TLDR;
based on the some of the numbers used on this chart for the 2021 taycans I don't give this report much credibility.

On numerous long distant trips in varying conditions I have never seen numbers close to 300+ miles per full charge at similar speeds.

Man even in range mode at 100% battery on all highway I’m lucky to get 215 out of my Turbo with mission E wheels

Hello!

Planing to buy EV, and as I am now driving Macan (and I am happy with it); I am quite close to buy Taycan Cross Turismo. Two times per week I am driving from my home to work; one was distance is 254 km. It is divided as follows: 10 km city (50 to 80 km/h restrictions), 190 km motorway (130 km/h speed limit; I am usually driving to the limit but almost never exceeding 140 km/h), and 54 km local road (restrictions 90 to 50 km/h). As I have home chargers (and solar panels) both at home and at workplace; for me, it is OK if I am going to arrive with 15% of the battery at the destination.

Now – is Taycan Cross Turismo OK choice for such distance driving? The other choice I am considering is Mercedes EQE, but – as you can imagine, Taycan is so much more desirable…!

Any advice is appreciated, thank you very much!

I have a Taycan 4 Cross Turismo and even in Winter I would always get over 300 KM out of the Car, and would in reality expect 320 - 350KM . I live in Ireland so the weather is never very warm. I drive in Range mode on the Motorways and in Normal otherwise and would always be doing the speed limit or even slightly above. I would not be at all concerned about planning a 260KM journey one way in my car if i had destination chargers at both ends of the trip.

I also agree that the Taycan is a much nicer drive than the EQS and being an estate is even more practical when carrying unusual shaped loads.

How do you guys get more than 230 miles? Even in Range mode with everything off I get 230-235. Beginning to think they didn’t fit the big battery! In winter I got 205, cold in Scotland, but in the 24 degrees of global warming I’m still only 235….

 

[Ztarman]

Do you limit speed to 50 mph?

This query is in Kilometres not Miles. 320 KM is 200 miles.

I suspect that it is a combination of terrain and temperature. Here in the part of New York where I live and mostly drive, it is largely flat with very gradual inclines. In the non-winter months, I get about 275 miles at 85%. Reliably. When I drive longer and head west, I have to drive on more mountainous terrain, and that drops. So my range drops there, because you don't gain from the downhill slopes what you lose from the uphill climbs.

This is the important bit. You drive on the speed limit
What is your average on a long journey on motorway as there are not many long motorways in Ireland?
When you are driving on range mode at 130-150km/h you won’t ever drive 300km.
You might see 320 to 350km on your guessometer but you can’t do it.
The test that they did is at 70 miles/h so 110km/h.
At that speed on French highways you will fall asleep. And in Germany you’ll be scared by cars flying next to you.

did you read the chart? it says in the US and calculated in MILES

Also:
- EVs Fall Short of EPA Estimates Way More Than Gas Cars in Our Real-World Testing (caranddriver.com) - the latest print issue has a graph with +/- vs EPA based on C&D's own testing, but that seems to be absent from the web site/article
- EV Highway Range Can Be Very Different from the EPA Numbers (caranddriver.com) (from last year's issue)

C&D's numbers don't seem to align with EV Insiders'; when in doubt, I'll go with the non-YouTubers. :-|

Car and Driver 75 mph, Moloughney 70 mph. I don't know whether that is enough to account for the "non-alinement", or not. One nice thing about Moloughney's tests is you can watch portions of them on video.

Also, seems like defining and measuring "real world highway range" has the same lack of precision as that of "battery SoH".

I meant even on the quoted ranges - the C&D data for Rivian (which is an exact match*) does not seem to align with that of the others:
C&D: R1T 280 real vs 314 EPA, whereas InEV: 254 vs 314.

*For other brands, C&D's on-test models were different - Lucid Air GT (410/516) vs Air Dream (500/520), MB EQS AMG (277/290) vs 450+ (395/350) and so on. There's clearly a pattern - "ze Germans" tend to underestimate their efficiency, whereas the Americans do the opposite.

Also, seems like defining and measuring "real world highway range" has the same lack of precision as that of "battery SoH".

Yup. (And ugh, not that thread again.) The C&D paper seems interesting (it's behind an expensive paywall), as they seem to indicate that adjusting EPA's fudge factor could produce more accurate range predictions/EPA rating:

"A range discrepancy between EVs from different companies might not be as extreme as the numbers would suggest. "400 miles of stated range for a Tesla and 300 miles for a Porsche is pretty much the same number at real highway speeds," VanderWerp said.

The paper recommends that the EPA shift the reduction factor closer to 0.6, which would result in range estimates that closely correlate with the results of the real-world efficiency test. "

290-300 miles is absolutely doable. I have a regular route I drive with fairly rural roads where I aim for 65mph (I set the adaptive cruise, and there's no passing, so sometimes it's a bit less). It's about 20-25 miles each way, so enough for me to get a decent average for the trip, and hitting the 3.6-3.8 mi/kWh is fairly common for me, even though I'll usually have either the windows down or the AC on. Of note is that this is with the ST body and 20" aero wheels.
