Thread: Range Rover Velar

Almost identical chassis dimensions to the FPace but the boot is bigger and the body is slightly longer, although it is also lighter than the FPace with a lower GVM. The ground clearance is identical with coils but the air sprung version of the Velar is higher.

They both have the tiny little 66l fuel tank but maybe it is bigger on the more powerful versions of the engines.

I think the Velar has the D4 type centre ediff but the FPace has a different one with drive biased to the rear.

The Velar has the same rear biased with on demand 50/50 all wheel drive.
The Velar also has the rear e-diff as an option

Justin,

This is what I read in the brochure:

"Uniquely developed to meet Range Rover Velar’s requirements, the highly durable transfer box uses an electro-mechanically activated multi-plate wet clutch to deliver smooth and precise distribution to the front and rear wheels. This ensures the constant optimisation is imperceptible from the cabin and available engine torque is maximised to give efficient vehicle traction. IDD determines the required distribution by continually monitoring the vehicle and its interaction with the road.

Typically starting with a 50:50 distribution to ensure maximum controlled stability from the first vehicle movement, the system has the full capability of 100 percent rear bias to 100 percent front bias should road conditions require it. Predictive, as well as reactive, the system helps prevent losing traction as well as working to regain it."

This starts at 50:50, which is different to the FPace brochure, which makes a point of the rear bias and can get up to 50:50 when required. To me, this looks like a diff (50:50) with the clutch pack lock up like the D4 transfer case but the FPAce is some different sort of system, possibly Haldex or something like that.

I could be completely wrong, but that was how I read the above.

That is different to the one I read that stated it was 100% rear and would dial in up to 50/50 front/rear as required.. I will see if I can link that one for you

Here is the FPace version:

"The F-PACE All Wheel Drive (AWD) system delivers confident handling on most surfaces. At its heart is an extremely fast-reacting, compact transfer case with integrated Intelligent Driveline Dynamics (IDD) software. Exclusively developed by Jaguar, the unique IDD software features sophisticated algorithms designed to react intelligently to road conditions for traction on demand. Whenever greater traction is needed, IDD is designed to transfer the right amount of torque to the front wheels - a process that takes no more then 165 milliseconds. Offering a smoother drive, the system also consumes less fuel and has lower emissions than permanent AWD. Predictive, as well as reactive, the system helps prevent you from losing traction instead of working to regain it5. On F-PACE derivatives fitted with Adaptive Dynamics*, the Adaptive Surface Response (AdSR) is designed to recognize differences between surfaces to exploit the maximum available grip. Drawing on the unrivalled expertise of Jaguar Land Rover All Wheel Drive systems, AdSR constantly monitors the car's environment and adjusts the appropriate engine and brake settings5. Once selected, AdSR works to support you in adverse weather and across most challenging surfaces."

The diagrams show normal 90% rear and 10% front but it can also get 90% front and 10% rear if the rear has low traction. This is the same principle as a Trutrac limited slip diff so it probably has something like that instead of a locking diff, like the Velar.

I just tried to find the site I read it, but couldn't find it again. I found some that said rear e-diff is standard and others say an option, so no trusting anything these days!

I did find this on the LR brochure

"the highly durable transfer box uses an electro-mechanically activated multi-plate wet clutch to deliver smooth and precise distribution to the front and rear wheels. "

"IDD determines the required distribution by continually monitoring the vehicle and its interaction with the road. Typically starting with a 50:50 distribution to ensure maximum controlled stability from the first vehicle movement, the system has the full capability of 100 percent rear bias to 100 percent front bias should road conditions require it. Predictive, as well as reactive, the system helps prevent losing traction as well as working to regain it."

It is the same system the F-Pace has, but starts off at 50:50 instead of 90:10

Most of the current RRSs have no low range. I rarely use low range, instead use TR, torque and power to get me through particularly on the beach.

The FL2 and Evoque are ok in many off road situations where reasonable traction is required. The Velar sounds more advanced than those. Basically it sounds a cheaper equally capable vehicle than the RRS without low range.

Justin, you posted the same thing I did!!

Anyway, they are set up differently by whatever means LR uses, but FPace only gets a max of 90:10 whereas Velar gets 100:0 if required.

Re the Velar being a possibly more capable car then a RRS with no low range, don't forget it only weighs 1829kg as well, with the same 700Nm diesel available and adjustable air suspension, so it should go really well in sand, if anyone actually uses it like that. It also has an optional rear ediff, which the RRS doesn't seem to get any more.

We'll have to wait for Gordon to get one to try out its 4WD ability when he replaces his RRS or maybe his D4!!
