Was ACC even available in an '11 or '12 Supercharged or Supersport? We've been casually window shopping since around September and have yet to see an '11 or '12 with ACC. Are we going to eventually find one, or are we going to have to expand our search to include the '13+ range?

 

I do not know for sure when ACC became an available option, but the earliest I can recollect seeing it on an XJ was the '16MY.

 

Yes. Adaptive cruise have been available from very begining. Here, from time 2:33, Top Gear presenter Jeremy Clarkson explains how it´s working on 2010-11 model :

Very funny

 

Awesome. Thanks! and great video.

 

Off the top of my head, I seem to recall ACC being a feature all the way back on the X350, and I've seen several '07- '09 XKs with it, so it's not like it was a '16+ option. I was just curious how common it was for the older X351s. And... if it's easily identifiable externally. Our '16 XJ has the big grill brick behind the badge so you can tell a mile away it has it. My XKR has the brick behind the grill, so you don't know it's there unless you get down and look inside the opening. I just wasn't sure if the first few years of the X351 had the brick hidden like my XKR or if it was front and center like our '16 XJ.

 

My 2004 XK8 (X103) had ACC. It worked "ok". The braking was pretty abrupt when it intervened. I can remember a few bowel stimulating times when it braked. Took a while to figure out the do's and don'ts while its active. Newer versions have to be better than that was.

 

Well, I was certainly mistaken about the availability of ACC, so this may be less than reliable as well, but it has always been my understanding that the Jags WITH ACC had a unique front growler badge (like a rectangle with the growler embedded in it) while the Jags WITHOUT ACC had the more common round growler badge. It was this idea, right or wrong, that lead me to believe ACC was only a later option as I only began seeing that rectangular grille badge in '16 MYs+. I know that my '17 XJL does NOT have ACC and mine has the round growler grille badge.

 

The X150, X350 & X358 all have it hidden; maybe others as well, but I don't care enough to go look it up. So going back to the original question... were the '11-'12 XJs available with ACC or not? If they do, is there a visible brick or not? If ACC wasn't available in those years, when was it introduced to the X351, and do all X351s with ACC have a visible brick? Am I not articulating myself here? I feel this is a fairly simple question, but we're going in circles.

 

It was available on x351 on launch date 2009. The radar was behind the front grille, not integrated on the grille like later models. You can see if it´s there by steering wheel control buttons of cruise control part. Non-ACC 2nd row have only Cancel, where ACC models have 3 buttons for + and - distance and Cancel. You can find this from 2010-11 handbook /quick start guide if you want to be sure. (sticky section)

 

We have ACC in our '16 Portfolio so I knew about the buttons. Thing is, almost every picture of the wheel in online ads fails to clearly show the second row of buttons and most ads do say the car has ACC. The few ads that you can clearly see the buttons (and also do say it has ACC) show non-ACC buttons. Basically, the only way to tell for sure is if there's a clear shot of the buttons (there usually isn't), or if there's a clear shot of the grill (always is). Additionally, the few that I have called to inquire about ACC have told me it does have it, then the requested picture of the wheel they send shows it doesn't. It's a real pain in the ***, and that's why I was asking about the brick. It's really easy to tell externally on the '16+ models, but I guess on the <'15's I'll have to ask for pictures every time I'm interested in what's listed.

I did find a thread that indicated adding ACC to a '16+ non-ACC car is just a matter of adding the buttons to the wheel and the brick/grill. I'll have to read a bit more about that to verify what I read was true but if it is, that does open up a lot of possibilities. I've already looked up the cost of those parts and they're within the range of what I'd consider money well spent if they're going in to the right non-ACC car.

Thanks for the replies; I feel my questions have been properly answered.

 

My 2011 portfolio has ACC. It's less aggressive when the gap distance is increased, instead of the "full Audi" lol.

 

If I increased my following distance here, I'd never get to where I was going because there'd be a constant parade of cars cutting in front of me. Utard drivers subscribe to the "if I fits, I sits" approach to lane etiquette, so even when it's set at the closest distance, I still will have to defend my place with a manual closing of the gap.

 

Parade of Audi´s?
That are true with ACC on multilane highways. You been cut and your car slows down to keep distance -> Driver behind you desided to overtake you because you slowed -> He cuts you and your car slows down to keep distance -> Circle is ready and rotating well.
Here X351 XJ are so rare that even the most used company rep fleet cars, Octavias ans Superbs, keep polite distance.

 

Both X351s and X150s are rare around here as well. It is interesting the different interactions the different vehicles elicit from admirers. If someone likes my Land Cruiser, it's usually something like, "sick rig, bro." In either Jag, it's "excuse me, Sir... do you mind if I take a picture of your car?" The next level up from that is Italian exotic ownership. I have a friend that's a bit of a collector... several bulls and horses, along with a mix of German and Japanese cars and a few really weird kei cars. He's said that when he's out in the GT3 or NSX, the conversations are always about the car, but when he's out in the 488, nobody cares about the car. EVERYONE knows what a Ferrari is; all they want to know who he is and what he does. "Just a guy" and "nothing of much global significance" are his answers.

 

When I step out of my '22 F-Type R, I always get..."Are you single?"

 

Maybe an F-type R is what I need in my life...

The x308 had an ACC light on the dash, but it was not an option on US spec cars, presumably in other regions though.
