I hope not. Over the last 10 years, they've had literally the ONLY decent American-made sports sedans and wagons, and really the ONLY option under $100k for anything with real horsepower.
Of course GM has the Corvette, wonderful car, but really only practical for empty-nesters who don't need a back seat. Ford has done some impressive things with the Mustang, but it's a tiny car with a nearly useless back seat, and they've never been as nicely-outfitted as the top models of Charger or Challenger.
If Dodge doesn't get their feet back under them, our only really viable choice for replacing high-horsepower Chargers will be Mercedes AMG cars. The Merc's are amazing vehicles, but roughly double the price for equivalent performance and body type. That's just a "no go" situation, for many.
Of course the Tesla P90D's and the like are another option, but awful old designs at this point, and nearly into AMG pricing territory.
