With more and more information beginning to slowly trickle out about what the R2 will be packing, we’ve finally got the details on the R2’s next-gen infotainment chipset. Just like the Gen 2 R1 series vehicles, the R2’s chipset will also be responsible for all the AI capabilities - which includes addressing Rivian’s autonomy ambitions.
Infotainment on Gen 1 and Gen 2
Rivian’s Gen 1 processor had three ECUs on board and was relatively capable—but hamstrung in its own ways. It couldn’t process high-resolution imagery and was only as capable as the Mobileye EyeQ4 that was on board. Many users also noted the distinct lag that occasionally happened in the infotainment, especially when rapidly scrolling the map with the satellite view mode.
Gen 2, on the other hand, consolidates those three original ECUs down to one and packs 3.3x the neural processing power on board—alongside 4K image processing. That, along with an effective, smooth, and precise infotainment system, made Gen 2’s XMM2 infotainment chipset a highlight. Now, the R2’s infotainment unit is going to take it to another level.
More Power, More Compact
The R2 and the R3 will feature the XMM3 chipset, which consolidates chips—including memory and power chips—at a 4:1 ratio. This unit will also have 2.4x the compute power of the current Gen 2 XMM2 unit.
This sparks a pretty interesting question—what about Autonomy? Rivian has said they’ve gained a renewed interest in addressing vehicle autonomy. Rivian plans to launch “eyes-off” highway autonomy in 2026 and hands-free highway assist will launch on the Gen 2 in just a couple of weeks with software update 2025.06.
That begs the question, will Rivian require the XMM3 chipset for future autonomy goals such as eyes-off or future Platform+ features?
What About R1S & R1T?
Just like the improvements to the drive units that are coming to the R2, these infotainment improvements will likely eventually make their way over to R1S and R1T as well. Given that Rivian just recently finished retooling their production lines for R1 Gen 2 vehicles, we’d expect them to arrive after the launch of the R2.
With that said, Gen 2.5 or Gen 3, whichever Rivian decides to call it, it’s likely still a couple of years away, but expect it to take advantage of a lot of newer R2 components.

Rivian fans have been eagerly awaiting official specifications for the upcoming R2, and a newly published EPA certification application appears to have finally delivered just that.
The comprehensive documents, filed by Rivian for the 2027 model year, provide our first detailed look at the R2's battery capacity, charging capabilities, motor output, and expected range. Here is a breakdown of the key takeaways from the R2's EPA filing.
Battery Capacity and NACS Charging
According to the filing, the R2 will feature an 86.8 kWh Large Pack battery. This is notably smaller than the packs in the flagship R1 vehicles, aligning perfectly with the R2's smaller footprint and more affordable price target. The battery pack weighs in at 541 kilograms (roughly 1,192 pounds) and operates at a nominal voltage of 353 volts.
When it comes to charging, the documents confirm that the R2 will natively feature a North American Charging Standard (NACS) port located on the rear driver's side of the vehicle. For home charging, the R2 supports an 11.5-kW onboard charger capable of drawing 48 amps on a 240-volt circuit. When out on the road, the SUV supports DC Fast Charging at up to 210 kW.
Dual-Motor Power and Impressive Weight
The certification documents specifically detail the Performance AWD dual-motor variant of the R2. This powertrain utilizes two AC Permanent Magnet motors: the front motor produces 219 kW, and the rear motor outputs 270 kW, resulting in a combined maximum output of 489 kW, or roughly 656 horsepower.
Perhaps the most impressive specification in the entire filing is the R2’s weight. The R2 Performance AWD equipped with 21-inch wheels has a curb weight of just 4,998 pounds. The model, equipped with 20-inch All-Terrain tires, weighs only slightly more, at 5,016 pounds. Keeping the curb weight under 5,000 pounds plays a huge role a big achievement for a dual-motor electric SUV and plays a huge role in the vehicle's overall efficiency.
The R2 comes in just 500lbs heavier than the Model Y Performance, 600lbs heavier than the ICE Porsche Macan GTS, and about 1,000lbs heavier than its closest hybrid equivalent, the Toyota RAV4, which is quite impressive for such a large and capable vehicle.
Range and Efficiency Estimates
While the EPA has not yet published the final consumer-facing range stickers, the raw testing data included in the filing gives us a very clear picture of what to expect.
R2 Performance AWD
Unadjusted City Range
Unadjusted Highway Range
Expected Combined Range (0.7 Derating)
21-Inch Wheels
487.4 miles (155.7 MPGe)
410.8 miles (131.2 MPGe)
~317 miles
20-Inch All-Terrain Tires
478.9 miles
392.1 miles
~308 miles
During the unadjusted urban driving cycles (UDDS), the R2 equipped with 21-inch wheels achieved a staggering 487.4 miles of range with an efficiency rating of 155.7 MPGe. On the unadjusted highway cycle, it achieved 410.8 miles at 131.2 MPGe. Applying the EPA's standard 0.7 derating factor to these unadjusted numbers results in an expected real-world combined range of approximately 317 miles for the 21-inch wheel configuration.
The 20-inch All-Terrain variant takes a slight efficiency hit due to the more aggressive tread pattern. In the same unadjusted tests, the All-Terrain model achieved 478.9 miles in the city and 392.1 miles on the highway. Applying the same derating factor puts the expected combined range for the All-Terrain model at roughly 308 miles.
A New Heat Pump
Finally, the documents reveal that the R2 will utilize a brand-new, proprietary heat pump design. Rivian notes that this new heat pump integrates valves, sensors, heat exchangers, and a refrigerant bottle into a single bundle to save weight and space. The filing explicitly states that this system will dramatically improve real-world range in cold weather environments compared to vehicles equipped with traditional heating systems.
Rivian’s R2 is quickly becoming the ultimate scavenger hunt for electric vehicle enthusiasts. As the company prepares for its first deliveries later this spring, fans are uncovering a series of hidden design details — or easter eggs — that show just how much personality the R2 design team has baked into the SUV.
The latest discovery comes from an R2 Block Party event in Venice, California. A video shared by Douglas Izzo (@douglasizzo) on X reveals a tiny vehicle silhouette etched directly into the driver’s side corner of the taillight. The hidden graphic features a small outline of the R2 itself right next to a miniature Rivian logo. Interestingly, the detail is exclusive to the driver’s side, leaving the passenger side taillight clean. Izzo noted that the secret was pointed out to him by Jack, a member of the R2 design team.

This isn't the first time Rivian has hidden fun details in its mass-market SUV. Last month at SXSW 2026, we saw a solvable maze printed on the inside of the charging port door. Other eagle-eyed fans have spotted a Gear Guard Gary decal on the windshield frit band and a small rock climber graphic tucked away on one of the rear windows.

These details might seem minor, but they go a long way in building brand loyalty. It shows that Rivian isn't just focused on utility; they want the car to feel special to the people who buy it. Rivian is currently taking the R2 on a cross-country viewing trip, giving reservation holders and fans plenty of chances to hunt for even more secrets before the order configurator officially opens.
Delivery Timeline and Trims
As fans enjoy these easter eggs, the real excitement is the approaching delivery timeline. The R2 Performance trim, starting at $57,990, will be the first model off the production line. This dual-motor AWD flagship offers a 3.6-second 0–60 mph time and 330 miles of range.
R2 Standard Long Range ($48,490): Slated for early 2027.
R2 Standard ($45,000): The base model is currently expected in late 2027.
The R2 is a massive play for Rivian, designed to bring its "electric adventure" brand to a much wider audience. By including these quirky design touches, Rivian is making sure the R2 stands out in a crowded market filled with more sterile competitors.
Whether it's a maze in the charge port or a silhouette in the taillight, these details make the R2 feel like it was designed by people who actually love cars. As the R2 makes its way through more cities over the coming weeks, it's likely that we haven't seen the last of these hidden gems.
