Ford reportedly showed dealers a four-door Mustang prototype.

People who saw it described it as looking like a Porsche Panamera.

The automaker also revealed to dealers a new mainstream crossover with a hybrid powertrain and a starting price of around $25,000.

Ford’s four-door Mustang has long been rumored, but the performance sedan is finally getting closer to becoming a reality. The automaker reportedly showed a prototype to dealers last week, but it remains unclear when such a car could go on sale.

Ford executives referred to the Mustang as the "Mach-4" two years ago, when the model was reportedly first revealed in a private dealer meeting. Sources told Automotive News that the car looks like a Porsche Panamera.
