? Official EPA Range and MPGe Numbers for R1T & R1S

[n8dgr8]

Replacing 21s is going to be an awful experience. I would stick with 20s. If you don't like the range. When they are worn out, find something with less aggressive tread.

So just so I’m clear. That’s only 268 miles on range on a fully charged battery using the off road 20’’ tires? Is that correct?

and only 241 miles of range charged at 90%?


is this correct?

I’ll fix this for you:
So just so I’m clear. Rivian’s number came in 5% HIGHER than the target range of 300 miles?

and if I decide to use AT tires instead range is still 90-95% of the original target range?

This is great news.

I don’t understand the motortrend review showed a Rivian with 20 inch wheels which had a 301 mile range in trip mode.
We’re looking at 270 miles. What happened?

And I'm configured back to the 22's. These are EPA numbers, so should be in line with other manufactures, Tesla included. The EPA rules are what they are as others have argued ad nauseam.

So an honest question. If this is suppose to be an off road truck and the 20’’ tires are for off roading, and we know that 22’’ tires ride worse and are for street driving… why would anybody get the 22’’ tires for an off reading type of truck?

Wait… 90-95%? Would t that be 85%-90%?

Question - Does the EPA rating have to be based on how that model is spec'd? In other words, do we know if the 10-15% "range hit" on 20s is based on AT or AS tires? Maybe a 10% hit on AS and 15% hit on AT?

Like other I'm going to need to re-think the 20s

lots of posts on this, but Tesla does a 5 cycle test with the EPA that (in theory) should be more accurate. Because the EPA is a mixed cycle (even their highway test), it doesn't equate to going say... 70mph constantly. So Tesla's are known not to high their rated "range" on the highway. Other manufacturers use a less expensive and accurate test that has a fudge factor applied to it, and then they can also choose to de-rate the range. FOr example, Ford lowered the range from what the EPA would say on the Mach e. The Taycan is famous for this. EPA range of like 207 miles or something, but people routinely get 270 miles on the highwayl.

Rivian is also using the 5 cycle test.
And it appears the nominal battery capacity is 144 kWh (400V * 360Ah)
Official classification is "Part time 4-Wheel Drive".
No voluntary reduction of range is listed.

Curious that the R1S is slightly less efficient than the R1T (assuming I'm reading the kWh/mi figures correctly). That must mean the battery pack in the R1S is slightly larger than what's in the truck.

RJ has said the aerodynamics of the R1S were better than the truck, hence a better range by a little.

Too bad there is such a drop with the 20s. But for 95% of our driving, it is perfectly fine. However having a range of 260-280mi (with 20s) and then towing on top of that (they warned up to 50% drop in range)..... That's 130-140mi towing range. Anyone planning to tow may want to stick with Max Packs only!

With battery degradation and real world driving conditions, we could be looking at a reduced range down to 200 miles. So that’s only 100 miles each and arriving back at a scary zero on the gauge. Dam.

Because like most American's who buy trucks, off-road vehicles, Range Rovers, etc....95% never leave the pavement.

 

[TessP100D]

Based on the city vs. hwy table that @kanundrum just posted, it looks like the R1S does better on the highway, and the R1T does better in the city. And the official EPA numbers are based on 55% city and 45% hwy. So maybe that's the reason?

I was just told by Tesla that city stop and go uses way more energy than a constant freeway driving. I have found this to be true as well.

 

[jagged]

I'm going to assume this is w/out the off-road upgrade package (tow hooks and additional reinforced underbody shielding)

I get that and agree. It’s just i see a lot of buyers here who talk about off roading. Max pack required in my opinion.

He must have been confused. According to the EPA, the R1S is less efficient than the R1T.

This was exactly what I was expecting, so I don’t see why some people seem so surprised. This is a great range for the wheel/tire combinations. I’m sticking with my 20 inch wheels with the ATs, and if I ever need more range for some reason, that sounds like two wheel mode will help with some range. I bet you with software updates and calibrations will have increased range over the life of the car as well.

I could always buy a second set of tires with less aggressive treads on them, it might even beat the 21 or 22 inch ones
