From your article: "fuel savings of 3.2 to 5.3%" from rounding of the front The article itself states there are bigger benefits to be had modifying the trailer: "Further aerodynamic improvements are possible, notably on the trailer. For example aerodynamic add-ons, such as tails and side wings, could help deliver even higher significant fuel savings. Their potential is explored in another T&E briefing. [23]" The referenced article: https://www.transportenvironment.org/wp-content/uploads/2021/07/2010%2001%20aerodynamic%20hgvs%20report.pdf https://www.transportenvironment.org/wp-content/uploads/2021... That article shows a variety of tail modifications which have higher effectiveness than rounding the front.
