.

“I feel the crucial is, how can we introduce sustainable technologies, improvements, parts with no impression to the efficiency or the merchandise itself?” Sibla claimed. “I consider that’s what we’ve been capable to obtain definitely with equally of these chances, the one particular with Firestone and the 1 with Shell. You want a driver to stroll away and say, ‘I had no plan there was a transform,’ suitable?”
