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

2016 MX P100D is wife's car that I drive on family trips.
Wife never gets EPA mileage.
I get it when I consciously try by avoiding a lead foot and minimizing cabin HVAC use

On my LR Raven X with 20” OEM I was averaging 270 wh/mi before winter set in. Now it’s more like 330 wh/mi. EPA is around 308 wh/mi.

EPA does not factor in heat or cold weather.

My Model 3 was 230 wh/mi summer and 270 wh/mi winter with 19” OEM AWD (stealth). EPA was around 241 wh/mi

it really doesn’t matter if you get above or below EPA. If you get worse than EPA on a Tesla you’ll most likely get worse than EPA on the Porsche by a similar margin. It’s just a comparison tool.

EPA testing does not use any HVAC.

I have a Model X P100D and averaging 450Wh/mi. No reason to try to achieve EPA rating.

On my Porsche GT3 even with a lead foot, I get EPA mileage.

Similarly my wife never tries to achieve the EPA rating. Lifetime Wh/mi is 420

Easy if you drive at EPA specifications. But who drives like that? It's just a benchmark

I was referring to a Porsche EV.

Your wife might get 120 miles out of a Taycan.

You didn’t state if your was Raven or if you had 22” wheels. Performance EPA on Model S/X is a significant hit.

It drops from 328 to 272 miles range on a Raven to include Performance and 22” wheels. That brings it to 368 wh/mi for EPA. If it’s a non Raven, Performance with 22” wheels it probably approaches 400 wh/mi to meet EPA. Your wife might not be that far off. But we have no idea because you left out important details.

Keep in mind that ICE vehicles regularly game the EPA ratings by designing their engines/transmissions to work best at the speeds the EPA tests at, which is why when you go above those speeds, the rated numbers don't align at all.

Not sure if EVs are subject to the same trend.

I had, for a while, a 27 mile commute across the top of Atlanta and achieved the EPA rating in the summer.

However, most of our driving is highway, so we tend to be a little worse, on average. Our 'lifetime' average over 33K miles is 259 W/mile

M3 lmr 18 areo, Rated 247. I routinely beat that during summer commutes, often averaging down in the 195-200 range. With winter, rain, hvac, now it's more like 250-270. 20 mile rt.

 

[Simon21]

I have had 4 EVs. The Tesla gets less than the rates miles. The other 3 non Tesla got more than the rated miles

 

[wdolson]

I have a 2016 S, but in decent weather I often get around 285 Wh/Mi. My lifetime is 302, but it's been coming down since the first year.

 

[Yinn]

If I turn HVAC off, I can get EPA almost every time - if I stay under 65mph. I can beat EPA if I enable chill mode and ease up on my foot. If I drive normal, setting everything to auto at my liking; I'm routinely 25% over EPA ratings.

I have a Model X P100D and averaging 450Wh/mi. No reason to try to achieve EPA rating.

This is also my average with Raven P100D 20" blizzak winter tires

Car seems to be doing better as it ages. I can achieve 330-340wh/mi on the OEM 20" wheel/tire combo in normal SoCal highway/local driving, even with my lead foot. Not too far off the rated efficiency. With some effort, I can bring it below 320wh/mi. This is for the Model X.

The Model 3 is a different story. 320wh/mi is my average over 28k miles. It's very difficult to drop it below 300wh/mi.

What year is your X?

As your tires start to wear you will get better efficiency due to lower rolling resistance.

March 2017. X90D.

2018 P100D X, 22" mine varies quite a bit on numerous factors but i'd say my average is 450-500
