100+ Mile Range Efficiency Challenge

[Formosan]

Hi all, I am trying to collect data on how different drive modes affect range using real-world data, which I hope to share at the end. To start, I will share my own data from the past 150 miles below as part of the "100+ mile range efficiency challenge." To achieve the MSRP range of 410 miles for my vehicle, I would need to get ~2.92 mi/kWh. So I was pleasantly surprised that after ~150 miles, I am getting ~3 mi/kWh. If you would like to participate, I would appreciate it if you all could post a screenshot and include the parameters of the trip as I have outlined below. (I am also planning to do another 100+ range test next week using Sport mode)

Model: R1S Gen 2, Dual-motor, max pack
Wheel: 22'' sport
Drive mode: All-purpose
Height: Standard
Ride feel: Moderate
Regen: Moderate
Stability: On
Ambient temp: 48-60F

Total miles: 149.5
Efficiency (mi/kWh): 3.03
Average speed: mixed freeway/city speed (1-65 mph)

Wheels?

Speed?

Completely forgot about the wheels (such an important one)! I just added that to my original post. Speed is a difficult one to control IMO. I drive freeway/city to work, so 50/50.

For driving temps are we talking motor, ambient, battery, what? If ambient 48-60C is pretty damn hot.

Speed range and avg speed is a must have.

Added the speed and my bad on the temp (48-60F) - not sure why I was using celsius.

I think driving a flat piece of road or highway in both directions for a half an hour at constant speed would isolate the metric for each speed, height or mode you are trying to test.

The question for me is under what condition can one achieve their MSRP range. It is never clear to me. At least for me, it is comforting to know that the conditions/parameters + whatever confounding factors that I am driving, that efficiency is achievable! It’s just my first test. As long as I can be consistent with my daily route, I can use it to test various modes.

I'll put my results in here when I have some, but I think the most important temperature measurement is battery temperature.

It could be 40 degrees outside but if the battery is 65 degrees the efficiency will be substantially better than if the battery is at ambient 40. This could happen if your garage is warm but the outside air is cold when you start the trip. This will be my situation regularly in the winter.

I’ve posted my efficiency results many times before but here they are again. This is on a 165 mile route I do frequently. Mix of 70mph freeway and 55 mph rural roads. Avg speed is 54 mph. I’ve owned a Gen 1 quad and now a Gen 2 dual R1T

I can't get myself to drive efficiently and would skew your number way down. Bought an ev because of 835hp and I try to use a lot of it whenever there is an opportunity

This data is - again - fantastic. I recall seeing your early G1 data and was very pleased that mine tracked your graph. Now seeing the G2 data, I'm very conflicted.

G1 hits EPA #s pretty regularly in moderate ambient temps, and generally exceeds them if speeds are kept low (per your 54mph).

G2 hits EPA #s at warmer ambient, but doesn't look like it tracks to EPA until 10-20 degrees warmer than the G1 did.

I've been a bit puzzled over that too. The Gen 1 Quad has AP and Conserve modes. I wonder if the EPA is a blend of the two. Gen 2 Dual is essentially always like the conserve mode on a steady speed drive like this. For purposes of clarity, I've only included data where I used the Gen 1 in conserve to compare to Gen 2.

I will add in that my vehicles have the standard Pirelli OEM road tires. 21" on the Gen 1. 22" on Gen 2.

Another note to add. The heat pump on the Gen 2 appears to provide no efficiency benefit.

All purpose data (RED POINTS) included here;

Actually good point - I think the EPA #s on the G1 were based on AP, not Conserve, in which case the G1 was hitting EPA in slightly different temps (wasn't original G1 Quad range 314 with 21" wheels and later revised up to 320-ish?).

This.

The biggest variable in a study such as this on a diverse forum is terrain. My numbers would pull this study way down - I have a ~700 foot elevation change from home to work, and I would have to drive 90 minutes to be on a suitable flat road as a "standard". No, downhill regen does not make up the uphill extra energy usage.

Thank you for posting it again. My first time seeing it. A couple questions about ur graph just so I am interpreting it correctly: 1) what is each data point represent (eg., the first graph, R1T gen 2, you have 11 data pts on the graph, is each point a trip taken at that particular temp for 165 mi)? 2) is your R1T gen 2 data from All-Purpose mode?
