First long highway trip with new R1S, from Bellevue WA to White Rock, Canada and return. Temperatues were cool, 45-50 degrees F. Blowers on low with heat set at 69 internally. Battery charged to 100%, with only 3-5 charging cycles on this battery pack that has about 600 miles on it.

Total Distance Travelled: 242.8 Miles
Average Speed: 50 mph (note that cruise control was set to 65 for both directions, MPH average lowered from in town travel at destination that was less than 5 miles)
Duration: 4 hours, 51 mins
Efficiency: 2.23 mi/kWh
Total Energy: 109.1 KWh

When I parked back at home I had 13% remaining, calculated to be 42 miles

Efficiency lower than I would have thought given your average speed and fairly low HVAC needs. Was it windy do you remember?

Efficiency lower than I would have thought

285 miles range on 20's is just about exactly what Rivian advertises.

 

[BellevueMtt]

No real wind, and the tires were ATs as the commenter above pointed out.

I was looking at the 2.23mi/kWh figure tbh

Yeah not great considering that your CC was only at 65. I don't think I'll be able to bring myself to do that. At 72 mph, which is the best I can do, I would therefore expect 285*65^2/72^2 = 230 miles, under your conditions. That's actually not that bad, by then I'd want to stop anyway ...

I think the design point was 2.11 Mi/kWh (285 miles / 135 kWh) so this is slightly better. We were happy that the estimate made at the start of the trip matched the actuals with in 1-2 miles.

I am wondering if they will be able to get improvements with software updates over time. I have head that a lot of the Tesla efficiency is sw vs hw...

Probably won't move the needle much. Big vehicle, heavy with big cross-section. I'd wager on 5% max. Maybe if they develop an ultra-efficient mode range will go up a bit more but I would never use that.

Thank you for taking the time to record the data. I pre ordered mine almost two years ago now and haven't heard a word. I am disappointed with the results. I live in New England and based on this information winters would be tough on distance. to all of you with R!S cars pleas publish more "real" data like this. such a big help

I'm really curious to see how these do in colder weather. While 90-95% of my driving is close to home and shouldn't be an issue even if it is cold I'm wondering how often I might need to stop when making my trek to Lake Placid during the winter to see relatives. The Northern route 87 doesn't have a whole lot of chargers at the moment as they are renovating the pitstop areas.

Updated with full trip

Here is another run with colder temps, half of this run was at 40-43 degrees, half at 35-40 degrees. Highway travel, with reverse trip nearly the same route. Some traffic on return lowered the average speed, but was doing 72 on highway, and 50 on smaller state routes. Interior temp set at 70 degrees, heated seats running.

Summary - 254 miles, avg speed 46 mph, Driving time 5h 30m, Efficiency 2.1 mi/kWh. Total energy 121 kWh

What mode were you in (ie. conserve)?

Yes, conserve for 90% of the run. Perhaps 35 miles of "All Purpose".

AWD Tesla's are RWD unless drivers needs more acceleration or slip is detected. Even then, Tesla would have been 20% under rated range while the Rivian made its rated range.
