Rivian EPA document reveals upgrades in 2025 R1 vehicles

An EPA document about the 2025 Rivian R1 vehicles revealed some upgrades in the upcoming R1T and R1S. The two main Rivian R1 upgrades that excite customers are the heat pump and LFP battery.  

The EPA document is dated April 10, 2024. It covers the following Rivian vehicles: the Rivian R1T Dual Standard (20in), Rivian R1S Dual Standard (20in), Rivian R1T Dual Standard (22in), and the Rivian R1S Dual Standard (22in). 

Rivian’s LFP Battery Packs 

The 2025 Rivian R1 vehicles’ lithium-iron-phosphate (LFP) battery pack was one of the first upgrades that piqued customers’ interest. The 2025 Rivian R1 cars’ battery is expected to be more efficient as the battery pack size went from 105.9 kWh to 92.5 kWh. Rivian Forum members think the LFP standard range is software-locked to match non-LFP battery packs. 

In February 2024, Rivian rolled out two new range options for the R1T pickup truck and the R1S SUV. The EV company launched the Standard and Standard+ battery packs for R1 configurations. The Standard battery pack is estimated to deliver a range of 270 miles, while the Standard+ has a range estimate of 315 miles. 

The new battery packs use NCA (nickel-cobalt-aluminum) cell chemistry. Rivian has also announced plans to use LFP cells in the Standard battery pack in 2024. Rivian’s Standard and Standard+ battery packs will qualify for some of the Inflation Reduction Act’s (IRA) EV tax incentives. 


Rivian R1 Heat Pump 

Another big development in 2025 R1T and R1S vehicles is the heat pump. In March 2024, Teslarati reported that Rivian would use heat pumps in its new R2 platform. However, the EPA document shows that Rivian also installed a heat pump in the 2025 R1T and R1S. 

The EPA documents states: 

“Rivian has adopted a proprietary heat pump design to enhance the user experience and improve thermal efficiency.

  • A number of components, including valves, sensors, heat exchangers, and refrigerant bottle, are integrated into a single bundle for cost, mass, packaging, and assembly benefits. 
  • Real world range is expected to improve over R1 Launch vehicles (which is equipped with conventional AC system) when cabin reheat or heating is required (roughly below 20°C). 
  • Further range increase is possible via waste heat recovery from the ESS and powertrain when available.”

Rivian adds that the R1 heat pump includes several other upgrades, including improved cabin cooling during hot ambient, improved NVH due to relocated compressor, and improved cold ambient performance with a HV coolant heater.

Rivian shut down its Normal Factory in April to retool the R1 production line. The company expects its retooling plan to significantly reduce R1 production costs while increasing production rate. Rivian aims to deliver approximately 57,232 R1 EVs in 2024.
