If the city roads you frequently drive are in poor condition, that could be contributing to lower efficiency. Pitting, cracks, potholes, uneven pavement, etc. all have an impact, literally.
Edit: Seeing as you are in CA, have no worry that the poor road conditions are being addressed by state...
There are several small factors here, including BMS accuracy, odometer/GPS error, and the usable-capacity assumption, and they mostly wash out.
Bottom line: in the 65.7 mph test over nearly 4 hours, the vehicle was a 250-mile range EV.
Depending on the assumptions, you get about 253 miles with...
I guess I interpreted it slightly differently:
Real time - 3 hours 51 min
Real distance - 253 miles
Real kWh consumed - 91.43 kWh (256/2.8)
Real efficiency - 2.77 MPK (253 / 91.43)
Real speed - 65.7 mph (253 / 3.85)
Real range at 88 kWh and 65.7 mph - 243.8 miles (88 x 2.77)
Real 80% range -...
I get 253 miles divided by 3:51 (253/3.85) = 65.7 mph
15 minutes too slow for 70 mph…
Also, the implied 88 kWh range is 246 miles.
80% is 197 miles (~5 less than you have)
65 mph range is 200 miles and you can adjust speed up/down 10 mph to get 10% less/more range…simple rule
Have tires broken in? Do you see increased efficiency as a result? I found break-in occurred between 500-800 miles (R1S)? What’s your average efficiency so far?
A couple years ago it was 200k, so it had to have grown since then, right?
How popular is the R2 going to be? It seems like it fits most people, so it could easily become a strong competitor to Model Y (>1M / year). Let’s say 500k R2 sales per year by 2029
2026 - 40k
2027 - 125k
2028 - 250k...
We should have a better idea in ~8 to 12 months or so...a few things are apparent/standout:
1 - Demand is relatively high, with somewhere between 250k-500k total reservations.
2 - Supply will be extremely limited in 2026 and will likely continue in 2027-2028.
3 - Rivian financial position...
The elephant in the room is that all this data is extremely high-biased, once we get into the cold season the numbers will drop significantly. So get out there and collect the high-biased data while you still can!
Max R2 range using 80% of battery:
224 miles @56.2 mph
208 miles @61 mph
192 miles @67 mph
175 miles @72 mph
160 miles @76 mph
2016 Model S range using 80%
168 miles @75 mph
EV Database: 75D at roughly 215 miles at a constant 70 mph in mild weather, based on about 72.5 kWh usable when new.
Specifically I’m saying that the R2 is range-limited to ~200 miles or so. It’s EPA range is stated at 330 miles!
Likewise, the 2016 Tesla Model S (75D) was also range limited to ~200 miles. Long term its efficiency is ~3.2 MPK. 3.2 x 75 = 240 miles.
So on average the R2 range is equivalent...
