Not sure if this is fact (just assuming here) but I think the decision makes long term practical sense. Unlike a traditional car (also with a black raw plastic liner) the rear fender section of the wheels will be constantly pummeled by snow, rain, abrasive, rock, etc. Wouldn't take long for the trailing edge of the pretty front fenders to be paintless in no time. I think the same will hold true for the rear along with the certain scratching and damage from wheel removal, repair, etc. While my assumptions are probably just that, at this point I haven't seen any evidence of Elio just "Winging It" in regards to the build construction or cost. There is as they say "a method to their madness". At least thats what I am going with!! Another fender related assumption, I would guess along with better aerodynamics lowering the front fender edges would further assist in water dispersion. With the original design, I would bet in rainy weather all you would see from both side windows would be a rooster tail of water similar to a speed boat. Again, just an assumption but I do Love the changes and directions they are headed. As long as it ends up at the finish line!!!!
