Let’s take Porsche, for example. The venerable 911 sold just above 30k units, while the Cayenne more than doubled that at just under 67k units. Even the Macan almost doubled that with more than 59k units. The sports car won’t pull any company out of a sales slump, there isn’t enough of a market for it. In comparison, the total number of 2022 Challengers and Chargers with the Hellcat engine is just over 6,500. That does not include Jeep or Ram, but I can’t imagine it wasn’t stratospheric.
I love the Viper, but even I know when it’s time to take a horse out back and ya’know…
Ford made the GT in very limited numbers, the Corvette is, well, the Corvette and unless a meteor strikes Kentucky, I don’t see that ever ceasing to exist. But the Mustang and the Camaro are in the same position as the Challenger. The more strict emissions standards coming and Ford already played their hand with the “Mach-E”.
Other manufacturers:
Toyota - Pseudo Supra
Nissan - 400Z (still slow, still heavy, still on an aged platform)
BMW - See Toyota
Mercedes - Limited production AMG-GTR/GTS
Porsche - See first paragraph
Ford - Mustang, Mach E (SUV)
Chevrolet - Corvette (Icon of a vehicle, Chevrolet would rather die than stop production)
I won’t bother to include Ferrari, Lamborghini, or other Italians as they are all pretty limited in their production across the board (Yet both Ferrari, Maserati and Lamborghini have or are about to jumped into the SUV ring). Even Aston Martin has an SUV now.
I’m not sure where you going with the “Jeep is not reliable” stuff. The 4.0 straight 6 is bullet proof and is in most of their line up. Maybe you mean the FWD platform Jeeps, which were always trash, even when Daimler had it’s hands in Chrysler/Jeep.
The U.S. isn’t even the top purchaser of SUVs at this point (China being #1).
