A brief look at the UNSW EVE solar electric car at Electronex 2016, the world's fastest solar electric car.

Loved it. Thanks Dave.
Would like more info on drive electronics strategy and stuff. I'm off to Google to find more info about them.

So they have an ultra low inductance motor architecture, and then have to add extra external inductance into the phases to prevent excessive current ripple |O (where's the massive face palm smiley?? )

<nit_picking>I think stating 'worlds fastest' is a bit of a misnomer. Fastest; meaning highest maximum speed fastest time on so many laps of a race course, best time on a multi-day 1,000kM trek? These competitions typically also include penalty point, etc. so having the most point/winning is not even about a fastest completion time. OK, so maybe I'm being nit_picky because I think our solar car team is the greatest. :)</nit_picking>
All <nit_picking> aside I love student competitions or anything that gets students with tools in their hands building stuff. This types of events are multi-faceted in that they involve not only the technology in the car but also the logistics of getting a load of students and gear where they need to be, and the strategy devised based on the strengths of the car, weather, course, etc.
What I most often see overlooked by students (and faculty) alike is the reliability of what they build. It does no good to build the latest gee-whiz motor/controller/etc. only to have it break down several times in the race. Even more mundane things like gusseting tube chassis joins can be over looked resulting in a break. It can be a great learning experience.
Last semester I was making some parts for a student who was working on a sort of mobile information display device (picture a LCD TV with a Raspberry Pi on the back attached to a two wheel dolly). He was working on designing the 'two wheel dolly' apparatus as the IT department was not happy with commercial offerings. I had made some parts for him the previous semester and when he came in to the shop he said something like, "My design worked but it broke! But I took MickeyMat (Mechanics of Materials) last semester and I now understand why it broke and that it broke right where it should have." The wonders of practical hands on learning...

Agree with Jeff. (as a member of Aurora for 15 yrs). We also hold many records, but as Jeff says, race rules always have a penalty system to "level" a class.
Our last WSC race, we were held back a day as a handicap. It means nothing. We do it for the advancement of Solar electric ! which will HAVE to be the future.
