Truck below (as been posted here before, but photobucket ate the images) is from a report you can read: Fairing Well. It's on page 29. Rounded leading edges reduced the drag by 30%.
they are using Square edges now on the rear..

it's proved to be more aerodynamic also better hood designs push the air from the top of the hood to the sides rather then over the top of the SUV.. I see this on my tahoe hybrid .. at lest that is what is happening to the rain water on the hood.. these are both 2008 models one hybrid and the other non hybrid

one 0.34Cd and the other 0.38cd

the square rear edges is standard from the 2015 model onwards
