HDC Variable speed

[CountyV8]

Hi All

Just picked this up from Facebook I take it via the cruse control buttons .

"Great day today at the Glanusk test drive proper off-road course, this time a lot of the overhead panel buttons worked as well as the diff locks, hill descent was a a eye opener as not seen it fitted with speed altering button before allowing you to increase or decrease descent speed."

"No it is the left hand button on the wheel, very intuitive and so effective"

I had that on my Mazda bT50.
With HDC on you adjusted the speed with cruise control buttons on wheel

Interesting. I have not heard much about the HDC at all but people have raved about how the truck will gradually walk itself down in 1-low.

New Landrover vehicles have it and my Amarok can be adjusted using the brakes or the accelerator. If I brake I can take it down to about 1mph when I let off the pedal or accelerate at I can make it go a bit faster.

I find it quite handy tbh, so will appreciate something a bit more refined on the IG

I put it in 4L 1st gear manual last Saturday on a damp slippery reasonably steep hill and feet off the pedals it drove slowly down at never lost grip at all.
That was in the diesel so really good engine braking
Vehicle behind me did it in 4H and had to use the brakes all the way down.

If you can do what the test pilot does at 20 seconds in , down a hill , I'm impressed. I'm not easily impressed btw.

Pretty damned impressive what that machine can do without all the fancy electronics it's replacement has today

Apart from the slowness and racket inside , I've never found my series 3 less than able!
When you consider where they took them across all continents , it's a testament to the engineering and robustness.

Wasn't it first introduced on the Freelander? It was actually a third party system (Bosch?) but JLR called it their own.

Tried it on a recent test drive with the grenadier and it worked very well no drones and creates like in other LR products

And all done with white collars and ties

The the poor guy in the back is bouncing around like a superball.
Mr. Bean would have put a chair on the bonnet and tied ropes to the wheel.

That is my recollection as well, since the Freelander had no low box. It's a neat system and one that is now on trucks and SUVs across the globe (including my GMC 1500). But, JLR's electrics are sketchy at best, so I am glad I've never relied upon HDC to get me out of somewhere steep.

HDC isn't that impressive IMO especially if you can drive properly to the conditions, HAC......well that would be fantastic IF the IG has it, I did hear it did at one stage but haven't seen or heard anything lately.

Yeah I posted on the the other day - the brochure says it has hill assist but I couldn’t see a button anywhere.

"Uphill Assist, meanwhile, automatically holds the Grenadier in position
after the driver releases the handbrake, and provides added safety when tackling steeper
terrain."

From the press kit April 22.

It had it, and was demonstrated, on the PTO2 that I drove at Floors Castle in Scotland a few months ago. To be honest I can't remember were the switch is but was clearly marked.

Thanks Eric, good to know

Up hill assist would be different from HAC as it doesn't hold it, it actively moves the car forward

Items for off road use are on the overhead panel. But when you want to find the photos you can't! But in respect of you first comment, I have had Discoverys with HDC for more than 20 years, and you could count on one hand the number of times I've used it because of necessity
