The Rover-Landers of BC

Interesting video about how well the traction control on more moden LRs works.



I'm not a "Jeeps suck" guy in any way, and the best, small off-roader I've had so far is a Russian Niva made by Lada (could go on ATV trails). Do TJs have difflock? If so, I wonder if it was on for this video.

Tootles,

Interesting video, thanks for posting...

Cheers, Andy

the Jeep is either in 2wd or 4wd in the transfer case, the Disco in the vid is AWD (might have had the diff lock mod done to the case) uses traction control to perform the way it does. The older Disco's did have the locking transfer case to make it awd or 4wd also with traction control in some years.

AWD is a vehicle that has only single speed transfer case (despite the marketing gurus miss-use of dozens of these terms).

Discovery, Defender, Range Rover and Range Rover Sport are more accurately described as "Permanent Four Wheel Drive".

AWD is best reserved for Audi/Subaru and any number of soft and cross over SUV's.

I stand corrected AWD and perm 4WD... Basically the same with the exception perm 4wd has a low range..
Either way, with out the diff lock engaged in the tcase or with out traction control helping... lift one wheel off the ground the vehicle is going no where in a rover with a lt230 tcase.. :roll: :lol:

Oh come on... There is no "official" correct definition. It is just a made up word that can mean anything you want it to mean.

As much as I shouldn't add fuel to this fire, here are some "official" definitions:

Web definitions

All-wheel drive. A drivetrain that employs a front, rear and center differential to provide power to all four wheels of a vehicle.

www.edmunds.com/glossary/

Short for All Wheel Drive. Power to all the wheels is controlled all the time. Sometimes a vehicle computer will switch the percent of power fed to each of the wheels but the drive system cannot be switched manually and so is always on.

www.comcar.co.uk/newcar/companycar/comcar/glossary.cfm

I can't find a definition that precludes a transfer case.

Not much fuel there I'm afraid :D Pretty generic and thin explanations....but its tough to be absolute on these terms due to the huge variations of drive trains and support hardware/technologies and of course marketing departments that well...don't even know what a 2 speed transfer case is or how many differentials a Part Time 4x4 would have compered to a Permanent Four Wheel Drive vehicle for instance :roll:

If you are talking Land Rover...then the "Official Definition" for the vehicles in question is "Permanent Four Wheel Drive" and if you think about it it is a very good definition.

Again I'm sure you can find somebody out there who is going to label a product with what they think defines it (auto journalist are famous for this) function.

If you want the correct manufactures term it is "Permanent Four Wheel Drive" :!:

with the T case locked you have to have one wheel on each axle spinning to go nowhere.

The Disco 2 did not have a complete locking mechanism except for 2004.
