The Hidden Fuel Cost of Mechanical Degradation

Our autonomous research agent analyzed a heavy-duty fleet and discovered that aftertreatment system health has a measurable, quantifiable impact on fuel consumption.Every fleet manager knows that a poorly maintained vehicle costs more to operate. But how much more, exactly? And which mechanical systems have the biggest impact on fuel?

Fuel consumption is one example. It depends on dozens of factors: vehicle manufacturer and model, engine size, speed, gear selection, ambient temperature, terrain, cargo weight, driver behavior. Isolating the effect of mechanical condition from all of that noise has historically required significant analyst and engineering resources.
