2015 Dodge Viper GT: Fuel Economy Update for November — Not Best Choice for Obama's Showcase at Paris Climate Talks

by Brent Romans, Senior Automotive Editor on December 2, 2015

2015 Dodge Viper GT

If nothing else, our 2015 Dodge Viper is staying true to itself. As has been the case since we got it, the Viper's fuel economy hovered in the mid-teens on good days this past month. Lay into the throttle with regularity — the only way some of our staff know how to drive this Viper — and fuel economy plummets into the single digits at fill-up.

Fun? Heck yes! Fuel efficient? Not really.

For the past two months (we didn't report on fuel economy for October), we averaged 12.1 mpg. That dragged down our lifetime average, which was 16.1 mpg previously and now stands at 15.3 mpg. Prior lifetime highs and lows for fuel economy fill-ups remain unchanged.

Interestingly, my co-worker Mark Takahashi wrote about his experience on a couple of fill-ups where the Viper wouldn't accept a full tank of gas. The same thing happened to me on one of my fill-ups. But a subsequent one was fine and resulted in a completely full tank.

Is it the car, the type of pump, or perhaps a combination of both? Our fuel log also has a few notes from earlier this year that would also indicate some short fills. This inconsistency is perhaps throwing off our mpg tracking a bit.

But on a Viper, I don't think anyone's going to notice much.

Worst Fill MPG: 6.4
Best Fill MPG: 27.2
Average Lifetime MPG: 15.3
EPA MPG Rating: 15 Combined (12 City/21 Highway)
Best Range: 294.3 miles
Current Odometer: 14,465
