If the Challenger is such a winner, why is it going away?

Because at the price point, there just aren't enough buyers every year to keep the production line open and it doesn't have enough of a following at a high price point to go into a niche line like the Corvette.

It's not new; the early Dusters / Demons, Challengers / Barracudas and Charger / Roadrunners were never manufactured in the same number as their GM counterparts:

Buick Apollo (Chevy Nova design)
Buick Century / Regal / Skylark / GS
Chevy Camaro
Chevy Chevelle
Chevy Malibu
Chevy Monte Carlo
Chevy Nova
Oldsmobile Cutlass / 442
Oldsmobile Omega (Chevy Nova design)
Pontiac Firebird
Pontiac Grand Prix
Pontiac Tempest / LeMans / GTO
Pontiac Trans-Am
Pontiac Ventura (Chevy Nova design)

...and let's be honest, the car's current legacy is having someone stealing one and doing donuts in an intersection in a ghetto neighborhood. It's not a legacy of a real muscle car out racing on the roadways.

I had one!

Yes, that’s exactly the legacy—this is now a major douchebag/feral car.
