Vehicle upgrades in Below Zero let you extend depth, improve hauling or movement, recharge a Prawn Suit in suitable heat, and defend a Seatruck from predators. The Vehicle Upgrade Console provides a dedicated place to craft modules when installed in a Moonpool, while some upgrades can also be made at a Fabricator or Modification Station. Several blueprints or upgrades are tied to specific exploration locations, so progression involves both building the vehicle and finding its modules.
