Engine Specs publishes plain-English guides to engines, model lineups, and car ownership for the US market. This page explains what we cover, how our articles are researched, and how to reach us when something needs correcting.
What we cover
Our articles focus on engine specifications and output figures, trim and pricing breakdowns for current models, maintenance how-tos, and explainers on everyday ownership topics such as fuel octane, wheel alignment, and electric-vehicle charging.
How our articles are researched
Articles are published under the Engine Specs name and compiled from published sources: manufacturer announcements and specifications, government data from agencies such as the Environmental Protection Agency, the Department of Energy, and the Energy Information Administration, and established automotive publications and industry research. Guides that rely on specific sources name them at the end of the article.
Prices, output figures, and model-year changes can change after publication. Where a guide lists them, we note the period the figures reflect and update the article when we learn they have changed.
What we don’t do
We don’t road-test vehicles, and we don’t publish first-person driving impressions or ownership stories. When a guide describes how a car behaves, it summarizes the manufacturer’s engineering and widely reported characteristics rather than claiming a personal test.
Photos
When we use photos from Wikimedia Commons or other openly licensed sources, the photographer and license are credited in the caption, and the license details are kept on file.
Corrections and contact
If you find an error, a figure that has changed, or a photo credit that needs fixing, please tell us through our contact page. We review every report and update the article when a correction is warranted.
Our core guides were rewritten in September 2026 under these standards.
