Challenger: better mileage from automatics (updated)

by David Zatz on

As expected, EPA fuel-economy ratings of the Dodge Challenger increased when the eight-speed automatic became standard, though not as much as some had expected based on comparisons to the larger Chrysler 300 and Dodge Charger V6.

With a V6 engine, the Challenger is now rated at 19 mpg city, 30 highway — up from 18/27. The highway mileage benefits from the eight-speed’s wide range, allowing the engine to loaf at around 1,500 rpm at 70 mph. When the Charger moved to the eight-speed automatic, 0-60 times with the V6 dropped to 6.6 seconds, equalling to the 2006 Hemi Charger.

Economy drops when one moves to the 5.7 Hemi V8, which returns 16 city, 25 highway. Moving up by nearly a hundred horsepower to the 392 V8 (6.4 liter Hemi) only costs 1 mpg, city: it returns 15 city, 25 highway, up from 14 city, 23 highway last year.  The V6 gained 1 mpg city, 3 mpg highway.

With the manual transmission, fuel mileage is the same as in 2014.
