Holden Special Vehicles, abbreviated HSV is the officially designated performance vehicle division of Australian motor automobile manufacturer Holden. HSV modifies Holden products such as the Commodore, Caprice and Ute giving them unique body-work and alloy wheels, up-spec interiors, and improved all-round performance thanks to upgraded engines, brakes, transmissions and suspension. Over the years HSV have built an array of modified vehicles, most of which have been based on the Commodore and powered by either Holden or GM sourced V8s.
