Sad to see that one team took their battery pack back to the hotel, just to have a thermal runaway. Hope the injured students gets well soon!

Congratulations to all who competed. Seems like it was another well run event.
Anyone got any good gossip, or inside information as to the challenges some of the teams faced?
From scoreboards it looks like GFR couldn't get their combustion car started back up after driver change, costing them dearly. Anyone know what happened?

I was watching the live stream and you could hear GFR cranking the engine at a lamentable speed. Could be insufficient battery charge, or perhaps there were a few failed attempts at a proper speed first (a hot single is always tricky), and the battery ran out because of that. Whatever the cause was, it was heart breaking. I remember very well how it feels to lose a near-certain overall victory during the driver change, so I hope the guys are already focused on the next competition and wish them the best of luck.
Big congratulations to Karlsruhe for winning FSE. They have been among the best teams for so many years, and it's great to finally see them taking the big one home. I'm sure the whole FS community is happy to see them win.

It was of course heart breaking, but for what it's worth: I don't think GFR was on track to defending their title. Up until driver change, they were about 3 seconds off pace in the endurance compared to TU Munich. They were on track to a 3rd or 2nd position overall.
Their efficiency score and second driver speed are of course unknown. However, based on lap times in Austria the second driver is a bit faster, but not enough to make up for a 3s gap on average.
Looking back, Munich was pretty dominant this weekend and would have had an even clearer win even with GFR finishing endurance, had it not been for a botched acceleration where they only got 3.5 points.

One of the things I noticed was Monash's performance. Even though they scored points in every event, they finished 21st overall. That would have been a bit higher without the penalty and without some problems at autocross.
When they were last in Germany, in 2014, they were on track to finishing 2nd overall had they not DNF'd in the final lap of endurance, if I'm correct. And even with 0 points for endurance, that year's team finished higher, and with more points than this year..
Does this say anything about the current level of the Australian competition? They are the 7-time defending champion after all. Or did Monash just have a bad weekend?

Yes Thijs, I have to agree.
Was really sad to see Monash struggeling throughout the whole European trip this year. From Silverstone via Spielberg to Hockenheim, they never showed anything close to what was expected.
Not even in their strong suit, the Skidpad they were able to post times that they did in earlier years.
I know that they had a lot of issues (as it was quite obvious during AutoX on Saturday) but still a bit disappointing.
Also sad to see that the new Continental tires caused problems for two strong teams during Endurance. Hope the guys can fix it until Spain.
But awesome performance by Karlsruhe and Munich. It is really great to see some "new" faces (besides the "typical" GFR, Delft, Stuttgart and Zurich winnners) up there. Congratulations to both teams. Espeically to Karlsruhe; dominant throughout the week, awesome stuff and highly deserved!
(Also huge tip of the hat for my former team. Killing your AutoX victory and taking a 15pt "penalty" in such a tight competition by acknowledging a cone is a great thing. I'm very sure that "back in my days" a lot of teams would have done that differently. Great job guys, am really proud!)

Can you be more specific about these tire problems? Just curious (and possibly looking ahead to a future TTC tire test).
Alternatively, like any engineer should do after identifying a potentially dangerous situation, is analysis their design, proof test and rate their rim, UWAM tested to failure a few of the earlier rims (before my time), as such, we had a number not to go past.
There are so many things that can be dangerous if the risks of failure are not controlled. Why is there not a focus on inadequately designed wishbones? (I'm not saying the most recent failure was poor design, I wasn't there, so no offense is intended)
The last thing we need is additional knee-jerk rules

Thanks to all for your replies. We call this failure a de-bead or debead. Sorry to hear that this ended endurance for two teams.
During TTC testing at Calspan TIRF this has happened a few times--at low pressure, cornering under high load (it also happens occasionally with larger tires). Often, there is enough airflow through the regulator and rotary union to re-inflate the tire and continue the lab test, so only one slip angle sweep is compromised. If a tire/rim is marginal, I've seen the bead start to crawl away from the flange and then pop back on when the steer angle reverses. A related problem is rotational slippage between the tire and rim during drive-brake testing. Various bead locking mechanisms are discussed in the TTC forum. From memory, we have had the TIRF staff mount tires dry, minimizing lubrication seems to help. They are very careful about overpressure during bead seating!
