They did make a record run and return later that day and then that was it. It sounds like they never figured out their issues at full power it kept shutting down.
From their blog:
Given the limited time available the Bullet set out to attempt the hydrogen fuel cell LSR. The attempt began around 1pm local time. In order to qualify for a record, the vehicle would have to complete two runs in opposite directions within 60 minutes. The BB2 started at the far end of the track, with a plan to refuel at the south end, where the pit area is located, and the restart in the outbound direction within one hour. The timed mile for the "flying mile" record is in the middle of the 11-mile course.
One more time, the BB2 had a strong start on both legs of the record runs, but had an automatic shut down once it reached full power, in spite of all the work done during the preceding 24 hours to rectify the hydrogen flow problems. Thus, on both runs the Bullet coasted through the flying mile without any power. Fortunately, coasting is a relative concept, and BB2 was able to average approximately 130 mph along the timed mile, resetting the fuel cell vehicle record in class 3 (unlimited weight) by nearly 50 mph. I will send images of the certificate and other details of the run as soon as I have them in digital form.
I want to make it clear that we shall investigate the history of FIA records, as I believe this to be the first time ever that a vehicle has actually set a FIA record with ZERO TRACTIVE POWER.
In summary, during the past two weeks the Bullet2 has recorded the fastest ever speed for a hydrogen fueled and fuel cell powered vehicle at around 224 mph, and has set the official FIA world record for Group XIV-class 3 (fuel cell engine, unlimited weight) at around 130 mph.
We are proud of the accomplishments of the OSU student team, and we look forward to reaching even higher goals next August. The team will be returning to Columbus late today.
