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:Welcome! Crazy how few of us there are in CO so far!
What's your range been like through the winter so far?
Haha that's awesome. I'm so looking forward to that!You know what does have real-life consequences for me? Being able to smoke fools on the I-25 on-ramp.
You can't average consumption like that because it's a ratio. The right way to calculate it is this: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.
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.
Thanks. Yeah, I kept thinking, this is probably not the correct way to calculate this.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.
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.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.
I have the 20" wheels. Stock tires have been fine in the snow (so far). I was worried about the instant torque and how it might cause slippage in the snow, but so far, so good.Interesting! I too would say the farthest I'll be driving is Breck. Our family has a home up Boreas Pass.
Any of you have the 22" wheels out here? I'm struggling to figure out what to put on instead of the summer only tires...
