How to maximize range? Comfort mode may not be the way ….

[zach]

Besides everything listed above, some other things:
-Ideal ambient temperature. Studies show that EV range is maximized between an ambient temperature of around 80F. There is a small drop off at higher temperatures due to excess climate control. Your vehicle range will be much worse in cold weather due to the temperature dependence of the electrochemical properties of the battery (your battery performs worse in low temperatures). It gets even worse at very low temperatures because the vehicle has to compensate to keep the battery warm
-Most critical-speed. Based upon my experience in my model 3, there’s a huge difference in range between any speed below 60mph. I’ve gone 60-65mph on trips to avoid charging, even when highway speed is 70mph. Yeah, everyone on the highway is going to hate you and going slow drives me crazy. FSD will help this tremendously. For short trips (<300 miles) you can reasonably do without charging, it makes more sense to maximize range and go slow. For long trips, it is better to go 70mph and charge more frequently because you spend less time charging than the time you save from preserving range. Furthermore, on a long trip, you will have to stop anyways to eat and use the bathroom. I just always make sure to hold it until I can get to a SC and eat near the SC stop.

love to see owners of $100k+ trucks debating the cost of a few dollars in electricity per year!
Go Green!!!

A Sparty finally achieved in life unlike most others. Bravo.

Go Green, Go White, Still learning to read and rite.

That may in fact be the reason for the pinching! lol

I did some unscientific tests on a ~1500 mile road trip with ride settings. I wasn’t able to figure out exactly what was happening, but it didn’t seem that drive modes specifically affect energy consumption. I did notice the following.

• Ride height has a pretty big effect on energy consumption. Using anything other than low at highway speeds is not efficient
• Battery heating (and cooling?) may have a big effect as well. After one supercharging session, the truck was using about 8% more energy for probably 30m AFTER the charging session.

Overall, I averaged about 420/mile at highway speeds. Maybe around 440/mile while towing a jetski. I think I could have gone 300 miles at highway speeds. I’ll done a full write up someday.

I'm at 8,000 miles and my lifetime is 399wh/mile. Pretty good I think.

FYI: Tires at about 52-55psi, temps constant around 80-85F.

So in another post, it was suggested that the aero caps do not increase range, but the test was very short.

what was more interesting was the effect size of ride height - dramatic increase in energy utilization at higher versus lower.

I have been using a dynamic setting of ”comfort” (chill, relaxed, high). I thought that comfort would translate as better range (less aggressive?). But now I am rethinking.

Does anyone know by testing what dynamic settings yield the best range? I am thinking custom (chill, relaxed, lower) but it’s pure conjecture…Inquiring minds want to know … ?

Not sure why higher energy utilization at higher ride heights would be surprising. The lower your ride height, the lesser surface contact, hence, a lower drag coefficient.

I dropped it into Custom/Lower/Focused and I couldn't tell the difference in my normal driving. I switched it back to Custom/Higher/Relaxed

I am sure if I was driving around corners at speed and being more sporty it might matter? I couldn't tell a significant difference otherwise? *shrugs*

Surface of what? The tire contact patch is the same. The only thing that changes is a few dozen square inches of increased frontal area, all in the bit of greater tire exposure.

"Surface contact" was probably the incorrect term. Lower ride height is associated with better aero due to reduced turbulence underneath. That's why race cars are practically scraping the asphalt.

You're talking tires only and forget the rest of the vehicle. ?? Back to Pine and Derby drawing board for you.??

That's not how aerodynamics works. Much greater drag with added height, air flow under the body is highly nonlaminar and creates lots of drag.
