New R1S and R1T QUAD vs OLD QUAD

[100Million]

I was wondering what the difference was between these two? Is it just software or is it hardware or is it actual motors. Because I have a quad motor adventure. That I bought in 2024. But now it says the new one is 2.6 seconds for 0 to 60 and like 1100hp.

Can someone please explain the difference. Thank you

Wow, I forget some folks don't pay attention to these things.

In addition to all of the upgrades that came with Gen2 models, the most significant difference with new quad from old is that Rivian is now using their own motors and no longer using the Bosh motors. Yes, more power and torque!

Don’t pay attention and seem to not do some web searching.

Even the Rivian site notes the differences, from more powerful computing, to less wiring, aside from the new motors

Price : )

Some are just lazy

Lots of differences. Better to ask ChatGPT/CoPilot for the summary. I just did and it is quite good.

EDIT: Pasted below, hopefully it copies nice.


The differences between the first-generation Rivian quad-motor vehicles and the second-generation quad-motor models with over 1,000 horsepower are pretty dramatic—especially under the skin. Here's a breakdown of how Rivian evolved its flagship R1T and R1S platforms:


Powertrain & Performance

Feature	Gen 1 Quad-Motor	Gen 2 Quad-Motor (2025)
Motors	Bosch-supplied	Rivian-designed, in-house
Horsepower	835 hp	1,025 hp
Torque	908 lb-ft	1,198 lb-ft
0–60 mph	~3.1 sec	2.5–2.6 sec (with Launch Mode)
Quarter Mile	~11.8 sec	10.5 sec

• Gen 2 introduces Launch Mode, which optimizes suspension, battery, and traction control for maximum acceleration.
• Active torque vectoring and staggered tire setup (Michelin Pilot Sport S5) improve handling and grip.

Battery & Range

Feature	Gen 1	Gen 2
Battery Pack	Max Pack (~135 kWh usable)	Max Pack (~149 kWh usable)
Range	~314 miles	~355 miles (estimated)
Charging Speed	~200 kW peak	~220 kW peak

• Gen 2 uses a redesigned battery pack with improved thermal management and simplified architecture.

Software & Architecture

• Gen 1 relied on Bosch ECUs and more than a mile of wiring.
• Gen 2 slashes complexity with in-house zonal architecture, reducing ECUs from 17 to 7 and removing 1.6 miles of wiring.
• Enhanced infotainment, driver-assist tech, and one-pedal driving with three regen levels.

Interior & Trim

Feature	Gen 1	Gen 2
Trim Level	Adventure	Ascend (premium)
Materials	Vegan leather, basic audio	Upgraded vegan leather, premium audio, electrochromic glass roof
UI & Controls	Touchscreen-heavy	Improved UI, better climate controls, Dolby Atmos audio

🛞 Ride & Handling

• Gen 2 features recalibrated suspension, hydraulic roll control, and new dampers for smoother ride quality.
• Off-road modes like Rally and Drift offer tailored torque delivery and suspension articulation.

The Gen 2 Quad-Motor isn’t just a refresh—it’s a full-on reinvention. Rivian’s move to in-house motor design and software integration has unlocked supercar-level performance in an electric SUV or truck. If you’re into EVs that can both shred trails and smoke Lamborghinis at the drag strip, this one’s a beast.

I can tell you as someone who owned a Feb-23 QM R1S and changed to a 25 Tri-R1S it is a big change. Hardware, refinement, and lots of other things. Is it worth the money I can't make that call but I am happy I personally did it.

I want to know if those tires will fit on the old quad. I guess not.

Some AI copy/paste errors in there for sure, that Gen1 kWh is a "large." My 2022 Launch Edition quad charges over 200kW, pretty sure max I've seen was 224 and I went WOAH.

I can tell you as someone who took an overseas deployment just to save enough money for a TRUE Launch Edition Quad, I'm perfectly happy with my Gen1 and won't be "upgrading" to a Gen2, let alone this phony "R1 Quad Launch Edition."

I say we true Launch Edition owners rise up and stand against the usurping of the name! It's high time we claim our spot atop the Rivian horsepower thrown and show these youngins where the real power lies... In miles and miles of wiring! /s... (Or am I?)

I had a '22 T and traded it for a '25 tri, and I feel the same way. The T was almost the perfect car that I wished it was, but the new one is that car and more. The only thing I wish it had was the Meridian sound I had in my old one.

The rear size won’t fit but you can just use the 275/50/22 front size all around on the old quads. The new quad is a staggered setup with 305/45/22 in the rear.

I have heard people say that but to be honest my hearing isn't anywhere near as good as it used to be so I don't really notice the difference. I laughed when Kyle from Out of Spec said 'We blew out the subwoofer when we blasted it on high volume and that isn't acceptable'. When I am driving and I can hear someone else's music through my closed windows and usually theirs I just laugh at how ridiculous that is.

I'm running the up front tires as a square setup on my R1S Tri motor. They're awesome, no more tire spin unless I'm accelerating in a hard corner.

I got them off tirerack.

Looks like the 305's are available now too. Specs say you need a 9.5-11.5" wide rim, I think the normal sport 22's are 8.5

I'm sure pricing starts way over $100K as the Tri starts at $99K.

IMHO, There is just no way to justify that level of pricing until Rivian improves all the other consistent issues they still haven't addressed with QC, Deliveries, Communication, Buggy Software, etc.

On my "lesser G1 T", I've been lucky and issues are pretty well expected on Gen 1 products.

Now that we're Gen 2 with essentially Gen 2 motors (not Bosch) all of this nonsense should have been solved by now. Still seeing reports of major issues ar Gen 2 deliveries or shortly after, not ok at $100K+ Gen 2 products. Hoping for the best for this "launch".

The Gen 2 Rivians have better features to be sure,. So may Gen 3 Rivians have better features than Gen 2s, and Gen 4s may be better still than Gen 3s, and so on. C'est la vie in the tech world. The upgrading battle just because better is one I never could win or care to engage in. No, thanks. I like my R1SQ Gen 1 a hell of a lot and will enjoy it for years to come.
