The 1969 Dodge Charter.
The 500 and Daytona had improved aerodynamics, which were primarily a flush grille and back light on the 500, but were radical on the Daytona, which had a Cd (coefficient of drag) of 0.29, a number not bettered on production cars for many decades. Both cars had the 440 Magnum as standard equipment, with the 2X4-BBl 426 Hemi as the only engine option. I preferred the hemi as the 440 had a tendency to “bog” on launch. The Daytona set a world closed-course record of 200.45 MPH at Talladega, Alabama in March, 1970, in a car that had been stolen on the streets of Los Angeles and recovered by the LAPD.
I personally road in a hemi in Los Angeles, one with a holly three on it, and we went from 50 to 140 on a freeway on ramp. (And burned a quarter tank of gas)
