Honda working on IndyCar engine fix following parts issue

0 Comments

ELKHART LAKE, Wis. – The blessing and curse of Honda Performance Development (HPD)’s improved performance and horsepower this year has been a tradeoff in the reliability department.

With now double digit failures over the last month or so, in Indianapolis and elsewhere, it’s been a season where reliability has become more of a story line than normal.

This has arisen though Honda’s on-track performance this year has seen the manufacturer deliver five wins (three more than in all of 2016) including the Indianapolis 500, with four of its five teams winning races thus far in nine races.

HPD President Art St. Cyr addressed both the failures and the recent successes Honda has achieved in the last month during a media availability Saturday at Road America, noting it was a parts processing issue that has contributed to some, if not all, failures.

“We had a couple engine failures over the last month or so,” St. Cyr said. “We have done a lot of analysis. It was actually pretty deep in our engine and the part that failed is one that we’ve been using for quite a while. Ultimately, it came down to a parts processing issue for that. So we have been able to identify the part that is failing.

“We have some fixes in place for the rest of this year. As it stands right now, we’re getting those parts into HPD at this point and we’re starting to build new engines with those parts in it. Unfortunately, the durability plan that we always had, going 2,500 miles, it’s going to take a while to cycle those engines into our pool.

“We hope to have those engines into our spares pool, optimistically by Iowa, but more realistically by Toronto.”

HPD does not plan to do a wholesale changeout of engines, St. Cyr intimated.

“There is no plan right now to a wholesale change out engines,” he said. “It happens in about one out of every eight engines, and if it does fail, it fails early. So when that problem arises, it shows up pretty quick.

“So, our expectations are that, once we get the engines in the spares pool, we will continue the engines that are in the cars throughout the remainder of their lives. And then those will be replaced with new engines.

“Knock on wood, hopefully we can get some of them in at Iowa, but more realistically, probably Toronto is when they’ll really start to show up.”

St. Cyr confirmed HPD has made a horsepower increase this year though would not be pressed on how much that increase has been.

“When you make more horsepower, you do expose parts to more stresses. That’s the fundamental thing about it,” he said.

“In this particular case, what it did was reduced our safety factor on that particular part. It still should have been fine, but the problem is that part of the process in the engine is the stress riser. It’s not in every engine, but it on a handful of engines.

“Yes, the increase in power is a contributing factor to that, because obviously there’s more stress on the engines, but the way the part if designed it should have been able to sustain that stress.”

He also said the company was happy with the tradeoff that has come with Takuma Sato’s win in the Indianapolis 500. That win made him a “popular winner” both in America and Japan as a result of his victory, helping both Honda arms.

“In general, our main goal is to win the Indy 500. We knew that, even if we ran the engines at full power, that the majority of our engines were going to make it,” St. Cyr explained.

“So, in that case, we were willing to make that tradeoff on that. If it was going to fail every engine, then maybe not, but ever circumstance is different. But, in this particular case, we were willing to make that.

“You risk that every year. Typically, both manufacturers have about two mechanical failure. That’s about what had this year anyway. We’ll make those judgments on a case-by-case basis.”

Heading into Road America this weekend for the KOHLER Grand Prix (Sunday, 12:30 p.m. ET, NBCSN), Honda leads Chevrolet, 737 to 698, in the Manufacturer’s Championship. Chevrolet has won all five in a row from 2012 through 2016 since the reintroduction of manufacturer competition.

NEOM McLaren Racing Formula E and Ian James set to race ahead of electric motorsports’ curve

As Formula E enters their ninth season and McLaren Racing is set to compete in last year’s championship winning car, Ian James is passionate about pushing electric motorsports forward at a critical stage as race technology begins surpassing that of the street cars.

Midseason, McLaren acquired the assets of the Mercedes-EQ team as they were already on their way to winning a second consecutive championship. With those assets in place and coming off a successful debut in the Extreme E series, James is set to usher in a new era in electric car racing.

Last week’s announcement that Jake Hughes will join Rene Rast behind the wheel of the NEOM McLaren Racing Formula E Team was the last piece of the puzzle.

McLaren’s electric portfolio is building with the Formula E team coming one year after they entered the Extreme E rally series in 2022 with Tanner Foust and Emma Gilmour. There were a lot of lessons to learn in that series with growing pains during the first three of five rounds. Rounds 4 and 5 were a completely different matter with the team crossing the finish line first in Chile before being assessed a time penalty.

In the final round in Uruguay, they scored an elusive podium.

“McLaren kicked off the season in Extreme E at the beginning of this year, so our first [electric] race took place Neom, actually out in Saudi,” NEOM McLaren Racing Formula E Team Principal James told NBC Sports. “At the time, we were in very early discussions about opportunities with the Formula E team. I actually went out there to meet with Zak [Brown, CEO McLaren Racing] and that was my first taste of Extreme E.

“Since the transition, I joined them in Chile in Atacama Desert, and then Uruguay last weekend. [The second-place finish was] a lovely way to round out the season. The fact that they got that podium. It was very well deserved. It’s a great team and a great series actually. It’s just so very different from anything else. The team’s done a great job in getting set up, and it’s nice now to, we’re trying to use that momentum that we’ve got from Uruguay to get us into next season when it kicks off next year, which will be great. I think we’re mid-March is looking like the first race, so a little bit of time to get things prepped for that.”

Synergies exist between the single seater and rally series. Lessons learned about battery power and sustainability in the electric SUV carry over so long as one is mindful of keeping focus on the individual needs and nuances of each series.

Especially now that electric racing technology has caught up, and is ready to surpass, the existing technology that has gone into building street cars.

When internal combustion engines gained the upper hand soon after automobiles were invented, racing paced alongside. The pressure of competition pushed the development of their commercial equivalents. The same has not necessarily been true of electric cars. Street cars were not designed to undergo the same stress as racecars – and that vulnerability showed up on the racetrack.

“Formula E has come along a long way,” James said. “I think one of the most notable developments is in the battery technology. In Gen 1, you had the drivers jumping from one car to another car midrace because the battery technology and capacity simply wasn’t where it needed to be to do the full distance. That obviously changed in Gen 2 and we saw a power increase as well to the 250 kilowatts.

“Now going to Gen 3, we have 350 kilowatts in a smaller battery. But that means that we’re relying on the regeneration of energy and for that reason, we’ve got also the opportunity to regenerate on the front axle as well as the rear axle now. So, there’s all sorts of things that are developing in the right direction.

“In terms of throttle response, actually, we’re now in a situation with electric racing and the motors that it’s instantaneous. And one of the advantages of electric over combustion engine is that the torque is instantaneous as well, so that gives you a lot more room to play with.”

No matter the power source, racing has always been about resource management. Drivers and teams select tire strategies they believe produce the fastest elapsed time and fuel conservation comes into play.

On one hand, electric racing is the same, but there is a critical difference. With the battery as both the power source and an integral part of the engine, there are multiple reasons to manage it.

In electric racing, the brain of the car is the software – and that is where James sees the greatest room for advancement.

“As we are working with our drivers and engineers – and start to look at functionality to improve our efficiency and our performance, that’s something we’ll continue to push because that development is open throughout the season,” James said. “That’s going to be our focus going forward and provides enough of a challenge for us to get our teeth into.

“What’s going to be fascinating is as Formula E continues, is to really look at which areas of development on the car are going to be the most relevant and ensuring that we can focus on those together with the manufacturers so we continue and use the series as a platform for technical development that can then feed back into the road car side of things as well.

“At the end of the day, that’s what motorsports always been, a very powerful tool for, and I see Formula E as no exception.”

Selecting Rast and Hughes as McLaren’s Formula E drivers was not simply because they know how to drive fast. James believes both drivers have the mental aptitude to execute energy management strategies throughout the race and squeeze maximum performance.

“As with many other motorsports, you’ve got a certain amount of energy that you’re able to deploy during the race and the management of that energy is absolutely crucial,” James said. “What we’re seeing typically in electric motorsports now is the hardware side of things. The efficiencies that we’re seeing in the powertrain as a whole, they’re getting up to the sort of 96%, 97%, 98% efficiency, so the gains that you get through that further and further become more marginal.”

With much more room for improvement, software is a different matter. To make the best decisions, the drivers need data, and that is where James believes McLaren Formula E will make their greatest impact.

“And then you really switch that focus to the software and that’s where you’re going to see the most the most improvement and the most gains,” James continued. “It’s then using that software to ensure that you’re deploying the energy in the most efficient manner during race, and thereby giving the driver the most performance. And that’s something which is incredibly complicated, but I find it a fascinating area to work in.

“The benefit of being involved in racing is you can really push the envelope in a way that you can’t do on road cars. And I think that that’s where that value comes in. It means that you accelerate the development a lot quicker. We will get ahead of the curve – and we are getting ahead of the curve now – and that will mean that the electric motorsports remain part of the overall development process.

“The key to that is also making sure that the racing’s exciting and fun for the fans. If we can, we can tick both of those boxes, then it’s got a very bright future ahead of it.”
