Frequently Asked Questions
How much does a roof cargo box reduce gas mileage?
A roof rack or cargo carrier increases vehicle aerodynamic drag by roughly 10-20% at freeway speeds (65-75 mph), reducing MPG accordingly.
How does AC impact fuel economy?
Running air conditioning puts parasitic load on the engine or battery, increasing consumption by approximately 5-10% depending on ambient heat.
