What is the make and model of this mid-size car with a powerful V8 engine that later was developed into a popular muscle car?

While the Charger didn't become the muscle car it's known for being today until later on, the first generation of this car went into production in 1966. The original vehicle was designed to be a mid-size car with an extremely powerful motor.
