The over-sized red firesuit really goes well with the green chassis

Not really. But at least I only got cooked to a nice medium rare in the sun by using it instead of the black suit.

Formula Hybrid this year was a bit of a disappointment, mostly due to a shoddy crimp that I made stopping the car during both autocross and endurance. Oh well, on to FSAE electric next year.

It was a stupid thing that I should have fixed when it felt slightly loose when I put it together. But it didn’t come apart when I pulled on it so we ran with it.

Actually red and green are complimentary colors.

Should’ve used duct tape.

You have no idea how much tape is on this car. We estimate there is at least 20-30 lbs of various forms of tape on this car. The horrible battery pack design this car was built around is so bad that it requires half a roll of gorilla tape to seal it back up after you work in it. Never let a team of mechanicals design a battery pack on their own without an electrical assisting. This pack is terrifying to work on.

I really miss working on a team for FSAE. I graduated before FSAE electric really became a thing. I can always look back with fondness that my team made sure new rules were added every year we participated. Pushing the envelope on a shoe string budget really made us get creative.

Why not just use an off the shelf battery?

While you can technically use an off the shelf battery pack it can be very hard to prove that it actually complies with all the rules. In general it is far more effective to construct your own pack from off the shelf cells specifically for your car and demands.

We’ve always been a shoestring budget team as well. The car above was about $35k over 2 years. We learned the hard way in the past to keep the cars simple if you want them to work. It’s looking like we are going to have a bigger budget for next year but we are still keeping it simple and buying nice batteries, a nice motor, and a nice controller for use in a simple, lightweight, RWD car. We want to avoid what happened last time we got a big budget when we ended up with a car that was capable of 300+hp on paper but ended up being an over-complicated 1400lb pig that never worked.

1400lbs!?!?! Is that a typo? I never participated in hybrid but the heaviest I have seen was around 600 lbs with no driver. My team always strived for 350lbs so we could say to anyone who asked that it weighed “tree fiddy” If possible you guys might want to look into carbon fiber, some companies will donate rolls for sponsorship. The rolls would have a few imperfections which means they can’t sell it but it’s worth it’s weight in gold to us. If I remember right we had a good thing going with Hexcel

No typo, it was a pig. We have a photo from when the frame first came in with 12 people sitting inside the frame. For Formula Hybrid most cars are around 600lbs. The car in the photo weighed in at 832lbs this year and we expect to be able to easily drop 200+ lbs for next years car. We have already saved 160 lbs with our new battery design (current pack is 280lbs, new pack is 2 60lb modules) and should be able to save even more with a smaller frame.
