More power & faster in All Purpose than Sport Mode - confirmed with data / dragy

[bmedfo1]

OP, could you please give us more around suspension setting, ride height, SOC, battery temps maybe? Would be appreciated.

Suspension on Firm, low ride hight for both sport and AP pulls. Done back to back after battery temp was 80 F. 90+ Soc.

I repeat the experiment dozens of times mixing a few of these up but always the same result. Full power in AP, limited power from sport (over 40 Mph)

As soon as I get the update I will test again to see if anything changes.

Out of curiosity, what tires is your truck configured (by Rivian) for?

I do wonder if part of their calibration is to limit power in certain circumstances... it'd make sense, wouldn't it? You wouldn't want to give the same power curve (in theory) to all-terrains as you would sport tires, for example.

What'd be really interesting is if you could find other RIvian's with different configurations and test those side by side with your findings.

Thanks for sharing the data!

The update notes, I noticed, stated improved acceleration response under Gen 2, not Gen 1 via Rivian Trackr.

I wonder if it has anything to do with power distribution? Does Sport do anything like bias to rear motors at speed, maybe reducing power to the front for better handling feel (i.e., it's not just about top speed)?

Dang. The original version of those notes showed acceleration adjustments for all. Curses! Give me full power or give me death!

My tire tread is cowering in my garage at the thought of all this aggressive driving. I thought we bought these vehicles so we could circle the Costco parking lot on Saturday afternoon looking for the perfect parking spot.

Are you saying we can have fun in them also? Hmmm, I’ll have to ask my wife if she needs anything at Costco.

Yes I noticed it was removed for Gen1.

I'm guessing (wild guess here) is directed to Performance Dual Motor.

It is well stated that the "Performance" upgrade is only applied on Sport mode for those trim levels, so probably they allowed the All-Purpose mode more power to make better use of the "performance" upgrade that people paid for.

Thanks a lot.
in case you are so inclined, it would be neat to know if full power is drawn at medium suspension height and moderate and/or soft damping.

Maybe I can play with this myself, but if you are doing pulls anyways…

Did your post Spark a good conversation? is so can you drop the link?

I can not believe this is not a huge discussion? Sometime I feel like im one of very few who purchased (at the time) the quickest pickup truck ever made for that reason.

We are all driving around in $100k supercar fast bada$$ offroad trucks and the big discussions are always about how to save $0.00001 per mile or how to get 1% further on a full charge even though we could just stop and charge a bit the hand full of time a year most of us drive over 300 miles. But I digress.

Hopefully more will chime in and maybe we Spark enough discussion that Rivian will let us use our extra 125 HP in sport.

I bought it because it was a rip-roaring super truck, and I didn't want the CT which I had ordered. Sadly it is significantly slower than my friend's CT and likely the new G2 quad might not beat it either. So the fact you get more power at higher speeds in AP just baffles and infuriates me at the same time.

I didn't buy a 7k pound truck with 800+ HP to drive it like a watt pinching miser. Or obsess over my efficiency. It was another reason I spent the money for Atmoic Wheels to save weight and went with tires other than the Michelin LTX or any variant thereof. I wanted more contact patch than they'd provide with their measly 7.8" tire width. I drive it in sport mode 99% of the time unless I am on a long highway trip. Now I need to reassess of maybe Sport mode to 60 and AP above that.

Why can't they just give us something like the Plaid mode like on my Plaid to give it max performance at all times and still keep AP mode and while at it, add Valet mode and a speed limiter so when my kids drive it, I can keep them from going crazy.

I assume you're talking about the Cyberbeast? Remember, Tesla seems to have benchmarked the CT specs fairly specifically against equivalent Gen1 R1T trims, so it makes perfect sense that the CT comes out on top. From what we've seen of the Gen2 QM, Rivian's done the same against the CT, so now we're in tick tock arms race for 0-60 and quarter mile.

Rivian and Tesla didn't build their Tri/Quad specs for that either, so I think you're fully justified to want and use all the power and speed they advertise. With that said, we are talking EVs here, and I think even Hummer EV buyers just need to accept that they'll be playing in a sandbox predominantly focused on range/mileage. When we finally get ~500 true miles per charge, nobody will care about it, but while a 420mi vehicle might only get 100mi while towing, or 230 miles in the cold, it's going to be on people's minds.

The official notes from Rivian still have the line for Gen 1, but it says:

which is clearly a mistake.

In the 0-60 run, it isn't even remotely close with his CT vs my quad. He pulls me by a lot and keeps pulling even more at higher speeds. Which is significant as the trucks are fairly close in hp/tq but the R1T weighs a bit more. He has at least 10 mph more on the top speed limiter. I should try a run in AP from 60-100 to see if any closer.

As we all know to go from 3 seconds 0-60, to mid 2's that is a huge improvement. Much greater than lets say going from 4 seconds to 3.5 0-60. I just hate how much the R1T flattens out from about 50-60 mph and up. It just reminds me of my old Model 3 and S. Great numbers cars to 60 but definitely fall off after that. My Plaid was the first Tesla that wasn't just a 0-60's car. My S Long Range never met its claimed 0-60 times and my R1T would beat it, but it was very good 60-130. My Highland 3 Performance is quicker than my R1T to 60, but I will just leave it and hide from 50-60 mph and up.

If the R1T would keep pulling better from about 50-60, I probably never ask for more. If I did, the Tri wouldn't do it for me. I'd have to go with the quad. Sadly, I just don't see the value there for the price of admission.

I do get your point about the Watt pinchers. Unfortunately, Rivian is already in the hole there for road tripping or towing more than a charge's worth by the 400V architecture, and they don't even max out what they have there. If I am spending 60k+ on a truck, a few extra dollars a month on electricity is nothing compared to what I spend on tires, which still pales compared to the cost of the vehicle. We need faster and more convenient charging, than we need more range for most people. Then, we could reduce pack size and have better performance and efficiency. I didn't see much value in the max pack. It's a lot more weight to carry around when I'd never need the extra 20 miles of range I might get vs my large pack.

I enjoy this thread much more than how to eke out .01111111 Wh/mi because I upped my tire pressure by .25 psi. Key to max range on the somewhat aerodynamic brick the R1 is, would be to not exceed about 40 mph so aero drag isn't a big issue.

My truck has the 20 rims with 34" AT. This would certainly make sense for Rivian to do to manage traction and posibly even to compensate for the ~2-3% smaller diameter of the other wheel setup. However I would think this would no longer apply after say 65mph where we are still seeing reduced power.
