The Vector brand, founded in 1971 by Gerald Wiegart, initially promoted its first prototype, the W2, in the late 1970s, with the production of the twin-turbocharged W8 commencing in 1989. The development of the W8’s successor, the WX-3, faced setbacks when Megatech acquired Vector Aeromotive and removed Wiegart, who retained the design copyrights for the WX-3 prototype.
Following Megatech’s acquisition of Lamborghini in 1994, the company used the Diablo’s platform to develop the M12. This was the first vehicle produced after Megatech’s takeover of Vector from Jerry Wiegert. The M12 featured a chassis extended to accommodate carbon-reinforced fiberglass bodywork similar to the WX-3 coupe.
Powered by a 5.7-liter Lamborghini V12 engine with dual overhead camshafts, four valves per cylinder, and electronic multiport fuel injection, the M12 produced 492 horsepower, matching the Diablo. A total of 17 M12s were built, including three prototypes.
