Won’t be retro...

On a related note, the current RRS does *not* have an Active Locking Rear Differential option. What it does have seems to be an evolution of the Active Driveline technology first seen on the Evoque, going by the name of “Electronic Active Differential with Torque Vectoring by Braking”.

Maybe you lot are familiar with that already but I had to do some research on what the difference is. Basically there’s a clutch pack on each side of the diff which has the ability to lock the axle on that side to the ring gear. The focus is on going fast around corners but the system is equally capable of ensuring forward progress when one wheel has less traction.

It will be interesting to see which of these approaches LR takes for the Defender, and also whether they’ll be doing anything with the front diff as well as the rear.

The problem with buying a Toyota is that there's always a key item or accessory that's only available on the next model up ....


And as my non-car focussed teenager asked me the other day, why doesn't our $130k-when-new D4 have heated seats when our $40k-when-new Honda CR-V does?

My understanding is that they are two completely different systems with "Active Driveline" being used on the smaller models (Evoque and Disco Sport) and "Active Rear Locking Differential" (ARLD) being used on the larger models (L494/L405/L465).

The Active Driveline allows the AWD system to seamlessly move between 2WD (for efficiency), AWD and fully locked rear Diff. For the D5 you can get the ARLD by ordering the "Capability Pack", on the RSS and FRRR you get the ARLD when you order the a "On/Off Road pack" and is standard in the Dynamic models. The L465/L494/L405 are constant 4WD systems, never 2WD so, the while “Electronic Active Differential with Torque Vectoring by Braking” and "Active Driveline" do similar things they are in fact different in they way they go about it.

Active Driveline

A revolutionary on-demand driveline technology, Active Driveline can intelligently switch between two- and four-wheel drive as conditions demand, combining both the fuel-saving benefits of two-wheel-drive with the all-terrain capability of four-wheel drive. Four-wheel-drive is continuously engaged to provide large reserves of traction from a standstill, but a clutch completely disconnects the four-wheel-drive hardware when there is no tractive requirement. Should the system detect wheel slip or a more dynamic driving style, four-wheel drive is re-engaged within 350 milliseconds. Two electronically controlled clutches located either side of the rear differential distribute torque to the wheel with most grip.This improves the on-road agility while the rear axle can be entirely "locked" for maximum traction in very slippery conditions. Active Driveline's transition from two- to four-wheel drive is seamless, but drivers can monitor its operation via a dedicated 4x4i screen on the touchscreen display.

Active Rear Locking Differential

By monitoring vehicle and terrain characteristics, the Active Rear Locking differential can be constantly adjusted through an computer controlled actuator mounted on the differential, ensuring power is transmitted to the wheels with most available grip. This provides improved cornering stability on road and refined traction, with limited wheelslip, off road.

It’s confirmed, JLR are not targeting “oddball niche” existing Defender owners for the new Defender.

“JLR Australia is planning to turn Defender from an odd-ball niche player in the previous generation to a mainstream player generating serious volume for the brand.”

So not retro [emoji6]

I'm looking forward to the accessories coming out of the states like avail for Jeep.

Here's a pic from a L494 brochure showing the actuator mounted on the top of the diff housing.

So what system are you tipping for new defender

Not the Active Driveline. Whether they use the E-diff in its current for or something new I don't know but, I'm pretty sure whatever it is, it will be very effective.

Front and rear E diffs would definitely give it some ability.

Yep, No doubt E-diffs are more effective than purely braking of spinning wheels alone. I find a non ediff vehicle tends to "fight" against itself when traction control is trying to identify when and which wheel to brake to force torque to another wheel. When ediff is engaged, braking barely comes into it.
