The tapering tail is no secret among scientists for improving stability and fuel efficiency. Many high-mileage concept cars feature just such a design to smooth the aerodynamics of the vehicle. Now imagine applying the same concept to container trucks that log more miles in a year than most of us travel in five.
A Dutch public-private enterprise did just that, adding a 6 foot long tail to the end of a tractor trailer truck. The results from two years of testing were a 7.5% increase in fuel efficiency, and thus a similar decrease in emissions.
