So I signed up for fsae at my uni and got offered an interview but I’m worried now and just wondering generally how the meeting goes. I signed up with a portfolio and resume and a couple essays but yah. How technical will it be what kinda questions should they be asking? I know it differs between unis but yah

Just saw Get Racing from Dortmund achieving P4 in AutoX with a 200kg+ steel tube-frame is pretty damn impressive. They are also P6 overall at FSG 2026, with P7 in Endurance as well. Especially considering this was, I believe, their first year running AWD, and they’re doing it with a 200kg+ steel tube-frame car while a lot of the quick cars are significantly lighter. Obviously weight is still a massive disadvantage and I’m not saying the concept is better, but getting that kind of AutoX pace out of a car like that is genuinely impressive. Getting that heavy of a car to P4 in AutoX is no small feat and had me starting to wonder where that pace is actually coming from…… is AWD that strong? And if yes, what makes it that strong?

We are looking into outboarding our diff for our EV. But we haven't seen any teams that have diff brake on outboarded diff. Is it generally considered bad practice, or is it doable?

Our team participate in the static event of formula student turkiye. our car progress around 10 %. at 30 August there is vehicle status deadline. do we need to upload our vehicle even we only participate in the static event. and can we just upload the unfinished chassis for the vehicle status video?

My team has held on to our last four sets if harnesses for some reason. Id hate to just throw them in the trash. What at other teams doing to upcycle/reuse them

We are an LV Hybrid team with an inboard motor. We use a KTM 390 engine, we are thinking of implementing pneumatic shifting for next season. The problem we are facing is we are not able to achieve a half shift with pneumatics for the neutral gear, which lies in between the 1st and 2nd gears. Other teams which use pneumatics, how do you guys achieve that with pneumatics ?

Or we are open to other suggestions for gear shifting mechanisms as well.

We’re facing an issue with our Emrax 228 + Bamocar D400-400 setup.
With the car lifted on jacks, we completed precharge, gave RFE/run, and APPS input. The motor ran normally in the correct direction.
After putting the car on the ground, precharge initially failed 2–3 times, although the TSAL was green. We fixed the precharge issue.
Now, after successful precharge + RFE/run, giving APPS input makes the motor run in the opposite direction, causing the car to move backwards.
Setup:
Emrax 228
Bamocar D400-400
Orion BMS 2
Dual-channel APPS
Any idea what could cause the motor direction to suddenly reverse? Could this be related to the controller parameters, resolver feedback, or CAN commands?
TL;DR: Motor worked correctly on jacks, but after putting the car on the ground, it now runs in the opposite direction despite the same RFE + APPS procedure.

Do anyone have any idea or expertise in modelling leaf spring via Adams Car? Need help

Is it possible to finish manufacturing a new FS EV within a 45 day timeline given:

A team of 20(10 are experienced) .

All CAD designs are complete.

Previous 1 car with TI not cleared but all safety systems installed, Car runs, not tested to peak.

Hi, we are a Formula Student EV team. Could you suggest some ideas for harnessing and connectors for our car , and also what type of connectors and wires are you using for your car ?

How is Dresden doing in scrutineering?
How was the new judging system, seems to give less time for individual topics?
Are any 2027 rules beeing teased?

Tell us the lore!

Does implementation of MBSE in FSAE teams truly help in overall management of iterations , failure analyses, risk management etc. Or is it an unnecessary added complexity ?

Our car isn't able to lock the wheels under hard braking. We're using a Bosch 19.05 mm master cylinder with KBX Vespa single-piston calipers (29 mm piston).

The calipers are moving and we have braking force, but it feels much weaker than expected.

Could the 19.05 mm MC be too large for the 29 mm caliper, or is there something else I should check?

Any advice would be appreciated.

Just for a reference, can you all tell you appx lv battery capacity?

Hi everyone,

I’m a mechanical engineering student currently designing and building my own car around a 1998 Honda CB600F Hornet engine. I’m looking for an accurate 3D scan or CAD model of the engine’s external geometry to help with chassis design, packaging and clearance checks.

I only need the external shape, so an STL, OBJ or similar mesh file would be completely fine. STEP or another CAD format would also work, it doesn’t need internal components or fine details.

I’ve found a scan of a 2013 CBR600RR engine, but its external dimensions, cases and mounting points are too different for reliable clearance work. A scan of the correct CB600F Hornet engine or a CBR600F engine from the same generation would be extremely helpful.

Sorry if this isn’t the right place to ask. If anyone knows another subreddit, forum, FSAE team or community where I might have better luck finding a scan, I’d really appreciate being pointed in the right direction.

Does anyone have a model they’d be willing to share, or know of a team that may have previously scanned one?

Thankyou fort any help.
