Recent EPA certification filings, initially discovered and published by users on the Rivian Forums, confirm the battery and range specifications for the 2027 Rivian R2. The official documents detail an 86.8 kWh battery pack that exceeds initial manufacturer estimates for the dual-motor platform.
Highlights
- Usable battery capacity is rated at 86.8 kWh, supporting a peak DC fast charging rate of 210 kW.
- Models equipped with 21-inch all-season tires achieve an EPA-rated range of 335 miles.
- The 20-inch all-terrain tire configuration delivers a certified range of 314 miles.
- Vehicle curb weight is tested at 5,250 lbs, with a gross vehicle weight rating (GVWR) of 6,173 lbs.
Addressing the Mid-Size EV Market
As automakers scale electric vehicle production, balancing battery size with curb weight remains a critical engineering challenge. The mid-size electric SUV segment requires vehicles to maintain reliable range metrics without inflating pack costs or mass.
By utilizing an 86.8 kWh pack to surpass 300 miles of range, Rivian demonstrates baseline platform efficiency. Furthermore, this efficiency is vital as consumers demand longer travel distances between charging stops.
Technical Specifications
The EPA filings verify several key hardware and software updates for the upcoming Rivian R2 platform. Engineers have integrated a redesigned thermal management system to handle the new electrical architecture.
Specifically, the updated heat pump is repositioned to minimize vibration and lower cabin noise. Additionally, the latest vehicle software suite introduces built-in battery health monitoring for owners.
The published data outlines several specific performance capabilities:
- Nominal Capacity: The large battery pack provides 260.8 Ah based on a constant current C/3 discharge rate.
- Charging Architecture: The system manages thermal loads to support 210 kW peak DC fast charging.
- Payload Rating: The 6,173-pound GVWR allows for approximately 1,175 pounds of total payload capacity.
- Lifecycle Planning: The system includes planned integration for second-life battery disposal and recycling.
