What's your average Miles/Kwh?

[mikeriv]

Hi all, new here. I have an order for an R1S, and have been curious what current owners are getting in terms of "fuel economy".
I know the R1S is rated for 321 miles on a full charge, but as with any vehicle, I'm sure that can vary from real world use.
So what's your avg? How do you drive? (aggressive, hyper-miler, etc)
Thanks!

I have a R1T and just got back from a 835 mile weekend. Did 75% on interstate going about 75ish and 25% on small highways. I did a couple launches for my wife's family but otherwise drove pretty normal. For me that is pretty conservative. I averaged 2.35 over the whole distance. I am not sure how that compares to the R1S's out there but it is some reference. I have 21 inch tires as that makes some difference too. I drove in conserve most of the time and my average comes out about 20 miles less than the stated starting range over a whole charge if my math is right.

Here are two of mine. Both are a mix of freeway and city.
R1S 21" Road tires, 49PSI cold pressure. Feather foor driving.
#1 Lynnwood to Auburn,WA
#2 Auburn to Ashford WA

Going down hill the last 15 minute gauge maxes out at 4 miles per kW. I can see that frequently on I10 East dropping down into the Coachella Vally.

Using my trip meters on longer trips the R1S with 22s I usually average in the 2.2 range doing 65 to 70.

Shorter stuff around town lot of 10 to 20 mile trips, seems like the battery does not really warm up and tend to be in the 1.8-1.9 range

Here is an example of miles I drove around SoCal including a lot of day to day driving.

LOL. I can show you 4.01 on that chart and .86 on that chart.

Weedwacker AC sucks down the juice for short trips. Worse than cold weather in 2023.22

My lifetime is 2mi/kWh and everyone’s truck on RF is more efficient than mine.

21s

I’ll second (triple?) the note about short trips being worse efficiency. Typically <2m/kWh.

I just did a 120 mile trip yesterday. I have R1T, 21s, all purpose mode, drove 65-70 most of the time, ~85 degrees, very little wind, got 2.4. Overall pleased with that as its ~300 miles of range (127 kwh usable battery, I believe) and I didn’t even use conserve.

Guessing R1S would be similar. ?‍

1.3 to 1.7. I like to make money and drive fast cars.

Just did a 1300 mile road trip. Was consistently getting over 2.5 mi/kWh, with my best at 3.2 mi/kWh! Overall not bad...EA does need to work on their chargers, at least one was down at every stop. Several were severely throttled.

I have a R1T quad motor, 21" AT tires, running in conserve mode for the trip.

I love that you guys can go hundreds of miles driving 65-70 mph. I'm dealing with a posted speed limit of 75 and most traffic doing 85 +/-.

Here are the figures on my R1T from new. The mileage shown is the entire mileage of the truck. She about a thousand miles of highway driving coming home from the factory. The rest is all local driving.

Yes it can be a struggle but I find that driver+ has more constraint than my leaded right boot.

In reality though on my really long stretch including I10 across Texas where I pretty much stayed around 75 even in the western portions where speed limits are 80, that driving a little slower is actually faster on long trips as the charge stops do not take as long. On a 200 mile stretch the difference between 70 mph and 75 mph is 12 minutes. 80 mph the difference is 21 minutes.

If I get 2.3 miles per kW at 70 I use 87 kW. If I get 1.9 at 80 I use 105 kW, if we assume that most of the extra 17 kW I need to replace is at 150 kWh then Out of the 21 minutes I saved I use 7 minutes charging.

That 105 kW is 82% of the 128 kW usable, so I need to charge to at least 90% to make it with 8% left. The 87 kW is only 67% of the battery so I’m probably good only charging to 75% for that stretch. The difference of charging from 75% to 90% at an average of 40kWh 13 minutes so I use 13 minutes at the top and 7 for the additional kW or 20 minutes of charging to save 21 minutes of driving.

Now if the stretch is 240 miles, I do not make it at 80 mph, need to find a place to charge between the 2 chargers.

For me, 120 mile trip, don’t need to charge 80-85 it is, driving cross country driver+ at 70 is my friend.

As a side note, this past February, I10 west in Western Texas, 80 mph into a medium headwind I was under 1.5 miles per kW, slowed down to 73 and got closer to 1.9 miles per kW.

... If I get 2.3 miles per kW at 70 I use 87 kW. If I get 1.9 at 80...

Now if the stretch is 240 miles, I do not make it at 80 mph,... in Western Texas, 80 mph into a medium headwind I was under 1.5 miles per kW, slowed down to 73 and got closer to 1.9 miles per kW.

Spoken as a true EV veteran!

Leaned this exact thing early on with my Tesla. That said, I am very disappointed to hear that at 80mph, cannot make 240 miles. I know you have 22" (same as my order) so your experience would be typical for mine.

I was hoping to get around 260 miles at 80mph on 22"... such is life.
