One-off Hoonicorn RTR · ASD Motorsports tubular chassis · no VIN or production-Mustang equivalence claimed

Hoonigan's 2014 launch packet calls the Hoonicorn a completely unique, one-off, all-wheel-drive 1965 Ford Mustang notchback. It was a two-year collaboration among Ken Block, Hoonigan and Vaughn Gittin Jr.'s RTR, built at ASD Motorsports. The body reference is a 1965 Mustang, but the packet specifies a full tubular chassis, carbon-fibre panels and one-off all-wheel-drive hardware. Joyride therefore treats it as an individual custom build, not a factory 1965 Mustang trim or a shortcut to the Mustang family history.

In its Gymkhana Seven specification, the 410-cubic-inch Roush Yates Ford V8 was naturally aspirated and rated at 845 hp and 720 lb-ft, driving all four wheels through a six-speed Sadev transmission. The licensed photograph shows that actual V1 Hoonicorn running at Goodwood on June 26, 2015; it is not a same-model substitute or the later V2 appearance.

Hoonigan's 2016 V2 packet says Block and his team improved the same Gymkhana Seven Hoonicorn rather than building a second car. They added two turbos, methanol fuel and 21 pounds of boost to the 410-cubic-inch engine, producing a stated 1,400 hp at the crank. Block House Racing's current garage page continues to describe the V2 among the Block family's racecars and special projects, but Joyride does not convert a garage listing into a current legal-ownership claim. No VIN, chassis serial, present title holder or game-compatible representation is asserted.

Where the car went next

  1. 2012–2014The one-off takes shape

    Block, Hoonigan, RTR and ASD Motorsports developed the tubular-chassis, all-wheel-drive custom build over roughly two years.

  2. November 2014V1 debuts

    Hoonigan publicly introduced the naturally aspirated 845 hp Hoonicorn for Gymkhana Seven.

  3. June 26, 2015The V1 at Goodwood

    Neil photographed the actual Hoonicorn running at the Goodwood Festival of Speed; the image predates the twin-turbo V2 conversion.

  4. 2016Rebuilt as V2

    The existing Hoonicorn gained twin turbos, methanol fuel and a stated 1,400 hp for its next video project.

  5. Reviewed October 7, 2026Listed in the Block family garage

    Block House Racing lists Hoonicorn V2 among the family's racecars and special projects. That dated listing is not presented as a title record.

Sources for this story

Hoonigan's V1 and V2 packets establish a single one-off custom car, its collaborators, tubular chassis, two powertrain states and Block's driving role. The 2015 photograph shows the actual V1 before the V2 conversion. This is a custom-build creator/driver association, not a legal-ownership claim; Block House Racing supplies dated family-garage context, not proof of present title. No VIN, chassis serial, factory-production identity, current title holder, complete Mustang-family coverage, exact Joyride catalog match or compatible game vehicle is claimed.

Why this is the actual car
  • Photo identity evidence

    Photographer Neil identifies the June 26, 2015 Goodwood Festival of Speed image as Ken Block's Hoonicorn and licenses it CC BY 2.0.

  • Photo identity evidence

    Hoonigan's contemporary V1 packet identifies the 845 hp one-off Hoonicorn, its collaborators and its Gymkhana Seven role.

  • Photo identity evidence

    Hoonigan's V2 packet establishes that the Gymkhana Seven car was subsequently converted to the 1,400 hp twin-turbo specification, dating the photograph to its V1 state.

The matching photographer, venue, date and vehicle history establish the identification; the chassis stamp is not visible in these photographs.
