4X4 Driving and inclines.

Agree with everyone else, 18 seems low and could be beaten.

Can we see his maths for 18*?

Show him this, Bob

& this

If that doesn't work, this should convince him.[ However, there is always the possibility he is just trying to stop you attempting something that may be a bit dangerous, especially with his daughter in the vehicle, always drive safe ;)] Bob

Real Man's 4WD Track - YouTube

a 100% slope (1:1 or 45 degrees is) easy to climb in pretty much anything if you have enough traction and power.

if memory serves clean dry sand naturally forms up at a 30 degree angle which is a 66% slope or 1:1.6

Here's a copy of the slope/angle/percentage look up table.

Thanks for this guys, I'm going to see her today so I shall ask him to show me the money.
Or maths. :D
And Bob, no passengers on rough sections for me :)
Somebody has to guide me :D
Cheers

I have read a forum post by a South African guy who claimed he'd driven a stock Td5 Disco up a 38° hill at a military vehicle testing facility. No idea what kind of surface that is on.

I can take you to a hill behind Sellicks pub (south of Adelaide) that runs around 40 degrees and *is* drivable... ;)

I have a video of my old V8 disco going up it.... On laptop at home, will find and post...

Twitchy though - front wheels coming off the ground :o

It's behind the pub so I'm guessing that will be about 40 beer talk degrees? :) Given the usual correction factor that would make it 20-25° :wasntme:

Nope!

Never been to the pub!

Here you go:
[ame="http://en.wikipedia.org/wiki/Baldwin_Street"]Baldwin Street - Wikipedia, the free encyclopedia[/ame]
World's steepest suburban street is 19*, and appears to be open to 2 way traffic.

So for 18 degrees you don't even need low range... ;)

The steepest brisbane street is 17.4* http://www.brisbanetimes.com.au/quee...810-1immr.html

A few times I've attempted backing up a known 30 degree incline in high range reverse with my 300 auto and it won't climb. Foot to floor, full stall revs about 2500rpm without traction loss. I have the feeling the torque converter is starting to rotate the stator against the sprag with age and wear.
