Okay, so you all know that in my first few days of driving my new 2019 Jaguar I-Pace (mostly around town for city driving), I settled in around 39.0 kWh - 39.5 kWh/100 mi., so theoretically, my I-Pace should be getting approx 210-230 mi. of range on a full 100% charge. So, now as promised, I did a nice long, mostly highway drive today to a customer's house and back. Here are the stats I experienced in my I-Pace today for highway driving (pictures attached):

Vehicle set to: Normal, Comfort Driving Mode, nothing on (no A/C or cooled seats today as we had a cold front come through last night and it's a crisp, "cool" 67 degrees F, lol! ) except I had the radio blasting the entire time. Cruise Control set to 77-78mph but the car kept adjusting the speed based cars in front of me, etc. The Air Suspension was set to Normal ride height (can't verify if it did in fact lower as it's supposed to for higher speeds).

Total Miles Driven: 113.3 mi. (about 105 mi. on the highway)

Total miles left according to the vehicle: 77 mi.

Average Battery Usage: 44.1 kWh/100 mi

So, correct me if I'm wrong, but it seems that with normal driving on the highway in regular weather conditions, I should theoretically get a max range of approx 190 mi., correct? Maybe a bit less if I have the A/C and Seat Cooling on...so likely 180 mi. I would imagine. Does that seem fair to you guys? Thank you.

Thanks that sounds about right for those speeds. In fact it seems to indicate a pretty good aerodynamic performance. On my other BEVs going 77-80 would cause a more significant range hit. If you are ever bored and want to try you should reproduce the same trip around 60-65 mph.

I get 204 miles:

90kWh battery capacity / 44.1kWh consumption x 100miles = 204.1 miles

I would be ok with range in this ballpark.

Yes, I've always said that if I can can consistently get a max range of 180+ mi. in my I-Pace, then I'm good as the most I'll drive in one day is typically about 150-170 mi. I would rather have 20+ mi. to spare when I get home rather than having to find a Fast Charger and stop for 45 min. or longer. :smile2: And, again, that's driving in Comfort mode rather than Eco mode.

FYI - although it's a 90kW battery, the actual usable battery capacity is 84.7kW (so 84.7 / 44.1 = 1.92 x 100 = 192 mi.) ...

I think only about 82kWh of the 90 are available according to testing by Bjorn Nyland (Jaguar says closer to 85kWh), hence the 180-190 mile range.

Okay, so this screen shows slightly different information; even better 43.6 kWh/100mi. efficiency instead of 44.1 kWh/100 mi. Here ya' go...

BTW - anyone know what the 7.0 kWh is indicating? Is that how much of the small accessory battery (for the radio, HVAC, etc.) used? Thank you!

I think the 7kWh might be the regen during your trip.

Here's my stats for Trip A.

Interesting to me is if I take 89.5kwh battery / 41.8kwh consumption * 100 I get 214.11 miles and my dash shows estimated 215 miles of range at 100% charge.

Also, not sure if anyone is interested, and I'm not saying you need to do this, but I got the steps for how to reset your battery. The dealer was instructed to do this for my car because it was the demo car and at full charge my estimated range was showing 195 or less. The engineering team told the tech at my dealer they thought it was showing this low range because they car had been used for test drives. I haven't done the reset myself since the dealer did it last week.

I like being on forums with other people who can do math!

ECO Vs Comfort Mode

So I tried a test today to see what the usage was in each mode on the same stretch of road. Now the stretch I used was only about 8 miles, but I saw a considerable difference between the two with the Eco mode using almost 10 KwH less than the comfort mode. That is huge. Anyone else try this yet?

Speaking of math ....

If you guys do those sorts of experiments don't get all worked up about a difference when you've only done it once, alright???!!! >

Do it three times at least, ok? I think some die-hards on this forum will even be convinced to do 10 replicates. :nerd:

 

[WattAJag]

Totally true!! However, same day, same weather/wind conditions is also still valuable/helpful! Anything that gives you repeat results and minimizes the variables.

 

[McRat]

Best range test is always a loop on an uncrowded freeway with the speed control set. You use map mileage and if possible measure the amount of juice going to it the car at recharging with a smart EVSE.

2 strange items for today's driving experience. I drove about 31 miles around town (all City driving) in Dynamic mode for some spirited driving fun...but this time, I started out after a full charge to 100% last night at only 216 mi. (was typically charging to 230-245 mi. the last few days). So that was weird thing #1. Now, after today's driving around, I'm back at home with 183 mi. left at an 89% charge, BUT weird thing #2 is that it shows I averaged much lower battery usage than ever before...only 34-35 kWh/100mi. Hmmm...any thoughts?

 

[Time2Roll]

Normal. Many other EVs the range displayed is known as the GOM (guess-o-meter) for a reason. I would not expect much consistency.

Okay but what about the battery efficiency down to 34-35 kWh/100 mi.? I was getting like 38-39 kWh/100 mi. City and 44 kWh/100mi. for highway driving. Interesting that my battery usage/efficiency also changed quite a bit...not sure what to make of that unless it's just a factor of the decreased total max range at first start?

 

[Time2Roll]

Amazing how aware we become of our energy usage and the related fluctuations in an electric vehicle.
I still call normal. Just drive.

I mean unless you make the exact same drive every day in the same wind and temperature and traffic and a hundred other conditions the usage is just not going to be the same.
Some days will surprise to upside and others to the down. in a few months you will find a normal baseline and better relate to the fluctuating data.

 

[McRat]

Wow! I got put in the doghouse today. It was pouring rain, and I climbed 2400', 50-57°F outside with the heater on, normal mode, headlights, stereo, wipers, gentle driving, no faster than 65 mph, and my range would be about 201 miles according to Guess-o-Meter, but when I do the math for 67 miles using 28% of the charge, that says 239 miles.
I wonder which one is right?
There were several accidents, including a black import sedan on it's roof in the #1 lane of the 241 Toll Road. Many cars when off the road into the median, a couple spun backwards. Few collisions.

In California, we do not know how to drive in the rain. They think hydroplaning is an Extreme Sport on ESPN, and water improves your braking distance.
