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

[tivoboy]

Great news, OoS just did very short but well controlled 50, 60, 70, 80mph tests vs a Model Y.

Worth noting - the 10% challenges show a much larger difference than the side-by-side runs. I think it's pretty safe to say the R2 is 20-25% less efficient than the Model Y (Performance) at any given speed. I don't see a meaningful/clear deviation as speeds increase.

One thing to note - the R2 was run on *FRESH* tires. Like ~0 miles. For the side-by-side it got better efficiency despite colder temperatures. I am thinking combination of brand new tires and wet road really did a 1-2 punch on efficiency in the 10% challenge test.

I thought when they started all of this they said the tires has ~ 1017 miles on them. Normal, IL to east or Raleigh, NC is ~ at least 850 miles?

You are right. The R2 has 1,000+ miles on it n

The R2 came on 20" wheels.

I don't actually know when they swapped them. Perhaps it was at the factory?

Yes at the factory. Jose had the 20s in the back.

In the first video they say “these tires should be pretty well broken in” I think he said soaked.

Thanks to all the debaters…and detractors. I’ve added the Out of Spec findings to the top of my original post, and they happen to align closely with my earlier analysis. I understand some people still aren’t satisfied with the OOS results, so I’d encourage them to collect their own data and see whether it produces a different outcome.

That’s the beauty of science: test it, compare results, and follow the evidence.
