Being an official reviewer for DOE’s Annual Merit Review for Vehicle Technologies projects, I have a front seat to the future…

To build the Starship, Shell teamed up with the AirFlow truck company to ruthlessly apply all of the best aerodynamic tricks and materials science hacks to the design of the truck in search of something more important to big trucks than simple miles-per-gallon: ton-miles per gallon. A truck's ton-miles per gallon figure compares the vehicle's fuel efficiency with the amount of cargo being carried since that dramatically affects how hard a diesel engine has to work.
What was the end-result of all this technology and effort? Well, a typical long-haul diesel truck will weigh around 57,000 pounds, including a cargo load of 22,500 pounds. The Starship gross vehicle weight was right around 73,000 pounds, 39,900 pounds of which was cargo, despite that, the Starship averaged 8.94 miles per gallon versus a typical truck's average of 6.4 miles per gallon. The Starship's best mileage was just over 10 miles per gallon.
