The Shelby GT500 Plastic parts to hold the car's brake lines will be produced using 3D printing. Compared to stamping out parts, 3D printing is a relatively slow process -- the machine averages about five pieces per hour -- but it's very flexible in that one machine can make parts of almost any shape depending on the plans that are fed into it. (The same exact machine makes entirely different pieces for some Ford Raptor trucks.) This technique makes sense for a car like the GT500 since the car and its parts will be produced in low numbers. The first Shelby GT500 appeared in 1967. That car had half the horsepower ofthe new model. The original Shelby GT500s are considered among the most desirable American performance cars in the world. A 1967 Shelby GT500 Super Snake recently sold at a Mecum classic car auction in Florida for $2.2 million. The most recent Ford-produced Shelby GT500 before this one, which went out of production in 2015, produced 662 horsepower from a 5.8-liter V8 engine.
