A very cool range estimator

[Derek]

I've been playing with this really slick range estimator tool with all three tire options.

Yiikes - With some additional weight and a head wind that range drops significantly. 122mi range with 300lb in the bed and 10mph head wind. I like to travel at 90mph on the highway - lol.

That calculator most definitely does not correctly account for ambient temperature. If you switch it from 70F to 30F you only lose 10 miles of range, when in reality you're going to lose at least 15%. At the same time jumping just from 65 to 70 loses you 20 miles of range?

It's a cool little simulation but it's missing too much information on the Rivian's systems to be accurate.

With what I inputted, if I was towing a trailer, I'd get less than a 100 mi of range. lol. Something seems amiss.

Just play with abrp...

Give me my R1T and I’ll post the range with different speeds and loads.

BRING IT

Don’t lose anything like 15% in a Tesla. What makes you think you would lose that much in a Rivian?

I agree, 15% losses at 30F is likely way off. My Tesla Model 3 loses 25% at 30F. I would expect Rivian to lose a similar amount.

Yikes, if I head through Texas on a cold winter's night at their 85MPH speed limit, I'm only going to get 147 miles in range!!

I wouldn't, the Rivian is using a lower percentage of overall energy expenditure to heat the cabin.

I was just having this thought earlier. I think that cold-weather range-penalty is going end up higher proportional to how efficient your vehicle is. The overall energy to heat the pack & cabin will end up using roughly the same watts, so you lose less energy (percent-wise) out of a larger pack.

If it's true, it's kind of a weird irony that more efficient vehicles are more penalized in bad weather.

One of the owners has mentioned they are seeing about a 15% hit.

And no, I can't remember who it was or where they said it. Lol..

Curious where you got this chart from.

My Model S has very little range impact from 45 to 90 degrees based on my experience with it.

It is the data from my car.

Data logging and analysis by teslafi.com

The website/app takes your Tesla username/password and pretends to be the official Tesla app, sucking up any and all information Tesla would normally send to the app. Unlike the official Tesla app though, it saves the data forever.

Interesting, I have not been logging the data but basing this off of deciding if I have a high enough SOC before I leave.

I’ve been driving from the coast to Coachella Valley once or twice a month for several years in the car and range is pretty consistent all year long. It is the same route all year in different temperatures door to door. I am not seeing a 20% difference on the 90 degree days compared to the 45 or 50 degrees that you see.

Most of my driving is in Southern California and I’ve not driven in temperatures below 20 in this car but I personally do not see any significant difference in my Model S until I get below 35.
