Sonic Racing: CrossWorlds was initially announced with a
teaser trailer at
The Game Awards 2024. The first gameplay trailer was shown during
Sony Interactive Entertainment's
State of Play on February 12, 2025, and a
closed beta test for the
PlayStation 5 version was held from February 21 to 23. This was followed by an open beta test for PlayStation 5,
Xbox Series X/S,
Nintendo Switch, and
Windows between August 29 and September 1. A single-player demo was released on September 17. In June 2025, leaked concept art and footage from an early build of the game revealed the existence of multiple guest characters from non-Sega franchises planned as downloadable content. The inclusion of guests was subsequently confirmed at
Summer Game Fest a few days later on June 6, along with the game's final release date of September 25, 2025. A
Nintendo Switch 2 version was also announced, and was released digitally on December 4, 2025, with a paid upgrade available for owners of the Nintendo Switch version that will carry over their progress. A physical Nintendo Switch 2 release followed on March 26, 2026. In addition to the standard edition of the game, a Digital Deluxe Edition provided three days of early access on all non-Nintendo platforms.
Limited Run Games produced a Collector's Edition of the game packaged with additional physical rewards, which was only available to order during June 2025.
Marketing During 2025, Sega promoted the game through a "Racing Around the World"
marketing campaign. A tie-in one-shot manga,
Sonic The Hedgehog — Blue Racer, was released for free via Sega's social media channels in July. A promotional short animated by Studio Giggex and SIMAGE Animation was released on August 29.
CrossWorlds includes in-game vehicle decals promoting several other external brands, such as
ASUS,
Beyblade, and
Hi-Chew. In October 2025, Sonic was added as an optional voice for the
Waze GPS software, along with
CrossWorlds themed icons.
IDW Publishing, the publisher of the
Sonic comic book series, also released a tie-in comic issue in March 2026. An
advertisement for
CrossWorlds, titled "Come Race on Our Level", received attention for
dimunitively comparing the game's dimension-hopping abilities and character customization to "[roaming] around on the open road" in "that kart racing game", heavily implied to be
Mario Kart World, whose
open world design received polarizing reception. The advertisement, which was based on a 1992
Sega Genesis TV commercial, drew comparisons to the
Nintendo-Sega console wars in the 1990s. ==Reception==
