R2 Highway Efficiency Test: 80 MPH vs 70 MPH Changed Everything

[mkhuffman]

Generally agree, the available evidence is still limited, but that is not the same as saying there is no data. Specific-speed efficiency readings, road-trip results, independent testing, EPA figures, ABRP modeling, and aerodynamic comparisons all provide imperfect but useful evidence, which is open to scrutiny, but still worth evaluating rather than dismissing outright.

Is this Ken, or is it an AI bot? Sounds like a AI bot response to me.

Dave, you are well known and definitely respected in this forum. You are always civil and positive in your engagements. Thank you for being here.

The OP has been here a long time, but in his time here he consistently provides information he claims is factual when it is based on almost nothing substantive. And then to justify his opinions he posts AI content with lots of dubious bullet points and unsubstantiated claims.

I don't mind debating with a human being, but debating with him is debating with an AI bot. He consistently uses that method to respond.

I apologize for getting frustrated, but it's very frustrating and hard not to show it. If his conclusions were based on more than just a 10 minute test, or just weighing a tire, I would appreciate his contributions much more. I'm not the only one who sees what he's doing and gets frustrated by it.

His AI bot actually claims a short drive provides useful data when that just isn't the case. His AI bot claims ABRP is useful input for determining efficiency when is simply not the case. I can continue to refute and debate all the bogus AI bullet points, but it is frustrating to do that. So I won't.

Thanks for your kind words, @mkhuffman.

I haven't engaged with the substance of the arguments (on either side) at this time. The exact R2 mileage/efficiency/range aren't deal-makers or deal-killers for me. I agree that incomplete data, or data limited to a narrow range of circumstances, are much less reliable than what will emerge later.

What I engaged with was the name-calling. All of us are vulnerable to engaging in name-calling. But, in my experience, name-calling eliminates honest discussion -- usually starting with the most capable discussants, who have the highest number of other ways to spend their time.

Any sufficiently opinionated person can be mistaken for a bot. My ability to detect bots isn't very good. I'm not sure if any of us is that good at telling humans from bots anymore.

We can say our truth, with dignity and without excessive repetition.

Healthy communities yield the best discussions and insights. My concern was to preserve the health of the rivianforums.com community if possible. I believe that most of us got back to honest discussion, at least for now. Thank you all for that!

I'm interested in the efficiency at speeds of 35 to 50 mph, since that's the majority of my driving, although I understand that efficiency at highway speeds is of interest since that will determine how often you need to stop to charge on longer trips.

I don't expect the R2 to be great at highway speeds, given it's boxy shape, but I wonder how it compares to my EV6 AWD at lower speeds. In the warmer months the EV6
averages around 4.4 m/kwh, and even 5.0 when I'm driving in areas that are relatively flat. I haven't heard any numbers that high for the R2, but I'm not sure why not, since the new Maximus motors are supposed to be pretty efficient,, and the boxy shape shouldn't hurt too much at 40mph.
