As someone who drove an original fiat 500e with a similar range, I can assure you this is not enough battery for anywhere but the market it’s designed for (South Korea). You will eat through that “best estimate” of 120 miles in a day’s worth of driving, especially with additional passengers and the AC running.
The average US daily drive is less than 40 miles. Accounting for outliers and a margin, let's conservatively say 60 miles. That's still probably more than most average commutes.
That's half the best case rated mileage, which is for sure more than the "realistic" mileage with a full vehicle and A/C running. There's no way that would reduce it by half, even from the best case rating.
You’re going to get 100 miles of real world range out of that 120 rating. Then you will lose 20 for running the AC. That’s 80 miles. If you add passengers, that’s another 20 you will lose. You’re now down to 60 miles of range. Better hope your commute is under 30 miles each way and that you don’t have to stop for groceries or something on the way home. Also that last 20 miles of battery power, the car is going to go into power saving mode and will turn off the AC.
Losing range has way more to do with speed than AC or an extra passenger. Taking side roads going 40 mph will give me a massive range boost vs the highway going 70-75 mph (2011 Leaf with "82 miles" range on the fully charged GOM).
I barely notice a difference with extra passengers and weight (which makes sense since an extra passenger adds about 0.5% to the cars weight.
And running heat kills battery much more than AC. AC will impact it a bit, but usually only about 5% in my estimation
Can confirm, I had a '11 Leaf SV in the boiling desert heat. I could get 85 miles out of it when the gom started at 70 (I think the highest I saw was 5.4mi/kW) but if you - hypothetically cough cough - ran it flat out at the 93mph top speed, it could eat through that 70ish gom in about 15 miles. Speeds above ~50 absolutely tank the Leaf's range.
Heat is bad unless your model has a heat pump. Late 1st gens had it (as an option, I think). I've heard it's more than worth the upgrade. But heat on the battery is way worse, as it kills cells fast. I lost 10% SoH (I think that's the correct term, been a while) in 4 months in the desert heat. Environment is the biggest factor by a massive margin for the Leaf. Range is short term pain but battery degradation is permanent and can only be solved with replacement. It's the one thing I didn't like about the Leaf - everything else is great.
1500 kg car and one 75 kg passenger makes 5%, with 3 passengers 15%.
I stand corrected. I still don't think it affects range much
Do they officially call it a guessometer?
I don't think so. That's just we all call it
