Denver Area I-Pace Owners

Well, since others have started threads for their areas, let's do one for the Denver Metro Area!

This is a thread to facilitate meetups and introductions of those of us living in the Denver area.

I live in the Sloan's Lake neighborhood!

Not in Denver, but reasonably close in Colorado Springs. Had my corris grey FE since November. Love the car.

Welcome! Crazy how few of us there are in CO so far!

What's your range been like through the winter so far?

Good idea on this discussion. I am north of the Denver area.

Looking good!

I'm loving my car so far.

Still curious to hear range you all are getting in our area.

According to the nav computer, I've been averaging around 45 kwh/100mi, or around 180-200 miles total range. Of course, I've never really taken it down to near zero to actually check to really see if the computer is accurate on that. The one experiment I have run is the following:

Full charge from my house in Colo Spgs to my place in Breck. 107 miles, net elevation gain of 4000 feet, arrived with 42% of battery left.
Full charge in Breck for the return home, arrived in Colo Spgs with 65% left.
Normal winter weather, roads relatively dry. Set to comfort mode. Averaged maybe 55 mph, with stretches of 75 mph. (There are some small town speed traps along Hwy 9...)

The math would imply an average range of 245 miles for this up-and-back (184 uphill, 310 downhill). So maybe the on-board computer is overly conservative.

All that said, that Breck trip is as far as I plan to take the car and I almost never drive more than 50 miles in a work day. So, while the efficiency is somewhat disappointing, it has no real-life consequences for me other than a marginally higher cost of electricity.

You know what does have real-life consequences for me? Being able to smoke fools on the I-25 on-ramp.

Haha that's awesome. I'm so looking forward to that!

You can't average consumption like that because it's a ratio. The right way to calculate it is this:
Used 58% plus 35% = 93% on 2x107=214 miles. So 214miles/0.93=230 miles on the hypothetical 100% charge.
Not bad, probably partly due to your thin air.

Thanks. Yeah, I kept thinking, this is probably not the correct way to calculate this.

I posited the question about BEV performance in higher altitudes a few months back, but couldn't find any studies regarding this. My assumption was, since the efficiency in these vehicles is dependent much more on wind resistance than ICE vehicles (which are way more dependent on the efficiency at which fuel is converted into motion), then higher altitude/thinner air should result in substantially increased efficiency/range. But, like I said, I couldn't find anything proving this theory.

Also, none of this explains the difference between real-life efficiency and what the on board computer is predicting.

Air density at 7000 feet is about 80% of sea level.
Drag is linear with air density (quadratic with speed).
So the average drag on your trip was about 80% of drag at sea level. That makes a difference!
Remember that the prediction by the on board computer is naturally subject to high variance.

Also, just to point this out, my trip from Colo Spgs (6K ASL) to Breckenridge (10K ASL), starts out with an immediate climb to about 9,000 within the first 15 miles. After that, all of the trip takes place above 8,500 (and tops out at 11,500). So, air density for this trip is even lower than 80% of sea level.
