DCX has stated that the new Challenger would be built in its Brampton Ontario assembly plant in Canada.
I researched the plant (nothing better to do) and found that its production capacity is 968 cars per day (19,360 per month). The factory employs 3,500 employees and uses 507 robots.
The plant is situated on 270 acres and has 3 million square feet of floor space.
