How does payload weight affect truck fuel consumption?

Rule of thumb for Class 8 trucks: each additional 10,000 lbs of payload reduces fuel economy by approximately 0.2-0.5 MPG (on 6-8 MPG baseline). A fully loaded 80,000 lb truck uses 20-30% more fuel than running empty at equivalent speed.

What is cost per ton-mile?

Cost per ton-mile = total operating cost per mile / payload tons. At $1.50/mile total cost and 20 tons: $0.075/ton-mile. The EPA SmartWay program benchmarks freight carriers and target <$0.10/ton-mile for efficient operations.

How does aerodynamics affect heavy truck fuel consumption?

Aerodynamic drag accounts for 50%+ of fuel consumption above 55 mph for Class 8 trucks. A fully spec'd aerodynamic truck (fairings, side skirts, boat tail, wheel covers) improves fuel economy by 10-15% vs base spec. Worth $5,000-15,000 in equipment investment for interstate routes.
