My information is that the ACC is very rare on 2010+ XKs and XKRs. The quick way to tell is on the RHS spoke of the steering wheel there will be two control wheels instead of one. The ACC has two wheels. I too like the ACC and have and do use it on my XJR 575.
For the North American market, Adaptive Cruise Control was standard equipment on all 2010 XKR models, the first year of the 5.0L engine. ACC was also standard equipment on the 4.2L 2008 XKR Portfolio models together with the Alcon Performance Brake Package. ACC was an available option on other models for $2,200. Unlike the 2008 XKR Portfolio, ACC and Alcon Brakes were not standard equipment on the 2009 XKR Portfolio. ACC cost $2,200 and Alcon Brakes cost $5,000.
Models with ACC are easily identified by the two rotary controls on the right side of the steering wheel. Non-ACC models have one rotary control. Here's mine:
(I'm speculating that Jaguar hired the infamous Porsche " Options Elf ", in a bid to similarly increase profitability through utterly bewildering obfuscation)
Confirming my suspicions of a crafty Teutonic Options Gremlin covertly residing in Coventry, not a single ACC found; this after perusing essentially every online X150 XKR currently for sale, nationwide...
Actually, you also uncovered a few XKR coupes that I hadn't yet seen. Haven't been looking at XK's or (XKR) convertibles, which narrows the field quite a bit. Also, cars with interiors resembling baroque Ford minivans get a miss, even if the steering wheel pics are a bit fuzzy. My real focus is on '12+ XKR coupes...
And, tadaaa....a 2010 XKR coupe..multiowner but low miles...visually confirmed to have ACC (2 thumbwheels; RHS). Alas, seller is asking close to $40K, which I'm thinking is maybe $5 - $10K over market. I'm going to followup, though. Appreciate the lead...
Also, I've noticed in my casual shopping that lots of online dealer ads actually specify "adaptive cruise control", but pictures say not. Having called a couple of 'em supposedly with ACC but no clear steering wheel pics, I'm left with the impression that many resellers are simply cut and pasting option lists from somewhere, with little understanding of details. Only one dealer I've talked to actually knew what ACC was (and felt his car had it, until I asked him to count the thumbwheels). His ad still says ACC, BTW
Finally, off-topic I know, but XKR prices seem to be up appreciably, at least compared with my last look see a couple of years ago. Whether this reflects current used car inflation alone I'm unsure.
...ACC was also standard equipment on the 4.2L 2008 XKR Portfolio models together with the Alcon Performance Brake Package...
I don't believe ACC was standard equipment on the 2008 XKR Portfolio models. My 2008 XKR Portfolio coupe does not have ACC.
There is always the chance a previous owner could have replaced the ACC equipped steering wheel with a non-ACC steering wheel, but there aren't any sensors in the front bumper cover. A previous owner did replace the original Portfolio-spec Cremona wheels with Sentas. So anything is possible.
I stand corrected!
I reviewed my previous posts that compared the 2008 and 2009 XKR Portfolio models. Adaptive Cruise Control was not standard equipment for either the 2008 or 2009 Portfolio models. ACC was a $2,200 option in both years.
Only the 5.0L 2010 XKR included ACC as standard equipment.
Stuart, believe you are the dean of all things XK150. Compliments!
(Thanks to Ceejay, I've now uncovered a few ACC coupes; all of which seem to be 2010's. Still looking for an ACC 2012+, or a Portfolio like yours...)
Just because you liked a few of my posts doesn't make me "the dean". That honor goes to other Forum members who are far more knowledgeable than I am. What good am I if I don't have SDD and can't properly diagnose a problem? I'm just a hobbyist and Old School shade tree mechanic, which doesn't help much with today's computerized vehicles.
Guys, with your knowledge of ACC, perhaps you can enlighten me. Still confused after reading the manual.
I've got ACC in my '07, and on the open highway it's fine. But, often here in FL I just want to use it as a cruise control: Set a speed, ignore the cars around me (meaning don't react to them) and switch it off or on as I wish.
But ACC seems to wants to detect the car in front of me whenever I switch it on. I can't figure out how to make it run as typical cruise control. You know: set it for 80 mph and weave around cars, like the other drivers here do...(kidding). But here in Florida, reacting to all the cars cutting in three feet in front of me isn't a good thing.
Can anyone identify how to do run it like typical cruise control?
Interesting, I don’t have ACC, so took a look in the manual, and it seems that whenever you use cruise control, ACC is active. Doesn’t appear that you can turn that functionality off.

Yes, I read a couple of comments that effect. Can't believe it's true, because ACC can be a pain in the *** unless used in a lightly trafficked environment. It's really startling to have somebody cut in front of you within the sensor distance selection and feel the car slow down as it tries to return to the distance it thinks is right.

I'm not sure about the '07 model, but in my '10 XKR I know of no way to turn off the "adaptive" component of the cruise control. Any time that I engage the cruise control, the adaptive component of the cruise control kicks in.
One option to make it a little less intrusive is to set the adaptive radar distance to be at its shortest distance. This would at least keep the adaptive braking from "kicking in" except for cars that are pretty close to you in your lane, since it wouldn't be looking that far ahead. Not an ideal solution, but something to try.
I know that many folks on this forum have had issues with the ACC sensitivity on these models, but luckily I don't have any complaints so far. Most of the time I don't use the cruise control. But when I have engaged the ACC, I haven't found it to be overly sensitive to cars in nearby lanes. ** Knock on wood (dash) **
Good luck with your research! Let us know what you find.

Good tip on using the short range, thanks. Wierd design, though.
Anyone tried deleting the ACC from the car configuration file? Default to simple Cruise Control?

Adaptive Cruise Control (ACC)
