Vulcar Marine

Vulcar Marine is a marine engine manufacturer due to appear in Grand Theft Auto VI. It operates as a subsidiary of Vulcar and produces engines for boats and other watercraft. The company is listed as an active vehicle-parts business, though the publicly available material does not identify any particular engine model, product range or facility operated by Vulcar Marine.

Vulcar Marine's logo appears in Grand Theft Auto VI's second trailer. It is displayed on a banner at Brian's Boat Works & Marina, placing the brand among the marina's boating-related businesses and equipment. The trailer does not show Vulcar Marine staff, a manufacturing site or a vessel fitted with one of its engines.

Beyond the banner at Brian's Boat Works & Marina, no further details about Vulcar Marine's operations have been publicly shown. Its known role is limited to making engines for boats and other watercraft under the Vulcar company name. Rockstar's trailers, official screenshots and the August 2026 Extended Look have not provided additional information about the business.
