Mileage will vary, but there are official NHRA certified quarter mile times for the Hellcat at 11.20 with street tires, 10.80 on drag radials. I'm biased as I own a '13 Challenger, but in real world driving experience, the Challenger wins hands down. Better styling, more comfort for all passengers. Real trunk in the back to haul the groceries. Performance numbers do mean bragging rights, but none of us drive at 10/10ths of a cars performance all day long.
