GTR Madness

****ing hell!! :eek:

Why could the clever people at Nissan not have the pedestrian safety system thing seperate from the ECU so that doesn't need to be replaced aswell?

£11k for a tiny bump like that is shocking!
 
Surely that's a wind up? What on earth is a pedestrian safety device and why are in the middle of our roads for us to warrant fitting one?

Unlucky if true, and one way to earn some £££.

It is a separate ECU from the 'main' one.

The idea of the safety system as far as I can see is that basically it stops the pedestrian being smacked into the windscreen...although it may fire them over the car and onto the wing...:p
 
I think I would be pulling the cables on that system, then removing the "pedestrian safety system fault " Bulb!

Sorry, I would take the risk with the pedestrians head :D
 
Expensive for sure but not exactly strange that you need to replace the ECU, i'm shocked the wiring doesn't need to be changed.

If your airbags get set off you should really change the ECU / Some airbag wiring and the crash sensors.

The system in the GTR seems a bit thick tbh.
 
Surely if you were to have an accident (head on), the bonnet is primed to go backwards at that angle....chopping up the windscreen/head area? or would the side struts protect the occupants?
 
If it's a full frontal impact it's probably set to stay down. Slight bump in a small section of the front end and it then goes off as it thinks it's a pedestrian, else it should realise it's larger and not deploy.

My thinking anyway, don't know how it actually works. :)

It bumps the bonnet up on detecting a collision so the pedestrian thwacks the lifted bonnet, which cushions their impact.

Indeed, I expect there are limits regards how much distance there has to be between the underside of the bonnet and the engine block so that a pedestrians head is only smacking into 'thin' metal rather than an engine block.

It wouldn't surprise me if the GT-R doesn't meet such criteria in normal form so has this bonnet popping thing to give enough clearance.

I very much doubt it's intended to shoot people over the roof anyway :p
 
Solution, put spikes on the bonnet facing upwards!

It'l learn that damn ped for causing such a silly repair bill.

:p

Indeed, several problems when a person hits the front of a car, main one is the bonnet deflection, don't know if you've ever seen any crashes or tests involving pedestrian impacts but the deflection is usually enough that the person if effectively hitting the engine.

One point I’m not keen about but I’m sure Nissan have addressed, is if you look at modern bonnet hinges (around 1998 onwards) they have a new latch that stops the bonnet going backwards into the passenger cabin, now looking at the Nissan system when the bonnet pops up I can't see any such latches, so as already stated it must be a speed dependant system.

If the GTR is going to react like this during every low speed front end crash I’d expect the crash detection to be better than it seems to be.
