Dmpoole Posted February 14, 2013 Report Share Posted February 14, 2013 Twice now when I turned on the cruise control, it turned on with Eco cruise. Every other time it turns on with Ecp cuise. Has this happend to anyone else and does any one know why this is. I have turned on Eco cruise in the settings. Quote Link to comment Share on other sites More sharing options...
DaveofDurham Posted February 14, 2013 Report Share Posted February 14, 2013 I prefer ecocruise. I have also noticed that sometimes I turn on cruise control and it is not in ecocruise mode even though I feel certain it was in ecocruise last time I used it and I didn't turn ecocruise off.

Dmpoole Posted February 14, 2013 Author Report Share Posted February 14, 2013 This is the situatiion that I am referring to. I can not figure out why the cruise normally turns on with eco, but twice it has turned on without it. Quote Link to comment Share on other sites More sharing options...
Tjfirebug Posted February 14, 2013 Report Share Posted February 14, 2013 is your cruise set over 62mph? if so the eco will not turn on. that part is bad when the freeways here are 65mph.... Quote Link to comment Share on other sites More sharing options...
Dmpoole Posted February 14, 2013 Author Report Share Posted February 14, 2013 No, I was setting it at 50 mph Quote Link to comment Share on other sites More sharing options...
ptjones Posted February 14, 2013 Report Share Posted February 14, 2013 is your cruise set over 62mph? if so the eco will not turn on. that part is bad when the freeways here are 65mph....I have used ECO cruise at 66mph, I will check it again. djone110 1 Quote Link to comment Share on other sites More sharing options...
eidtelnvil Posted February 14, 2013 Report Share Posted February 14, 2013 I've had it enabled at 70mph, and was getting around 35-45 MPG. I've never had it turn off based on speed. Quote Link to comment Share on other sites More sharing options...
valkraider Posted February 14, 2013 Report Share Posted February 14, 2013 Eco-cruise has nothing to do with the 62mph. Eco-cruise works at any speed. The 62mph is the limitation of the electric motor in the Hybrid model C-Max (The Energi model can go up to 80 on the electric motor due to changes in gearing and computer programs). Eco-cruise is simply a setting which makes the cruise control try and optimize for fuel efficiency. It doesn't change a lot that is directly noticeable to the driver. It may, for example, not try to aggressively maintain an exact speed in Eco-cruise such that when you go up and down hills it would let the car slow a little more and not accelerate as hard to keep the set speed. It may be more prone to try and regen when in Eco-cruise. Etc etc... What you will find, however, is that over 62mph you do not have your all electric motor available and as such the ICE cannot shut off. This is one small reason why the EPA highway tests which are only 11 miles long and average 48mph and don't go over 60mph are not accurate representations of real world. Even the "high speed" EPA test averages around 48 and only goes over 60 a couple times for really short spikes. Since Ford set the electric motor to be able to run up to 62mph it really is optimized for city driving and not true highway driving.

wab Posted February 17, 2013 Report Share Posted February 17, 2013 I wonder if we could get eco-cruise for our 2012 motor home :drool: .The cruise works extra hard holding the set speed.When that V10 drops down a couple of gears and goes WOT.. ouch on the MPG.It even does it on TX. hills. wab Quote Link to comment Share on other sites More sharing options...
MacGyver Posted April 21, 2013 Report Share Posted April 21, 2013 FYI I've seen all electric up to 63-64mph with an almost fully charged battery and a level to slight downhill. Quote Link to comment Share on other sites More sharing options...
