I looked through the independent Taycan tester's testing parameters. The one important variable I recognized for which they did not give a datum was tire inflation. You can create a lovely increase over real-world conditions by overinflating tires.

@TradingInvest , you disagreed, can you explain how aero loading in a wind tunnel would be a factor of the car is strapped down to the dyno and therefore not actually pushing through the air?

check out the cyber truck being tested against incoming traffic:
Top Teslas on Instagram: “Cybertruck In GTA 5 • Follow us! @topteslas • #tesla #teslamotors #teslamodel3 #teslamodelx #teslamodels #teslamodely #model3 #teslasemi…”

just watch them play this in some congressional hearing about Tesla Autopilot safety.

It is (or at least could be)pushing through the air. You’re just looking at the wrong reference frame. It has to push through the air in order to not slow down/go backwards.
I wonder if Porsche will put in writing that a Taycan buyer will get way more than 201 miles.... I'm sure they will give refunds if they are wrong.
I suspect that' it's near impossible to keep a car centered in a set of dyno rollers without being strapped down.

It would make sense for the dyno to measure the net (aero) drag force (it is transferred to the dyno rollers after all) and adjust the torque load accordingly. That way you can properly account for aerodynamic drag while doing controlled testing. I don't know if that's what they actually do, but it's what they should do, or an equivalent where separate wind-tunnel tests are done to record the drag force and then just play this back as additional drag on the dyno during the test.

Manufacturers have to do their own EPA testing. EPA just reviews and audits.

Again, I doubt this is possible… keeping an accelerating car centered on rollers without straps would be very difficult.
Hence my question: How does a wind tunnel make a difference if the car is strapped down?

@scaesare is obviously correct but this is drifting OT
Price action lately is GREAT.
the trend is KICKASS
just look at the chart.
SpaceCash Holdings today has updated their price target for TSLA to $666 by 3Q 2020. This is a conservative estimate

I can understand a little his daughter feels. My sister-in-law law has never been a car person, but loves her Model 3 LR. I asked her recently if, after >1 year, she is still liking it, and she said she loves it even more. Teslas have a way of making car-people out of many who never would be otherwise.
@scaesare, I re-read your post, I was wrong. Air resistance is an important factor for milage, but when the car is strapped down, wind tunnel doesn't make any difference. So you are exactly right.

No there’s not, I am a regular on that site and you have a lot Tesla owners making noise in that thread. Actually the Tesla owners ( own Porsches and Teslas) out number the Porsche owners on the Taycan forum.
Are the potential owners happy? No, but the number release was the number predicted though many were hoping for better.
