The Mustang is now an SUV. In related news, the government has decreed that all dogs have five legs and no tails. No one could reach an agreement about cats.
Actuallg, there is an unwritten rule about cats. Any single woman who has more than 3 cats just buy all wind in boxes.
The Mustang is a 2-door sport coupe, not an SUV.
The Mustang Mach-E is a 4-door hatchback "crossover" and a "Mustang" in name only.
Ford pulled a similar stunt with the "Bronco" name, releasing both a serious body-on-frame off-road Bronco suitable for the Rubicon or Moab, and a "Bronco Sport" unibody compact SUV suitable for getting groceries. Like the Mach-E, it shares nothing but a name with it's namesake.
