Right foot versus cruise control

I was doing 66 when hitting those 30s. Very flat. Sweet spot is definitely in the 60s somewhere.

The problem with our 2016 CX-5 in the hills as described above it downshifts to maintain speed but the real problem is going down the other side of the hill. If steep and/or long it throws on the brakes to keep the car from going too fast and you lose energy to heat. On my 2013 I could move the shifter to manual and it widened the range before it downshifted and I don't think it put on the brakes going down hill but I am not sure. Have not tried the M on the 2016 yet to see if the range is wider as the 2.5 has a bit more power and downshifting has not been as big a problem...
 
A diesel on cruise driven by a human will beat a petrol(gasoline) driven by a computer.

Haha damn stright!

7- challenge=accepted..uncongested Taconic parkway is the venue(maybe you've heard of it..Caddyshack?) maybe not but give me a number to set the cruise in D and ill beat it on the same exact route in very similar conditions (ill wait for b2b days with similar temp and wind direction/speed)with the the same or higher avg speed with the ol right foot (and hand) locking in 6th. What do i get if i win? Spoiler alert..haha jk man but seriously I will wait for the right b2b days and post my honest results..give me a hwy cruise number..

Cruise control always beats the feet. In some cars more than the others. In my BMW E91 the cruise control on long journeys saved a significant lot of money and it was apparent the moment you pressed the cruise control, the fuel consumption needle dropped (and this was a manual car with 6 speeds). The cruise control in BMW was very quick in responding to hills and slopes. The one in Mazda cx-5 is not that super responsive but does the job. You can feel the lag in cruise control response in mazda. And perhaps because of that or something else the drop in fuel consumption with cruise control in Mazda is not that great but it is there. With careful non spirited driving, I could challenge Mazda's fuel consumption with cruise control, but not so in BMW. It always beat me.
I must be one of those that hits the cruise control button as soon as I see an open patch of road even if it is not a high way. Driving is more relaxing that way. I am surprised that most people don't use it. I have a family member who never uses it because it is "dangerous".

Better to lose energy to heat than to lose $$$ to the heat.(five-0)

You like to coast downhill in the highest gear possible regardless of speed?

I personally love the way this CC slows down as well as speeds up.
 
Nice..i was gonna say Vb tix but seems they're in Eur for the forseeable..oh well..thur/fri it is, @70..wind will be more favorable going in thur but less so coming home vs fri same dir calmer and less favorable going in but light southerlies(more favorable) homeward...nothing extreme so should be a pretty fair test environment...32thur, 38fri. Results forthcoming...
 
The new MRCC will accelerate from standing start gently, maintain speed as needed. So of course the computer drives more smoothly than a human

The first car I bought with cruise control was in 1988. I loved it.
I have never owned a car since that didn't have it. Use it all the time.

My lovely wife however has never ever used it, ever. She's scared of it. No matter how much I try to encourage her to try it, she won't do it.
There are others out there like her. That's the way it is.

I hate driving behind someone on a highway that doesn't have or use cruise. Constantly slowing down and speeding up drives me crazy.
Always having to cancel or adjust the cruising speed on my car is tiring.
What I hate is when these people pass you, pull in front of you, and then slow down, forcing you to either cancel your cruise setting, or passing them in turn.
Back and forth, back and forth. Sometimes I think these people do it on purpose.
That's why I really like the adaptive cruise in my new car. Nice feature.
Cheers.

I don't think it does that. That would be dangerous. Is it autonomous braking?

Cx5 slightly hypermiled over bumps will beat cruise. But over very long distances its not worth it. My best on an office trip is 37.1
CX5 peak mpg is @ 30 mph 5th gear under light loads.
 
Agreed. If maintaining Same speed was not a necessity i cal climb up hugging my 6th but cruise will drop you to fifth or 4th.

my old 4Runner would accelerate up a hill like a bat out of hell, and it took a long time to back off of the accelerator on the other side. i never used it on back roads because i was afraid of getting pulled over for reckless driving and/or suspicion of DUI/DWI.
 
You didn't post your route, your average speed, weather, traffic conditions, tire pressure.
You also didn't post a result without cruise control on the same route under the same conditions.

Seems like a troll.

But I'm curious to know why you think cruise control will beat a human. If you think cruise control will hold a constant speed with less variation than a human, then I generally agree. If you're on perfectly flat terrain with no traffic and no variation in wind, then holding a constant speed should be better than varying speed with the same average. Because drag is proportional to the square of velocity, the extra fuel burned above the target speed hurts you more than the fuel saved below the target speed. But as soon as you throw hills and traffic into it, the answer is not so obvious anymore. In my anecdotal experience, driving on hilly terrain without cruise control, I seem to get better mileage by taking more of a constant throttle approach: gradually dropping below my target speed up hills and making it up on the downhills. Especially with turbo engines, using a lot of throttle to maintain a constant speed up steep hills seems to suck fuel quickly.

Word...
 
In hilly terrain I would certainly get better MPG just because I don't have to adhere to a strict MPH number. I usually back off gas going up hill and drop below target at top and then just make it up coming down. I think it has been proven that this method is better than maintaining constant speed thru the hill for MPG purposes.
 
Haha. Love it. Ok. 70.

UPDATE:
Well, first leg of challenge has CC the early leader in the clubhouse with a 30.6mpg @65mph average- this was 67 when I got off hwy but had to slow a few times- first a trooper on my six- (70 in a 55) then for left lane cloggers/dickheads cutting me off so a pretty typical day;)- rest of which was the 1 mile I go in town after hwy stretch.. Test conditions were 30F with a helping NW breeze @12-15 - I reset when I got on hwy which is ~7 miles from home so nice and warmed up. Homeward is traditionally the tougher leg with some elevation gain vs loss and typically head winds but they're supposed to settle to ~6mph. Tomorrow's temp looks identical, nice and sunny like today but winds lighter and less helpful on outward half and less hurting SW direction on the inward 9- so pretty close to a wash IME. I'm excited (and nervous) for the final tallies but can I just say that I fn hate driving with CC!!
