How many miles per gallon does a 1970 dodge charger have?

The miles per gallon (MPG) for a 1970 Dodge Charger varied significantly depending on the engine option. There wasn't a single MPG figure. A smaller engine would get better gas mileage than a larger, more powerful one. Expect a range from a low of around 10 MPG for the larger V8 engines to perhaps a high of around 14 MPG for a smaller engine, if driven conservatively. These are estimates, and actual mileage would depend on driving style, vehicle condition, and other factors.
