A next-generation heat pump on a shared coolant loop.

## What it is

A next-generation heat pump is described on a shared coolant loop. The pack's coolant is described as crossing once. Brake cooling is tied to the barge boards, and an active hood vent is described for heat leaving the system.

Figures below come from Tesla posts or from engineers speaking to outlets. Where sources disagree, the spec sheet says so.
