With my FuSpo, I'd say Fuel Mileage is on par (maybe slightly better) than what I expected. Took a mini 600 mile road trip from Long Island to Lake George over the weekend. A little over 2k miles on the car now.

Around 75MPH +/- cruise control most of the way, I averaged about 26.5 MPG.

The only thing I'm not fond of with cruise control is the Engine Braking at exactly 5 mph over the limit. Wish there was a way I could change it to 10 MPH over the limit.

There were too many quick ups and downs on the hills and I feel I could have gotten slightly better gas mileage with a 10 MPH over set speed. For instance, car performed some engine braking down a hill, but it had to punch the gas 5 seconds later to go up another hill. If there was a 10 MPH limit, the car wouldn't have had to punch the gas to go back up the hill.

I guess I could have turned cruise control off, maybe it's just not meant for the hill-type scenario I was in. Though, I wonder how ACC would have fared in this situation.

I know what you mean, and it is annoying to me too. I get why they do it, and I do like it at certain times, but you do save a little more fuel by just letting the car speed up down the hill so you have to accelerate less. I tested this a while ago with my Focus, and got noticeably better MPG (about 3-4MPG) by NOT using cruise control.

I wish they let is change it as well - 5MPH for traveling on holiday weekends when the cops are ticketing, 10MPH for the rest of the time. That would be great!

I found that my adaptive cruise held the speed to within 1mph up and down hills. It was a bit weird at first feeling the car use downshifting, engine braking and application of the brakes to hold speed on steep grades, but it worked so much better then the hill decent programing from years ago.

Wow is yours really that accurate? And you mean without a car being in front of you, I'm assuming, right? Radar cruise is the one thing I wish I had, I just didn't want the entire package with the irritating front park sensors.

Living in Colorado we do a lot of mountain driving. And the engine braking and downshifting is really noticeable. I think it keeps the car to within 2-3 MPH of the cruise setting. No question you are giving up some MPG from less coasting on the downhill. But in mountain driving here, it is a lot of work and thought to keep downhill speeds from throwing you to a firey death off the side of the mountian. So I appreciate the car taking that chore over. No worrying about overusing and overheating the brakes, etc. And if the tranny wears out, well that is what the extended warranty is for.

I just moved to Littleton and I can say the cruise control has saved me on tickets. Without cruise control I can wind up doing 50 in a 40 just from going down a hill. Didn't have to worry about that in Florida :)

The front parking sensors are part of the enhanced active park assist package. I actually wanted the front sensors for parking and made the mistake of thinking the same thing.

Interesting point, which was my other concern. Tranny/engine wearing out due to Cruise Control. There's no disclaimers anywhere for excessive wear using Cruise Control (at least my skimming the manual didn't see any), and you'd think the auto manufacturers wouldn't put this "feature" in the car if harmed it. It does sound like one of those things that will wear over time, just adding more strain for right after the 5 year power train or 8 year ESP mark hits.

I mean, jeezeee. Some hills I was hovering around 4k RPM.

I suppose bottom line is just to not use it excessively on hills. I feel like I'd rather pump and wear the brakes, since those are cheaper to replace down the line

It was throughout my long trip in the mountains and plains of Colorado, Wyoming, Utah and Montana. I think it helped that I was running 65mph+ so that the engine was producing good power in 6th gear. I am sure if I was lugging it, some speed loss would occur prior to the car downshifting and regaining the set speed.
I found the braking effect really accurate too on long downhills, whilst the transmission smoothly dropped gears to help.

Honestly this has been the most accurate and enjoyable cruise control I have ever used.

Interesting... that's another thing they changed from when I pre-ordered mine. I could get the Enhanced Active Park Assist package separately, but if I got the Driver's Assist Package, it forced me to include the EAPA package as well while we put my order in. Oh well.

Funny you guys mention this, I'm sure it won't do any major damage, but I still just feel bad letting the engine brake the car down hill for a long period of time. In my Focus, being an older system, that will kind of jump between minor throttle and engine braking quickly on small hills giving a weird feeling throughout the whole car. Now that really gets me worried something's gonna break, haha. At least our Fusions are better at it.
