UMSolar - Aurum - WSC Day 5 (Finish)

Submitted by Bronco648 on

FINAL RACE DAY: A bittersweet ending

Michigan hung onto third place until the last 30 miles of their 1,800-mile journey.
Clouds had covered our campsite on the morning of the final race day, so the team wasn’t able to get as much of a charge as they would have liked. Nevertheless, the mood was cheerful. Silly, even.
“One sad sunbeam,” one team member said, pointing towards the mountains in the distance at a small opening in the clouds.
“It’s charging a cow,” another added.
But then, shortly after launch, some chatter about a motor came over the radio. It wasn’t clear there was a problem until we in the media van heard Aurum’s set speed was around 52 mph. The previous afternoon, we’d been doing 65 or higher.
Tokai’s Challenger was going 66. Uh-oh. It was quiet in our van...

Final Timing Board HERE.

I have to say that I'm pretty disappointed that Aurum couldn't maintain a 12 mile lead on the last race day. Why couldn't the car go faster than 52mph? That question remains unanswered. Perhaps they didn't get enough of a charge and were concerned with draining the batteries, on course. What was the motor's issue? I don't know. Fourth overall versus the world is still impressive but this leaves a sour taste. For what it's worth, Stanford's team finished sixth, another good showing for the US.

It seems like U of M has been close to the top (top 3-5) in the world for the last 15 years, but not quite there.  What are the difference makers that are keeping the team from getting over the hump?

The biggest thing "holding the team back" is also what makes the team great: it is run entirely by students and 90% of them are undergrads. This means there is a high turnover rate and they don't have as much time to dedicate to the project as the other teams.
For example: Nuon is entirely run by grad students who take a year off from school to dedicate 100% of their time to the solar car project. Tokai's car is designed by professors, not undergrad students like Michigan.
Money and access to cutting edge technology contribute too, of course.
We can win international races, as demonstrated by our victory in Abu Dhabi, but that team only had 3 undergrads and essentially a blank check budget. The rest of the team was a bit of an "all-stars" roster of some of the most successful alumni from past teams. That race was much shorter too. Plus Nuon didn't show up.

Additionally, I'm pretty sure that Panasonic bank rolls Tokai University's team. IIRC, in the last WSC (2013), Tokai had solar cells that weren't easily available to other teams, giving them a distinct advantage. This year, equipemt was pretty equal across the board. Strategy played a big part.

This is the week for inexplicably coughing up a loss, I suppose, but in the long view this is a great outcome and continues the UofM tradition of strong showings.

How did the MSU solar rolling beer pong table do in the overall standings?

I had no idea these things go so fast now. It seems like not too long ago, they were barely making 40mph. Do you have a source for winning average speeds for each year?

EDIT: It actually looks like they've tried to limit speed through rule changes to avoid running afoul of Australian speed limits.

Your edit is correct. Rules were relatively unchanged from '87 to 2005, so that's a clear progression.

2007 introduced mandatory upright seating and smaller array area, 2011 mandated silicon cells (rather than the more efficient but very expensive space grade gallium arsenide), and 2013 required 4 wheels.

The Wikipedia page for the World Solar Challeng has a pretty good list of results with average speeds.

I saw tweets this year that indicated 110 kph was do-able. That's about 68 mph. I'm pretty sure Aurum can attain closer to 90 mph, if not more. Of course more speed = more energy consumption. I'll try to see if I can find the qualification results from Hidden Valley raceway. That will give you an idea of top speed, albeit on a road course not a drag strip.

I've followed Michigan Solar and the WSC for years.  I'm as dissapointed by us coughing up the lead to big bad Toaki as I am the football team coughing up the lead to MSU.

"That question remains unanswered" because the team hasn't posted anything yet, probably because they are physically and emotionally exhausted and busy enjoying the first hot showers and soft beds in a week.

These aren't professionals. They aren't even heavily recruited athletes on scholarship.They are regular full-time pay-their-own-way students subsisting (and it usually is "subsisting") in Australia on funds they raised themselves from a network of hard-won corporate sponsors. "Sour taste"? "Coughing up a loss"? Let's try to go easy on 'em okay?

The good news is that this is the closest to first place (less than an hour off) Michigan has ever been. They'll learn from it and come back stronger than ever in 2017. And anyway, this really is one of those events where the journey is more important than the destination - every one of these racers has just had a life-altering experience, and you'll see great things from all of them in engineering and business in the future.

"The good news is that this is the closest to first place (less than an hour off) Michigan has ever been." I think that's an important statistic. You can't really play defense in solar car racing, so you just have to go as fast as you can and hope that the other teams can't go faster. In that sense, this is Michigan's best WSC result.

It is tough. Your post just came off as more critical of the students than seemed necessary. Particularly the "why couldn't they go faster? That question remains unanswered" part rubbed me the wrong way a bit, sort of implying they blew it and owe you an explanation. Probably just Internet not conveying tone correctly.

I really wish that I could connect with former members of the team, such as yourself, that have accounts here. You're capable of providing so much insight that I obviously lack. Granted, you may not be intimate with Aurum but you certainly understand how the team is assembled and what the various respnsibilities are. I'm pretty sure no one else, on the Board, knows about Scout, Weather and Media. It would be cool to better understand the team's hierarchy. Sadly, it's not easy to do this from afar (Chicago) otherwise I'd ask if I could visit the facility and chat with the students that comprise the team. I have nothing other to offer except enthusiasm (unknown to Mankind) and a few pearls of wisdom from an old time racer.

No, they don't owe me anything and I apologize of I came off critical of the members of the team. That wasn't my intent. I guess the lack of info, at this point, just leaves me wondering. And, you posted a valid point; they're most likely beat and trying to get some much needed rest. I have no issue with that. I really would like to know what happened, more so for my own curiousity than anything. However, I doubt I'll ever find out. Maybe that what had me in a sour mood. Apologies. As a former racer, it's tough to stand on the sidelines, half a world away, and wonder what's going on.

I would not apologize too hard.  If I was on the team, I would be happy that there are people who care enough to feel the emotions of a tough finish like that.  

It's a hollow feeling to do all that work and nobody cares, or they are oblivious to what you actually do . . . "Oh look, the Michigan Solar car finished fourth in the world.  That's nice.  Do they get to race in the Daytona 500 now?"

I have been following UM Solar, the ASC, and the WSC for years.  I know how hard they have worked to break through that Nuon / Tokai barrier, only to come up short each time due to simple unlucky events that could have easily gone the other way.  More than anything, I feel disappointed for the team.

But proud of them at the same time.

So it hurts to see Nuon and Tokai still ahead, but if you turn around and look at who's behind you - M.I.T., Stanford, Cambridge, etc. - it's a hell of a great vantage point.

Disappointing for sure, especially since we beat Tokai and Twente in Abu Dhabi 9 months ago (albeit with a different car and a team of mostly alumni). Keep in mind that Twente's biggest sponsor was threatening to pull funding if they didn't win so they had a huge incentive to pullout all the stops. Michigan's strength is strategy so my guess is it came down to simple technology differences.
This doesn't feel like the MSU loss because it seems like we got beaten fair and square. If it came down to simple traffic and lane selection outside Adelaide (which can actually make a difference) then it would be different.
As a former driver for the team I can imagine the uneasy emotion of running a great race yet still not doing what you hoped you could. They should still be very proud of themselves as this was a historically close race and they represented America well.

Sorry, still not over the football game.  Seeing this article puts me over the edge.  What ever this is . . . curse, hex, evil joke. . . . I want it all to go away.  Why can't my Michigan teams win an important game, an important race.

You are right, according to the WSC's results table. I wouldn't be surprised if those teams have some sort of relationship with Tokai University. MIT hasn't been particularly strong in the last decade. Stanford, University of Minnesota and Missouri S&T are usually Solar's main competition. I'm guessing MIT doesn't focus as much on their solar program as others do. actually, I'm a little surprised Purdue and Illinois, two strong engineering schools in the B1G, don't have teams. Formula SAE also attracts a lot of engineering students.
