They should post cold weather mileage and hot weather mileage

[Billyk24]

Let’s just build more fast chargers then this will all be moot

True. However fast chargers being installed in Michigan including the UP via government grants are no faster than 62.5 kW ratings.

I’ll take that over L2 chargers

But my mileage wasn't drastically different. It all depends on where you live. Should they customize it for every person on earth?

no they need to post mileage at 90 degrees 75 degrees and 32 degrees its called transparency

What about range at 75 MPH, 55 MPH, 40 MPH and 25 MPH? That would be helpful. What about range with all the different tires you can put on the car, and different tire pressures? What about range with four people, 2 people and one person in the car? What about range with a bike rack mounted on the back at 75 MPH, 55 MPH and 25 MPH? Oh, and a roof rack.

So many factors impact range, and temperature is only one of them.

And what is range? 100% to 0%? Who really is willing to drive to 0%? And what about the fact that most people charge to 80% on trips? Should they also provide the various range estimates for 80% to 10%?

In all seriousness, I think a highway range with a standard, consistent high speed would be very helpful. To me that is the biggest misconception, because most people think an EPA range of 270 miles is how far you can drive on the interstate. It is not.

I vote "no" on cold temperature ranges, and "yes" on a standard highway speed range estimate. Maybe the car manufacturers will come up with one. Or we can just use C&D 70 mph test as a guideline.

Or we can just give people relevant and accurate information up front?

I actually think the OP’s idea is a good one.

Your comment assumes everyone is tech savvy and smart enough to understand what it they’re researching.

You shouldn’t need an advanced degree to buy a car.

Many people (and I’m thinking of my parents and all their friends) read a range estimate for a BEV and would logically and incorrectly assume that’s how far you can drive it. Especially coming from an ICE they’d also assume that it’s highway range.

More accurate and detailed info on the window sticker and in advertising would go a long way to educate ICE drivers on how a BEV works.

Ironically, the most common question I get about my car: “What’s the range?”

My answer is 260, but then a ton of disclaimers.

My issue with this idea is that there is not a single mass produced vehicle on the market that gives this type of granular data on mileage. There are way too many variables in play to ever give these numbers with any sort of accuracy. What is the mpg of a Corvette C8 in 85° weather with the AC blasting, doing 78 mph? Everyone understands that epa mpg numbers are nowhere near real world, but we all expect EV’s to be bang on the number regardless of conditions. I can’t imagine someone could go to the search engine of their choice and search for “[ev name] range” and not find out within 2 articles that cold weather range is significantly less than warm weather range. I know I couldn’t.

Another thing to remember, the MME in 70° Weather is around 3¢/mile* to drive. Even if you lose 50% of your range to cold, that still makes it around 6¢/mile, which is still less than the 13.6¢/mile for gas cars getting 27 mpg with gas at $3.679/Gallon.**


*assumes charging at home at 12¢/kWh
** todays local price for 87 octane and a car with an epa rating of 30-32 mpg.

Show me one single ICE vehicle that advertises this way.

They don’t need to. ICE doesn’t lose half its range in the cold.

They lose half their range in the city. Which is why they post city and hwy mpg.

It’s a pretty straightforward argument: if something cuts your range in half, they should test and disclose it.

 

[JoeDimwit]

I remember a year ago, when I was still driving my Escape, running the air conditioner significantly impacted my mileage by like 20-30%. That was never disclosed. ?‍

No it doesn’t.

Oh, and the EPA tests include cold temps and a/c ON.

“Things changed in 2008 with the implementation of three new Supplemental Federal Test Procedure (SFTP) tests by the EPA. The SFTP included faster driving speeds, harder acceleration, colder temperatures, and additional use of air conditioning.”

No it doesn’t.

yes.. it does. I saw my mpg drop from 29 to 23 when I ran my AC. With my own eyes. Computed on my own calculator with miles driven and gallons pumped in to get back to full.

oh yeah, I also NEVER got the EPA rated mpg. Not once.

 

[Gullwingdmc]

Iv owned a e car before, and no one tells you that the battery mileage will be drastically different, depending on the weather conditions. I wish there were 3 battery mileage posted one at 32 degrees another at 75 degrees and finally at 90 degrees

I think this would be a good idea. Sort of like city/highway MPG. Have a Summer/Winter range.

I don’t see why what we do for ICE vehicles is relevant at all to this conversation.

I’m guessing you drove the exact same route and speed when you calculated it too?

I’ll stick with the documented instrumented tests like in the articles I linked instead. 3% is the difference they calculated.

If you actually lost 20-30% in fuel economy turning on the a/c, your car is broken.

Just be happy you don't have an ice car....oil prices will hit the roof in a few days with WW3 breaking out in Europe...all this back and forth about summer and winter mileage for a BEV will seem ridiculous and inconsequential...when gas hits 10 dollars a gallon....

Don’t get me wrong, I am.

This is just something that car manufacturers should be up front with to help people understand the transition to EVs. I knew it was coming, but a lot of people didn’t. I actually got significantly above the EPA range in the summer, so that was great.
