Gday Henri, thanks for putting the pics up.
What are the two bars that protrude from what look like the spottie mounting points, into the radiator grille?
Are they secured to the actually body of the car, or just mounted to the spottie mounting brackets?

The colour coded bar looks pretty good, and molds well to the front of the car....definately offer more protection than a simple a frame.



The bars are the upper support of the nudge, they go through the grille and mount on existing holes (body of the car) under the bonnet. And yeah, they are what I used as the mounting points for the spotties.

The only thing that concerns me with retrofitting a bull/nudge bar from another vehicle is the impact to air-bag functionality as this bullbar wouldn't have been tested on an X-Trail and therefore would not be certified for it. Am not sure about the insurance companies in Finland, but in Australia, the insurance companies would eat you alive if they found out and more so if this proves to be the cause of the air-bags no deploying at the time of an accident.



Yeah, you couldn't do that with a T31 in Finland either, but the EC-certification requirement came into effect only after (in 2007 to be precise) my X-Trail was already rolling. The EC-certification primarily deals with pedestrian safety but I think it also certifies airbag compatibility. The real annoyance with this is that while undoubtedly the requirements for both EC and ADR are similar if not identical, it's not legal to install an Australian made bar on any post-2007 car in the EU.

In Finland the insurance companies are kept satisfied as long as the vehicle passes the annual (triennial or biennial for newer cars) engineer's inspection.

Personally, I wouldn't worry about airbag functionality, the bar is not nearly rigid enough to cause any problems with that. Any serious impact will cause the bar to deform so that the car's own bumpers and associated parts (airbag sensors) can do their jobs.

Why fit it then? Just for looks? What is the point of having so much tubes around the front of the car if they're not rigid enough to protect your car from any damage?

I didn't say any damage, it still prevents deer and other similar size wildlife from being hurled over the bonnet into the windscreen in a collision. But collisions with other vehicles are a totally different case in terms of energy transfer etc. I don't mind the bar preventing an airbag deployment in a head on collision if the speed is low enough not to cause deformation in the bar. Then again if there is enough energy and momentum in the collision to warrant an airbag deployment, that bar will not prevent that from happening.

But as for the question what it's for, it isn't primarily intended to provide protection in a car on car collision. Sure, it may save me a few scratches on the plastic bumper on supermarket car parks, but its primary functions are to protect from the terrain when driving off road, to protect the people inside from our native wildlife and to serve as a strong attachment point for the additional headlamps.

The Air Bag deployment isn't affected as much as you would think by the fitting of bull bars to modern cars. The computer controlling deployment does monitor deceleration which is affected by the bull bar (front end stiffer and so greater "jarring" to the G-Sensor). In any case the front needs to deform quite a lot before the air bags may deploy.

However there are other signals it considers, to judge which bag(s) to deploy beyond the simple G-Sensors eg the computer monitors the wheel revolutions at each wheel and in a collision they de-rotate very rapidly (much faster than a panic brake) and that is also a signal for deployment. If the front gets a sudden shock but the wheels are still rotating well then the air bags won't deploy as noticed in the recent video in this forum of an X-Trail collision.

If a passenger doesn't have the seat belt fastened then that air bag in front of the passenger will not deploy (so always fasten everyone's seat belts)

The soft front is there for pedestrian safety and that is why factory bull bars are so different now and actually collapse nearly as much as the original front panels in even minor collisions.

Re:


Henri,
I see your point on terain and deer protection but don't forget, an impact as little as 26km/h is enough to set off an airbag. If the bar is not suited to the make and model of the car that figure could increase.

Re:


If you want genuine protection for your T30/T31, certified ADR compliance, airbag compatibility and not just a fashion accessory then look at the following link.

http://www.tuffbullbars.com/uploads/media/X-TRAIL_T30T31_Range_01.pdf

I've got the black bar and can speak from experience that it's very effective against kangaroos (10 Roos in 45,000km) It also offers a protected mounting point for my HID's and comes standard with 2 aerial tabs. You can option more if you need them.
