Dodge Viper data analysis

How Dodge Viper combined fuel economy varies

Across 3 configurations recorded for the 2015 through 2017 Dodge Viper, combined fuel economy runs from 14 MPG to 15 MPG. The strongest figure belongs to the 2015 Dodge Viper (Man 6-spd, 10 cyl, 8.4 L) at 15 MPG, and the weakest to the 2017 car (Man 6-spd, 10 cyl, 8.4 L) at 14 MPG — a spread of 7%. The narrow spread means any year of the Dodge Viper in this table behaves much like the others, so you can shop on price, condition and mileage rather than chasing a particular model year.

What changed for 2017

Average combined fuel economy for the 2017 Dodge Viper is 14 MPG, against 15 MPG for the 2016 car — it fell by 1 MPG. Buyers who care most about this figure should look at the earlier model years in the table above before assuming newest is best.

How to read this Dodge Viper data

This page lists every 2015 through 2017 Dodge Viper record we hold for this measurement — 3 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.

Where these Dodge Viper figures come from

Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The Dodge Viper record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.

Our Real-World Speed MPG Adjuster re-scales the Dodge Viper EPA highway result with a quadratic drag term (mpg = hwy ÷ (1 + k·(v² − 60²)/60²), k = 0.55 for trucks, SUVs and vans, 0.42 for cars). Wind, roof racks, and a heavy right foot make it worse, never better.
