Can the Energi get you more regen in hilly terrain?

I currently drive a 2013 SEL hybrid. I like it a lot. I have been worrying lately about the transmission possibly breaking at this point in the car's life. It has 116k miles. 

 

If/when the day comes that I need to replace the car, I'm giving thought to the energi model. Because of the transmission issue that 13's had, I would only consider 2016 and up. The price for the energi is roughly the same as the hybrid. When buying the hybrid the first time, I sought it out because I figured the battery hump was unacceptable. 

 

I live in a hilly area. Often times when driving, it regens to full and then it cannot regen more. Also, I end up using the ICE engine a lot on some inclines when I'd rather use the EV engine. 

 

Will the presence of a larger capacity battery in the Energi model result in more regen and recapture? 

 

And speaking of which, is it possible that age and inevitable capacity loss of the 1.4 kwh in the hybrid has resulted in the car not capturing as much energy from regen? Would a more recent model CMax get more regen on hilly terrain?

The HVB definitely loses some capacity and a new would be able to regen more.  :(  When mine was new I didn't fill up the HVB as often. This has very little effect on MPG's.

Yes the Energi battery is much larger and when empty will absorb many miles of downhill coasting.  If it's full (or nearly so), it won't absorb much, if any.  Full is full.  If you live at the top of a hill, it would best not to charge to full so you could get "free" miles when you leave.

So theoretically, it can go from zero to full 20 miles on Regen?

On a long, multi-mile decline you can increase a significant amount of battery state of charge with regen.   Most of us do not have a multi-mile downhill on our daily drive.  You switch between auto (use on the downhill and for slower driving) and EV later (uphills and faster speeds) to "play around" with the battery state of charge.

Definitely get and Energi, it gives you ALOT more options than the hybrid.

Driven through the Colorado mountains 2 years in a row. Just used hill descent control which only maintains cruise control speed and doesn't use FULL regen. Stupid easy in that environment to get a full charge from empty.

Driving back and forth to my son's college in Vermont, I've never had trouble recharging the entire HVB on the downhills.  I generally arrive with a full charge, since the college is in a valley...

The only downside is using ICE on the way up.  I always worry about using the battery uphill and heat issues.

Stolenmoment,

 

Where is that college, you mean Norwich?  I went there in the 80's   :thumbsup:

Do you have a ODBII gauge like ScanGaugeII you can monitor the HVB temps and not worry about it. :smile2:
