Who achieves their EPA rated Wh/mi?

[balefire]

I was discussing the recent Porsche Taycan dismal EPA range on another forum. Someone challenged me to provide data regarding the real world mileage with EVs.
Tried searching and didn't find it.
So here is a go at getting some data real world.
References below.
Happy to update references if anyone has the Model 3 or new Raven data.

• Model S 60 (s/w limited 75): 210 rated miles * 295 Wh/mi = ~62 kWh usable
• Model S 75: 249 rated miles * 295 Wh/mi = ~73.5 kWh usable
• Model S 60D (s/w limited 75): 218 rated miles * 285 Wh/mi = ~62.1 kWh usable
• Model S 75D: 259 rated miles * 285 Wh/mi = ~73.8 kWh usable
• Model S 90D: 294 rates miles * 285 Wh/mi = ~83.8 kWh usable
• Model S P100D: 315 rated miles * 314 Wh/mi = ~98.9 kWh usable (* Estimated Wh/mi)
• Model X 75D: 237 rated miles * 320 Wh/mi = ~75.8 kWh usable
• Model X 90D: 257 rated miles * 320 Wh/mi = ~82.2 kWh usable
• Model X P100D: 289 rated miles * 342 Wh/mi = ~98.8 kWh usable

On my old 2014 MS 85 with aero wheels.
Wife never got EPA mileage.
I got it when I consciously tried by avoiding a lead foot and minimizing cabin HVAC use

Over 100k miles I’ve averaged 313 wh/mi on my S75.

Your chart is incomplete. The rated range for my January 2016 S90D is 288 miles. 294 didn't happen until after the refresh.
After almost 4 years it's around 272 miles.
My lifetime trip meter says 297 Wh/mile.

I can hit the epa numbers either if:

on my daily commute which is 20-30 mile round trip over hilly ground if I intentionally drive gently and turn off the climate controls. In bad weather (too hot / or especially too cold) I can and often do use 2-3x the rated power.

Driving on the highway with cruise control set at 70mph it is pretty easy to hit the rated economy numbers, especially if I turn on and off climate controls. It would be nice if they had a slightly better focus on keeping humidity down. The "auto" just seems super dumb.

Overall, in commuting, it is a pleasant place to spend time but not as efficient as an "economy car"

Over 98,000 miles on my P85 and my lifetime trip meter is 302wh/mile. It was at 319 wh/mile when I bought it (21" wheels), Changed to 19"s and it made a huge difference.

 

[aerodyne]

Missing an entry for 85D. It is 292 Wh/mi, 270 mile range.

On my mid 2015, cpo, with 32k miles, and 266 mile range....I got 313 on 5k road trip. Since then averaged 296. Current average over 1 year and 13k miles is 301.

I agree the HVAC could be smarter. I noticed recently that in Auto you can toggle recirculate without knocking it out of Auto. With recirculate on with Auto it’s not to bad.

Also Enable Range Mode so it doesn’t waste watts heating the battery.

About 16,000 miles on my S75 and am currently at 292 Wh/mile.

I thought range mode actually actively heated the battery (to operate in a temperature range where it has access to the most energy), and so using it for short commutes was counter-productive?

This non-authoratative post indicates that it heats the battery to a higher temperature than normal mode.

For now, at least, someone else is paying for the power (free chargepoint terminal at work and / or supercharging). Once I get solar, I'll have paid for the power all in one shot.

When I had a Model S I could get rated range if I set the cruise control at 65. The problem is that in rural Utah the speed limit is 80 mph on the freeway and at that speed you will never get rated range.

With the build out of the supercharger network its not really a big problem for me, just something to be aware of.

I think that the EPA numbers are much more useful for comparing cars from different companies. It seems pretty obvious that the Tesla model S is going to go much further on a charge than any Porsche or Mercedes Benz or BMW.

Ya know, I think that just about sums it up. I have a LR AWD model 3. I've had it for just over 13 months (Nov 6, 2018) and have approximately 5,000 miles on it. In that 5.000 I've avg'd 250wh/mile which is weird as in the winter I seem to see over 400 wh/mile on the energy page. In the summer it's not unlikely to see 210 wh/mile. I suspect someone coming from a car getting 27 miles/gallon something like the Model 3 would be a nice lift as far as cost/mile. I came from a 2012 Prius Advanced and got on an energy sparing tire easily over 60 miles/gal. So, compared to that the Model 3 is an energy hog. In the winter I can lose 2-4 estimated miles on that charge just backing out of the garage.
In the effort of transparency. An ICE car's winter heating is a byproduct of internal combustion. It's free. Electric heat is anything but free. The good news is it comes on immediate rather than making the driver wait 15 mins.

Where's the "It's hard not to beat the EPA" question?

I have found this chart on somewhere back in spring, here is a copy of it... sorry, it’s in metric...

I can visually see with range mode off it runs the battery heater in the app while driving and does not when range mode is on. I did not check the difference while charging. But I think it heats the battery if it’s cold range mode or not but perhaps it heats to a different level.

I also clearly see regen restores much more quickly with it off. Because it’s warming the battery.

Couple posts in your link confirm my experience. I get better wh/mi on short commute with it on. Because it’s not trying to warm the battery.

I don’t like that it disables day time running lights. It may behave differently today.

BTW is there an indicator in the car when the battery is being heated? Seems odd that the app has more info than the car.

I have a lead foot but don't like my cabin toasty.

 

[YYZ-IAD]

2018 MS 100D - I run close to EPA on average - but big seasonal difference (Buffalo/Toronto temps). I generally run on "chill" acceleration

Summer: 300 Wh/mile
Winter: 350 Wh/Mile (16% worse)

its from Tesla Range Table - Teslike.com
and it does metric AND imperial.
But the only thing EPA is at 77 mph.

...real world mileage with EVs...

I've been consistently getting the advertised mileage since 2012 Model S, 2017 ModeX, and now 2018 Model 3 as long as I don't go aggressive with my driving. I've been using automation as much as possible such as simple cruise in 2012 and Autopilot since 2017.

I've been a hypermiler with my former ICE and I still carry that habit to Tesla as well.

Here's an example of 2018 Model 3 RWD Long Range:

220 miles were driven on the road but it only consumed 208 Rated miles on the battery gauge. The speed was anywhere from 70MPH in Central Valley California to stop-and-go in downtown Los Angeles. This trip involved climbing up southbound 4,144 foot Tejon Pass as well.

As a matter of fact, I consistently did not get the advertised mileage with my former ICE but it's the opposite ever since I switched to Tesla in 2012.

It's not that hard.
