I believe all the Euro cars except GFR have been used in a previous competition.

All Euro cars were 2011 cars, as it mostly is at MIS

For anyone interested the video from our e car demo is posted. This is the first driver on the endurance course after all combustion cars finished. We got ~3 laps with our second driver before our BMS threw a fault, limiting power. Not sure what caused that yet as we still had voltage in both battery banks.

Fast lap was ~51.633 with the fastest combustion car running 51.0??.

Haha. Did the organizers decide to dramatically simplify the layout of the autocross/endurance course this year, or is that how MIS always is?! That's like Formula Slalom. Reminds me of sweet 80's skateboarding competitions.

Having driven 3 different endurances myself in 2008, 2009 and 2010, I also think that this track was VERY wide, and fast. Maybe fast enough not to be easy, at least to do the consistent 52s, but still too forgiving. Endurances total times were VERY low.
2011 was something like that too.

I particulary don't mind the more open faster tracks. The only issue I see is that from what I see in videos, european FStudent competitions don't have tracks like these but instead they stick with the tighter type of track. There should be a more general trend I think.

Haha, I was totally impressed by electric cars too, when I first saw them running. Given the advantage on efficiency (fuel) we should have an interesting event at FSUK with merged categories. Other than that, here are some interesting statistics:

Does anybody knows why did Brookes DNF?Actually it would be intereting to get a list with all DNF's/ causes (it helps a bit trying to dial out unreliability and probable causes from your won car...)

I have a feeling that the faster track design this year was intentional after the disaster of the endurance event in 2011 where the track design was painfully slow and the event didn't end until 7PM.

I noticed street car tire marks on the course during the Thursday course walk--a dead giveaway that it would be fast. Did anyone see street cars driving the course?

What did everyone think of the E85? I watched Stuttgart have trouble starting in the noise warmup area. Kansas State and SDSM&T had trouble starting on it. Now that Sunoco has released a racing grade E85 (E85R), the time is right to push the organizers to make the switch. Then we will know exactly what fuel we'll be receiving at the competition.

Anyone complaining of tight tracks will get no sympathy from Australians!

When we went to FSUK in 2010 our tires got destroyed because we werent expecting the high speed corners we saw at Silverstone.

I've been only been spectating since the comp moved to MIS. But the track used to be MUCH faster in the days when it was at Ford Romeo Proving Ground in 2006 and 2007. I still remember the 4th gear sweeper...I think it was 2007 when wing car dominated the autoX on Friday, only for the organizer put in a much slower section for enduro, then the Western Australia car just dominated...To be fair, I do believe the rule have a different average speed requirement for autoX and enduro, with the former being faster.

The layout with the track on the back stretch of the NASCAR oval pretty much limited what the layout could be though. You are stuck with a pretty narrow and long area that you have to run back and forth on...

As as far as street car tire mark goes, every FSAE course to my knowledge were first driven by the track designed on some kind of road car to check....even the Formula Student courses(that are usually much tighter), I still remember Mr. Royce used to drive the UK course in his rental...

At FSG we setup the course by doing test drives with FSAE cars from former saisons. That usually works well to sort out any passages which are not fluent and makes sure, that the course is not too slow or fast.

As far as I know, the cars had to drive 20 laps, which leads to a lap length of 0.683miles. The average lap time of the faster cars was around 52s.
0.683miles/52s = 0.0131miles/s => 47.3mph which is far from being rules compliant (max average speed 35.4mph).

@Steven Webb: I totally understand that, the same happens for us testing in a karting track in Venezuela and then coming to MIS and having all these changes of direction and the faster (and cooler track). It is really confusing (we practice in Ven usually at 52C track temp. or around that). But at least during my years we learned how to extrapolate that to the conditions in MIS to make the tires work and to keep balance. It is a shame that we could only attend one competition a year because you learn so much (as a driver and from the vehicle dynamics point of view). We could never extrapolate so well for skidpad though.

The endurance course in 2009 was tight, but had some really fast sections and straights, I pulled 4th gear for quite a long time there. The 2010 track, although being a little too short, was INSANE, I loved it.

I was on track and it was def a high pressure fuel leak. Unbelievably huge ball of fire. Luckily everyone was ok.

Since Carnegie was the first racecar on the new paved surface, I guess Penn State gets the distinction of first fire....

Also. The electric cars from TU Munich and Kansas were unbelievable. We should create an electric section on this forum and get this competition off the ground for next year.

I got a terrible video of it.

There were also two or three cars that crashed into barriers. Although I agree, that drivers should be aware of the barrier position and probably not push, if these are too close, I still question their position. Especially at the start-finish-line. There was plenty of space to put them 6 feet or more away of the track instead of putting them, Monaco like, directly at the track.

Having been graduated from FSAE for a while now, I step back now and think how amazing this is:

You have three wildly different cars running of three different compound/manufacture tires (hoosier 10", hoosier 13", goodyear 13") with three amateur drivers that haven't seen each other in competition for a year, getting two runs per driver, and they still manage to be within 0.2s of each other.

Results are up. They're posted under the California results for some reason.
