The fact that I am disappointed with the vehicle and hell will freeze over before I buy one doesn't mean I am not allowed to have an interest in how it works and the technology involved. Very Happy

The beautiful thing in this world is we can all have a different opinion and agree to disagree. Thumbs Up

Personally I can't imagine anything worse than owing and driving an old Defender, S111 etc but its horses for courses. As for the new Defender, its a great car but not worth the money and the D4 was a better all rounder. Eiger Grey MY23 D250 SE with bits. Known as Noddy.

What rubbish, this system has been around since the D3 IIRC, and works brilliantly whether you're on tar or off-road.

I didn't say that they don't work, just that I don't want a vehicle which has one.

You may have a different view but that does not make my statement "rubbish".

Let's remember that this is a well-mannered forum with no place for personal insults.

^ mate, no one is insulting you.

You are allowed to have the view that this tech is not for you, and I, in turn, am allowed to have the view that your view is rubbish. Laughing --

Actually, the system in the diagrams is not the system as the D3/4, RR, RRS had for so many years. I'd always assumed it is the same system in all L663s, but this is for the D6H (diesel 6cyl hybrid) and I assume for the hybrid LR had to eek out every last bit of efficiency. Schlepping around half a drivetrain all the time is not efficient. It is def NOT Haldex tho: Haldex refers to a self regulating system produced by Haldex for LR. This is simply a clutched system actuated by LR's electronics. Think of it as the same thing that Toyota uses in most of their 4x4s: switchable 4wd with no center diff when engaged. Only this system allows for slip as (speed) differential compensation. Much more advanced.

No differences. Only for the PHEV (plug in hybrid electric veh). Even the MHEVs (mild hybrid..) are the same as the rest and have LRs tried and true terrain response with a locking center diff. There is a vid on YT where an Ozzie Mag performed a test of 4x4 tow vehicles - guess which vehicle won. Wink I'll have a look to see if I can find it again and post a link if I do.

Does the new Def not use some variant of a Haldex unit? I didn't think it had a centre diff as such.

Haldex was only used for the baby vehicles: FL2/DiscoSport and Ewok. All the rest of the L663's aside from the D6H have locking center diffs. Not Haldex. And you can spec a rear locker too. Unlike the old Defender where the only options for the axle diffs are aftermarket.

I agree completely. I am always interested in newer tech too. And when you get stuck, please feel free to call one of us. The way the L663 is selling there will surely be someone not far from you to help you out of your predicament. If it is raining and/or cold, whoever helps you out might even let you warm up and dry out in their not leaky, not drafty new Defender. Cool

Hi Steve,
Thank you for the explanation,
but one thing is still not clear,
I have a d200, 3.0 mhev,
this is the encoding of my transmission:

EUCD-003 Transmission - Driveline
All Wheel Drive (With disconnect)

this is the coding of a defender 400 petrol:

EUCD-003 Transmission - Driveline
All Wheel Drive (Without disconnect)

from this it would seem that the diesel engine corresponds to the second part of the diagram, with disconnection. Shocked Shocked Shocked

Yes it’s only used on the D6H engines. Petrol engines and earlier non-MHEV diesels (the 4-cylinder ones) don’t use it.

my Car is a D6H,
from the ccf setting it looks like "driveline disconnect",
so i understand it the other way around....
sorry for the unclear translation.

As for the new Defender, its a great car but not worth the money and the D4 was a better all rounder.[/quote]

My friend recently sold his pristine late model Discovery 4 for a Defender 110 D250
ln fact his D4 was so nice, that l was going to buy it from him, but l needed a Commercial Vehicle for tax purposes.

His opinions will be interesting, l will ask him what he thinks. l know he loves the Defender but l've not actually asked him how it compares with his D4.

I used to have a D4 and loved it. Now I drive a New Defender and it does everything the D4 does, but so much better. I would never switch back.
