2009 Dodge Challenger R/T: Belated Road Trip MPG
December 07, 2009
Some days I ago I wrote here that I'd takena 1,000-mile road trip to Willows, California, in our 2009 Dodge Challenger R/T, but I neglected to follow up with fuel economy totals. That changes today.
Totaltrip mileage was 1,277 miles and the Challenger went through 61.266 gallons for an average of 20.8 mpg against an EPA rating of 16 mpg city, 25 mpg highway. The combination of a big gas tank (19 gallons),the six-speed manual transmission'sconservative top gear (0.50) and the 3.73 final drive (it would be 3.91 if we'd gotten the 20-inch wheels) give the oversized coupe incredible range on the highway.
My longest tank spanned 390.9 miles, after which I put in 17.054 gallons for an average of 22.9 mpg.
I backed off on my usual manic pace for most of the nighttime drive back to Los Angeles. Keeping a 75-mph pacesignificantly reduced consumption, and I averaged 25.8 mpg over 342.3 miles (putting in 13.270 gallons). This is impressive, considering our Dodge weighs two tons and doesn't have cylinder deactivation.Had I been able to wait longer to fuel up, I would easily have seen 450 miles on this tank. (Oddly, no one has ever driven more than 396.8 miles on a single tank inour Challenger R/T.)
