Cruise control
OK, so we don't use it, right . . . .
On my 14 Z51, it held the speed very well on the level and uphill. However, going down hill it did nothing beyond letting off on the gas to maintain the speed set. The result was exceeding the set speed by ever increasing amounts as you go down hill . . . not great!
My 2010 Ford cruise system is also good on the level and uphill. When you go down hill it lets up on the gas and then downshifts as necessary to hold the set speed downhill.
The question is: will my new (TPW 6/29) 2016 Z06 have an improved cruise control which will maintain speed as you go downhill.
The Corvettes are very speed 'insensitive', I mean that within reason you don't necessarily notice a 10-20 mph increase downhill on a highway. The problem is that LE is not likely to believe you were on cruise (at the speed limit) when they clock you at 10-20 over.
Anyone know what may be . . .

I drive an M7 so there is no downshifting unless I do it. But no complaints on the CC function. Throttle does ease off going downhill but I might have to brake if the hill is steep enough. Not aware of any changes for 2016.

The C7 cruise control does not downshift when going downhill and for the life of me I wonder why anyone would want that to happen? Enjoy and take advantage of gravity unless the hill is absurdly steep.
If the car gets going too fast for you, simply hit the brakes.
I am VERY pleased the cruise doesn’t downshift on downhills. I know how to control my speed w/o an overly intrusive cruise control. Don

Personally I have NEVER heard of ANY cruise control in a car that "brakes" to slow you down going down hill....if your speed goes UP, it lets off of the accelerator....that's it, to get your car to slow down, you use your foot.

Doubt it!

And you're getting a Z06??!!

My 2014 C7 with A6 will downshift going downhill with the cruise control on. While it doesn't hold it to the speed set, it does downshift as much as two gears...

Ex-LEO here. I will never forget the night I covered a traffic accident when a woman in a new Caddy missed a curve because she was going to fast. Her explanation, "I don't know what happened. I had it in cruise control and when I came to the curve it didn't slow down!"

I should know better but I had the same issue once when I forgot I had cruise control on and couldn't figure out why the Lexus RX I was in was accelerating into the curve without me using the throttle. I overshot the lane but luckily nobody was coming the other way. I didn't use cruise control again on roads with any reasonable curve in them.

set cruise control for a given speed, then using cruise control buttons, slow the set speed by 10-15 miles an hours, see if the car brakes to reach that new speed, many do, havent tried it in the C7 yet but will next drive
cruise comes in very handy in a high powered car, I use it to make absolutely sure I maintain a speed limit in the vicinity of police, don't want the car to creep up a couple mphs and an officer in a bad mood or a stickler for the limit pull me, esp in things such as school zones where tolerance maybe none

Thanks for the abuse . . .
When cruising down a 4 lane limited access for hours . . . . you relax your superior driving skills, enjoy the day, the scenery and use cruise to maintain a risk free speed. If you happen to be in an area that las long downgrades . . . the car will pick up substantial speed if the cruise does not just let up on the gas.
I gotta tell you, all I did was ask about a feature that I find very pleasant for everyday drinking as I live in a place that has highways with hills. Unlike the purists here, I enjoy just riding along at 'legal' speeds. Not every ride is max performance or total involvement.
Yes, I'm getting a Z06, and I'll enjoy driving it any way I want to . . . have a nice day

active cruise control on some newer cars, you can test if any given car will brake during cruise.

When you are in cruise (45mph) rural highway with up and downhill . . .it lets up on the gas downhill and if the vehicle continues to accelerate it will downshift to maintain the selected speed. Nice, and it saves brakes too, just the way the purists out there do . . . by downshifting on the hill.

My wife's 2013 Mercedes SLK350, my 2011 Mercedes E350 and my neighbor's 2008 BMW 650i all brake when necessary to maintain pre-set cruise control speed.
