Momentum for Automobility: Unofficial Port

This project provides unofficial Fabric ports of Momentum for Automobility by milkucha for Minecraft Java 26.x versions.

Momentum changes the driving feel of Automobility: Unofficial Port with smoother handling, braking, coasting, steering, drift behavior, camera behavior, cruise control, and a compact speed HUD.

This is an optional addon, but when used in multiplayer it should be installed on both the client and the server so vehicle input and movement state stay in sync.

This is an unofficial fork/port. It is not affiliated with or endorsed by the upstream Momentum or Automobility maintainers unless stated otherwise by those maintainers. Please report issues for this port on this project's issue tracker, not on upstream support channels.

Features

• Reworked Automobility acceleration, coasting, braking, steering, and drift profiles
• Compact speed HUD while driving
• Cruise control on the C key with an in-HUD indicator
• Brake and drift key state sync on dedicated servers
• Optional YACL config screen support

Current Versions

Public builds are published per Minecraft target. Current targets include Minecraft Java 26.1.x and 26.2 on Fabric.

Requirements

• A matching Minecraft Java 26.x build
• Matching Automobility: Unofficial Port build
• Fabric Loader for that Minecraft version

Status

This port is beta. Core driving behavior, HUD rendering, cruise control, brake/drift input sync, and the optional config screen are working.

Testing has been done together with Automobility: Unofficial Port in singleplayer and multiplayer Fabric environments. This does not guarantee compatibility with every modpack, so please include logs and a full mod list when reporting issues.
