Adaptive Cruise Control

[jjsea55]

After a cursory review of the model center's portrayal of options and features, it would appear that adaptive cruise was offered as standard on base models but not on the V-series. Could adaptive cruise even be optioned on the V models? What was the thinking behind its unavailability on the V-series?

There is not enough room for the 'radar unit' on the V; the supercharger intercooler and transmission cooler take up the room on each side of the lower mesh grill.

Thanks, cubby558! That explains that. I'll take that trade-off in a flash... I'm not sure how advantageous the adaptive cruise would be to my driving style, anyway. It is an interesting concept, however.

I will have to say the acc is a really really cool deal. The V is cool but I wouldn't give up the acc for it.

And some nice parting gifts as well...

For most of the Interstate driving that I have done, the ACC seems to work well. I find it to be one of the more interesting features of the car.

Perhaps I should consider it a nice "consolation prize" for a non-V car?

I have to agree... I wouldn't give up the acc to own a V, either.
It's one of the coolest "options" on the base XLR!!!

acc

When I take my yearly summer road trips thru Idaho, Montana I` m not in a hurry so I use the acc. Going thru the mountains curves with the steel guard rails the acc would come on in the begining of the curve and go off half way thru the turn. I wouldn`t have to do a thing but steer. I was going thru a really, really tight turn, almost a 270 degree corner on a switchback, when the acc shut off saying " curve too tight" Speed was set at 55 mph. Another time, coming into a town I had the acc set @ 65, following a pickem` up truck. The truck slowed down the acc to city speeds and I went until the second stop light @15mph before I had to hit the brakes. Pretty cool system. The only problem is, on curves where the set speed is safe, the radar beam would hit something off the road and slow the car down when it is not needed.

Would've been great if some "technological advancement" had developed a more streamlined ACC unit for adapting to the restricted space we V owners apparently have. I think I would've really enjoyed applying it when the opportunity presented itself.

I've also noticed in reviewing interior photos of some of your XLR's and others that the interior adornment is a significant step up from most V's. It appears to me that the trim and paneling options were greater for the Base/Platinum versions of the XLR.

Having said that, I knew I wanted the V for the even higher exclusivity factor within the complete XLR realm. Numbers I've seen revealed that only 13% of the six year XLR production bore the V insignia. She's also pretty lively when you need that "little something extra" : )

Clearly, ALL XLR's are truly & significantly captivating!

The STS ACC is mounted behind the Cadillac emblem in the center of the front grill and available on the base as well as the STS V. I wish they could have done that for the XLR V as well. It is a neat feature and I was disappointed it did not come on the XLR V. I also like the automatic headlamp dimmer feature on the STS which was not even offered on the XLR.

Could the STS ACC be adapted to fit in the grille of an XLR V?

I thought this was an ACC-related thread. After Tyrones's threadjack, it should have been re-directed to a new thread. Threadjacking makes it very difficult to find info later on.

I have a question about the "Distance Setting" of the ACC.

Does the ACC's computer adjust the spacing between me and the vehicle I'm behind for different speeds?

In other words, if I've set the distance for as close as it will go, and say that distance is 4 car lengths and I'm doing 40 mph, and we increase to 70 mph, and my ACC is set to 75 mph, does the distance increase to 7 car lengths?

While on my road trip last year, I was 'Drafting' trucks and when they slowed down to 40 mph it seemed that I was closer to them than when we were doing 70 mph. I know that's only 3 car lengths difference but the average car length is about 12 feet so that's 36 feet or 12 yards.

I've searched for this answer since my return from last years trip but haven't been able to find it.

From my perspective, I haven't noticed what you are talking about. My ACC keeps me about the same distance behind the car in front of my no matter how fast I am going. The distance doesn't change if I am going 35 or 70, the distance behind the car in front of me is 3-4 car lengths at the closest setting.

This is good question! I do know when driving highway I usually end up setting it closer because if its set to like 7 cars it stays back then cars slip in between and ends up slowing the car down! I believe it does seem to stay back more car lengths at higher speeds, but not sure!

I hope this question isn't hyjacking the thread, but does the XLRV have normal cruise control?

Yes, indeed.

 

[madcurl]

Yes, indeed.

Thanks. IMHO, the ACC is a really nice option for you'll never run into the back of another car if it's engaged. On the other hand, if you live/drive in areas where there's tight turns on the hwy; then ACC isn't on the top of your list. You'll find that the computer is actually driving the car for you and when you're entering a turn and there's a large object in front of you headed in the same direction (like a big rig), but on the side; the system will automatically slow the XLR down. This also happens if the radar senses of guard rail too (sometimes).

Like I said, you'll never run into anything while the ACC is on, but you'll have to get use too (it) wanting to apply the brakes, so I've found out that as I approach a truck on my right I have to be nearly kissing the white line on the driver's side in order for the ACC to not engage. This feature is nice, but not when some else is behind you (like another big rig) as the both of you are passing a slower truck and suddendly the ACC wants to kick-in. Me? I've gotten use to it so I manually have my foot on the gas. Also, it's cool when you adjust the distance. A icon pops up (looks like the silhouette of a XLR) viewed on the HUD. The sound from the stereo system is reduced as a loud peeping sound (with red flashing lights) warns you.

Maybe you should have your ACC checked out by a dealer ... I rarely find the ACC indicate an object when I go on curves on the interstate ... if the turn were tight enough, yes, it would show the car in the other lane (but then those are usually too tight of turns to have the ACC activated anyway). I didn't like it at first, but over the last 4 years I have really gotten to like it. I never have a problem of the sensor picking up a big truck next to me when I have it on, I pass without a glitch. Maybe yours needs to be slightly adjusted.

 

[Crimson Pearl]

My experience with ACC is pretty much like ChicagoDave.

I find it to work well with minimal problems. I only use it out on the interstate highway when traffic is light.

I expect that I will be using ACC on the way to Bowling Green.

Another ++ for the ACC, it sees in the fog!

A couple of years ago, while going east on I-40, early in the morning doing 75 mph with the ACC ON, I found myself suddenly in a fog bank and before I could tap the break to turn OFF the ACC, it detected vehicles in the fog that I could not see at all and matched their speed.

I was close to the eastern border of New Mexico, and it was the first time I'd ever seen fog in the middle of a dessert!

The only Negative thing I have found with the ACC is I get so use to it that when I go on a trip in one of my other two vehicles that have normal Cruise Controls, they don't match the speed of the vehicles in front of me.

The only improvement I'd like to see on the ACC, on any brand of vehicle, is it should be connected to the Emergency Flasher system and activate it when the ACC has to slow down so as to let others behind me know that I'm slowing down.
When I know that my car is going to slow down and there are vehicles close behind me, I hit the Emergency Flashers instead of tapping the break to turn OFF the ACC to let them know I'm reducing my speed. And of course, as we settle down to the reduced speed, I turn OFF the Emergency Flashers.
Of course this all depends on traffic and driving conditions. That's where the HUMAN FACTOR comes in!
