Damn Paul:

 

I've been doing it for 30yrs/ 1 million mi. and no accidents.

 

So now I'm going to have to subtract 5mpg from all your fuelly stats to see the real numbers you get in your hybrid as you draft all the time!!  What's your average now, like 53 and climbing?  I guess its really more like 48 and climbing for people who don't draft?

Drafting seems to have insane mileage increases on this car. A few months back I had to follow my mother who was driving a shuttle bus for work (One way, drop it off, head back. I was her ride back.). About 2.5 hours all highway. Kept a decent distance but stayed behind and averaged 65-70mph. I remember my trip mileage ended up being around 55mpg. Trip back under same conditions sans drafting I think it was in the 43-45 range. No fancy hypermiling tricks otherwise.

Yes, there is alot less headwind then when you draft.

I know you are only kidding, but practically speaking I only draft on the FWY and I'm doing good to do it half the time. First you have to find a big vehicle going the speed you want to go and then you are lucky if they stay on the Fwy more than an hour so you end up searching again. I don't draft in the rain for obvious reasons. Wind direction/speed is the big factor on fuel economy with drafting. I have gotten 50 mpg going 80 mph driving east from El Paso for 160 mi. with 35mph tail wind, drafting may only get you 1 mpg. Your effective wind speed is only 35-45 mph. Going in reverse going 65 mph with 35 mph head wind your wind drag is 100 mph so drafting may help you by 5-6 mpg.

Yes Paul you know I'm not going to take away your achievements, it just sounded funny so I had to write it 

I know what you mean its hard to find a truck going the right speed, and even if you do they lose speed up hills actually that's when my chance is to pass them at 65mph in CC.

That actually works in my favor with P&G.

A follow up... I'm now down to 4.2KWh on the new battery. 93K miles, 36K of which on this battery.

How did you get the replacement under warranty?

How did you get the replacement under warranty? 

It's all in the beginning of this thread. it was not easy. It sounds like my case was an exception though. I haven't see anyone else manage this.

 

As a follow up. I've given up. I now drive a 2018 Volt and am exceedingly happy with it. Much better battery management (including active liquid cooling). 54 miles range. I don't have to care about the battery. I just drive the 33 miles freeway to work at the limit, charge at work, and don't use a drop of gas through the work week even adding driving around town.

 

My daughter now has the C-Max and often drives it like a hybrid.

 

It's going to take a lot to convince me to buy a Ford again.

Ive owned a 2017 C Max Energi for almost 2 months. It was originally titled to Ford and used by an employee of Ford From June 2017 until January 2018 when it was sold at auction to my dealer in St Paul. (Midway Ford)

 

It sat on their lot from late January 2018 until I bought it on June 1 2018. I bought it with 7000 miles. I get about 4.1 KWH from 100% to 0%  Charge time at 12 Amp using the factory cord is about 4 hours and 25 minutes.

 

My other car is a 2016 Volt so I am experienced with driving PHEVs.

 

Any thoughts on this?

That is a low number of miles to have a HVB capacity loss issue. I have had a similar amount of lost capacity in the HVB after reaching excessive temperatures during one summer. If I had to guess it is likely that your HVB was exposed to overheating. The best way to avoid reaching damaging temperatures is to actively monitor the HVB temp then limit EV driving and charging during hot weather.
