Ken Block's '65 Ford Mustang Hoonicorn V1

The Hoonicorn V1 began life as a 1965 Ford Mustang fastback body shell — but almost nothing else of the production car remains. ASD Motorsports designed a custom tubular chassis with full roll cage, door bars and underbody protection; the running gear is a SADEV SC-90-24/170 transaxle paired with a Roush-Yates 6.7-litre V8 (some sources cite 5.8L; the build's specifications were revised across its life), producing 845 horsepower and 720 lb-ft of torque on the V1 spec. Most consequentially, the Hoonicorn was the first all-wheel-drive performance Mustang — the AWD drivetrain made the car capable of the rotational-grip stunts Block had previously needed his rally Fiestas and Foci to perform.

Gymkhana SEVEN: Wild in the Streets of Los Angeles, released to YouTube on 19 October 2014, was the Hoonicorn's introduction. The Hoonigan-produced film took the Hoonicorn through downtown LA — drifting around the LA Convention Center, threading the Anaheim/Olympic interchange, and ending with a freeway-burnout finale. The video crossed 100 million YouTube views and is widely credited with shifting Gymkhana from rally-car branding exercise into a stand-alone action-sports format. The Hoonicorn V1 stayed the hero car through Gymkhana NINE (2016) before being upgraded with twin turbochargers — 'Hoonicorn V2' — for Climbkhana One (Pikes Peak, 2017).

Ken Block died on 2 January 2023 in a snowmobile accident in Utah, aged 55. The Hoonicorn was retained by the family and has been displayed at events including the Petersen Automotive Museum's Block tribute. LEGO® 77262 is the first Speed Champions release in the post-Block era and the first LEGO® set explicitly tied to the Hoonigan / Gymkhana legacy. The set's V1 specification is significant — V1 is the Gymkhana 7 spec that became the car's defining visual identity.
