Electrical Efficiency (how many miles/kWh are you achieving)

[Riviaenz]

R1T, mostly on Conserve driving mode, with factory original 21" tires = 2.22 miles per kWh.

I've showed you mine. Now kindly show me yours.

Are you tracking indicated consumption or actual energy used to power? There’s some loss during charging. For example, for a session where the in vehicle Energy app reports 26kWhr put into battery + for temp management and accessories, a charger may actually report 29-30kWhr dispensed. You can even see that with the Rivian home charger although it doesn’t fully log actual energy dispensed. PLUS Rivian also uses energy while in standby, idling, or even AFTER it’s finished charging overnight dropping the average (you can also see that in the Settings, Drivertrain, or Energy onboard apps.

In our case, tracking actual energy dispensed vs. miles driven over 12,550 miles we’re averaging 1.55mi/kWhr.

I’ve seen our driving efficiency for some drives to as good as 2.72mi/kWhr and generally it’s around 2mi/kWhr; averages out to just under 2mi eventually.

This is while logging energy dispensed since that’s what we‘re actually paying for at home or at non-free L2/L3 chargers on the go and not how much energy is put out at the wheels ?. What’s really cool is we’re averaging $0.148/kWhr even paying for DCFC on road trips (which have been mostly towing).

This Tripmeter slip‘s first 500 miles were towing one of our trailers. During that trip I averaged about 1.5-1.6mi/kWhr towing. I only reset Trip B when I start a new towing session - I used it to track and record mileage and efficiency while towing and I use Trip A to reset after each charging session to see how I’m doing on a daily basis.

Usually 1.xx. Occasionally 0.xx. Never 2.xx or 3.xx.

I wanted to compare my lifetime trip odometer values to the total energy added to the vehicle which you can find in the Rivian app. This turns out to be the true cost of ownership since it includes the charging losses that aren't picked up in the trip odometer.

I have never figured out what Rivian includes in the trip odometer efficiency (just motors but no cabin?), if one takes 9332 miles divided by 4250.8 kWh you would get just shy of 2.20 mi/kWh which hopefully include cabin and battery conditioning. But since I wish to include the full cost of charging in my efficiency I can pull the charging history from the Rivian API and find:

Lifetime energy added: 4376.8 kWh
Lifetime efficiency: 2.13 mi/kWh
Lifetime range added: 9694 mi

This is a mix of DCFC and L2 charging so it is probably safe to derate your Rivian reported efficiency by 0.9 or so to adjust for charging inefficiencies and other energy uses not included in the stated efficiency.

that is not very good for 21s and conserve mode.

mine was 2.28 kWh after 10000 miles on 20 AT tires. i recently took a trip to LA and that dipped the efficiency so not stand at 2.19 kWh.

based on this small sample size, 21s do not seem to be getting very good efficiency and 20s are doing surprisingly better.

Just had my one year ownership anniversary on 12-26-2023 pretty much all on standard mode and height

Agreed. My observation is the efficiency reported in trip summary overestimates 10 to 15% vs the real world efficiency.

Late to the game for Gen 1

DM Performance max pack - 20AT - first 1000 miles - 3.01 mi/kwh

Summer + high altitude (live at 8300 commute to 5300 ~55-65 mph) - hit around 4 mi/kwh on way down (and 2ish on way up)

Will be interesting to see winter

 

[JR1T]

1.9-2 mi/kWh in All-Purpose mode, mostly around town driving.
2.2-2.3 mi/kWh in Conserve, only used for road trips where I'll need to fast charge.

QM Large Pack with 20" ATs. I'll usually drive 75ish on the highway.

I pulled this data from Electrify, not the onboard calculator.

 

[Foreman Grill]

Does your efficiency numbers go down if say you are sitting in the parking lot for awhile but with the car on?

 

[Type_R]

Granted I only have 1,583 lifetime miles. I'm at 2.76 mi/kWh with 21" PDM in AP mode with no aero covers since the first 289 miles and at standard height most of the time. My current trip from my last charge reset, is at 3.06 mostly mixed driving with temperatures ranging from mid-80's, 90's, and today a high of 103 with 86 miles on the trip meter. The best so far since I've owned the R1T.

Dual motor performance, 22 inch wheels, 3000 miles mix of about town (live at 7,400 feet, drive down to around 5500 feet and back) and back and forth to our mountain cabin at 11,400 feet. Avg 2.6 to 2.7.

 

[Tony R1S]

QM, 21, no aero, AP standard height.
2.58 lifetime ~19K miles.
Running boards installed ~3K mi ago.
~2.35 on last 1500mi

Had front left half shaft replaced recently, and seems efficiency has dropped from average 2.45 to 2.35 since that fix. It could be due hotter weather (more AC use) as well.

Just crossed the 5k mile mark and averaging 2.71 mi/kWh thus far. Performance DM Max Pack with 21s (aero covers removed) and manual tonneau. Recently did a road trip around New England with a lot of back-road driving in Maine and New Hampshire and that 1300 mile trip average 3.08 mi/kWh which I was really impressed with. The brutal summer traffic probably helped boost the average a bit while crawling down 95/495 at 35 mph on the way home. I’m definitely seeing closer to 2.5 mi/kWh or less at 75mph and that’s drops closer to 2 flat around 80mph as many have pointed out.

2023 R1T
Large Pack
20" AT
99% in all-purpose
standard ride height
standard regen
80% city
20% highway
0-12k miles: 2.28kWh
12k-20k miles: 2.18kWh
17 months of ownership

im thinking its mainly due to tire wear. currently at 7/32

 

[xpunch]

2023 R1T Dual Motor Max Pack 21" wheels. Just over 6000 miles and averaging 3.2 m/kwh. I drive in all purpose with auto height adjustment
