Does anyone know how much gas mileage a 1970 Dodge Charger gets?!?!?
As has been pointed out, it depends on the engine, not to mention gearing. Standard were the 318 and the Slant 6. The former should average about 16-17, I reckon. The Slant 6 should reach the 20s on the highway if you’re lucky, but it’s a heavy car with a small engine needing all it has to push it. The 383-2 is really not much worse off than the 318, but has a lot more torque. I think averaging 15-16 would make sense. With a 4bbl. you could expect 13-14, maybe less. The hi-po engines – the 440-4, 440-6, and Hemi – will impact mileage due to the high performance nature of the cars, if not the gearing. The 440-4 can probably run as efficiently as a 383-4, but that’s with a light foot and higher gearing. Otherwise, I would expect to average 12. With the Six Pack, I think you’d be lucky to average the same. And I know an old Consumer Guide test that got 6mpg with the Hemi, although that’s probably an extreme – it’s probably an 8-12 mpg car.
