Vehicle calculations are often exact only on paper. This cluster keeps the base result while making rolling radius, gearing, wheel measurements and performance-input sensitivity visible.

Cost-per-mile stress test & trip budget
Use the core economy and fuel price above, then turn the unit cost into a trip decision. Apply a realistic economy degradation and price stress, compare baseline versus stressed cost per mile, and calculate the fuel cost for a route length.
—Baseline / mile
—Stressed / mile
—Stressed trip fuel
—Stressed / 100 mi

Cost-per-mile isolates fuel operating cost; it does not include maintenance, tires, depreciation, tolls or insurance. Keep those costs separate instead of hiding them inside the fuel calculation.
