The developer FAQ explicitly says split-screen is unsupported, and the supplied developer interview explains that decision. Campaign, Arcade events and Scenarios can run offline, but those solo modes do not turn one machine into a two-player race.

Star Wars Galactic Racer local multiplayer: the answer

Offline play answers a different question
The FAQ permits offline Campaign, Arcade events and Scenarios. You need to go online for patches and connected features, including multiplayer and Arcade friend leaderboards. PC also needs a connection on first launch for authentication.
That distinction matters when planning to play in a room without an internet connection. You can use the documented solo modes after the relevant setup, but offline availability is not evidence of couch racing or a local network lobby. A separate LAN mode is Not confirmed (待确认) by the supplied material.
What friends can use instead
The documented multiplayer alternative is online racing, including Quick Race and Multiplayer Tour for speeders, plus the corresponding podracer modes. The FAQ describes PC-to-console crossplay, enabled by default and optionally disabled. Separate participants should plan around those online features rather than connecting a second controller and expecting a split view.
Online parties support up to three players in the launch FAQ. The planned increase to six is an update intention whose live availability is Not confirmed (待确认) here. Race limits of twelve for speeders and eight for podracers are different from the number of people you can group together as a party.
Deciding what a shared-device session means
If two people each need control of a racer at the same time on one machine, the confirmed lack of split-screen rules out that setup. Adding a second controller does not create a mode absent from the developer FAQ. Offline availability only answers whether certain solo modes need a connection. It does not answer how many local players a screen can host.
Alternating attempts is a practical household arrangement rather than a multiplayer feature. You can take turns in an available solo mode, but that is not a simultaneous head-to-head race. Keep that distinction clear when deciding whether the game meets a couch-racing requirement. The material does not show a built-in pass-and-play menu or local score-comparison system.
For simultaneous play, the confirmed alternative is online multiplayer on separate supported devices. The FAQ lists PS5, Xbox Series X|S and PC and confirms PC-to-console crossplay. It also limits launch parties to three players, so a race with twelve spaces is not a twelve-person invitation group. Local networking, shared licenses and private-room controls remain separate questions without confirmed workflows here.
Future local support remains unconfirmed
The interview attributes the choice to the developers’ performance, visual fidelity and immersion priorities. That is their explanation of the omission, not proof that split-screen is technically impossible on every machine. Neither that interview nor the supplied FAQ announces a future local mode.
A specific release date for couch multiplayer, a mod that adds it, and a platform exception are all Not confirmed (待确认). Do not treat an online party-size update as a local multiplayer roadmap. The split-screen page focuses on the display feature and the developer’s stated design trade-off.
