we know that the Rangerover and the Disco are very good offroad, but it all depends on the spec

Yes, if it has a Range Rover or Land Rover badge then it in off road spec. Everything is standard. Most 4x4 size tyres are a terrain blend ready for off road.

what exactly does the locking diff do, i thought it did as the name sounded and just locked the diff up.

But does low ratio do anything you couldnt do yourself just by being gentle with the throttle ?

Locking the diff does that. If you have an un locked diff and one wheel is off the ground (for example) What will happen is the wheel off the ground will spin and the wheel on the ground will stay still. In a locked diff both wheels will turn, providing forward movement to the ground.

In the situation where both wheels are on the ground and one wheel is wheel spinning, it can be thought of that that wheel is essentially 'off the ground' i.e. not providing any traction.



Low ratio - think of it like this you have a steep hill in front of you. You select 5th gear and try to power up - not going to get very far are you?

So you choose a lower gear, 1st. That's better.

How about a whole freaking low-range mode on the box? That's low range. Uber low gearing, makes ascending and descengin much easier.

Diff lock literally locks the two wheels together as if there was no diff. This increases traction as it harder for wheelspin. A normal diff means that when one wheel loses grip then its game over for the other wheel, even if it is on tarmac

why isn't all the oiling draining away though, the car's pretty much vertical

it'll be a sectioned sump - or whatever it's called, instead of all the oil draining to the bottom, it stays in sections - again - in simple terms, think of a comb but with the teeth much further apart, then fill them with oil, you stick it at 45 degrees, the oil will stay in the sections about half full.

at least - thats what i think lol.

I'd have thought a deeper sump with some baffles and bigger oil pump would be enough. It's not like the Range Rover needs the engine scraping the tarmac like the Jag it came out of does.
 
All the ingress and exit angles are done to the nth degree for bumper clearance so the engine will go through similar development. Admitadly not to that extreme!
 
Just got round to watching it last night and didn't think it was a bad episode :)
Not the greatest series but I don't think it was the worst.
 
It was an ok episode last week.

Kind of ironic making a big thing about filling the time though, seeing as pretty much the whole series has been filler.
