I see they make a point of stating that the new Octavia 4x4 estate has EDL on both axles. Does the Yeti have it that way too?

Wouldn't it be useless without it......

I know it's often difficult to interpret, but the Yeti manual says: "If one of the wheels starts to spin, the EDL system brakes the spinning wheel and transfers the driving force to the other wheels." Note the use of the plural at the end there.

Actually the more I think about it the more I think that the author of the article doesn't seem to understand what EDL is. They write about it as if it was a real differential really being locked. It's not, it's a bit of electronic trickery that brakes a wheel if it spins when torque is applied. The clever drive system then sorts out sending the right number of torques (to borrow a Clarksonism) to the other wheels, same as it does when EDL isn't intervening. [OK, that's probably an over-simplification but I reckon it's essentially close enough.]

Bear in mind that the article also states: "...that much grip should translate into excellent stability in the wet or the snow." As any fule kno (especially if they peruse these forums assiduously) a-FWD-with-winter-tyres-is-better-in-the-snow-than-a-4x4-with-normal-tyres.

So I diagnose an ignorant journalist or, being generous, trying to cram too much 'information' into too few column inches at the expense of accuracy.

Hence I asked the question! I knew it was electronic hence it being called an EDL. But the way the article was worded it made me wonder.

I suspect that the author has misunderstood what and how the EDL system works.

Any vehicle with a true diff lock on either axle can be very difficult to drive, especially around corners, as they want to go straight on!

Jez, not really. The old Series LR's didn't have a diff lock as standard and they took some stopping off-road!

Yeah that's what i was thinking i.e if you have a form of differential lock, that didn't apply to all wheels it wouldn't be that useful...:-)

In my opinion they don't quite get it.

It's probably got a similar system to the Yeti where wheels that spin are braked, which transfers power to the other wheels.

So as the power can be transfered to any wheels on any axle it seems that they have decided this is EDL on both axles...

On a few other points raised...

The utility Land Rovers didn't get any form of diff lock (except the centre one) ever, other than a traction control based system (like we are talking about) that was introduced to some models around 5 to 10 years ago. They managed fine like that.

Also a locking diff is a PITA whjen cornering, but a lot of "locking diffs" only lock under power meaning driving round corners is no problem.

But this probably isn't the place to be going into the differences.

But useful info anyway.
