Extended Range 320 Miles???

[jeff_h]

Other Lightning owners, how many miles does your truck show on a 100% charge and do you have the standard or extended range battery?

Hello neighbor, I'm right down the road in Hampshire County. If you're in Falling Waters you probably spend plenty of time on I-81, and if you drive balls to the wall your efficiency will take a hit and the range estimate (that many call the guess-o-meter) will go lower... it's basically a calculation of the last couple (or so) driving and charging sessions and tells you "keep that behavior up and you'll get about X miles."

On my 2023 XLT ER, the handful of times I've been at 100% charge it's been as low as around 280 and as high as 360, so the driving behavior and climate will play roles in the estimated range.

Just to make you feel bad
This was last week when it was about 75° for the high my miles per kilowatt hour were between 2.5 and 3. Cool front came through low 60’s high and today it was closer to 2.0.
If you go to your settings on your touchscreen and put it on this trip, it will tell you where your energy is being used. I.e. climate, driving, exterior temperature and/or accessories.

OP complained about what the truck displayed. The display and what you actually get can be very different.

The truck does some calculations including variables such as Temperature. I don't know if it also "learned" your mi/kWh and takes that into account (do you have lead foot and travel at 85 mph?) My observation is that I got over 320 displayed in summer but the other day I accidentally charged to 100% and it showed only 316. 80% used to show 246 mile range but with cold weather it can be as low as 216.

I find that if I prepare the truck for departure ahead of time it can boost the distance estimate significantly on a cold day and it will also claim to be getting better mileage on the road.

When I look at my Trip 1 / Trip 2 mileage I can have very different numbers form the "This Trip" reading, which is usually much lower. The range and usage estimates swing wildly. On a cold day I might drop 2 estimated miles for every mile actually traveled, then suddenly I travel 10 miles and only drop 1 mile on the display.

So, I simply make sure that I have an 80% charge for my usual 60 mile round trip and 90-95% for my 120 mile round trip. Usually I get home with 40-60% charge indicated. I'm in "relatively flat" central Maryland.

Finally, I am not sure, but I think EPA is based on 55 mph. I took a leaf peeping trip and after several hours driving still came home with a very high charge remaining... sadly I did not record the numbers but I think it went from 100% to 75% in 6 hours that include some stops and lots of 30-45 mph back road driving.

Couple of people here are being sarcastic, there's nothing wrong with your truck. You are missing the point, I think, that we are trying to convey. Do...not....trust....the range estimate. Watch your efficiency as you drive and learn/adapt your driving habits to take advantage of an EV to maximize the efficiency for your use case. On the highway, in good weather, expect around 26 miles per 10% of charge at 70mph (roughly 2.0mpk). When in the city (or under 60mph) expect around 33 miles per 10%.

The bottom line here is that the range estimate shown is based on recent driving history. Like Taxmanhog mentioned, city driving for 2 months will get it to show 320ish miles of range at 100% charge. But if you know you are going to be driving on the highway and only getting 2.0mpk, you have to make that range adjustment yourself. There is no way for the truck to predict your future driving conditions. The opposite is often talked about here. Where the truck doesn't think you have enough range. If you know you are about to drive down hill for a while, you can expect longer range from the regen.

When I come down from the nearby mountain, I actually gain around 8% charge. We can't expect the range estimate to know that's going to happen. So don't worry about it. Learn your driving conditions and what efficiency that results in. Watch you state of charge and efficiency, that will always put you in a good place.

Thread moved to Charging node, for the benefit of all regions starting to feel the cold weather effects of charging and the seasonally depreciated expectations of the guess-O-meter.

Not complaining here. Went with a BEV with full knowledge that I would lose up to 30-40% range when the cold weather started to set in. When I took delivery of mine in Sept, it was 100% SoC and showing about 500km (310mi) of range. These days it's showing closer to 400km (248mi) at 95% SoC and I expect it to drop more as the weather gets colder and the battery gets cold soaked.

Doesn't bother me much and I'll just charge more often if needed. Even most of my longest commutes is less than 250km and there's usually a supercharger nearby. Like past posts, the range display is a guess like your phone percentage.

Here is a snapshot from 2/29/2024 when I was preparing my Lightning Lariat-ER for a cold weather road trip. This involved charging to 95%, then preconditioning the battery pack for long distance journey and topping the battery to 100% in the final hour before rolling down I95

Still rubbing that trip to New Jersey in our collective faces? We get it. You're a movie star.

Sheesh.

Apparently the OP isn’t alone with his GOM questions:

 

[Zaptor]

Yeah, my Ram didn’t get 15/22 either.

Only vehicle I've ever included the "tenths" in when I told people what I was getting with the HEMI... "Not just 11, that would be terrible, it's 11.6 miles per gallon". Don't miss that fuel bill.
Cheers

The result from 105 miles of driving in the last two weeks, ~50% of it at 60 to 65 mph. As @TaxmanHog suggested, you don't have to charge to 100% to get the GOM mileage. 157 mi/46% = 341 miles on a "full tank."

As others have pointed out, it's the terrain, the temperature, and how you drive. I always gently accelerate, drive in 2PD mode with the standard drive settings, and strive for 100% regenerative braking. If you enjoy the power of the vehicle, letting it out and leaving others amazed, you ain't gonna get the 320-mile EPA rating. If I only do street driving, I get my GOM as high as 375 miles on a full charge (~2.9 kWh/mi). It's been 70° to 85° F here most of the last few weeks so that probably helps a bunch.

If you want to monitor how you're doing, set your dash to the My Trip view and pick This Trip for the view you want displayed. It will show you the computed kWh/mi for the trip in progress, and you can watch the rating go up or down depending on the various driving parameters, your acceleration, braking, etc. You can see if there's anything to improve about your driving style, preconditioning, etc., that way.

Simple answer that it is achieved using the EPA testing protocol.

You achieve it when you drive in mixed driving and realize 2.44 mi/kWh of consumption. It's not easy, almost impossible to do driving at high speeds. Pay attention to consumption, not the GOM.

If you don't need to regularly drive more than ~250 miles between charging opportunities, what is the concern? If you need to drive more than that without charging, it's probably the wrong truck for you.

I don't find it hard to get the rated range when driving with all-season tires, at 64MPH or less, in nice weather. But I also don't often choose to...

thank you, I appreciate your explanation

I created this little matrix to show the ESTIMATED effect of temperature and effect of avg speed on range. I hope it helps. As Zprime stated... if you need to get a certain mileage on a trip. Monitor your MPK (131 kWh battery so, ever 10% you use is 13.1 kwh) as you go and do the math to figure out if you will get there or need to slow down to maximize efficiency. I'll go as far as resetting one of trip monitors once I get on the highway so my MPK is not polluted by any city driving that was done to get to the predominate interstate or highway.

It's helpful to periodically reset your driving history too so that the estimate can re-learn your habits & get closer to accurate. After the reset it should be very close to 320 until you start driving.

I do it as the weather changes so I don't have summer kwph data in my winter results (and vice versa).

That's called a Jedi Mind Trick.

You can reset the data all you want. You're wasting time and effort. It will always be wrong. It used to be spot on accurate in the beginning, but it was changed to kowtow to the people that complained.
