What was the name of the special NASCAR-influenced Charger model introduced in 1969 before the winged Charger Daytona?

Charger 500. The unique features of the Charger 500 were a flush-mounted grille, exposed headlights, and a more aerodynamic rear window. It performed only marginally better than the standard Charger on the tracks, though, so the Charger Daytona was introduced later in the 1969 model year. It was a big improvement over the Charger 500, but was eventually outlawed by NASCAR after having won many races.
