Welcome to Issue 47. Twelve years ago I left Heavy Duty Trucking magazine because the industry kept trading measurement for marketing — and readers deserved better numbers than the spec sheet attached to the press kit. This week that means a 2025 F-350 with the high-output 6.7L Power Stroke, run cold on our chassis dyno in Loveland, then loaded to its' max tow rating up the grade at County Road 18E. Independent testing is slower than republishing a press release, slower than chasing the quarter-mile click-bait, and slower than the SEO farm that scraped it before we hit publish.
It is also the only way the 3.8 million of you who stop by each month can trust the horsepower figure, the fuel-economy number, or the 0–60 estimate. Everything we publish is run, weighed, or logged by our own staff — nine of us hold ASE certifications, four of us came out of OEM powertrain programs, and 1,247 of you let us plug a telemetry box into your truck. That is the trade. You give us the data; we give you the answer.
