This weekend i had a mini trip to LA and averaged 2.6+ miles/kWh on 20 ATs with conserve mode which made me wonder if conserve mode efficiency has secretly improved… and then this video popped up on recommendation that tells a similar story…





Tl; Dr is that this guy did 2.77 miles/kWh on 22s over a 900 mile trip.

Also Alex on Auto averaged 2.6+ kwh on all purpose mode with 21s. Has efficiency

Are you determining the energy consumption based on the trip meter? Any idea what the total % of a charge you used over the 900 miles (ie like 250%)? I've seen a few times where the trip meter seems to have a calculation error in the energy usage, so just trying to think if another way to confirm the consumption you saw.

Hm yeah my number was just based on the consumption meter. This video however was not mine

I 100% believe my range to be well beyond 310 miles (22" wheels) in my R1T if I'm driving in conserve mode and below 70mph (average speed).

Seems like the more I read car magazines the more they knock the R1T's range.

Love how MT says the "lightning has a longer range with its EPA 320 miles" (didn't know EPA estimates were a reliable thing)... I have zero belief in that range estimate and would encourage more Lightning owners to post there ranges, average speeds and kWh consumption.

EPA range is done in All-purpose mode, not conserve.

I have been incredibly impressed with Conserve Mode so far tbh. Not only is it very efficient, but it's also surprisingly pleasant for driving around. I have found myself staying in Conserve much more than I expected to as it's very comfortable for driving around town. I thought I'd only use it for long range highway driving, but that's not the case at all.

Major props to the Rivian engineers for the technical aspects of the clutch disconnect that allows for Conserve Mode and how much it impacts the vehicle efficiency.

Rivian service told me not to drive around in Conserve unless I absolutely needed to for extra range. He mentioned tire wear, which should be alleviated somewhat with rotations. I also assume it would put uneven wear on the front motors since the rears are completely disconnected.

Just seems odd this would be their recommendation with a prominent drive mode. There's no indication on the screen it should be used sparingly.

In conserve at 55-70 mph on a mix of freeway and state highway I'm consistently getting 340 miles or better. 368 miles of range one time on a 155 mile run back from our northwoods cabin, 2.95 miles/kWh. This is on the 21" road tire.

EDIT: Some asked what size battery pack is used in the range calculation, I used 125 kWh.

These ranges are crazy. Sure does a great job of curing any range anxiety.

Seems really odd. For tire wear, how is it any different from a normal rear or front wheel drive vehicle? Regarding motor wear, is anyone expecting these motors to "wear out" before the 175,000 mile warranty period? I seemed to think that outside of total failure for one reason or another, electric drive units are basically bulletproof.

What is everyone using for “available kWh” when calculating range based on a driven efficiency, 135 kWh? I seem to remember a video mentioning available battery is closer to 125kWh…

if I calculate a “100%” battery using the consumption listed in the trip details and the % battery used it does seem to be closer to 125 kWh available, but also hasn’t been totally consistent (but could be rounding errors between a full percentage point and a full kAh).

I use 127 as I believe that's the actual available capacity. It might be 127.7 so 128 might be a more accurate number to use.
