Efficiency secrets?

[Rblue]

No heat
Conserve mode
Drive slow (sometimes)
Low suspension setting
Proper tire pressure

Anecdotally, my experience has differed slightly.

I usually run with seat heaters on and heat set to 70, typically in all-purpose, this winter has seen a fair amount of heated steering wheel use as well, and at over 5600 miles current average 2.06 kWh/m. The truck has 21's fwiw, that's probably a significant factor in efficiency differences.

I'd be interested to see the data for our trucks in miles driven by configuration (drive mode/height)

Very true. I was thinking the same thing about the warmer weather factoring in over long term averages. Guess we’ll wait for late spring or early summer to see the difference it makes before we contact service.

So I’m further north than you, same coast.

Here’s my last 15min in sport:

Efficiency tip #1:

50psi cold.

 

[Yellow Buddy]

Last night I actually turned climate off and made every effort on the 4 miles each way to the store and back to try and get the highest efficiency I could and only averaged 1.98 over the 8 mile round trip. ?

Efficiency tip #2:
Bigger trips = better efficiency.

In town, I’m rarely above 2.0. The Rivian is actually less efficient in “city” than the Lightning. Jump on the highway for big, consistent miles and I’ll see 2.5+

Others can answer that better for sure since I don't have mine yet.
The thing that confuses me a bit about my situation is I have 2.6mi to go to work. The car sets for 9 hours in freezing temperatures, then I come home 2.6mi.
I'm only preconditioning one direction, yet it really seems to drop very little efficiency for the round trip.
My theory (smarter people weigh in) is that I only charge like 1 time a week and when I do it is to 100% with preconditioning and the whole battery pack warms up. Outside of those charges, many of the trips are so short the battery never warms up much. Preconditioning that one time in the morning still must have some warmth in the battery pack to garner good efficiency.

That is kinda strange. But I don’t know too much about the Leaf battery pack or the battery management system.

I figure the 21’s vs. 20’s vs. 22’s makes a difference for sure, but I’ve seen folks with the same wheel/tire set we have getting better efficiency than ours by a bit. Good example is two posts above this one. Yellow Buddy lives in the same climate, or maybe marginally colder, and he gets amazing efficiency by comparison.

My car is apparently a freak though. I recently found out my max range on 22s is larger than some folks on 21.

Efficiency tip #3. Look for panel gaps, uneven panels, and/or air leaks. I had some pieces that were slightly off. After getting them corrected my efficiency was noticeably higher.

All good considerations! My post was to highlight that one can run climate control features in all-purpose mode and hit >2 kWh/mile efficiency.

I would guess that battery temp/condition before starting on a trip is also a factor worth adding to the equation. However, you keep your truck in a garage, so that probably isn’t a factor in the deltas between the numbers we’re seeing.

My ~3500 mile average since pickup late Sept is 1.73 m/kWh. 75% city driving, 20" AT, 85% all purpose mode and the rest sport, never really used conserve, NYC weather (mostly cold since Sept, some days a bit warmer in the 50s, a bunch of days below freezing).

Some factors I noticed with reduced range:
- Usually have heat on at 72, heated wheel and seat on.
- Work commute is short so mostly shorter trips which isn't good for efficiency.
- I am pretty aggressive with the throttle.

On the days where its in the high 50s and I have the climate turned off I see my efficiency go from 2-2.5 m/kWh so the resistive heater really draws a ton of power. I am fully expecting to get improved efficiency once warmer spring/summer days come around.

 

[goldburger]

do you all baby the throttle? i've started doing that and have been getting about 2.15 but it's significantly less fun to drive lol

 

[Jack Smoke]

Does your truck have a tonneau cover? That’ll make a difference. The faster you go the more difference it makes.

Try all the recommendations above, and experiment with a medium drive. Keep the speeds low! That’s one of the most critical things. Under 65 will give you the best results, assuming no winds.

Then, try pre-conditioning and see if that brings things up (because Winter).

If neither of those bring your efficiency up, call the SC. We’ve see situations where trucks are misaligned enough that, while not causing issues driving, are dramatically impacting efficiency. Improper toe-in is usually the culprit.

This is what I've found as well. I started seeing reduced numbers and thought 45 psi wasn't that big of a deal. I aired everything back up to 48 cold and got a noticeable increase in efficiency. I have been disappointed with Conserve mode, not really noticing a huge difference vs. AP low. The projected mileage at destination is different but when you get there it's not.

I’ve tried being super gentle lately over the last week or so just to see how high I can get that efficiency. Haha I was expecting to see up around 3 driving the less fun way! But like others have said, winter, ~30 minute commute, and the lack of real preconditioning might be the biggest culprits here.

No tonneau cover yet. Wish we had one though! I’d definitely try testing with and without it!

read through these. on the last page is my DIY tonneau. $125 and 1.5 hours. It’ll last until the manual arrives.
