Be cautious with the absolute values. ABRP assumes 71 kWh for the LR battery (51 for SR). 78+ is the capacity Tesla has tested. 75 kWh is imo a more realistic number.

Model 3 LR range - anyone check it out?

I agree. According to the previous reported cell numbers the big pack contains 4416 and the small pack 2976 cells. So the capacity ratio is 1.48. If we assume they have the same relative buffer size the usable capacity should have the same ratio.
If the small pack is indeed 51 kWh the large pack should be around 75 kWh.
Not sure if this is already said. But based on EPA data M3 SR will have about the same highwayrange as a MX 75D. 10% less than MS 75D. Check Troys post:
[Spoiler Alert + Mild Speculation] Tesla has created a monster!
I think you are confusing ABRP pack sizes with actual pack sizes:
ABRP = 51 kWh and 71 kWh
Actual = ~50kwH and ~75-78kWh
ABRP pack size estimates were made before actual Model 3 data was available, and apparently have not been updated to actual pack sizes. But not to worry, it makes little to no difference in ABRP trip planning (since only ~60-70% of the pack size difference affects things).

Sorry, I did not have the time to understand the whole thread yet, but let me just clarify that ABRP does in fact assume 71 kWh usable (75 kWh battery pack with 4 kWh bricking protection) for the M3LR.
The EPA docs contain quite a few questionable numbers so if that is the only source of information, I would be very cautious to change the current assumption. What ABRP needs is a Model 3 owner who keeps ABRP running while being logged in to MyTesla in ABRP so that we can log some numbers
I have a MS-60 that shows 208 miles when fully charged. I live in North Carolina and have taken trips to Miami Beach, Central Georgia, Ohio, and Boston.
I can only recall 3 times that I was ready to leave from charging before the car was charged enough continue. Usually I'm at a restaurant or talking to another Tesla owner.
There were only two times I had to choose a longer route to use a supercharger adding an hour to a 14 hour trip. When we are at events in the middle of nowhere I have always been able to plug into a 15 amp outlet at the hotel to add 40 miles overnight to meet our needs.
We have nearly 20,000 miles on her and will be completely comfortable selling our last ICE car when we get our M3. We have no worries about long trips in a Tesla.

Don't know if this has been posted elsewhere, but I found this youtube video of a 14 miles model 3 trip to a Supercharger San Mateo Ca - Bridgepoint Pway.
Although this video is about charging speed, I found the following interesting info on M3-LRs energy consumption:
At 0:14 he starts with 94 mi charge at I280, crossing the 35 at 70 mph (58F)
At 1:10 he's at the supercharger with 80 mi charge
According to Google maps and ABRP he drove 14.1 miles.
So it seems rated and real world miles are pretty much the same under these conditions.
310 EPA range could also be real range!
(driving at 70 mph hwy combined with city at 58 F)

Isn't that stretch substantially downhill? And, typically downwind, as well? If so, that would make a huge difference in efficiency, easily enough to offset 70 mph travel.

But he has the 19 inch Sport wheels; not 18 inch aero according to the Model 3 Delivery Paperwork video.

Has anyone credibly sorted out the adverse highway range effect of 19"s vs 18"s (w Aero cover)? (I'm assuming 19" vs 18" w/o aero cover is negligible)?
(Dammit Jim, I'm an accountant not an engineer!)
well, the EPA did since there's different numbers for those configurations, and as rumored from long ago, it was a ballpark 10% figure at highway speeds. This reflected not just the 19 vs 18 and addition of aero covers but the change to a low rolling resistance tire.

I agree, figure about 10% with the aero covers and the 18"LRR tires. The 19" wheels use "performance" tires and that contributes to the loss in range. I figure I can get maybe 240 mile max. range with the SR battery, 18" wheels with aero covers and stock LRR tires, and driving conservatively (65 mph and regen braking).
I have a Prius Plug In and have learned how to drive an EV to maximize range. You need to learn a new driving protocol if you want to achieve the advertised range of an EV. You can drive an EV like you would an ICE (floorboard it on acceleration, apply brakes two car lengths from stopsign, and drive 75/80 on the highway), but you will be disappointed in the range.

Yes, six years and counting in my 2012 LEAF (hit 70k yesterday) has enabled me to appreciate how to get max range from an EV. I'm planning on the M3LR, and have been wrestling with whether to get the 19" wheels because they're pretty, or go with the 18" wheels (without the covers, which I find unattractive). I hadn't realized until now that there's a 10% range penalty with the 19s, vs the covered 18s. I'd cover the 18s for my road trips. Perhaps I've found my tie-breaker decision...range maximization! So, thank you for the comments. 10% is a big deal to me on road trips in particular. Local driving, LR is an extravagance and I can yank the aero covers for local use...looks to be a quick process. One quick question re the tire differences: should I expect the ride on the LRR 18s to be louder? I can't stand road noise and typically spend whatever I need to in order to get the quietest tire I can find. Thank you.

Using the 18" rims without the covers for local driving and with covers for long distance driving is a terrific strategy. I use Michelin LRR Energy Savers tires (they were not OEM) on my Prius and my range went up and tire noise went down compared to OEM. Model 3 uses Michelin Primacy LRR tires for the 18" (uses Continental performance tires for the 19"). The Primacy tire is a newer design than the Energy Savers. Here is what TireRack.com says about the Primacy tire:
The Michelin Primacy MXM4 did a good job softening the sharp edge of abrupt impacts, feeling taut but not harsh. The Goodyear Assurance ComforTred Touring was right behind, feeling almost as refined and controlled as the Primacy MXM4. The Continental ContiProContact and Bridgestone Turanza Serenity followed, both feeling a little less supple than the Primacy MXM4, allowing a bit more of the road's imperfections to be felt by the driver. The Primacy MXM4 also delivered the quietest ride of the group, producing minimal tread noise and only a modest boom when encountering abrupt impacts.
The Primacy tire had the best LRR and efficiency of the tires tested.
In my opinion you will be much happier with the 18" wheels compared to the 19" wheels given your criteria. I am choosing the 18" wheels with stock tires for my model 3 with enthusiasm. Again, I think I can beat the 220 mile range of the SR battery with a little planning and smart EV driving.
