70 mph Range Test - Tri / Max / Defenders / Conserve = 335 miles

I hear ya. I went from Utah to CA on Monday and it was the single worst drive I've had yet on my Gen 2 R1S, and I've done over a half-dozen 1200 to 3000 mile road trips since getting it, averaging anywhere from 2.5 to 2.8 mi/kwh per trip. I think the final round trip average this past weekend was 2.02 mi/kwh. Punctuated by massive wind noise. Yowza.

Yeah the wind noise in this $100k vehicle is kinda lame. As for the efficiency, my 15 min gauge was hitting 1.00 in some places lol. But wind and elevation it was to be expected.

@PaythePiper @TomServo2112 , not to hijack this thread, but some guy wrote really detailed guide on how to reduce the wind noise. it worked pretty well for me lol ?

So I did the 70 mph range test on conserve this morning. I ran from 100% down to 2% and got 324 miles => 330 miles. Adding in the buffer the total range is ~335.

• Michelin Defender tires on the Dune 275/60/R20s
• Max Pack
• On Conserve mode
• Efficiency 2.43 mi / kwh
• Temps ranged 55 - 73 degrees during the drive
• Elevation 50ft - 150ft
• Ran 2x separate speedometer apps to validate speed 71 mph on Rivian = 70 on both apps

Thank you for this. We have a ~350mile trip we take at least once a year to South Texas if not more and my biggest concern is range and having to charge frequently from my ABRP estimate trial runs. I have no clue what to expect real-world for efficiency in Texas heat on 20" ATs. This tells me we can probably stick to our normal 2 stops with minimal charging time. Granted, I have AT tires coming and you have those swapped out but even with a 10-15% efficiency penalty I think it would work.

woodcan,

Are you traveling south on I-35? There are numerous Tesla chargers between Dallas and San Antonio. Beyond San Antonio I do not know. There is a huge Buc-es in Temple.
