Inside the $325,000 Mustang GTD’s Journey From Line to Hand-Built Supercar

Multimatic turns a standard Mustang body into a hand-built supercar using carbon panels, structural reinforcements, bespoke testing.

Overview

  • Each GTD starts as a painted body-in-white at Ford’s Flat Rock plant with major panels omitted before shipment to Multimatic in Markham, Ontario.
  • Multimatic plasma-cuts the C-pillars and rear seat area, removes the trunk floor, adds carbon reinforcements for the swan-neck rear wing, and installs an aluminum flat floor for NVH control around the rear transaxle and subframe.
  • The car receives GTD-specific carbon fiber bodywork including the roof, fenders, hood, diffusers, rockers, and bumpers, then moves through paint and ten hand-assembly stations.
  • Ford supplies dashboards and various production modules for installation with GTD-specific software, while bespoke components such as DSSV dampers and Brembo carbon-ceramic rotors are fitted by Multimatic.
  • The 5.2-liter Predator V8 is built in Dearborn, upgraded with a dry-sump system in Livonia, and dyno-verified alongside other subassemblies before final water-tightness checks, feature validation, and white-glove delivery to owners.
