Now that I got your attention :) it would appear from Fuelly.com CMAX Average MPG results that alot of CMAX drivers aren't driving their CMAX's the way they were designed to be driven by breaking the 2 Bar Acceleration Rule. :drop: To get the best gas mileage you need to Drive using the Empower Display 2 Bar Power Acceleration Rule where the ICE runs the most efficiently and charges the HVB the fastest.  

Empower 2bar

 When driving  you can use a mild Pulse and Glide strategy by accelerating at 2 BARS to around 5 mph over the speed you want to cruise at then let off of the accelerator for a second to allow EV to engage then back on to maintain speed until HVB SOC gets low enough for ICE to start then accelerate at 2 bars to 5mph over and repeat.  :)  This is worth atleast 2 MPG's and probably more. :yahoo:

BTW covering up the grills is worth another 2-4 mpg. http://fordcmaxhybri...ng-2-5-mpg-gain

 

It would be nice if members would comment on their results.

Happy CMAX Motoring :)

 

Paul

sorry.. :( i'll do better. LOL

 

The hiway I drive on everyday about 16 miles one way to work, i can get 3-6miles on EV only depending, small hills and uphill on ramps both way to and from work, so that kills the mileage getting up to speed. :( 

 

 

thanks for the tips!

So that's how the Niro got 76 mpg!  :lol:  :stirpot:   As for getting 2 bar accels, I love using Eco CC for an automatic "2 bar burn".  If a CC speed was already set and then you stop, you just accelerate manually to 20+ mph, tap resume and Voila, the car goes back up to speed at 2 bars (or close, depends a bit on set speed, I think).

...  To get the best gas mileage you need to Drive using the Empower Display 2 Bar Power Acceleration Rule where the ICE runs the most efficiently and charges the HVB the fastest.  ...

That's a good summary, and timely reminder, of the approach I learned at first, and it's good advice, as far as it goes. 

 

I use it as an upper limit, depending on traffic and terrain. I gained quite a bit by reducing it to 1.5 bar, after watching RPM (MyView). When I could keep RPM below 2000, fuel use seemed slower. The side benefit of the slower acceleration was that the HVB had longer to charge before I started cruising in EV; win-win!

 

But it does take patience. And you need 2 bars on the highway - depending on traffic and terrain. 

 

Of course, I'm also not in Paul's mileage league, especially on the highway. This is what worked for me. 

 

HAve fun,

Frank

Adding to fbov 1.5 bar thoughts

 

I have used the 2 bar rule with success but for the last few months I have been mostly driving so I get the highest speed to get regen when the gas is on or else I coast.  On the highway I estimate like 51 mpg though it is hard to say for I was doing a mixture of highway and suburban.  So I am not speed limiting or bar limiting but regen limiting.  I was surprised to get that high mileage on the highway for the motor runs a higher percent of the time compared to the 2 bar pulse and glide.  When it is at this highest speed to get regen the engage screen shows no EV use so I kind of assume electric generation equals electric use.  

 

This highest regen speed means going up some hills when starting from a slow speed means a 1.5 to 1.75 bar acceleration.

 

I use this when I am by myself in the car.  It is a game I play and generally don't subject others to the full version of it.

 

If challenging myself to get good gas mileage wasn't a game I play I would use the heater more.  It really doesn't take that big a hit.

 

My trip meter I am kind of using as a lifetime-like meter has 11K miles on it with 53 mpg.  ( Though it now shows something like 1000 miles on 200 gallons for it does not display the 10Ks )

 

My lifetime is 47.4 though now most of my trips are short and with the cold I am frequently below that.

The Hybrid Game!

The Heroic Happy Hybrid Hyper-miler Game!  I've started wondering, though, will I miss it with a BEV?  (I do hope to have one....some day.)  Or will I enjoy not "worrying" about when to run the ICE, and all that stuff?  Yes, there will still be techniques to maximize mileage, but it seems it will be a lot simpler.  (The drive-train will be a lot simpler for sure!)  So, will you miss it or be glad its gone?

I've been working a bit on the pulse and glide. I stick with the 2-bar rule, but in Northern VA you can get pushed off the road if you don't dip into 2.5-3 at times.
Currently at 44.5 with grill covers. I get stuck sitting in lines a lot and I love my heat so I get a fair amount of idle time.
I was at 45.5 but then had a few cold days (8-20) and dropped to 43.

Good tips here.  One other one that I learned from this site is fast acceleration if SOC is high.   If I don't need to charge the battery then getting to the max speed I want to go fairly quick work well.   Less time the ICE is running.  Then just a light amount of battery to let the car coast.   This doesn't use much of the battery charge but the drop in speed as you coast is not too bad.

If you can block the top grill and tape around the center Grill Cover that will help to keep the cold air out of the ICE compartment. Oil pan heater isn't a bad idea to preheat the ICE and insulate it. :)

I thought about blocking the top off too but I think I will save that for when we don't have 60 degree days after a 20 degree day.
When you got that temperature alarm did your temp gauge move above half way (gradually) or was it all the way to red? I guess I'm really asking if you monitored it before/during/after

IIRC the Smart Temp Gauge starts moving up when the WT hits 226*F and slowly moves up to 246*F, top line and alarm goes off.  I want to impress to members this is very hard thing to accomplish, it can only happen when you are going on a very long uphill climb and easily corrected  by letting off the gas. The two times that this has happened to me it startled me and I instinctively let off the gas. When this happens you have at least three  options, first turn on heater full blast, temps will drop very quickly. Second just slow down, using less gas makes less heat. Third pull over and stop and remove lower Grill Cover and replace  when you aren't climbing anymore.  :) One way to minimize potential over heating problem is to use EV anytime a long climb levels out for a short distance.  This gives time for the ICE to cool off and also turn the heater on which does a very quick job of cooling the ICE off. :)

my last tank was during the cold snap here in NOVA  43 and change.  ugh.  With out the heat or Ac on  getting high 40's is easy.  but cold weather hurts.  No grill covers....  Not much sitting in traffic for me since my commute is earlier than most.

 

Where in NOVA are you Josh?

Even with cold weather I was able to squeak out 53.6 mpg's last fill up a few days ago.  With warmer temps I'm back up to 57.4mpg/56mpg actual probably. :)

Mark the Grill Covers really work. ICE Block and Oil Pan heaters too. :)

Im in Warrenton.

The first day I drove with my grill covers noticed my ICE turning off about a mile sooner on a 30 degree morning.
I also notice that driving on EV the temp gauge doesn't drop significantly noticeable.

Today I had to go to Herndon for one of my customers and got 50+mpg both ways and wasn't really trying. I did have a few panic stops which are quite frequent around there.

Grill blocks are a two-way winner; independent of ICE operation, they reduce aerodynamic drag in a meaningful way. It's a top item when making hypermiling mods. I applaud Paul's efforts on our behalf to make something for those of us not DIY-inclined.

I applaud him as well. There must have been a fair amount of time put into this plan.
I just need to find a way to overcome my fear of the license plate falling off.
