Poll for Dual/Tri-Motor Vehicle Efficiency at 60 MPH in 60°F

This poll aims to gather real-world efficiency data for dual/tri-motor electric vehicles under consistent conditions. The goal is to measure efficiency (in miles per kWh [MPK]) while cruising at 60 MPH on flat terrain at approximately 60°F (no wind). To ensure accurate and comparable results, participants should follow a simple testing procedure. First, reset Trip B (or a similar trip meter) once the vehicle reaches a steady 60 MPH, drive on a flat road for at least 10 miles, maintaining the speed 60 mph confirmed via GPS. During the test, observe the highest and lowest efficiency readings and determine the closest representative value. Submit this value as your result. This data will help build a better understanding of real-world energy consumption across different quad-motor vehicles.

Tire pressure as close to 49 psi (cold) as possible.

-if not using the 20” OEM Pirelli, make a comment with Rims/Tires being used.

Correction factors for different temps/elevations:
Add, if
+0.1 MPK if 53°F
+0.2 MPK if 46°F
(-0.1 MPK if 67°F)
For every 1,000 feet above MSL, subtract 0.06 MPK

No takers?!?

I don't have 20's and winter is a bad time to try and ascertain this.

A good portion of the US has been below 60 degrees for months and will continue to be. You have spelled out a very specific test procedure that people may not be interested in executing. Where I live, and many others, there is no flat 10 mile stretch of road nearby. You gave people barely 48 hours to read your experiment, find time to do it, and report the results. All of this limits the possible number of people who might have responded. It's not that surprising that you have zero responses so far.

Some reasonable observations, added correction factors for those with variable temps/elevations…can also add details for any different tire/wheel sizes, focus on 20” tires since there are so many options, very few options for the 21/22” group.

 

[ksurfier]

Added MPK options up to 3.5…

This poll has limited participants, hopefully more can vote so we have better representation:
However so far this implies following ranges:
Standard Dual: 225 miles (real world tested at 240 miles at 70 mph)
Large Dual: 310 miles (conflicting info on actual range)
Max Dual: 336 miles (real world tested at 341 at 70 mph).

Poll closes soon, only 5 entries so far…
