Dual-Motor Max & Quad-Motor Large Pack have same highway efficiency - my real world test

[BrentInCO]

Last weekend, to perform an apples to apples comparison, my friend and I drove both of my R1S’s 300+ miles while staying within sight of each other (prohibiting drafting impact). Results are that the efficiency was exactly the same, at 2 miles/kwh. So, my Max pack should theoretically be able to go 20 more miles than my Large Pack, on road trips like this. Womp, womp. I just saved you from a 7 hour livestream. This warmish (temps in 30s to 50s, with some rain and headwinds) weather test yielded similar results as my first winter drive of just the Max pack on a route I’d driven my Large pack dozens of times. Dang. I’m torn on which to sell, but would probably lean toward selling my Max pack if I could come close to being made whole on the purchase, in the $90s.

Launch Edition Quad Large Pack 20”. Left Denver at 100% 310 miles of range in Conserve mode, and arrived at Rifle ChargePoint via interstate 70 with 78 or 25%, used 232 miles of range to go 192.8 miles (yes, 1/2 mile more than the other vehicle despite resetting tripometer at exact same point and driving the exact same route and having exact same tire pressure), 83% of rated range. 2.04 miles/kWh. Used 94 kWh, 2 hrs 59 minutes, 64 mph avg.

Max Pack Dual Motor 20”. Left Denver at 100% or 360 miles of range, and arrived with 113 or 31%, used 247 miles of range to go 192.3 miles, 78% of rated range. 2.0 miles per kWh. Used 96 kWh, 2 hrs 59 minutes, 64 mph avg.

Launch Edition charged to 224 miles or 71%, and arrived at Montrose ChargePoint with 95 or 30%, used 129 miles of range to go 114.7 actual driven miles, 89% of rated range. 2.06 miles per kWh, used 56 kWh, 1 hr 44 minutes, 66 mph avg.

Max pack charged to 252 or 69%, arrived at Montrose ChargePoint with 113 or 31%, used 139 miles of range to go 114.4 actual driven miles, 82% of rated range. 2.07 miles per kWh, used 55 kWh, 1 hr 44 minutes, 66 mph avg.

I had problems initiating charging via my new Bluedot app, and it only allows linking of one vehicle, can only initiate charging one at a time, and in Montrose the 2 chargers share the 200 kw, splitting power 120/80, so I couldn’t compare charging curve apples to apples, but I have no reason to think they are different.

Configurations are exactly the same other than battery size and # of motors. See my signature for details.

Great summary/comparison Brent. (And thanks for the non-YouTuber TLDR!) Makes me more happy with my LE Quad Large from a $/extra mile standpoint. I'll be interested to hear your off-roading capability comparison between the two once the snow melts in the high country. (If you keep the Max-Dual that long). Cheers and have a great summer.

Thank you for saving me from the YouTube hellhole. ?

I second looking forward to a direct comparison of trail capability between quad and dual motor.

This is the best comment I’ve read here in recent memory ?

BTW, (and I think you figured this out) while only 1 vehicle can be in your BlueDot account, you can charge any vehicle. You just have to initiate the charge from within the BlueDot app - and then it’s only one charging session at a time.

Great info. Thank you and your friend for taking the time to do the drive and report your data. I honestly figured Conserve Mode on the Quad would do pretty well based the EPA reports @Dark-Fx has linked.

As a dual max owner, all I have to say is "these go to 11."

Yes, I paid to charge the other one via the Bluedot physical debit card, so saved 20%, in order to have 2 vehicles charging at the same time, but it took minutes for each to successfully start charging. In Rifle, one of the four ChargePoints (all labeled as 200 kw) was maxing out at a very low kw, so I stopped, moved to the adjacent one, and it charged at a much higher rate. So, a lot of frustration, stops and starts, compared to the seamless experience of simply plugging in at a RAN or Tesla Supercharger . . . but I wanted to test out the Bluedot discounts, which make it comparatively super cheap.

Sorry, I don't understand. Would you please explain?

It's from "This is Spinal Tap" - a classic!

What about cabin temps and payload, eh?

All those factors were kept equal, of course. e.g. 73 degrees

 

[R1SFamilyGuy]

Honestly, though. Great work! Thanks to you both from the rest of us.

All said and done, the Quad conserve isn’t something one would do all the time. Given that, I see this as a “thumbs up” for Quad Conserve AND how the DMs operate but not necessarily a “thumbs down” for a Max pack.

I personally think the extra usable kwh will come in handy when camping and such non-range things.

Yes, that is why I'm torn, as I do a lot of camping, long drives. I just wish Rivian had a model with range like the Chevy EV trucks / SUVs are delivering . . . around 450 actual driven miles.

I really appreciate you doing this test. I was wondering if we were to get a second R1S (I'm not sure I'll be able to wait for our reserved R2 before we need another car) if getting a DM versus the Quad would give us more mileage per KWH. Apparently not!

Benefit of dual motors / max is largely to occur w/ City driving. I have ~5k miles on my 60 day old dual max, but due to a cold Spring in Denver, I don't feel I have enough data to say that matches my real world experience. It's been warmer over the last week, in the 70s, and I've been getting 2.5 mi/kwh on my daily work commute. At the moment, I don't know if that's better than my Quad or not. Could be, a little, as I don't use Conserve mode in the City. The lifetime efficiencies of both vehicles is around 2.28 mi / kwh thus far. My Quad has 30k miles and is 15 months old.
