From articles I posted recently:

LandCruiser 200 has an all-new frame and newly designed underbody reinforcement in the upper body.

They are designed to act as one unit to better absorb impact in a frontal collision, by bending the frame and axial compression of the underbody reinforcement.

The frame has been completely redesigned at the front, as a moment-reducing structure.

The front side rails have 30 per cent more horizontal offset and 40 per cent less vertical offset to increase impact absorption.

The frame's side rails have preset bending points between the number two and number three cross-members.

Impact energy support areas (large reinforced box sections) have been built into the side rails at the number three cross-member joint.

These box sections are pressed from high-tensile sheet steel and have reinforcements in all four corners and for the entire outboard plate.

The front frame structure has been designed to increase impact absorption while increasing ground clearance for the front differential and the power steering box.

Inside, the LandCruiser 200 has head impact-absorbing structures for the inner materials of the pillar garnishes and roof headlining.

Each pillar garnish has one-piece moulded ribs to act as energy-absorbing panels.

The roof headlining has energy-absorbing resin angle brackets.

Are these improvements that the 200 (2008 and newer) have over the previous model or have these been implemented somewhere during the run of the 200 (2008-current)?
 
Daily back pain will certainly make you look at life decisions in a different light. Sorry you are dealing with that.



I’m not doubting the 45* thing but am curious where you saw it. I remember a picture of an 80 on an apparently toyota factory rig that tilted it sideways really far and could catch it if it started to go over. I assumed they did something similar for the 200 but hadn’t seen the numbers quoted anywhere.

Yup so, officially, it is 44 degrees side slope.

The above is in comparison to LC 100.

All this discussion makes me wonder what happened here. I ran across these pics on car-part.com looking for a rear view mirror. Apparently in California, to me it kinda looks like it went over a guardrail and maybe off a cliff? Seems like even that might not be enough energy to cause this level of damage though, unless it was quite a cliff.

Front passenger compartment looked great. No blood or anything, which is a good sign for those occupants. The second row looked good too, other than driver side having a lot less headroom.

Over/Under on the chances the other car was a Smart For2 car?

Thanks for posting this.
Title page says this is for 200’s big from AUG 2015 onwards but in the content it says this 200 was produced in 2012.
Wonder if there were any changes in the performance of later years.

Tested in 2012 per sticker on door.

 
It's in my owner's manual. 0.8 inches front and 0.6 inches rear.

Link? What year range does this apply to?
 
Thanks. I got that.
Was curious if there are any differences in the crash performance of a later model i.e. model year 2013 and later.
Guessing not since they made these applicable to MY 2015 - onwards

I found that discrepancy odd as well. Why say that it is applicable to 2015 onward, when you tested a 2012?
 
There are a couple of things that I see that are being suggested as "improvements" that are actually possible bad news. Adding "steel bumpers" may actually keep your airbags from working as intended and will alter the crush zones built in by the manufacturer.

Some aftermarket manufacturers tout "air bag compatibility" and imply that they have been crash tested. But, read carefully, it becomes obvious that they've merely studied the existing crash tests and think that they won't interfere with air bag operation.

From one of the websites (bolding is mine)

"ARB has invested heavily in vehicle crash barrier tests to validate the performance and compliance of its air bag compatible bumpers. To ensure compatibility, ARB assesses each vehicle’s frontal crush characteristics and replicates the crush rate in the design of each air bag compatible bumper and mounting system. Using this method ensures that the vehicle’s crush rate and air bag triggering are not altered when a bumper is installed. "

Also, if the crush rate is not altered, then what does this bumper actually do? (yeah, I know that I sound like the kid in the dishwashing detergent ad)

The car, as designed, is as safe as it gets. To protect occupants (like others have said) make sure that everyone is properly belted, the seats are mostly upright, car seats are installed properly (almost none are) and anything loose is tied down. Remember that anything can become a projectile.

I've seen flying boxes, cats and dogs kill people in accidents. I've seen a can of beans kill.
 
Side airbags generally will not deploy due to a front impact crash.
Not necessarily correct. The airbag system makes thousands of calculations to answer one question and only one question - "If I deploy, will I reduce injury?" The system figures out where the seat is, the angle and severity of impact and decides where the occupant is going. Then the system decides what to deploy (and how fast) to keep the occupant from hitting sharp bits.

No airbags are deactivated for the tests and the testers know where Vince and Larry are supposed to go based on the impact.

Yeah, that's why I said generally.

I wonder how many folks have been killed or seriously injured because a coffee tumbler, bottle or can they were drinking from (or holding in front of the steering wheel) smashed into their face by an expanding airbag. Seriously wonder, because it would be pretty violent...

I agree that steel bumpers likely won't make the truck safer, and there is a chance they will make it less safe. But it is worth noting that ARB does actually undergo crash testing of their bumpers (which is what is meant by the first sentence in your quote from their website).

I am putting an ARB bumper on my LX, but I have no illusions that I am becoming safer. My hope is that I am about as safe as I was before, but if putting a steel bumper on the front would make the truck safer, Toyota/Lexus would have done it. But I do think there's value in going with a company like ARB that has actually done crash testing and made a conscious effort to replicate things like crush rates.
 
“Safer” in this context goes beyond the occupants of the landcruiser. Front bumpers are designed to protect us, but also anything we run into, be it the drivers door of a Honda Civic or some poor guy crossing a road. A steel bumper in those situations is generally MUCH worse for the other end of the accident.

I totally get the thinking that whoever is in our vehicle is the priority, but as I get older I think more and more about how my decisions impact others. No pun intended. That is one factor in my decision to keep stock bumpers on my 200. Cruising fuel efficiency and lack of need are major others.
