Where are all the R1S in R1 Shop?

Since the AC compressor was moved, it seems likely there are other significant changes under the hood since they probably had to re-engineer all of the paths for that, so it's clearly not just electrical changes.

Do you think changes to the AC compressor location and firewall/bulkhead design suggest that the interior ventilation design has been updated as well?

Do you think the changes to the AC compressor location and firewall/bulkhead design could indicative of an updated interior ventilation design?

I would not expect the physical arrangement of the interior stuff to change, but certainly the overall effectiveness in the refresh should get better.

This is the full text under the heat pump section that's pretty detailed about what they changed.

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. In addition, R1 heat pump has several other upgrades, including:
• Improved cabin cooling during hot ambient.
• Improved NVH due to relocated compressor.
• Improved cold ambient performance with a HV coolant heater.

@Dark-Fx, thank you for sharing. That’s a ton of good information and sleuthing.

I expect to see the auto websites referring to more information gleaned from leaks and rumors on the rivianforums website in the coming days.
