It's not that surprising really. GM does basically nothing to promote the Camaro. It's been dying a slow death for years. The Mustang is cool, but I think a lot of Mustang fans were turned off by the redesign in 2015. Meanwhile, Dodge has been promoting their muscle car image non-stop for the past 7-8 years. Not to mention, the Challenger is both the best looking and most practical vehicle of the three (I may be slightly biased).
I work for Stellantis and recently attended a meeting where one of the higher ups at Dodge had a presentation for us. They basically showed how they are going to transition over from gas powered to electric muscle cars. It seems like they've done their research and that they know what they're doing on paper, but from my own personal perspective I think it's the wrong direction.
One thing that was promising is they discussed how they were tired of people saying "Teslas are faster"..."that Tesla beat that Scat Pack or Hellcat", etc. The guy basically alluded that the new electric muscle car they are going to be producing soon will be faster than the quick Teslas and also cost a fraction of a Tesla, all while looking a lot better than a Tesla. Basically they had their eye on Tesla and want to smoke them.
I hope they have the electric muscle car available for lease through our employee program so I can try one out without committing to it. I'm assuming they're going to be really fast. But it just won't be the same without the engine/exhaust sounds of ICE. Time will tell how this electric crap works out I guess.
