Hi Greg
I believe the various Prado figures (offical brochures) are linked in via the following site.
http://toyotacustomerstory.blogspot.com/
This is a
well documented story of someone who believes there car rolled over
far more easily than it should, at low speed, and that this was not the result
of any 4wd situation.
It further goes on to explain how brochure information, on which they purchased the car was misleading.
It then goes on the explain in detail the failure of protective saftey systems.
This is just representative of other info provided previously on this site and
not by me.
On some specific points you ask me E.G.
"How have you determined this risk (tilt angle 42°) as being an "issue"?
At what angle does this "inherent stability issue" disappear, 43°, 44°, 45°.?
Why does the "issue" disappear at the angle you have chosen? "
There is no specific point at which risk dissappears, it simply gets less & less
the higher the tilt angle is !
Sort of like fuel consumption, there is a range for a class of vehicle.
My car is at the top - so I call it bad !
For rollover angle the Prado is the worst in its class, hence we also call it bad !
(other classes of car are worse e.g. Troppie's)
I presume you accept the previously supplied report links like
http://www.monash.edu.au/muarc/
These demonstrate two key points (Tell me if you don't accept)
Point 1 - Large 4wds are a high rollover risk (3:1 over cars)
Point 2 - Rollover angle is the key measurement of this risk and known as
Static Stability Factor.
These things have consequences -
Running out of fuel is embrassing not life threatening.
A Rollover is quite different.
Hence the better the info we have the better we can take preventative action.
So I do my best to find out things like fuel use in remote areas etc , not so
we can brag about how good/bad it might be but simply so that I don't get caught out.
In the case of the Prado tilt table figures,
well shooting the messenger will make no difference to the rollover angle (although putting the body on the floor might help).
A better stratergy is to to consider the data carefully and work towards a solution.
ESC - now mandated in Victoria, and on the 150 Prado series, significantly reduces the problem for highway use (but not low speed 4wd).
(American recall versions excepted - due to late control system activation)
