you have to fly an electric plane. The EPA rating on the plane is 500 miles so you should be good...

That’s how it was in 21 and 22. They may have since changed the advertised range but it seems Porsche, MBZ and BMW all overachieve on range.

Is that really allowed. What's the point of this governmental regulating agency if one can choose to ignore it? If it's just a standard to be ignored, we'll then it's not a standard. Following that line of thought, anyone can make up there own overachieving/underachieving standard ... ridiculous.
They use a lower number though, not higher. If someone wants to undersell, that's their prerogative, just like a software limited pack would be.

Yes, anyone can do anything they want. That doesn't make it helpful.
No, the only range you can advertise in the US is the EPA approved one you get following the rules. But the rules do allow the manufacturer some leeway in getting/reporting a lower range figure.
Wait, now we're saying a more easily achievable in the real world number isn't helpful?
It's not helpful to the guy trying to sell the underrated car, but it is handy for whomever buys it...
It isn't helpful if you are trying to use the EPA rated range to compare vehicles to see if they will meet your needs. Which that is supposed to be its purpose isn't it?
Sure. But isn't this thread based on the premise that using EPA rated range to judge if a car meets your needs doesn't work in the first place?
Range due to efficiency yeilds a completely different experience than range due to large pack size.

This statement started me on this was this line of questioning:
I don't believe it's true, that Taycan advertises a rated range of 199 where one user can get 58% more! So I think the OP of that post is not using real numbers..
Unless all the Google result are spam, it's accurate.
Taycan has a two speed gearbox which I think impacted the EPA test

That's exactly what I'm saying. It's not helpful for the consumer of this information that the number is not reliable. As I stated above, I don't believe the numbers used by zer0t. If they are true, how usefull is it to advertise a range, but the real world range is 58% more?
That seems to agree with the test results Edmonds achieved for the 2020 Taycan: Edmunds Tested: Electric Car Range and Consumption | Edmunds
But not for the 2022 Taycans. So you can't even use the EPA range to compare vehicles from the same manufacturer.
Of course the Edmonds test isn't following the EPA procedures, it is more real-life.

So many numbers.
Wikipedia defines specsmanship:
Specsmanship is the use of specifications or measurement results to suggest or establish putative superiority of one entity over, especially when it is inappropriate. It is commonly found in advertising of high fidelity audio equipment, automobiles, digital cameras,[1] electronic display devices,[2][3][4] and other merchandise.
The overdrive allows it to be efficient at highway cruising.
EPA has lower average speed but more acceleration and braking compared to highway cruising.
I'm using real numbers. According to Edmund's it was 203, but I'm pretty sure when I got the car it said 199, but I'll look for the sticker. The Taycan is tied for 21 in the Edmund's article at 323 miles of tested range.

Which EVs have the best electric car range? The EPA provides range estimates for every electric vehicle, but they don't test EV range in the real world -- and Edmunds does. Read all the latest real-world EV test results from the Edmunds experts.

I'm pretty sure Kyle O'Connor, Taycan fan, did his 70 MPH range test on it as well.
ETA: I see the Edmund's range test was added.
There could be more than that. EPA may require driving in certain 'driving modes' or averaging them, and Porsche has non-economy modes that give worse results than the 'Eco' that one would use while cruising on the highway. They don't need to compete on range or cost, so they don't, and they also assume, correctly, that most of their buyers are much more knowledgable about such details than an average car buyer.
