Over Vail Pass

[twistedskipper]

Planning an EV trip from the Colorado Front Range over Vail Pass on I-70 to Carbondale CO and back.

Looking forward to seeing how the climb and descent consumption rates match up to ABRP's predictions.

ABRP says we can get all the way there with no charging stops, arriving at our destination with 22% charge remaining (starting at 100%/310 miles) after driving 222 miles in a Tesla Model 3 LR AWD.

ABRP says we can get all the way home (starting at 22%/68 miles) with only two 15-minute Supercharger stops, so only 30 minutes of charging for a total of 425 miles mountain driving there and back, arriving home with 15%/46 miles remaining.

My son reported driving up to Mount Evans and back from Denver and regaining almost all his original range coming down (also Tesla M3 LR AWD), so the ABRP predictions do seem reasonable. 

Has anybody else here driven any EV across Colorado on I-70 and can report their consumption results across the Continental Divide, especially Vail Pass?

I did the drive across Colorado from Las Vegas.  I only looked at the usage from the Eisenhower Tunnel back to home in Arvada (Wadsworth Exit)  I used 2% of the power on the way back, a distance of approximately 54 miles. 2015 MS 85D  Hope that helps.

I don’t have many specifics, but we drove 2 adults, 2 kids, luggage and 2 smallish dogs round trip from Denver to Moab. ABRP and Tesla nav were pretty close, like rounding error. Model 3 mid range RWD 18 Aeros. Hammering uphill you might see 500-600 wh/mi. I think our consumption between Glenwood and Minturn was in the mid 200 wh/mi going the speed limit.

Listen to Uncle Bjorn and just hammer it.

I don't have the details any longer, but going from UT through Glenwood Springs and on to Limon CO, as part of our annual NY-CA-NY winter drive this year, there were uphill, cold weather stretches of very high wh/mi, but the long downhill out of the mountains used about 3% of charge for probably 75+ miles.  There were wide swings in "estimated charge on arrival,"  with some uncomfortable negative numbers, but in the end it was dead-on accurate.
