2015 Dodge Viper GT: Fuel Economy Update for April and May

by Travis Langness, Automotive Editor on June 14, 2016

2015 Dodge Viper GT

We've been remiss. We didn't update our long-term 2015 Dodge Viper's fuel economy last month. As an apology, here's a two-month update on the V10 powerhouse that currently sits at the top of our in-house leaderboard for worst MPG.

2015 Dodge Viper: Fuel Economy Update for March — Still Double Digits

by Kurt Niebuhr, Photo Editor on April 13, 2016

2015 Dodge Viper

When we weren't scything through traffic in our 2015 Dodge Viper, ah who are we kidding. All we do is scythe through traffic.

March saw us put another 1000 or so miles on the clock, discover that indeed exhaust pipes get dirty, admit to a too early damnation of a magnificent and visceral beast, and discovery of the joys of erranding around Los Angeles in our blue meanie. Did I mention we scythed through traffic? 'Cause we did that, too.

2015 Dodge Viper GT: Fuel Economy Update for February — Winning With Single-Digit MPGs

by Mark Takahashi, Automotive Editor on March 7, 2016

2015 Dodge Viper GT

It's been a slow month for our long-term 2015 Dodge Viper, logging only 753 miles in January. That's mostly because it went in for an extended service visit (details to come, I'm sure).

2015 Dodge Viper: Fuel Update for January That's More Like It

by Kurt Niebuhr, Photo Editor on February 11, 2016

2015 Dodge Viper

Expecting good fuel economy from an 8.4-liter V10 when it's used as a daily driver is, well, dumb. And our 2015 Dodge Viper is doing absolutely nothing to change anyone's expectations there. But what about the rest of the car?

In January we put another 1,000 miles on our quasi-supercar, and as a result we've experienced the pains — and costs — of that reality. For one thing, the nose of our beautiful blue Viper is starting to show the wear and tear that 17,000 miles does to the front end of a car. The mileage didn't just get to the paint either, as we went ahead and replaced all four tires at a head rush-inducing price of $1800.

 But tires and paint are just hardware. What about the liquidware?

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.

2015 Dodge Viper: Doesn't Want a Full Tank

No, that title doesn't refer to the diminutive center on your high school basketball team. That's Short Phil. I'm referring to a recurring problem when refueling our long-term 2015 Dodge Viper.

2015 Dodge Viper GT: Fuel Economy Update for September - New Highs, New Lows

by Mark Takahashi, Automotive Editor on October 13, 2015

2015 Dodge Viper GT

No surprise that our long-term 2015 Dodge Viper fuel economy average is adjusting to a lower figure after its initial cross-country trips. In September, it fell half-a-mile per gallon, but it was well worth it. We also scored a new high-mpg result, too.

2015 Dodge Viper: Fuel Economy Update for August - Sliding Back To Reality

by Brent Kurt Niebuhr, Photo Editor on September 21, 2015

2015 Dodge Viper

The cross-country highway party known as Carlos and Jay's Hypermiling Love Fest is over. Now our 2015 Dodge Viper is back in the real world, the world of traffic, tempting mountain roads and more traffic. Oh, and meatheads like me.

In August, we plumbed the depths of its vast reserves of power. We've tached it out, flung it around and muscled it through about a 1,000 miles of typical Los Angeles living. Reality is calling.

2015 Dodge Viper GT: Across the Country, By the Numbers

By now you've read about our coast-to-coast drive and return trip to Los Angeles in Edmunds? long-term 2015 Dodge Viper. If not, go ahead. We'll wait.

Here's a breakdown of our round-trip drive across the country in numbers:

2015 Dodge Viper GT: Fuel Economy Update for June - Single Digits in a Month of Restraint

July 20, 2015

2015 Dodge Viper GT

The first fuel economy report for our 2015 Dodge Viper is not going to paint a good picture.

We took it on a photo shoot. Rarely left the city. Observed engine break-in rules and generally just puttered around, using all of the rev range waiting to cross the 1,500-mile line.

It'll get better. And probably much worse.

2015 Dodge Viper GT: Outperforms EPA Highway Rating on Road Trip

July 15, 2015

2015 Dodge Viper GT

Last time we discussed the fuel economy of the 2015 Dodge Viper, we had fewer than 1,000 miles on the odo, and most of those miles were from shuffling around the west side of Los Angeles.

But then I took it on a road trip. 700-plus miles, no traffic, minimal stopping. Plenty of gas stations, so no need to be conservative with the go pedal.

2015 Dodge Viper GT: Death Valley Break-in Road Trip

July 12, 2015

2015 Dodge Viper GT

As Dan mentioned, our 2015 Dodge Viper has a frustratingly long break-in period. 1,500 miles to be exact.

Well, frustratingly long if you're not me. I loves me a good break-in road trip. I like the long hours behind the wheel. I like that you can't stay at a certain speed for too long. I even like that you can't take full advantage of all the power. It keeps me from even needing the ol' radar detector.

The Viper needed 700 more miles when I got the keys. The loop from Los Angeles to Death Valley to Las Vegas and back is about that far.

2015 Dodge Viper: Viper, No Viping

June 30, 2015

2015 Dodge Viper

Bring home something like a 2015 Dodge Viper GT and the temptation to show it off, open it up and generally revel in the 645 horsepower and 600 pound-feet of torque you just bought is irresistible.

But Dodge and SRT don't want you to go hell-bent for leather in the first mile. In fact, they strongly suggest you hold off until 1,500 miles appear on the odometer. During that time the break-in period for SRT-sourced engines is pretty specific, and it consists of four phases that get gradually more permissive. Page 21 of the Viper manual spells it all out.

This is why you don't see any motion blur in the photograph above. Note also that the tachometer is pointing at a piddling 2,000 rpm. I am abiding by Phase I guidelines, which apply between 0 and 100 miles: no extended idling, go easy while braking, accelerate gently to no more than half throttle, shift before 3,500 rpm and never exceed 55 mph.

2015 Dodge Viper GT: Introduction

June 26, 2015

2015 Dodge Viper GT

"The last of the muscle cars!" "The end of the V8!" "We'll never see anything this good again." We've heard these proclamations repeated and retracted more times than we can count, and knowing that, we're confident in saying the Dodge Viper is certainly the last of the truly bonkers muscle cars.

At least that's what we said five years ago when we introduced a 2009 Dodge Viper into our test fleet.

Fortunately, we were mistaken. The Dodge Viper is very much alive and kicking.
