I have a new Toyota Troopy 2008 model - V8 Diesel
Can anyone provide me with information or links to sites that have tested troopys on tilt tables. I'd prefer actual test results put out by testing or motoring associations. Test on the new V8 Troopy (increased width on front wheels) would be good but tests on previous models would be adequate.

Toyota would be the best people to ask, they would have it.

Mining company's ask the same question.

Why do you want to know?

Thanks for the replies - keep them coming.
I did find some information from a Monash University 2000 study for the Victorian Police. They quoted the Troopy’s tilt angle as 38.9 Degrees.

I don’t know whether this figure includes 180 litres of fuel in the long range tanks or not. The Monash study noted that adding 100kg of ballast to a Ford Falcon increased its stability significantly but they included no further details.

Recently I travelled the Old Telegraph Track to the tip of Cape York and some of the ruts set the Troopy on angles that made me uncomfortable. I hate guess work and now I have a figure to work with - allowing ample safety margins of course.

We had the same issue on the OTL last year- and the 'lean' was always on HER side..sure did get some comments like "i don't want to have eye-to-eye contact with ants !!!"
Our Troopy had been on extreme angles- even with a loaded roofrack- with no issues..

I can't answer your question but I would point out that sideways stability does not just depend on the static roll-over angle. If you are moving forward your vehicle is likely to roll at a lesser angle then the static angle. Also, any sideways slipping combined with the slightest bump will throw the vehicle over before you reach the static tipping point. You may get a 'rough' idea of the angle by estimating the centre line of the engine at the front of the vehicle and then lining that point up with the outer edge of a front wheel where it meets the ground.

Kiwi I agree with you 100%, the slightest rut or steering direction change will send you over.

I work on the sphincter theory, when that starts contracting you know you might have gone to far.
I was slashing at home a few years back. I used to slash across the hill as going up and down the wheels used to lose traction and slide. I had done the same thing 100 times, then hell the bloody tractor tried to attack me, it lifted and with luck it lent against a tree. It scared me big time and all that had happened was a wheel had dropped into a hole. Also the theory that you jump up hill was blown out of the water as I just fell down hill right into the path of the tractor.

Gave the tree a big kiss I did and then polished of a bottle of Bundy.

The Monash study I reffered to in another post is one of the better documents and our cars tend to range from 38 - up to the highest ranking, the GU at 48 degrees.

RACV have done many tests , but I don't recall the troopy amongst them.

These days the NHSTA in USA requires all cars to have a SSF figure and publish the figures.

If Troppies are sold in America then a figure will be available on their site.
