From Joe's renderings, Unique Performance clayed up a full-size truck, then pulled molds for parts to create the Shelby GT-150. This work was done in Tecstar's Wheel To Wheel facility in Troy, Michigan, which builds ultra-high-end prototype vehicles for the top auto manufacturers in Detroit.

When it came to the GT-150, Hasty explains that "a lot of dealers had given us feedback. We had to make something that had at least an extended cab. We chose an extended-cab fleetside to keep the weight down as much as possible."

Giving the truck a rear seat would increase the customer base. Unique even considered a four-door in the lineup, but as Hasty says, "The four-door was so much heavier we decided to build the extended cab first, get feedback from consumers, and let them tell us which way to go."

Unique built three prototypes. The first one was used for durability tests. The second truck was mainly for development of interior components. The third GT-150 was the POC vehicle, seen here.

According to Iacono, "Some inspirations for the vehicle concept stem from the modern Shelby Cobra and the modern Shelby Mustang. The grille was designed from the signature Shelby look of the big gaping intake. But trucks have a bulkier, more utilitarian look that we wanted to streamline to keep within our performance stance. The front clip is 4.5 inches lower than the production vehicle. We also tightened up the tolerances throughout the vehicle, including the rocker panels and rear cover. We added 3.4 mm to the lower door and fenderwells to help define the performance stance. When designing a vehicle that'll be made on a small production run, there are numerous regulations. We wanted to push the envelope to develop a modern shape for a truck while sticking to the rules."

The hood, though not functional, features a twin scoop painted blue and offset with racing stripes on the driver's side, no doubt inspired by the Shelby Cobra race cars of the 1960s. Iacono says, "We wanted to shift the attention away from a tall cab line, so we used a quarter-panel stripe, also called a 'rookie stripe.' This made sense to the entire team, as it's an option used on many of the Vintage Shelby Cobra collectibles."

For now, the truck's been shelved and concept development slowed. Whether the truck moves forward is up in the air. Since the POC GT-150 "served its purpose," Unique sold it at Barrett-Jackson to show the public what the truck's about, serving as a gauge to get feedback. There may be no better venue for that than Barrett-Jackson, possibly the largest car auction in the world.
