The vehicle kept accelerating through the run (as demonstrated by the fact that the exit speed is higher than the average speed along mile 5).

Some technical details:

Run time: 90 s

Peak power drawn: 550 kW (740 hp)

The stack temperature reached 70 degC, with plenty of cooling capacity left.

Transmission cycled through 4 of 6 gears.

The run consumed 0.8 kg of H2 and 15 kg of heliox (that is pretty much the whole tank – we’ll need to adjust the stoichiometry on the leaner side, but there is room to do that)
