When I bought my Range Rover Sport SC it came with the brand new feature of Adaptive Cruise Control.

I found it irritating, as there was no option to have a standard cruise, it was all or nothing. The system wasn't very intelligent, if it spotted a car in front it would brake the car quite hard and would not accelerate until the obstacle was out of the lane in front. Sometimes it would detect the trailer of an HGV on the inside lane to you, and mistake it for being in your lane, and brake! AARRGGHH. Drivers behind must have wondered what the hell was going on. I felt like it was being tested on me and I had paid a princely sum too.

When I found out the SC AB had it I was a bit dismayed, but having tried it on the M1, where cruise control is mostly impossible to use, I've been really impressed.

You alter the gap distance as before, using the paddles under the steering wheel on the left hand side, and it shows it on the centre dash (One of the few things the centre dash does show you). So you set the speed and the distance you want to maintain and the car will continually assess the car in front, the speed its doing, and will slow you down but gradually, and also speeds you up too.

It's much smoother and more relaxing and just does what it should do, without drama. I'm now pleased I have it.

I'm sure none of this is news to many but they definitely improved it.  Discovery 4 HSE

I experienced it in my test drive of the new sport. It's wonderful. I liked how you could adjust the gap in front. I even tested it following a car as it pulled up to a junction, I let it brake us to a standstill.

I am the complete opposite. I prefer the early ACC. Could not get to grips with it in the new RRS, although, I suspect that may just be down to my driving style

Im a fan on long motorway journeys but it could be improved if you could adjust the rate of acceleration back up to the set speed as often I find it too harsh back up to speed. How do you find it in the SC ? does it kick down to get back up to speed as quickly as possible ? 2021 P400 Silicon Silver AB

It varies to be honest, I pulled away from a junction and hit "Resume" and it slowly built up the speed, and then started to get quicker later on in the cycle.

It can certainly be brisk if it drops down to say 60mph and the cruise is set to 80mph, it doesn't take long for it to cover that! Discovery 4 HSE

IIRC these settings can be adjusted with the right tools

One big advantage would be reducing the shortest distance as it reacts quicker than a human you could sit a bit closer to lorries and the like for improved MPG but the next advancement of it is going to be fun! where it talks to the cars in front fitted with it so could in theory sit a metre or less away from the vehicles in front in groups of 5-10 and then if the car in front detects an obstacle a message is sent to the vehicle at the back of the group and it then responds back saying is braking so the other cars can start braking. its freaky to think about but to the human eye they all brake at once and with all the eletronic braking aids available brake very quickly when needed....
All the manufacturers need to do is agree a comm standard between the vehicles thats secure (no like the VAG key encryption standard...!) and is quick and make it opensource so no licence needed  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

What possible advantage is it to drive a metre away from the car in front regardless of system's?

PS: We all saw your video remember

Which video The Golf driver who i later found out got a telling of from the police :p

And dont forget the 2 second rule is good but if the cars are doing the thinking and braking then you can afford for them to that close together...
Dont forget, an FF will be able to brake better than the quoted braking distances in places like the highway code and once the thinking distance is almost completely removed you've gained at least 1/3-1/2 that distance back.



I cant listen to the sound but i dont think the a disco had abs, but also shows what cars were like 10yrs+ ago never mind more modern cars that would be fitted with such systems... FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Seriously?

Is this your other car?

Nope, although i have driven some cars with very low CD's


According to LR buyers of new range rovers are very driven by economy..... I did point out that i thought when they were spending £80k+ on a car they usually wouldnt give a stuff but be more bothered by their tax liability on it  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Sorry but distances need to increase not decrease. Bigger the distance the less red brake lights.

In a steady flow of traffic safe distances make no difference to travel time.

Its the idiots that speed up to three inches from the car in front then brake heavily when they don't move out of the way that cause the traffic jams that equal the longer travel times...

Very true Gaz and i often enjoy the inside lane for that simple fact tha i can sit at 56mpg without much issue and at the safe distance or a little less without issue.

I am however saying that an automatic system could do this much better than a human and with less aggression/incident and improved MPG and reduced mechanical stress.

Im one of the types that uses 1st/2nd gear in traffic to crawl upto lights that are red as it
1. adds another impulse to the sensors for the lights
2. the engine would idle for a little bit anyway so why not use the energy and engine brake first and then crawl
3. the light is red so why rush upto it and stand still?!? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

How do you steer if you are 1m behind a huge Artic? You just have to follow blindly and hope he goes where you need to go...

It looks like I'm one of the few who does not like the ACC function. It's OK on motorways (ish) but I found it would go into panic mode on autoroutes/autobahn when rapidly approaching a truck on a curve. It would also slow the car down imperceptibly when catching up a slightly slower vehicle and having latched on you suddenly find that you are travelling 20 mph slower than planned as they slow down too. I suppose if I set the gap to a lower distance it would be more noticeable.

It is no use on urban carriageways when there is street clutter or cyclists either, not much help when you want to use the license saving facility.

Thankfully I now have ASL on the L405. 2019 D5 HSE Lux SDV6 Indus
