So a 4000 pound car with 250 HP gets 30 MPG compared to a 30K pound motorhome with 250 hp that gets 8 MPG because of frontal area?
This year both Freightliner and Peterbilt streamlined one of their production models and trailer. Both were able to achieve 10 mpg. The Freightliner was 76,000 GCW and the Peterbilt was 65,000 GCW. The industry standard for a regular combo is 5-6 mpg. Aerodynamics plays a huge role once up to speed.
