Why is my range so bad?

[ChasingCoral]

Watch the Munro videos where PROFESSIONALS, unlike yourself, have torn down every single component of the Mach-E, and compared it against the other big market players (Tesla, ID.4, GM, etc.)

Yes, they look at all the components but did they test them? Sandy is a notorious Teslastan, stockholder, and paid consultant. He’ll spew the usual Tesla story line and rarely admit they never reach their range estimates.

EPA-rating aside, said heat pump is still more energy efficient than the MME's PTC heater.

Yes, to some extent, at moderate temperatures. Heat pumps have advantages but are no panacea.

Yeah, that seems way off. I wonder why some cars are so bad at the estimation while others aren't?

A lot of the GOM is based how how you have been driving. It knows nothing about your future driving style or plans.
See

and myriad other threads on the GOM.

Yes of course, but he is also a big fan of the engineering Ford put into the Mach-E. Being an automotive solutions engineer, he sees the characteristics that Ford brought to the table and merely elaborated on simple refinements (some that are his POV, as well as the POV of other automakers) to increase efficiency, reduce weight and decrease manufacturing and assembly costs.

Teardowns in a shop are one thing, actual real tests are quite another. The EPA fallacy has been exposed by several reputable sources - alex on autos and edmonds ran a model Y and Mach E on the same course at the same time. There have also been tests by insideevs (definitely pro tesla) as well as several long road tests in europe that had the same findings.

The end result is that Teslas do not reach their rated EPA in real world conditions and speeds, and the Mach E typically meets or exceeds its range - to the point that the Model Y and Mach E have comparable range. The Mach E has a bigger battery than the Model Y, but the aerodynamics and slightly lower weight of the Y make up for much of that discrepancy.

How often are you launching the pony express, or trying to impress with speed, or what ever else you want to call slamming the go pedal to the floor?

A lot of people new to EVs are so impressed with the power at any speed they play with it and then find their battery range is gone in short order.

The GOM (Guess O Meter) shows range based on your driving history. The more you play the less you will have on that meter. Behave for a while and it will gain range.

Cold weather and rain both reduce range but not more than 15%-20% in my experience over 2 winters.

The range I've been getting shown for the past week. I've not changed my driving habits, I drive very grandpawish and last month even received 60% perfect driving! lol My commute from home to work I get anywhere between 6kWh to 8kWh. About 10 miles of freeway at 75 and then about 7 miles of 30mph or lower speeds. Also have a down hill from a bridge that might build some regen.

Its been in the low 70's here, around 55-65ish in the early mornings. I park in a garage so the temp should not be going down too awfully bad. I typically show about 265 at 80% SoC, so its a pretty big displayed drop. Really kind of interesting to see such a big drop for temps that really aren't that cold.

I will mention I've not been conditioning my car. Kids are out of state currently so my wake up time for work is kind of whenever I feel like it lol Where when kids are home I take them to school at the same time every day.

My CA RT1 (RWD ext range) has lost more than 50% per GOM. In the 90s with the AC set to 65, the GOM was around 330 for full and mi/KWh was typically between 3.6 and 4.2. In the 50s with heat set to 68, the GOM is around 200 for full and mi/KWh is typically between 2.1 and 2.5

My only thought is that a lot of my trips are short, so the cabin heat never stabilizes and the whole trip is spent with the e heat coils on getting to temperature.

Dropping from 3.6 to 2.1 is a 42% drop. 4.2 to 2.5 is a 40% drop. Of course those aren't accurate numbers - first you don't know if 3.6 was about to trip to 3.7, or 3.5. In addition, many have noticed jumps, like it showing 2.8 then 3.0, but never 2.9.

Regardless, you're getting a 40% loss due to running the heat, and you can validate that by not running the head and seeing, yet operating in the same temps.

I have the same issue - 1st Edition - Europe with an announced range of 600km. I got it in May and since, never got more than 470km when fully charged. Ok by reading your comments GOP/Ford is super conservative, but here we're talking about ca 25% less than what was announced.
How not to rely on the GOP when planning a long-distance trip? And let me add that I'm not driving aggressively rather the contrary as I'm trying to beef up the GOP when fully charged - but no success so far...

 

[RickMachE]

How not to rely on the GOP when planning a long-distance trip?

Easy. Look at your miles per kwh on your recent trips, assuming some of that is highway, and drop it a few tenths. If you're getting 2.9, plan your trip with 2.6. If you're getting 2.6, plan it with 2.3. Make sure your first stop has an earlier alternate. By then you'll know.

What got me was he praised the Mach-e in his first video than there was a video with insideev where they sat him down and made him be a good little employee. It was so obvious you could see him struggle. Thinking all Ev's are good Ev's at this stage.

Watching my consumption go from 18 KWh/100 Km (3.47 mi/kw) this summer to lately 28 KWh/100 Km (2.23 mi/kw) the difference between 68 and 5 oF it appears. Throw a good head wind in there and range is still king up here. 91 KWh and no 80% cliff would be nice before winter as Ford has mentioned may be possible? ?‍

Big news anyway if it comes. Definitely crosses off two on my short list for the mustang. Starts to look a bit more like a 100 KWh pack not 77/78 like others (88 * 0.8 = 70 KWh right now). Working well here and noted a short list. Only gas I have put in it in 9 months has been a couple of jerry cans in the back. Wish I had this when I was billing mileage .

I'm doing a sloooooooooow 110ac charge, and it says 100% is 241 miles I wonder if the last time it was in the shop the techs loaded wrong firmware.

Call me confused. 241 miles and you're questioning it? Portland's in the 50s, and 40s overnight, right?

Exact same vehicle, I'm showing 195 miles at 90%. That's 217 at 100%. You might want to read the entire thread, unless you're wondering why it's so high?

 

[RickMachE]

In a further example of how the GOM changes without driving, solely due to temperature, on Thursday morning FordPass showed 195 miles of range. The car hasn't moved, nor has it been unplugged. Charger is powered except 11AM - 7PM M-F. As of this morning (coldest night so far), it is showing 187 miles. That's a 4.1% drop (ignoring rounding) as it sat still in the garage.
