Depends how big the fire is, if my kinder egg spontaneously combusted i might call these guys out, if my minibus caught fire i wouldn't rate my odds so much.
The idea is to get to the incident as quick as possible to stop or slow the progress of fire. If there's a pile up then you want something like this to stop the fire progressing until the big trucks arrive. Big trucks + kesslechen (ics) results in a slow response time.
I'd have thought the car would have been detuned to save the running costs. Even in a detuned state it would do the job!


As for being detuned, nope, saving running costs and the Nurburgring? Yea right.
If anything it should be tuned. Think of a GTR but then think of it carrying a huge tank of water.
But it isn't water, it's foam isn't it?
Which doesn't weigh anywhere near as much as water.


Would it not be better to put 4 or more locations scattered around the circuit and have some sort of rescue vehicle dotted at these locations to save those valuable minutes?
I think if I was going to the ring I would take my own extinguisher too, you never know!
