Initial highway range ...my estimates

Hi, I am a relatively new I Pace owner, and really enjoy the car. I don't have a daily need to use the full range of the car, but mostly take short trips of less than 10 miles. The GOM has ranged from 282 to 201 when fully charged. I understand there are future software updates that might improve this estimate. However, for my needs I really only need to know how far I can go on a single charge, driving on a highway, not a combined estimate of all my driving . What I think would help in the future is if the GOM is presented both a highway estimate and a city estimate.

So, I analyzed the past three months of driving, and only at trips > 10 miles. My car is an HSE, 22" wheels, Comfort mode, and typically 2 passengers. I also live in Florida and the temp is around 90F on my highway trips. What I found is that the avg energy consumption on these highway trips would give me an average range of 237 miles. In the "winter" months I am guessing this might improve another 10-20 miles in range. So this is quite satisfying to know, even with using the larger tires and high temps.

I have attached my data in case you want to see the details.

I too am in the Orlando area and I have not seen another I-Pace in the wild since I got mine in December. Good to see your posting. I drive mine on the freeway at about 80mph and am not sure I would get 237 miles. It seems to be closer to 200 miles. Right now the ACC is constantly at work with the big front window letting so much heat in. I definitely had better mileage in the cooler winter months. Glad to hear you are enjoying the car. Have you tried a long trip yet where you needed to seek out high speed charging stations?

I have not planned a long trip yet where I would need to charge, although I am considering a trip to NC. This would be 520+ miles, which would be two charges needed, and even if I found DC fast chargers along the way (ie Savannah), the total time would be 10+ hours. I can find a fight for less than $80 and it takes 1.5 hrs. I am not so keen to take long driving trips as it is.

Traveling to Tampa/Clearwater I will do several times a year, and this should easily do in a round trip without charging. I don't have a need to go to Miami, but that might not work in summer temps, as this is 240+ miles.

BTW - I am getting the H228 update next week at the dealership along with two other dealer flagged updates (some charger sticker needed and I believe a change on the rear latch).

It gets 190-210mi. for max range for ALL HWY driving (Comfort mode, A/C on, seat ventilation on, cruise control mostly on) & 220-240 mi. max range City...that's been my experience driving mostly hwy miles since 12/1/18.

You are being very optimistic to say you could travel 520+ miles in 10 hours with 2 charging stops

Sounds about right for highway driving and no traffic.

2 charging stops to add about 150 miles via fast charger are likely going to take 30 to 40 minutes each depending upon 50Kw vs the slightly under 100Kw. I think you are looking at 11 to 12 hours.

@bremington , be aware that the consumption estimates provided by the car are consistently optimistic due to a calculation error in the car's software. Do not trust the reported miles/kWh. Go with the SoC; measure the distance you've driven and take the SoC reading difference (between start and end of drive), in the linear range, which is between about 20% and 90% SoC. You will see that you use a lot more energy than what the car reports in miles/kWh.

Be prepared for three charging stops on a 520 mile trip. And yes, on a 50kW charger plan for 1 hour per stop.

I live in coastal North Carolina which is particularly flat. I have rarely taken my I-Pace out of town and it is excellent for my needs. This past weekend I had occasion to drive exactly 200 miles inland, the first 165 miles on (mostly) flat I-40 with the remainder on a good state highway (60mph). Temp was 85 & humid. Only one person in the car. No luggage. One outbound trip I stayed consistently 78-80mph and had 10 miles of range remaining. On return, I stayed at 70mph on the interstate and had 38 miles of range at the end of the trip. From other trips, the range appears to drop precipitously if you travel 80+mph. The 235 mile range seems attainable at the speed limit without much luggage or any passengers.

@sciencegeek : I am still on the 18D/14.1 software but if I don't vary my driving style I am finding the GOM to be slightly pessimistic to what I can really do. So I am curious what the difference is. It seems to pretty much pad the range by around 10-20 miles specially on longer drives (60 miles+).
